SETTINGS
Setting SYSTEM and FAN Switches
System and fan settings are controlled by using SYSTEM and FAN switches located on the bottom of the thermostat case. First set the SYSTEM switch:
- Cool: Normal setting for months when your home needs cooling (air conditioning). The digital display shows a snowflake
when cooling is on. - Off: Both heating and cooling are off.
- Heat: Normal setting for months when your home needs heating. The digital display shows a flame
when the heating is on. - Em. Ht.: Switch to this setting when your home needs heat, but your equipment needs servicing or is not working properly. In this mode, the thermostat controls only the backup heat. The heat pump is off.
Then set the FAN switch:
- Auto: Normal setting for most homes. Some systems may delay the fan from turning on and off with the equipment.
- On: The fan runs continuously. Use for improved air circulation and air quality
Emergency Heat
The Emergency Heat feature allows you to “turn on” the electric heat section of the system by moving the system switch to the Em. Ht. position. The indicator 
flashes and points to Em Ht when the system is in
emergency heat mode. The indicator may also point to Aux Ht if the system calls for additional backup heating.
Auxiliary Heat
The auxiliary heaters assist the heat pump under normal conditions when a low outdoor temperature occurs. The indicator points to Aux Ht when the auxiliary heating equipment operates.
Displaying Temperature Setting
NOTE: Your temperature setting can be set anywhere from 50° to 99°F (10° to 37°C).
The temperature setting and the room temperature are displayed separately. The indicator points to Set when the temperature setting displays, and to Room when the room temperature displays. The thermostat displays room temperature unless or is pressed.
