    Can I replace 4 wire thermostat with a 2 wire thermostat?
    On my wall I have a 4 wire thermostat, the wires are black and red, I have purchased a new thermostat and it has only two wires which are also black and white. I was woundering if someone could tell me if it can be changed or if I need to purchase a 4 wire thermostat. Thanks

    Depends on what the thremostat controls. If it's a 24 volt heat only system, then probably. If it's a line voltage system such as for electric heat then probably not. What make was the old thermostat? (make and model #)
