Additional Operating Features
Auto Changeover Mode
When Auto Changeover mode is enabled and selected, the system
automatically switches between heating and cooling when the
room temperature meets the current heating or cooling set points.
To operate properly, the thermostat maintains a forced separation
between the heating and cooling setpoints to prevent these systems
from working against each other. If a setting is made in either
heating or cooling which violates the forced separation, the opposite
mode will adjust up or down accordingly to maintain the current
forced separation.
Select Auto Changeover Mode by pressing the SYSTEM button until AUTO HEAT or AUTO COOL appears in the
display. Whichever system was running last will remain in the display until the opposite system runs.
Adaptive Recovery Mode (ARM
TM
)
If enabled, Adaptive Recovery Mode attempts to achieve your desired heating or cooling temperature at the time
you have set in your current program schedule, after a setback period. For example, if you set your heat down to
62° at night and have a set point of 70° scheduled for 7:00 AM, the thermostat may turn on your heating system
early in order achieve a temperature of 70° by 7:00 AM.
This feature does not operate when the thermostat is in HOLD mode; if the program is temporarily overridden or
if emergency heat is selected on a multistage heat pump system.
User Manual 30

Circulating Fan Mode
Circulating Fan Mode is selected by touching the FAN button until
CIRC appears in the display. When in CIRC mode the fan operates
as required by the heating and cooling system (just like AUTO mode).
When heating or cooling is not active, fan will run as needed to
ensure a 35% minimum run time.
Programmable Fan Mode
Programmable Fan Mode allows the user to run the system fan in
the AUTO, ON or CIRC mode during a selected program event.
This selection is made during the programming process
(See “Setting Your Program Schedule” in section 3).
Programmable Fan is selected by pressing the FAN button until
FAN PROG appears in the display. It is not available if the
thermostat was configured to be Non-Programmable, however
it will still function if the thermostat is placed into HOLD mode.
Compressor Protection
This thermostat includes an automatic compressor protection delay to avoid potential damage to your system
from short cycling. This feature activates a short delay after turning off the system compressor.
Additionally, for multistage heat pump systems, this thermostat provides cold weather compressor protection by
locking out the compressor stage(s) of heating for a period of time after a power outage greater than 60 minutes.
During this lockout period, the thermostat will operate the auxiliary stage of heating.
31 User Manual

Outdoor
Remote Sensing
Outdoor remote sensing is achieved by installing a Braeburn
®
remote outdoor sensor (model 5490 or 7490).
When properly connected, the current outdoor temperature can be
viewed in the left side of the display. An outdoor sensor can also
used in certain Heat Pump applications for heating and
cooling balance points.
Indoor
Remote Sensing
Indoor remote sensing is achieved by installing a Braeburn
remote indoor sensor (model 5390 or 7390).
If
a Braeburn indoor remote sensor was installed and properly configured, the thermostat will sense temperature
at a remote location or an average of a remote location and the thermostat location.
NOTE: For instructions on connecting wireless sensors, please see the Wireless Setup Guide.
