THERMOSTAT QUICK REFERENCE 
Before you begin programming your thermostat, you should be 
familiar with its features and with the display and the location 
and operation of the thermostat buttons and switches (see fig. 
3). Your thermostat consists of two parts: the thermostat cover 
and the base. To remove the cover, pull it straight out from the 
base. To replace the cover, line up the cover with the base and 
press until the cover snaps onto the base.
The Thermostat Buttons and Switches
1   Raises temperature setting.
2   Lowers temperature setting.
3   SYSTEM switch (COOL, OFF, HEAT, EMER).
4   FAN switch (ON, AUTO).
The Display
5   Indicates setpoint temperature. This is blank when system 
switch  is  in  the  OFF  position.  Setpoint  temperature  is 
displayed (flashing) if the thermostat is in lockout mode to 
prevent the compressor from cycling too quickly.
6   “AUX” indicates auxiliary stage is operating.
7   “Save” indicates the Cool Savings feature is enabled in 
the configuration menu. 
“Save” (flashing) indicates Cool 
Savings feature is active.
8   Flame icon ( ) is displayed when the SYSTEM switch is 
in the HEAT position. 
Flame icon ( ) is displayed flashing 
when thermostat is calling for heat. 
Snowflake icon (
) is displayed (non-flashing) when the SYSTEM switch is 
in the COOL position. 
Snowflake icon ( ) is displayed 
(flashing) if the thermostat is calling for cool.
9   Displays current temperature. 
10   “Service”  indicates  a  diagnostic  fault  in  the  heating/
cooling  system.  It  does  not  indicate  a  fault  in  the 
thermostat.
