Setting Or Changing The Program

Programming your Aprilaire Electronic Thermostat involves selecting the temperature you want in your home and selecting the time you want it to be that temperature. Your Aprilaire Thermostat will allow a maximum of 4 time schedules per day. Each time schedule is known as an “event.” The Morning event is typically when you wake up and is the first event of the day. The Day event is typically set when you leave for work. The Evening event is typically set when you come home from work and the Night event is set when you go to bed. Each event will have 2 temperatures, 1 heating temperature and 1 cooling temperature. The cooling temperature must be at least 2 degrees higher than the heating temperature. Your Aprilaire Thermostat allows a different program for each day of the week. Complete the chart on page 7 with your desired temperatures and time schedules before beginning programming.

Progressive Recovery

Your Aprilaire Thermostat is equipped with a programming feature called “Progressive Recovery.” This feature assures that your house will economically achieve the desired comfort temperature at the programmed time when returning from an economy or setback temperature. For example, if you like a wake-up temperature of 68°F at 6:00 AM from a setback of 65°F it is not necessary to set the morning program for 5:00 AM. The thermostat will automatically start warming your house in advance so your comfort temperature is reached on time.The progressive recovery feature must be activated in order to work.
