OPERATION

The Mode button selects the operating mode of the ther- mostat. If OFF is selected, the thermostat will not enter Heat- ing or Cooling mode. If HEAT is selected, the thermostat will only enter Heating mode (if the room temperature is below the heating set point). If COOL is selected, the ther- mostat will only enter Cooling mode (if the room tempera- ture is above the cooling set point). If AUTO is selected, the thermostat will enter Heating or Cooling mode based on the room temperature and the heating and cooling set points. If PROGRAM ON is selected, the stored schedule is enabled and the thermostat will follow the Occupied and Unoccu- pied schedules stored in its memory.

Auto-Changeover Ð When the thermostat mode is set to AUTO, the thermostat will provide automatic changeover from Heating to Cooling mode and Cooling to Heating mode when required. The thermostat will automatically switch to maintain the desired temperature setting. The thermostat does not need to be manually changed from heating to cooling or cooling to heating operation.

Two-Stage Operation Ð The second stage of heat or cool is turned on when the ®rst stage has been on for a mini- mum of 2 minutes and the temperature differential from the set point is equal to or greater than the set point plus the deadband plus 2 degrees.

Clock Backup Ð In the event of a power loss, the ther- mostat will keep time for a minimum of 48 hours without external power or batteries.

Fan Operation Ð If Fan On is selected, the fan will run continuously during occupied schedule (except when Mode is switched to OFF). The fan will be off during unoccupied schedule except during heating or cooling operation.

If Fan On is not selected, the fan will only operate during heating or cooling operation.

Emergency Heat Ð Emergency heat is available only for heat pump applications. To turn on emergency heat, press and hold the Override button. While holding the Override button, press the UP button. An ``EH'' will be displayed. Dur- ing emergency heat, the fan will operate and the second stage of heat will be energized (locking out the ®rst stage com- pressor). To exit emergency heat, press and hold the Over- ride button. While holding the Override button, press the UP button. During emergency heat, only OFF and HEAT modes are available.

Electric Heat Ð When the Electric Heat option in the advanced setup is set to ON (con®gured by installer), the thermostat will turn on the fan immediately any time there is a heat demand. This feature should only be used on elec- tric heating applications. Do not use with gas heat.
