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 1 program for Monday through Friday and 1 program for Saturday and
Sunday. 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.
