Today I installed the 2441TH today, and this happened a couple of times, set for heat and the furnace came on, it changed modes to Cool and shut furnace down. I then changed the mode to auto, and after a heat cycle it's mode changed to off. With temps hovering around zero I can't trust it and put the other thermostat back in.
Any help with what is causing this would be appreciated.
