Conventional Recovery Recovery starts at the time programmed into the thermostat; house reaches comfort temperature shortly thereafter. Energy-saving temperature The lower (heating) or higher (cooling) temperature that lets you save on heating and cooling costs when you're asleep or away. Also called the setback (heating) or setup (cooling) temperature. Program The times and temperatures you set to define the comfort and energy savings periods for each schedule (weekdays, Saturday, Sunday). Programmed Recovery Recovery automatically starts early enough so your house is at the comfort setting by the time you've chosen. Set point The temperature you set on the thermostat. The thermostat turns the heating or cooling equipment on and off to maintain this temperature at the thermostat location until another temperature setting goes into effect. Setup Raising the temperature in the house for a set period every day in summer for energy savings. The higher temperature is the energy saving temperature. 35 Period key One of the four keys--WAKE, LEAVE, RETURN, or SLEEP--that you press to check or program the start time and temperature for a time period. Check that heat or cool system power is on. If you use batteries, replace with fresh ones. Make sure thermostat is correctly mounted on base. You have reached the temperature setting limit. The setting range is 7° C to 31° C. In models with automatic heat-cool changeover, the COOL temperature setting must be at least 2° C above the HEAT temperature setting. Programming has been lost because of a power outage. Check that backup batteries are installed correctly. Check the program times for the period in question. Be sure that AM and PM indications are correct. Make sure the current day and time are correct. If using Programmed Recovery, remember that the furnace or air conditioner comes on before the WAKE and RETURN start times so the house will be at the desired temperature when the period starts.
