Description
The TL8100A1008 is a line-voltage thermostat from Resideo (Honeywell Home) for electric resistance heat — baseboard, convectors, radiant ceiling or panel heaters.
Line voltage is the distinction that matters here. A low-voltage thermostat switches a 24 V control circuit and lets a furnace or boiler do the work; a line-voltage thermostat carries the full heater current itself. They are not interchangeable, and a low-voltage stat wired to a baseboard circuit fails immediately.
The 7-day schedule lets the heat drop back when the room is empty and recover before it is used again. On electric resistance heat, where every watt is billed at full price, setback is the single largest saving available — there is no efficiency to improve, only run time to remove.
Match the voltage and the pole configuration to the heater circuit, and check the amperage of the heater against the rating of the thermostat. A thermostat sized below the load is the most common cause of a line-voltage stat failing in its first season.
