It seems like my furnace is coming on even when it is at the temperature is where it is supposed to be. For example, if I set my thermostat for 68, the heater will kick on even though the temp hasn't dropped to 67. Could my thermostat be bad?
It sounds like your thermostat is digital and doing exactly what it was told to do. If you go into the software in the thermostat you should be able to set your deadband or otherwise know as temperature differential. Most digital thermostats come from the factory set at 1 deg. deadband, offset or temperature differential. Hope this helps.
