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.
NOTE:
Resetting the thermostat by pressing the RESET button will erase all entered
programs, current time of day, day of week and other user settings. This will return all
thermostat settings to their default values. Changing ˚F / ˚C temperature scale default should
be done prior to installation and before any programming to avoid loss during reset step.
5.9 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.
5.8 Low Temperature "Freeze" Protection
While the thermostat is in the HEAT mode of operation, on standard heating (non-heat
pump) applications, the thermostat will mechanically initiate a call for heat if the room
temperature drops to less than 41˚F (5˚ C). The system selector switch must be in the
HEAT position for this feature to be active. This feature will allow the thermostat to
initiate a call for heat on standard heating (non-heat pump) applications, to provide a
minimum amount of heat, even if the batteries are dead or missing. This feature is only
active on standard heating (non-heat pump) applications and is not available on single
stage heat pump applications.
5.10 Low Battery Detection and Replacement
This thermostat requires two (2) properly installed "AA" alkaline batteries to provide power
for the thermostat to properly control the system operation. This thermostat is equipped
with a low battery detection feature that constantly
monitors the batteries during normal operating mode
to determine whether they have sufficient power to
provide proper operation. When this feature determines
that the battery status is low, a low battery indicator
will appear in the display. It is recommended that the
batteries be replaced immediately to maintain system
operation and program settings.

Replacing the Batteries
1. Open the front thermostat cover and locate the battery compartment door.
2. Gently remove the two "AA" alkaline batteries located in the battery compartment.
3. Install two new "AA" alkaline batteries into battery compartment. Make sure to match
the positive (+) ends of the batteries with the positive (+) terminals located in the
battery compartment.
4. Close battery compartment and verify that the low battery indicator does not appear in
the display.
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.
5.11 Resetting the Thermostat
5.6 Adaptive Recovery Mode (ARM™)
5.7 Recirculating Fan Mode (see section 4.3 )
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
the heating or cooling system to reach the new setpoint, 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 setpoint temperature
is lower than the upcoming program setpoint temperature, or the current (cooling) program
setpoint temperature is higher than the upcoming program setpoint temperature.
During ARM™, room temperature is recovered gradually by turning on the heating or cooling
before the end of the set back period. The setpoint 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
setpoint temperature. The recovery to the upcoming setpoint starts 10 minutes before the
upcoming setpoint time for each degree of temperature change required, up to a maximum
of 2 hours.
ARM™ does not operate when the unit is in the HOLD mode, or if the program is
temporarily overridden.
The Recirculating Fan Mode provides more even temperature distribution and improves
indoor air quality by circulating air through the furnace filtration system more often.
The Recirculating Fan Mode can be selected by moving the fan switch to the recirculate
position(
®
). If no call for heating or cooling occurs within the fan off cycle set in
section 4.3, the fan will run for 12 minutes. The highest setting, 120 minutes (factory
default), will run the fan least often–9% minimum run time. The lowest setting, 40
minutes, will run the fan most often–23% minimum run time. During any call for heating
or cooling, fan control returns to the AUTO mode. The Recirculating Fan feature is
available in the HEAT, OFF, or COOL mode.
