Next, touch the RETURN button, and set first the time at which you want this program to begin, then both the maximum and minimum temperatures for the temperature you want when you return to the house.

Generally speaking, best energy efficiency is achieved if you allow this range to be somewhat larger while you are absent from the house.

Repeat the process for setting the time and the maximum and minimum temperatures you want for that period when you won't be in the house.

Press the button on the touchscreen labeled for the LEAVE temperature setting.

While home, most people set a relatively narrow range of temperatures, such as 68 and 75 degrees. This will set the temperatures at which the air conditioner and furnace will start up.

Set the minimum and maximum temperature settings, using the other two sets of UP/ DOWN arrow keys on the touchscreen.

Adjust the UP/ DOWN arrow keys displayed on the touchscreen to the time of day you want the wake-up temperature to start.

To set the first temperature program, touch the WAKE UP button on the touchscreen.

To do this, touch the MULTIPLE DAYS button on the touchscreen. You can, for example, highlight Monday through Friday to set the same temperature settings for each day of the work week.

Touch the buttons indicating the days you want to set.

Touch the SCHEDULE button on the electronic touchscreen, then the EDIT button.
