Adjustable Heating Cycle Times (also called Anticipation). Cooling is not adjustable.
Your thermostat is designed to cycle on and off in heating or cooling, keeping your building in an accurate temperature range. This maximizes your comfort by keeping the room temperature very close to the temperature you set. It is not unusual for your thermostat to be set for 70 and cycle on and off at 70 keeping you right on target.
Most 1F80 Series thermostats have a feature that allows you to increase or decrease the cycle times in heating. This is useful if you think your cycle times are too long or too short.
See your thermostat Operating Instructions or check this link for procedure to adjust the cycle time (anticipation).
On Single-Stage models, heating can be set to A or H. Cooling is not adjustable. On Multi-Stage or Heat Pump models, heating can be set to F or S.
The chart below shows how this adjustment range affects thermostat performance.
† These numbers are approximate and represent operation with a typical system. Actual temperature differentials and run times will vary based on your building and equipment, as well as outdoor temperature conditions.
No Heat:With the system set to heat, when the set point temperature is raised or lowered past the room temperature, the thermostat will make a soft click sound within about 5 seconds. Usually the sound indicates correct thermostat operation. If the heat does not come on after raising the temperature and hearing the click, check the fuses or breakers, make sure the furnace is switched on, and verify the blower compartment door is closed properly. If no click sound is heard try resetting the thermostat as described below. If the no heat or no cool condition persists after resetting the thermostat, you may wish to contact your heating/cooling service person for assistance.
No Cool:Air conditioning systems usually include an outdoor compressor and an indoor blower. With the thermostat set to COOL and the temperature lowered below the room temperature by a couple of degrees there can be up to a five minute delay before the thermostat activates the compressor and an indoor blower. If both the compressor and an indoor blower are running and the air is not cool it may indicate loss of refrigerant in the compressor. If the blower or compressor do not come on or do not shut off try resetting the thermostat as described below. If the no heat or no cool condition persists after resetting the thermostat, you may wish to contact your heating/cooling service person for assistance.
