There are several tips to follow to ensure that your programmable thermostat gives you service for many years. They include the following: Set your ideal temperature for hours when you are home and awake. Plan for the events where you will want to adjust the temperature, such as when going to work, returning from work, waking up, and going to bed. Adjust the thermostat to reduce your energy usage while you are not at home. Override the regular temperature programming for when you will be away from home for a long time. Set the temperature adjustments before any events. For example, reduce the heating and cooling 30 minutes before leaving the house or 10 minutes before bed. You can also set the thermostat to the preferred temperature around 30 minutes before you return home.
