The power is supplied by a transformer, and when the thermostat makes contact between the 24 volt power and one or two of the other wires, a relay back at the heating/cooling unit activates the corresponding heat/fan/cool function of the unit(s).
Double check with a tester to make sure the power is off before proceeding. To work properly the electric water heater thermostat needs to be positioned firmly against the wall of the hot water tank. It is held in place by a spring steel bracket. There are no screws that actually hold it in place.
