Electric baseboard heaters are good for spot heating areas of your house that central hvac does not reach.
It reveals the elements of the circuit as simplified shapes as well as the power and also signal links between the tools.
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.
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.
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.
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.
In short the red wires from the switch connect one each to each of the incoming 240vac line voltage wires of the heating circuit.
