WiFi Setup and Troubleshooting
During the initial installation, after the Installer setup, the thermostat will prompt you to set up WiFi and guide
you through the steps. If you are setting up WiFi after the initial installation has already been done, follow the
steps below:
1. On the thermostat, touch the Menu icon in the lower-left corner of the display.
Changing the Wi-Fi network or removing the thermostat from a network:
1. Select WiFi.
2. There is a slider labeled “Enable WiFi”. Make sure this is set to the right.
3. Touch Choose Network.
4. After a brief delay, the thermostat should show the available networks. Choose your home network from the
list.
5. If this is a secure network, it should prompt you to “Enter WiFi password”. After a brief delay the display
should show “Success! Your thermostat successfully connected to the network.” Touch the OK button.
NOTE:
If you did not successfully connect to the network:
1. The homeowner should Download the First Alert App from the App store or Google Play. If the installer
did the setup with Resideo Pro app and sent them an invite with the email they use for this account, that
thermostat will show in their app. If not, they will need to choose to add a device and follow on-screen
steps.
Connect to a Hidden WiFi Network
1. Touch MENU, then WiFi.
2. Touch Other.
3. Enter the network name.
4. Select the appropriate network security setting, then touch Select.
5. Enter the WiFi network password.
Unsuccessful WiFi Connection
If you are unsuccessful in connecting the thermostat to the WiFi network, you will see a Connection Failed
screen. Here are three specific reasons the connection might be unsuccessful.
Invalid Password
The password you entered is invalid. Check that you have the right password and try again.
13

No IP Address
The thermostat was unable to obtain an IP address from the router. Verify the router is correctly set up to
automatically assign IP addresses. This connection can take several minutes. If there is still no connection,
remove the thermostat from the wall plate for 10 seconds, then snap it back into place.
No Internet Link
The thermostat connected to the WiFi network but was unable to establish a connection to the internet. Check
the router settings and try again. Make sure the Ethernet cable is plugged into the router and try rebooting the
router if necessary.
WiFi and App FAQs & Troubleshooting:
Q: Will the thermostat still work if the WiFi connection is lost?
A: Yes, you can still manually adjust the temperature at the thermostat. However, some features such as
location-based temperature control (Auto-Away using geofencing technology) can only be managed through
the First Alert App and will not function without a WiFi connection. The thermostat will automatically reconnect
to WiFi once the network is restored.
Q: Is there a way to extend the strength of my WiFi signal?
A: The range (distance) of your WiFi signal is determined by your router. Try moving your router closer to the
location of the thermostat, or use a router with a stronger signal range.
Q: There’s an alert that says “WiFi signal lost” - what should I do?
A: Cycle power to the thermostat. This can be done with the switch on the side of the furnace, at the furnace
breaker or by removing the thermostat from wall plate and then reattaching after 10 seconds or more. Wait 5
minutes for the thermostat to reconnect or select an alternate network (if you have one) in the First Alert App
configuration menu. If the thermostat isn’t able to reconnect, you’ll need to troubleshoot the router to
determine the cause.
Q: The thermostat or app is showing "Datasync". What should I do?
A: Remove the thermostat from wall plate, wait 30 seconds, then reattach it. If the issue persists, unregister and
re-register the thermostat by deleting the thermostat from the app, then tap Add new device to reconnect it. In
the unlikely event that this doesn't resolve the issue, connect the thermostat to a hotspot or alternate network
for 24 hours, then perform a WiFi reset and reconnect it to your home network.
First Alert account and app questions
Q: Why haven’t I received an account activation email?
A: If you haven’t received an activation email within 5 minutes, check your Spam folder for a message from
customer-service@resideo.com. If you don’t see it, tap Resend to have the activation email sent again. If you still
don’t receive it, please contact the Technical Support team at 1-800-633-3991.
14

Q: Can I set up my thermostat with multiple users?
A: Yes. To add users, log into the First Alert App and tap the menu icon in the upper left corner. Select Users, tap
Invite Users and type in the email addresses of the people you’d like to invite. If they already have a First Alert
account set up, the thermostat and its location will automatically be added to their account. If they don’t have
an account, they’ll receive an email prompting them to download the First Alert App and create a new account.
Q: Can I set up location-based temperature control with multiple users?
A: Yes. Location-based temperature control (Auto-Away / geofence technology) will activate based on the last
person who leaves and the first person to return. Each user will need to create their own First Alert account with
a login ID and password. Two users should not share the same account. Each user will then need to enable
location-based temperature control.
Q: Why doesn’t a change I made in the app show up on the thermostat?
A: There may be a short delay when you make temperature and settings changes in the First Alert App. Wait a
few minutes, and if you still don’t see your changes on the thermostat, make sure the thermostat is still
connected to WiFi and restart your First Alert App.

Indoor Air Quality Control and Monitoring
Humidification
The thermostat reads the indoor humidity level and allows the user to set a humidification setting with or
without window protection.
Control Humidification Level (If thermostat has been wired and setup to control a humidifier)
1. Touch MENU and select Humidification.
Use the slider bar to select the desired humidity level. Typically this will be a setting between 35 to 55% RH.
2. Touch Save to save your settings.
3. If frost or condensation appears on the windows due to too much humidity, enable Window Protection and
adjust the level.
Window Protection
Window Protection limits the amount of humidity to prevent frost or condensation on windows. To use Window
protection, the ElitePRO™ Series Thermostat must know outdoor temperature from an outdoor sensor or the
First Alert App.
The thermostat prevents frost or condensation on windows by not allowing the humidifier to run above a certain
level. To prevent frost or condensation, the thermostat may turn off the humidifier before the humidity setting is
reached.
You can adjust the Window Protection setting by touching MENU, then select Humidification > Options >
Window Protection Level. Window Protection is set on a scale from 1-10. A setting of 10 represents poorly
insulated windows and a setting of 1 represents well insulated windows. A higher number automatically reduces
the humidity to help prevent frost or condensation on your windows. Use a lower number if indoor air seems too
dry. To prevent frost/condensation on your windows during cold outdoor temperatures, poorly insulated
windows require a higher Window Protection setting, which will limit how much your humidifier can run. After
you set the Window Protection setting, check for frost/condensation on your windows in the morning. If
frost/condensation is present, adjust the Window Protection setting to the next higher number and check for
frost/condensation on your windows the next morning.
38

Continue to adjust the Window Protection setting to a higher number until frost/condensation is no longer
present. If Window Protection is turned Off, the thermostat controls the humidity level to the user's desired
humidity setting. Frost or condensation may appear on windows.
Dehumidification
The thermostat reads the indoor humidity level and allows the user to set a dehumidification setting. The
thermostat controls the humidity level using the cooling system or a whole house dehumidifier.
Dehumidification Using the Cooling System
When set for A/C with Low Speed Fan, A/C with High Speed Fan or Reheat. The thermostat uses the cooling
system to reduce humidity by lowering the temperature as much as 3 °F below the current cool set point until
the desired humidity level is reached.
If humidification and dehumidification are both set up to operate in the system mode (Off), the thermostat will
automatically enforce a 15% deadband between the humidification and dehumidification settings. The
thermostat will automatically switch between humidification and dehumidification to maintain the desired
humidity level.
Dehumidification Fan Speed Priority
If the house has circulation issues to certain parts of the house when running in low speed, this feature will
allow the thermostat to use the high speed fan more often so that the conditioned air has better circulation
within the home. These settings are only available for select dehumidification types.
l
Low Speed Fan with Cool Stage 1 Only when the thermostat is set to humidify with low speed fan, and
humidity is high, and cooling is running at stage 1, always run with the low speed fan. When cooling goes to
stage 2, it ramps up to high speed fan.
l
Low Speed Fan Always Regardless of which cooling stage is active, the thermostat will exclusively use the
low speed fan when dehumidifying.
l
User Selectable The homeowner can set the high speed fan priority based on their comfort level (reachable
via Menu > Dehumidification > Options > High speed fan) If set to 10, the thermostat will always use the high
speed fan and never switch into low speed mode operation. If set to 0, the thermostat will only use the low
speed fan and never switch to the high speed fan when the humidity level is above the Dehumidification
39

setting.
Dehumidification Away Mode
If configured for dehumidification away mode by the installing pro, your system can be set to control indoor
climate while your home is vacant during the humid season. Before you leave, touch MENU, then select
Dehumidification Away Mode. Temperature and humidity will be kept at levels that protect your home and
possessions. When you return, touch Stop to resume normal operation.
Control Dehumidification Level (If thermostat has been setup to control a dehumidifier or AC with
High Speed fan)
1. Touch MENU and select Dehumidification.
2. Use the slider to adjust the desired Dehumidification level. Typically this will be a setting below 65% RH.
3. Touch options if you want to enable/disable the dehumidifier.
When disabled, the display will show off when viewing the dehumidifier setting screen.
4. Touch Save to save your settings.
NOTE:
If your air conditioner is used to control humidity, the temperature may drop up to 3° F below your
temperature setting until humidity reaches the desired level.
40

NOTE:
If humidification and dehumidification are setup to operate in the same system mode (Off) the thermostat
will automatically enforce a 15% deadband between the humidification and dehumidification settings. The
thermostat will automatically switch between humidification and dehumidification to maintain the desired
humidity level.
Ventilation
The thermostat can be set for the following ventilation types:
l
ERV/HRV
l
Passive (Fan Only)
l
Fresh Air Damper
l
Economizer (The Economizer settings are in a different section and used only when the ElitePRO™ Series
Thermostat is set for commercial application)
Ventilation Control Methods
Ventilation can be setup to meet either ASHRAE or Percent On Time settings. To meet these settings, the
thermostat will ventilate during calls for Heat, Cool and Fan. If the required ventilation has not been achieved
for ASHRAE or Percent On Time, the thermostat will force the ventilation equipment on.
ASHRAE
The thermostat operates ventilation equipment to meet the ASHRAE 62.2 ventilation standard based on CFM,
number of bedrooms, and square footage of the house.
ASHRAE 62.2 can only be met if the ventilation equipment is running. If the ventilation equipment is off for any
reason (outdoor ventilation lockouts, set up to turn Off during Sleep period, turned off by user, etc.), ASHRAE
62.2 is not met during those times.
Percent On Time
The thermostat operates ventilation equipment based on a percentage entered in the installer setup. For
example if Percent On Time is set to 50%, the ventilation equipment will run at random times during a 1 hour
period until it reaches a 50% run time (approximately 30 minutes). Default setting is 30%. Range is 10% to
100% in 10% increments.
l
NOTE:
This option is set by the user on the Ventilation screen. From Home touch Menu > Ventilation > Options >
Disable During Sleep.
Control Ventilation Level
1. Touch MENU, and select Ventilation. You can check or change the ventilation mode.
Mode:
l
Auto: Ventilation runs to follow either Ashrae requirements or % on time requirements programmed by the
installer.
l
Off: Ventilation remains off unless turned on using the timer.
l
Timer: To temporarily turn the ventilator on, use the up arrow to set the number of minutes you want the
ventilator to run (0-180 minutes). To cancel a temporary setting, touch “Cancel Timed Ventilation”.
2. Touch Save to save your settings.
The display will show whether the ventilator is currently running under “Equipment status”.
41

Lockout During Sleep:
Under the ventilation menu, touch Options”. Select or deselect Disable During Sleep. Touch the back arrow in
upper left of display to return to previous screen.
Indoor Air Quality Monitoring (S1100 and S1200 only)
MCR39705
Indoor Air Quality
Good
The S1100 and S1200 ElitePRO Thermostat monitors for estimated Carbon Dioxide (CO2), Volatile Organic
Compounds (VOCs), and Humidity. A general air quality level is shown under the temperature reading from the
home screen. More detailed readings are shown when Air Quality is selected from the menu. Air Quality is rated
as Great, Good, Fair, Poor and Very Poor. A Poor or Very Poor reading doesn't necessarily mean that the air
quality presents a hazard. The S1100 and S1200 ElitePRO Thermostat is not a substitute for a dedicated CO2
or VOC sensor and only measures the room in which the thermostat is installed. Alerts at the S1100 and S1200
ElitePRO Thermostat thermostat are for awareness only.
NOTE:
Some application environments may regularly generate Air Quality alerts from expected conditions such as
the natural vapors from carpets and other materials in new construction homes.
Carbon Dioxide (CO2)
Carbon dioxide is produced by breathing and from any gas (combustion) appliance such as a gas furnace, gas
stove top and/or oven, etc.
Volatile Organic Compounds (VOCs)
VOCs are chemicals that can come from common household items like paint, cleaners, and furniture. While it's
normal to have some VOCs present in the air, it's good to keep spaces ventilated.
Solutions for poor Indoor Air Quality:
Carbon Dioxide (CO2):
Carbon dioxide is produced by breathing and from any gas (combustion) appliance such as a gas furnace, gas
stove top and/or oven, etc. If CO2 is high, it is most likely indicating insufficient ventilation for the number of
people in the space. Running the exhaust fan while cooking or opening windows can help in some cases,
however if outdoor air quality is poor due to conditions such as forest fires, outdoor barbeques, burning leaves,
42

a window over the vent of a running dryer, etc. then opening a window may be the cause of the poor air quality
indoors. If the indoor CO2 is regularly high, Honeywell Home offers whole home ventilation solutions. In most
cases proper ventilator will greatly reduce the CO2 levels in a home. These products are sold and installed by
HVAC pros. The ElitePRO™ Series Thermostat can control a whole home ventilator.
Volatile Organic Compounds (VOCs):
VOCs are chemicals that can come from common household items like paint, cleaners, and furniture. While it's
normal to have some VOCs present in the air, it's good to keep spaces ventilated. Running the exhaust fan while
cooking and opening a window when outdoor air quality is good will help improve air quality. Honeywell Home
offers whole home ventilation solutions. In most cases proper ventilator will greatly reduce the VOC levels in a
home. These products are sold and installed by HVAC pros. The ElitePRO™ Series Thermostat can control a
whole home ventilator.
Humidity:
The ElitePRO™ Series Thermostat detects the humidity level at the thermostat and/or wireless indoor sensors.
The ElitePRO™ Series Thermostat can control a humidifier or dehumidifier to maintain more comfortable levels
of indoor humidity. These products are sold and installed by HVAC pros.
Disabling Air Quality Monitoring on Thermostat:
The installer may have disabled indoor air quality monitoring during setup.
Disable push notifications and email notifications:
The homeowner can disable push notifications and email notifications through the First Alert app. In the app,
select the thermostat. Select the Gear icon in lower right. Select Alert management. Scroll down to the Carbon
Dioxide and VOC alert options. Adjust those settings as desired.
Waiting for Equipment
Damage can occur if your system’s compressor is
restarted too soon after shutdown. The Built-in
Compressor Protection feature forces the compressor
to wait for a few minutes before restarting. During the
wait time, the display will show the message “Waiting
For Equipment” above the room temperature reading.
When the safe wait time has elapsed, the message
disappears, and the thermostat will indicate a call for
heat.
43

Battery Replacement
Indoor Sensor
Replace batteries in your indoor sensor when a warning appears on the thermostat screen, about 60 days before
batteries are depleted.
When the sensor status light begins flashing red, battery power is critically low and will be depleted within 2–3
weeks. During normal operation, the status light remains off.
To replace the batteries:
l
Remove the sensor from wall plate.
l
Install 2 fresh AAA alkaline batteries. If the status light flashes green, batteries are good; if it flashes red, you
must use fresh batteries.
l
Attach sensor to wall plate.
The sensor will restore communication with the thermostat a few seconds after new batteries are installed.
Outdoor Sensor
Replace the batteries in your outdoor sensor when a warning appears on the thermostat screen, typically about
two months before the batteries are depleted. The outdoor sensor requires 2 fresh AA lithium batteries.
After installing new batteries, the outdoor sensor will restore communication with the wireless network within a
few seconds.

Viewing Dealer information
Check dealer information if you need to contact your installer for maintenance, repairs, or upgrades.
1. Touch MENU.
2. Scroll down and select My Pro.
NOTE:
This menu option will only appear if the contractor had entered this information.
Auto Changeover Operation
Auto changeover is available if the thermostat is configured for at least 1 Heat stage and 1 Cool stage, and the
installing Pro has enabled Auto Changeover.
When configured this way, you can select “Auto” as one of the options under “System mode”.
The differential is the minimum number of degrees the temperature needs to rise or fall before switching from
Heat to Cool while in auto changeover mode. Example: With a differential of 3, if heat and cool were both set for
70, and heat had been used last, the temperature would need to rise at least 3 degrees above the heat set point
46

before the thermostat would turn on cooling. Then it would run cooling down to set point and cycle cooling on
and off to maintain set point. The temperature would then need to drop at least 3 degrees below the cool set
point before heat could come on.
If the AC is used for dehumidification then we enforce an additional temp drop below the over-cooling amount,
prior to switching back to heat.
Em Heat and Auxiliary Heat Operation
Auxiliary Heat:
Auxiliary Heat runs as backup to the heat pump. It runs with the heat pump when:
l
The thermostat is set to Heat mode.
l
The Backup Heat is set to electric .
l
Load conditions determine Backup Heat is needed.
Emergency Heat:
Emergency Heat runs when you manually switch the thermostat to the Em Heat mode. When the thermostat is
in Emergency Heat mode, the heat pump is locked out.
Emergency Heat mode is only available when the thermostat is set to control a heat pump or PTAC plus one or
more Backup Heat stages.
From the home screen touch Mode. You can set the thermostat to Heat, Off, Cool, Emergency Heat, or Auto.
(Auto mode may not be available based on installer settings.)
When the thermostat is set to Em Heat mode, the heat pump is locked out and the Backup Heat is used to
maintain the heat set point.
Adaptive Recovery (Sometimes called “Adaptive Intelligent Recovery”)
Over time, the thermostatlearns how long it takes your system to reach your programmed temperature setting.
The thermostat turns on the heating/cooling system early and assures that the programmed temperature
setting is reached at the programmed time regardless of weather conditions. For example, if the Wake program
period is set to 6:00 am with a heat setting of 70 degrees, the heat will turn on before 6:00 am, so the
temperature is 70 degrees at 6:00 am. The thermostat displays "In Recovery” above the indoor temperature
when it turns the system on early.
Adaptive Recovery calculates the recovery ramp based on how far the room temperature is away from the
temperature setting, previous equipment performance and weather history, allowing the thermostat to start
recovery at the optimal time so it can reach the programmed temperature setting at the programmed time. The
thermostat uses two recovery ramps when set up to control a heat pump system; one ramp for the compressor
and one ramp for the auxiliary heat. Once the room temperature intersects the compressor ramp, the
compressor turns on until the set point is reached. If the room temperature does not rise quickly enough and
intersects the second ramp, the auxiliary heat turns on. It takes about one week for the thermostat to adjust to
weather conditions, equipment performance and construction of the home. If the temperature setting is
reached too early or too late, the ramp is adjusted for the next day's recovery. See figure below:

If you prefer not to use this feature, touch Menu > Preferences > Adaptive Recovery and select Off. Then the
thermostat will not start heating or cooling in advance of the comfort schedule time.
NOTE:
When ElitePRO™ Series Thermostat is set for commercial application it has settings for heat and cool
recovery ramps rather than Adaptive Recovery and these are only adjustable by the installer.
Feels like Temperature
“Feels Like Temperature” is a setting which takes the indoor temperature and relative humidity, as well as
outdoor temperature into account so that you can optimize comfort. For example, when the relative humidity is
very high, 70°F feels much warmer than it does when the relative humidity is very low. For this reason, when
Feels Like Temperature is enabled, the display may show a warmer temperature reading than other thermostats
do when relative humidity is high.
If you prefer not to use this feature, it can be disabled in Menu > Preferences >Display > Feels Like
Temperature.
NOTE: Feels Like Temperature can only be enabled when the thermostat knows the outdoor
temperature from the app, a wireless outdoor sensor, or a wired outdoor sensor.
Remote Setback (Occupancy Setback / Occupancy Sensor)
This optional energy-savings feature is set up by the installer.
The ElitePRO™ Series Thermostat allows you to use Remote Setback (sometimes referred to as Occupancy
sensing or Occupancy setback). This energy-saving feature can be enabled using the internal motion sensor on
select ElitePRO™ Series Thermostats, one or more wireless indoor sensors, or with an occupancy sensor that
opens or closes a dry-contact switch.
During occupied periods, the occupancy sensor tells the thermostat to switch to STANDBY (Setback settings)
when no one is in the room. If someone is in the room, the sensor follows the settings of the Occupied period.
The occupancy sensor is ignored during unoccupied periods. If someone is in the room, the sensor follows the
schedule settings set by the installer or a manual override setting (if not locked out by installer/property
manager).

Multiple doorbells to one thermostat or Multiple thermostats to one doorbell
If pairing multiple First Alert VX1 or Ring Doorbell Cameras in a location with multiple thermostats, individual
doorbells can be linked to individual thermostats.
If a single doorbell is linked to multiple thermostats, both thermostats will receive the notification.
50

If multiple doorbells are linked to a single thermostat and a doorbell is pressed while the thermostat is already
streaming from a different doorbell, the second doorbell will be ignored until the initial stream ends.
There is no maximum number of pairings. The limiting factor is network bandwidth.

FAQ's
WiFi connection questions
See "WiFi Setup and Troubleshooting" on page13.
Software and security questions
Q: How can I be sure my thermostat is running the most up-to-date firmware?
A: When your thermostat is connected to WiFi, it will automatically receive over-the-air firmware updates from
the First Alert App. These firmware updates contain things such as new features as well as security upgrades.
Keep your thermostat connected to WiFi to ensure it receives these updates.
Q: How can I prevent a cybercriminal from making unauthorized changes to my thermostat?
A: If a cybercriminal gains access to your First Alert app, they can tamper with the settings of the products on
that app, or remove those products from your account and add them to a different account. Make sure you
select a password that meets the recommendations for complexity and save it in a secure location that others
cannot access.
Other questions
Q: How can I remove the ElitePRO™ Series Thermostat from my WiFi network and App?
A: If you want to replace your ElitePRO™ Series Thermostat, or if you’re moving out of your home and leaving the
thermostat behind, you’ll first want to clear out the personal settings that are stored on the thermostat. (Even
when disconnected from power, the thermostat will keep your settings and home router information in memory.)
We recommend resetting the thermostat’s WiFi and Matter
®
settings (if previously connected).
Q: Is there a motion sensor in the thermostat?
A: The ElitePRO™ Series Thermostats have an on-board motion sensor in the thermostat. Additionally up to 20
C7189R3010 wireless indoor temperature, humidity, and motion sensors can be used with any of the ElitePRO™
Series Thermostats.
Q: What happens if “Active rooms” is used and no motion is detected in any of the rooms with
sensors?
A: If the thermostat is set to control by active rooms, and no motion is detected, the sensor in the thermostat is
used and the remote sensors are excluded. Most people schedule the sleep period to use “Selected sensors”
rather than “active sensors” and choose the bedrooms for the sleep schedule.
The ElitePRO™ Series Thermostats have a setting for "Fallback sensor" which would be used rather than the
thermostat if selected.
Q: When using active rooms, how long are those rooms considered "Active" after motion has last been
detected?
A: The sensor has an occupancy algorithm based on how many motion events it sees within a certain timeframe.
This was set up so that if someone briefly walks through a room, the sensor will tell the thermostat that the
room is “occupied” for 10 minutes. If someone is in a room longer, then the timeout will be increased
automatically.
Sensors communicate directly with the thermostat via Honeywell Home Redlink 3.0 technology. After sensing
motion, the communication should take less than 3 seconds to assign the room priority, depending on battery
and signal strength.
Q: How do the wireless indoor sensors detects motion.
A: The sensors use a Passive Infrared Sensor (PIR) detector.
52

Q: How does motion-based priority work with multiple people in the house?
A: If the thermostat’s priority is set to ‘Active Rooms’, then any room that detects motion will become prioritized.
The average of those rooms’ temperatures will be monitored so that the thermostat can adjust to your preferred
temperature setpoint. If one of the sensors no longer detects people in that room, that sensor will adjust after a
period of time, using the algorithm based on motion events that it sees within a certain time frame.
Q: What’s the range of detection on the motion sensor?
A: There are many factors that can affect this (height, body size, layers of clothing, temperature of clothing,
angle, etc.). The typical range of our sensor is up to 20 feet.
Q: Are the ElitePRO™ Series ThermostatsUL and ULC listed or CSA listed?
A: UL, ULC, & CSA ratings are not required for low-voltage rated controls such as the ElitePRO™ Series
Thermostats. UL rating is required for devices supplied by 50 volts or higher.
Q: What does "Warming Sen" mean on the thermostat display?
A: This message indicates that the thermostat is warming up its Indoor Air Quality (IAQ) sensor. It usually
appears briefly after the thermostat is powered on.
Q: What should I do if my thermostat indicates poor indoor air quality?
A: See "Indoor Air Quality Monitoring (S1100 and S1200 only)" on page42 for solutions.
Q: What does it mean when my thermostat shows “Calculating” in the Indoor Air Quality screen?
A: The thermostat will display “calculating” after initial installation or after a power-up to ensure the sensors are
getting an accurate sampling of the air before showing the VOCs or estimated Carbon Dioxide. This may take
several minutes.
Q: How can I keep the display from lighting up?
A: There are several options that control the display brightness and when the screen lights up. In some cases,
you may not want the display to light up when motion is detected (for example, if thermostat is installed in an
infant’s bedroom). Menu > Preferences > Display has options including:
l
Idle screen behavior: Determines whether the display transitions to the active screen when motion is
detected or when the screen is tapped.
l
Screen brightness: Allows customer to adjust the brightness setting for both active and idle screens.
l
App change behavior: Lets you choose whether the display transitions to the active screen when a change is
made through the app, or remains on the idle screen.
Q: Why does the display go to the Honeywell Home startup screen?
A: It is normal that the thermostat will go to the startup screen where it shows “Honeywell Home” and then
returns to the idle screen after a short delay if there has been a power outage or if there has been an over-the-
air firmware update. Either of these should be a very infrequent occurrence. If you notice this is happening
regularly, there may be an issue with your equipment. Example: a limit may be tripping due to poor airflow.
If the issue happens regularly, we would recommend replacing the furnace filter and having an HVAC pro
service the unit if the issue persists.
NOTE:
A thermostat that uses batteries, or does not have a premium display, may have been masking this type of
system issue, however if a limit is regularly cutting power to the thermostat your system will likely have
reduced performance and could be susceptible to damage.
53

Q: What happens if there is a power loss to the thermostat?
A: During a power loss the HVAC equipment cannot run.
Once power is restored the thermostat goes through a power up cycle and will initially show "Honeywell Home"
on the screen.
l
If the thermostat is used with any Redlink 3.0 accessories, it will re-establish communication within 6
minutes.
l
If the thermostat had been connected to a WiFi network and the app, it will re-establish connection and
update the time/date.
l
If the thermostat was not connected to a WiFi network and registered to the app, the time/date will need to be
reset for the thermostat to follow the program schedule.
All schedule settings are permanently stored during a power outage, however, if scheduling had been used, the
thermostat will maintain 72F in heat and 78F in cool mode until the time/date has been set.
If the thermostat had been used in a permanent hold, that setting is also permanently stored during a power
outage.
The thermostat will be in the same mode it had been in when power was lost (Example: heat, off, cool).
54

Troubleshooting and Support
If you have difficulty with your thermostat, please try the following suggestions. Most problems can be corrected
quickly and easily.
Display Behavior Is Not As Expected
Display is blank:
l
Check circuit breaker and reset if necessary.
l
Make sure power switch for heating & cooling system is on.
l
Make sure furnace door is closed securely.
l
Make sure the C wire is connected.
Cannot change temperature setpoint:
l
Verify the thermostat is set to the correct mode. Touch Mode to change mode setting.
l
If the display indicates “Setting locked” when you touch the up or down arrow, you can unlock the screen by
selecting Menu > Screen lock.
l
The thermostat may be preventing you from changing the set-point above or below a certain setting because
of minimum and maximum settings. Menu > Preferences > Temperature limits.
l
Default minimum and maximum settings:
o
Heat: 40°F to 90°F (4.5°C to 32.0°C)
o
Cool: 50°F to 99°F (10.0°C to 37.0°C)
Weather menu isn’t displayed:
This menu is only shown when the thermostat is connected to WiFi and the app. If WiFi connection is lost, the
thermostat will not show that option until connection is restored.
Display doesn't show indoor humidity:
The installer may have set the thermostat to not display humidity.
Display temperature is inaccurate (reads too high or low)
There are different reasons that the room temperature reading on the thermostat may be reading higher or
lower than expected.
l
“Feels Like Temperature” is a setting that can make the indoor temperature reading show a few degrees
warmer when relative humidity is high. See "Feels like Temperature" on page48.
l
Indoor display offsets can be set to make the display read up to 3 degrees higher or lower than the sensor
reading or +/- 12% RH from the humidity sensor reading. See "Indoor Display Offsets" on page26.
l
If one or more wireless sensors is used, the thermostat can be set to measure temperature at the thermostat,
a wireless sensor, or an average reading. See "Priority" on page29.
l
If a sensor is wired to the S terminals on UWP, feedback on that sensor can cause display accuracy issues.
Even if the thermostat is set to a wired outdoor sensor, if that sensor is wired in parallel to another thermostat
or zone panel or getting feedback some other way, this can drastically affect the indoor temperature reading.
Menu options are not shown
When Menu is selected, the display shows menu options and allows the user to scroll left or right to see
additional options. Some options may not be shown if the thermostat is not set to support those settings such
55

as humidification. If the display is set for a lockout, many of the menu options are not shown. Select MENU >
SCREEN LOCK to view lockout status. The lockout status should only be changed by the thermostat owner and
there may be an option to require a password in order to unlock the screen.
Heating or Cooling Issues
Heat runs with thermostat in cool or off mode:
Does the display show “Freeze Protection active”? If so, the installer set the thermostat for a freeze protection
temperature that maintains a minimum temperature even when the thermostat is set to off or cool. This feature
will generate an alert message if the temperature drops below the freeze protection setting.
In addition to the Freeze protection setting, when used for an radiant floor heat system, there are settings for
minimum and maximum floor temperature.
If it is still not clear why heat is running, turn off power at the heating equipment and call the Pro installer to
troubleshoot the issue.
Heat doesn’t come on:
When in the heat or emergency heat mode and not calling for heat, the display shows “heat to”.
When calling for heat or emergency heat the display shows “heating to”.
If display is showing “WAITING FOR EQUIPMENT” above the room temperature it is in a delay mode to protect
the equipment. If the delay lasts longer than 5 minutes, see "WAITING FOR EQUIPMENT stuck in display" on the
next page.
If display is not showing “WAITING FOR EQUIPMENT”, verify the thermostat is set to Heat, Em Heat, or Auto
mode and verify that the heat setpoint is above room temperature. Does the display indicate “Heating to” (rather
than "heat to") above the set point?
If “HEATING TO” is displayed, and heat does not come on after a short delay, have the installer verify wiring
connections and R/Rc slider switch on UWP are good.
If “HEAT TO” (rather than "HEATING TO") is displayed above the setpoint, but heat set point is above room
temperature, go to EQUIPMENT STATUS and see if any reason is given for why heat is not running.
Check for any active alerts. The ElitePRO® Series Thermostat can be set to lock out heating during active alerts.
A custom Dry Contact Alert set to lock out cooling could have been snoozed (or set to not display alert message
by installer) but equipment status would show the cooling as “Idle (Dry contact lockout)”.
Cooling doesn’t come on:
When in the cool mode and not calling for cooling, the display shows “cool to”.
When calling for cooling the display shows “cooling to”.
If display is showing “WAITING FOR EQUIPMENT” above the room temperature it is in a delay mode to protect
the equipment. If the delay lasts longer than 5 minutes, see "WAITING FOR EQUIPMENT stuck in display" on the
next page.
If display is not showing “WAITING FOR EQUIPMENT”, verify the thermostat is set to cool, or Auto mode and
verify that the cool setpoint is below room temperature. Does the display indicate “cooling to” (rather than "cool
to") above the set point?
If “COOLING TO” is displayed, and heat does not come on after a short delay, verify the wire connections, R/Rc
slider jumper on UWP (or R, Rh, and Rc jumpers if an EIM is used). If those variables check out, your HVAC
contractor can call Tech Support to verify configuration and for further troubleshooting.
If “COOL TO” (rather than "COOLING TO") is displayed above the setpoint, but cool set point is below room
temperature, go to EQUIPMENT STATUS and see if any reason is given for why cooling is not running.
56

Check for any active alerts. The ElitePRO® Series Thermostat can be set to lock out heating during active alerts.
A custom Dry Contact Alert set to lock out cooling could have been snoozed (or set to not display alert message
by installer) but equipment status would show the cooling as “Idle (Dry contact lockout)”.
WAITING FOR EQUIPMENT stuck in display
If display shows “WAITING FOR EQUIPMENT” then the thermostat is holding off running the heating or cooling
to prevent short cycling or because of a lockout condition. The short cycling delay should last 5 minutes at
most, but an alert lockout will keep that equipment locked out until the alert condition is resolved. The short
cycling delay most commonly would occur on start up, after a power loss, or if someone adjust setpoint within 5
minutes of equipment shutting off.
If you time this and it shows "WAITING FOR EQUIPMENT" for longer than 5 minutes.
l
See if there are any active alerts. The ElitePRO® Series Thermostat can be set to lock out the heat during
certain alerts. A custom Dry Contact Alert set to lock out heat and/or cooling could have been snoozed (or set
to not display alert message by installer). In some cases, the equipment status would indicate why the heat or
cool is off (Example: it may show “Idle (Dry contact lockout)”.
l
It is possible there is an intermittently power loss to the thermostat. As a test the installer could remove all
wires besides R and C from UWP (or EIM if the ElitePRO® Series Thermostat is linked to an EIM) and then test
the heat or cooling. If the thermostat then indicates a call for heat or cooling within 5 minutes, a shorted wire
or high equipment draw could be interrupting power to the thermostat momentarily at the start of a heat or
cooling call.
Cooling runs below set point:
Verify the cooling is running while cool set point is above the room temperature reading on the display. If so,
verify the thermostat is deliberately running cooling. When doing so, the display shows “Cooling to” (rather than
“COOL TO”). Also, menu equipment status will show if the thermostat is trying to run cooling or not.
l
If the display shows “Cooling to” and a setting that is above the room temperature reading it is likely the
ElitePRO™ Series Thermostat has been set to over-cool when humidity is high. If that display shows a status
of “DEHUMIDIFYING” select “OPTIONS” and deselect “USE DEHUMIDIFICATION”. Then go back to the home
screen and see if the cool call ends. The ElitePRO™ Series Thermostat can run the cooling up to 3 degrees
below the cool set point if configured to use the air conditioner for dehumidification.
See "Indoor Air Quality Control and Monitoring" on page38. If over-cooling is not desired, go to the
dehumidification menu and turn dehumidification off.
l
If display shows “COOL TO” over setpoint, and the cooling is running, something is wrong. Turn off the power
to the cooling equipment and call a professional for assistance.
Heat runs when room temperature reading is above the heat setpoint:
l
If the thermostat is not in heat mode, see “Heat runs with thermostat in cool or off mode”.
l
If the thermostat is in heat or emergency heat mode, verify whether the display indicates a call for heat.
If display shows “HEAT TO” over setpoint, the heat should not be running.
If the display shows “HEATING TO” over setpoint, the thermostat is trying to run the heating.
Display shows HEAT TO and heat is running.
The thermostat is not trying to run the heating at this time. If display shows “HEAT TO” over setpoint, and the
heat is running, something is wrong. Turn off the power to the heating equipment and call a professional for
assistance.
Display shows HEATING TO and heat is running.
The thermostat is trying to run the heating at this time. It is unusual that the thermostat would run heat if the
room temperature reading is above the setpoint in thermostat display. Check equipment status.
57

Does the display indicate “Freeze Protection Active” above the room temperature?
In addition to the Freeze protection setting, when used for an radiant floor heat system, there are settings for
minimum and maximum floor temperature.
If it is still not clear why heat is running, turn off power at the heating equipment and call the Pro installer to
troubleshoot the issue.
Fan Issues
Fan will not run when expected
If the thermostat is set to control a heat-only system such as a boiler, there will not be a fan setting. Menu >
Equipment Status will show the fan state.
For forced air heating or cooling, check equipment status. This will show the fan state. If it says “Idle (Fan
Lockout)”, then the installer configured the thermostat to lock out fan at the end of a call for cooling for
anywhere from 5 to 90 minutes. This is set up for some homes in very humid regions where running the fan at
the end of a cool call can blow air over a wet coil and re-introduce humid air back into the space.
The ElitePRO™ Series Thermostat can have the fan set to on, auto, or circ for each schedule period. For some
systems, there may alternately be fan settings of low, medium, and high. See "Fan Scheduling" on page24.
Fan is running unexpectedly
l
The thermostat have different settings that might have turned on the fan. Check Menu > Equipment Status
to see what the thermostat indicates it is running.
l
The thermostat could be set to run the fan with a call for ventilation, humidification, or dehumidification.
l
The thermostat will also run the fan with a call for cooling and in forced air heat systems the fan will also run
with a call for heat (but this may or may not be controlled by the thermostat depending on the system type
settings).
l
Additionally, the thermostat has a “TEMPERATURE BALANCING” option to run the fan to average hot spots
and cool spots if a remote sensor is used. This would have been configured by the installer in the ISU. To see
if this is being used, go to menu and look for TEMPERATURE BALANCING. If that option appears, select it and
see if it is currently active.
l
The thermostat can have the fan set to on, auto, or circ for each schedule period. For some systems, there
may alternately be fan settings of low, medium, and high. See "Fan Scheduling" on page24.
l
If the thermostat doesn’t indicate the fan is on under the EQUIPMENT STATUS menu, it is possible something
else in the system is controlling the fan such as a separate control for a humidifier, dehumidifier or ventilator.
Fan mode changes by itself
See the "Fan is running unexpectedly" above or "Fan will not run when expected" above.
