120v Line Voltage Thermostat Wiring Diagram

In short the red wires from the switch connect one each to each of the incoming 240vac line voltage wires of the heating circuit.

120v line voltage thermostat wiring diagram. To turn the device on and off. All these different names refer to the same one type line voltage thermostat. Our photos and wiring diagram for a marley d 26 wall mounted line voltage thermostat illustrate how this simple 240vac thermostat is wired to the electric baseboard heater. Line voltage thermostats are usually known in different names like line thermostats inline thermostats high voltage thermostat 120 volts 240 volts thermostat single pole double pole thermostat or 2 wire 4 wire thermostats.

Unlike the low voltage thermostats that control central heating and air conditioning systems electric baseboard heaters use line voltage thermostats that are installed as part of the full voltage circuit powering the heater. A line voltage thermostat is for a simple heater or cooler and it has only one function. The thermostat can be mounted directly on the heater itself or it can be mounted on the wall so that the circuit wiring passes through the thermostat first on the way to. Wiring diagram pictures detail.

It connects directly to the 110 or 220 volt power supply not to a 24 volt transformer.
