A line voltage thermostat is for a simple heater or cooler and it has only one function.
Line voltage thermostat wiring diagram.
Electric baseboard heaters are good for spot heating areas of your house that central hvac does not reach.
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.
A wiring diagram is a simplified conventional photographic representation of an electric circuit.
The thermostat interrupts the circuit like a wall switch interrupts a light circuit.
To turn the device on and off.
If you are going to put in a baseboard heater make the thermostat set up the best you can by separating it from the heater body this provides more accurate temperature gauging plus it makes it easier for users to access the thermostat.
It reveals the elements of the circuit as simplified shapes as well as the power and also signal links between the tools.
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.
In short the red wires from the switch connect one each to each of the incoming 240vac line voltage wires of the heating circuit.
It connects directly to the 110 or 220 volt power supply not to a 24 volt transformer.
