What is the difference between a double pole and single pole thermostat?
Both are types of line voltage thermostats, which typically control radiant, convection or resistance heaters. The difference is all about the off setting — or a lack of one. Double pole stats have a true off setting. Single pole thermostats don’t.
What is a SPDT thermostat?
Also known as inline thermostats, they typically connect to wires supplying 120V or 240V of power to the heating or cooling device. They have two or four thick wires coming out of the back that attach with wire nuts to wires in the wall.

What is the difference between a single and double pole thermostat?
If you see two wires coming out of it in the back you have a single pole. If there are four wires, you have a double pole. If you have more than four wires coming out of your thermostat, you most likely have a low voltage one, which would be used to control a central furnace, boiler, or something similar.
What is single pole line voltage thermostat?
Single Pole Thermostats A single pole thermostat has a singular switch that opens or closes the heating circuit. Opening the circuit stops power flow to the heater. While closing the circuit lets power run to the heater, so it can regulate room temperature. This is how a thermostat reaches its setpoint.
What is the difference between single pole and double pole thermostat?
The Basic Difference The very basic difference between a Single pole and Double pole thermostat is – a Single pole thermostat cannot be turned “ OFF ” completely. Hence a single pole thermostat never turns the electric heater OFF by cutting power supply line from the heater.
What is a line voltage thermostat?
Line Voltage Thermostats – 120, 208, 240 Volts – Digital or Mechanical – Programmable or Non-Programmable Line voltage thermostats are designed to directly control electric heaters, such as baseboard heaters, by switching the main power on and off to the heater.
How do I know if I have a single pole thermostat?
If you see two wires coming out of the back of your thermostat, you have a Single pole thermostat in your hand. And if you see four wires coming out of the back, you have a Double pole thermostat in hand.
