Replacing Existing Thermostat
Most thermostats have three parts:
• The cover, which may snap or hinge over the existing thermostat.
• The electronics or body, which controls the existing system.
• The sub-base, where the wires attach through the wall to the existing system.
1. Always turn off power to the air conditioning and heating system prior to
removing existing thermostat.
2. Carefully remove the cover and electronics body from the old thermostat
sub-base. Depending on the brand, these parts may pull off or need to be
unscrewed. The old sub-base should remain wired and on the wall until steps
4 and 5.
3. Label every old wire with the letter of the connection to which the wire is
attached. Example letters are R, M, and Y etc. Depending on the brand of the
old thermostat, your letters may be different.
4. After labeling the old wires, loosen each connection and remove them from old
sub-base. Secure the wires to prevent them from slipping into the hole in the wall.
5. Remove the old sub-base from the wall, again being careful that the wires do
not slip into the hole in the wall.
6. Use the chart below to determine the new thermostat connections. As an
example, if the old thermostat had a G or F connection, it goes to G on the new
thermostat. Using a pencil and the chart below, circle the letter of each wire
removed from the old thermostat.

Installing Your New Thermostat
NOTE: When installing this thermostat in a new location, following a few simple
guidelines and the applicable building codes will give the best results. Install the
thermostat in a location that provides good airflow by avoiding areas behind doors,
near corners, air vents, direct sunlight or heat generating devices. The wiring must
conform to all building codes and ordinances as required by local and national
code authorities having jurisdiction for this installation.
1. Always turn off the power to the air conditioning and heating system prior to
installing this thermostat.
2. Locate the release latch on the bottom (not the back) of the thermostat. Press
the release latch in and separate the body from the sub-base of the thermostat.
3. Set the thermostat electronics and cover down on a clean surface. Place the
sub-base on the wall in the desired location.
4. Using the slotted mounting holes in the sub-base, mark the placement of the
mounting holes through the slots and onto the wall. Insure the wires come out
of the wall into the center hole of the sub-base.
5. After verifying the drill will not damage items in the wall, use a 3/16 drill to
create the mounting holes. Gently tap the supplied plastic anchors into the holes
in the wall.
6. Place the thermostat sub-base against the wall in the desired location. Ensure
the thermostat is level, the wires are inserted in the opening, and the mounting
holes are aligned with the slots on the sub-base.
7. Fasten sub-base to wall using the supplied screws into the plastic wall anchors.
8. Connect wires to the quick wiring terminal blocks. Use the wiring diagram chart
to insure the old and new connections are correct.
9. To prevent electrical shorts and potential damage to the thermostat, make sure
all wire connections are secure and not touching each other.
10. Turn the thermostat body over, exposing the rear view of the circuit board.
11. Locate the internal ˚F / ˚C switch on the circuit board. Using your fingers, flip
the switch toward the preferred temperature ˚F / ˚C scale.
12. Locate the internal fan option switch, HG (Gas) / HE (Elec) on the circuit board.
This switch controls the heating system fan delay. Select gas for gas or oil fired
systems. This will allow the furnace to run for a few seconds before starting
the fan. Select electric for systems with electric furnace elements that require
the fan to come on immediately. Using your finger, flip the switch toward the
HG (Gas) or HE (Elec).
13. Locate the internal NORM HP switch on the circuit board. This switch configures
the thermostat for normal (NORM) heating and cooling systems or heat pump
(HP) systems. Using your fingers, flip the switch toward the NORM or HP.
14. Locate the internal programming switch on the circuit board. This switch
configures the programming mode for either 5-2 DAY (weekday-weekend), or
full 7 DAY programming. Using your finger, gently flip the switch toward the
programming option that best suits your schedule.
15. Ensure the cover is still installed on the thermostat body, and install the unit
onto the sub-base. To do so, use the mounting tabs on the top of the sub-base
as a guide hinge, and close up the thermostat case by pivoting the body and
cover closed. The latch on the bottom of the thermostat will click when the case
is properly closed.

Locking the Keypad
To prevent accidental or undesired
adjustment of the thermostat, the Keypad
Lockout feature disables the operation of
the keypad except for the backlight key. In
order to lock the keypad, press and hold
both the and buttons together at the
same time for 5 seconds. The LOCK
segment in the display will flash once per second, and then appear continuously

the and buttons together at the same time for 1 second. The LOCK segment
will disappear and the keypad will become unlocked.
Adaptive Recovery Mode (ARM™) (see section 4)
In order to maximize comfort and energy efficiency, this thermostat is equipped
with an Adaptive Recovery Mode (ARM™). This feature minimizes the amount of
time required by heating or cooling system to reach the new set point, after a
setback period is completed, and assures your desired temperature is achieved
at your set program times.
This feature activates when recovering room temperature from setback programs
to comfort programs, so it will only take place when the current (heating)
program set point temperature is lower than the upcoming program set point
temperature, or the current (cooling) program set point temperature is higher
than the upcoming program set point temperature.
During ARM™, room temperature is recovered gradually by turning on the
heating or cooling before the end of the setback period. The set point temperature
is changed to that of the upcoming comfort program temperature. The start time
of recovery is based on the difference between the current room temperature and
the upcoming comfort program set point temperature. The recovery to the
upcoming set point starts 10 to 15 minutes before the upcoming set point time
for each degree of temperature change required, up to a maximum of 2 hours in
the HEAT mode, 3 hours in the COOL mode.
ARM™ does not operate when the unit is in HOLD mode, or if the program is
temporarily overridden.

Circulating Fan Mode–Fan Operation
AUTO: Fan operates as required by heating or cooling system.
: When heating or cooling is not active, fan will run as needed to ensure
a 35% minimum run time.
ON: Fan will run at all times.
®
Compressor Protection
This thermostat includes an automatic compressor protection feature to avoid
potential damage to the cooling system from short cycling. This thermostat
automatically provides a 5-minute delay after turning off the cooling system
output to protect the compressor. This protection is also present in the heat mode
of operation on single stage heat pump systems to protect the compressor.
NOTE: The installer can reset the thermostat and bypass the compressor
protection features by pressing the RESET button. This will erase all entered
programs, current time of day, day of week and other user settings and should
only be used during installation for testing purposes or to reset a thermostat
to regain normal operation. This will return all thermostat settings to their
default values.
Low Battery Detection
This thermostat requires two (2)
new,
properly installed “AA” Alkaline batteries
to maintain the system clock and to provide
proper thermostat power when 24 volt AC
power fails or is not connected to the
thermostat. When the batteries start to become
too weak to provide proper operation, the
thermostat will begin to display a low battery indicator.
The low battery indicator is provided to inform the user when the batteries
require immediate attention. We recommend replacing the batteries as soon
as the low battery indicator appears. If the batteries are not replaced after
the low battery indicator first appears, the thermostat may not provide
proper heating or cooling system operation.
Even if the low battery indicator does not appear, the batteries should be replaced
at least once a year, or if you plan on leaving the premises for over a month.
This thermostat can be powered from 24 volts AC or battery power. To determine
if 24 volt AC power is connected to the thermostat, refer to the installation and
wiring diagram section. If you cannot determine how this thermostat is powered,
call a professional service technician to determine the type of installation and the
proper operation of your system.
Resetting the Thermostat
The Reset feature allows the user to completely reset the thermostat to register
new manual switch settings. To erase all entered programs, current time of day,
day of week and other user settings, gently press the RESET button using a paper
clip or a small pencil tip. This will return all thermostat settings to their default
values and register all new manual switch settings for proper operation.
Non-Volatile Memory
In the event of a power failure, the Non-Volatile Memory feature allows all
settings to be recovered, eliminating the need to reset temperature and
differential settings. When AC power is restored after an outage, all settings are
retrieved from memory and reinstated.
Status Indicators
