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. 5). 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

1Raises temperature setting.

2Lowers temperature setting.

3TIME button.

4SYSTEM switch (COOL, OFF, HEAT, EMER).

5PRGM (program) button.

6FAN switch (ON, AUTO).

7RUN/HOLD (program) button.

13Displays current temperature.

14“Service” indicates a diagnostic fault in the heating/cooling system. It does not indicate a fault in the thermostat.

15“EMER” is displayed flashing when the system switch is in EMER position, bypassing the Heat Pump.

16“Change Filter” is displayed when the system has run for the programmed filter time period as a reminder to change or clean your air filter.

9Indicates 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.

10“AUX” indicates auxiliary stage is operating.

11“Save” indicates the Cool Savings feature is enabled in the configuration menu. “Save” (flashing) indicates Cool Savings feature is active.

12Flame 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 () and is displayed (flashing) if the thermostat is calling for cool.
