OPERATION FEATURES
Compressor Protection

This thermostat includes an automatic compressor protection feature to avoid potential damage
to the compressor from short cycling. This thermostat automatically provides a 5-minute delay
after turning off the cooling or heating system output to protect the compressor.

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.
Low Battery Detection and Replacement
5.5
This thermostat requires two (2) properly installed "AA"
alkaline batteries to provide back-up power for the
thermostat. The thermostat must have 24 Volt AC
power present for proper system operation and control.
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 back-up power.
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 the system clock in the event of a power outage.
Replacing the Batteries
1. Open the 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.
Adaptive Recovery Mode (ARM™)
5.6
This thermostat is equipped with a special feature to maximize your energy savings by
utilizing the most effective source of heating or cooling to meet your program needs during
recovery from setback (or setup) temperatures. Our Adaptive Recovery Mode (ARM™)
feature is designed to automatically calculate when to turn your first stage of your multi
stage heating or cooling system to meet your upcoming comfort setpoint temperature
setting. While in normal operating mode, this feature will start calculating the start time for
your first stage two hours prior to the upcoming comfort setpoint temperature. During this
two hour time period it will monitor performance and control your system staging
requirements. The second (auxiliary) stage of heating will be available during this 2-hour
period if required to meet extraordinary heating requirements.
