How low or high should I set my thermostat when I’m not home?
We recommend a setback between 5 and 8 degrees in either direction. Most programmable thermostats learn how long it takes to satisfy the target temperature at a given time and will operate the system in advance of that time to satisfy the call. A large setback could wind up costing you more.
