Setting Or Changing The Weekday 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 1 cooling temperature.
Your Aprilaire Thermostat allows 1 program for Monday through Friday and 1 program for Saturday
and Sunday. Complete the chart on page 4 with your desired temperatures and time schedules
before beginning programming.
NOTE: It will take some time for your 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.
