Can anyone tell if my thermostat needs to be replaced. I have a Lenox Heat Pump with electric aux heater coils and a Lenox 21J7201 thermostat. Last night the outside tempertature dropped down to 12 deg. and the heat pump run almost continuously. Shouldn't the aux. electric coils have kicked in automatically? I had to manually switch the emergency heat on after getting enough courage to get out of a warm bed. I thougtht the electric coil would kink in automatically. It scares me to go away in the winter if the heat pump won't keep the waterlines from freezing. If the thermostat needs to be replaced can you recommend a good DYI unit? Thanks in advance Shel
