Setting Or Changing The
Weekday Program For Heating Mode
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 6 with your desired temperatures and time schedules
before beginning programming:
NOTE: 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.
