OPERATION FEATURES
3.12 Compressor Protection and AC Power Monitor
This thermostat includes an automatic compressor protection feature to avoid potential damage to the cooling
system from short cycling. This thermostat automatically provides a delay, set during Installer Setup, see section
4.2 of the Installer Guide, 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. The user will have to reprogram all of
the erased settings.
If enabled during Installer Setup, see section 4.2 of the Installer Guide, this thermostat also provides cold weather
compressor protection by locking out the compressor stage (1st Stage) of heating for a period of time after a power
outage greater than 60 minutes. The lockout period is one hour less than the outage time, up to a maximum of 12
hours. During that period of time, the auxiliary heat stage will still be available to maintain the setpoint temperature.
The compressor lockout can be manually overridden at any time by changing the system mode to OFF momentarily,
then back to HEAT.
NOTE:
This feature only applies to 2 Stage Heat Pump Systems.
During a power loss, the thermostat will display an outage warning,
if enabled during Installer Setup, see section 4.2 of the Installer
Guide. The system clock will continue to run, and all settings will be
maintained until the outage period is over.

OPERATION FEATURES
3.13 Low Battery Detection and Replacement
This thermostat requires two (2) properly installed "AA" Alkaline batteries to maintain the system clock and to
provide power for the thermostat if 24 volt AC power is not connected to the terminal block.
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 / or clock settings.
Replacing the Batteries
1. Open the front 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.
