To activate the progressive recovery mode simultaneously press the PROGRAM and FAN buttons. A small

thermostat icon, “ “, will appear under the clock. Once in this mode proceed with programming your thermostat remembering to use exact times for each event time change.

NOTE: If not using Progressive Recovery, it will take some time for your heating or cooling system to reach the desired temperature when returning from a setback. Therefore, it is suggested you set your program time before the actual time you want your home to reach the desired temperature. For example, if you get up at 7:00 AM and have a 6 degree setback, set your Morning event at 6:00 AM to be sure the desired temperature is reached by 7:00 AM.

NOTE: This thermostat can be programmed with either 2 events per day (day and night) or 4 events per day (morning, day, evening, and night). Before programming the thermostat, decide which setting is best for your personal schedule. The thermostat is factory preset for 4 events per day. To change to two events per day, refer to page 20 “Optional Settings for Additional Thermostat Features,” or contact your contractor for assistance.
