    Fan Coil Thermostat Wiring

    Hey Guys,
    Trying to figure out the easiest way to explain how wiring will differ between conventional/heat pump thermostats and fan coil thermostats.

    With manufacturers all using different wire color methods- how does one identify the 3 extra fan speed wires that clearly differentiate this type of thermostat from the others?

    what happens when all the wires are the same color?
    It`s better to be silent and thought the fool; than speak and remove all doubt.
