Your thermostat is already set up and prepared to use. Setting the time and day is all that is required.

Your system can be easily programmed to save the most energy possible. Four time periods per day can be programmed, with separate settings for weekdays and weekends. You can set the temperature and timer to the moment you get up and stay there till you leave for the day.

You can also set to the time you go from home and the desired temperature while you are gone (usually an energy-saving level).

Set the temperature to what you prefer in the evening until bedtime and the time you arrive home. Lastly you can set the time and temperature for when you plan to go to bed (usually an energy-saving level).

This thermostat has been programmed to use energy-saving program settings. They advise using these settings since they can cut your heating and cooling costs by up to 33 percent.

Your air conditioning or heat pump system’s compressor is protected by the built-in compressor security feature, which aids in avoiding damage. If the compressor is resumed too soon after shutdown, damage may result.

The compressor must wait five minutes before resuming due to this function. The message Cool On will show on the display while you wait (or Heat On if you have a heat pump).

The notification stops blinking and the compressor starts on when the safe wait period has passed.
