What is a 2 pole thermostat?

What Is a Double Pole Thermostat? Double pole thermostats (also known as four-wire controls) are line-voltage devices that control the heating equipment with two-directional electric currents. A double pole thermostat is wired into the circuit breakers just like a single point thermostat.

Can you replace a double pole thermostat with a single pole thermostat?

You can use double-pole thermostats as single pole units. Most double-pole line voltage thermostats will break only one pole when cycling on and off. Connecting the poles together in parallel as you planned will not work.

How do I know if my thermostat is single or double pole?

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.

How does a 2 pole thermostat work?

Just like a single pole thermostat, a double pole thermostat is wired directly to the main circuit breaker but will have four wires instead of two. Double pole thermostats have an “off” button and can cut off power completely to the heater, even if the temperature drops below the set temperature.

What does single pole or double pole mean?

What Is A Pole? The pole of a switch refers to the amount of separate circuits that switch can control. Single pole switches can control just one circuit and a double pole switch can control two circuits. So a double pole switch is almost like having two single pole switches, controlled by the same switch.

What does L1 and L2 mean on a thermostat?

A US manufacturer would label them as L1, L2, T1, T2 as you noted, because L1 and L2 are the incoming Line power. L1 and L2 are both “hot legs” of our split phase power system and measure 240v across them, as opposed to 120V if measuring L1 to Neutral.

What is the difference between a 2 pole and a 4 pole thermostat?

Double pole thermostats have an “off” button and can cut off power completely to the heater, even if the temperature drops below the set temperature. Since a double pole thermostat, also known as a 4-wire control, can operate on two separate circuits, this type of thermostat can operate by the same switch.

What is single pole vs double pole?

The pole of a switch refers to the amount of separate circuits that switch can control. Single pole switches can control just one circuit and a double pole switch can control two circuits.

Can I replace a double pole socket with a single pole?

The single pole should be safe, that is why it is allowed. The double might help if for some obscure reason neutral became live. Or for testing and the like where it really does disconnect the appliance. You can not reliably test with things conected to neutral.

What is a pole in electrical terms?

“Pole” indicates the number of circuits that one switch can control for one operation of the switch. If one switch can control one circuit for one operation, it is a single-pole switch. If it can control two or three circuits for one operation, it is a double-pole or a triple-pole switch.

What is a double pole thermostat?

Just like a single pole thermostat, a double pole thermostat is wired directly to the main circuit breaker but will have four wires instead of two. This allows for the thermostat to operate on two separate circuits. Double pole thermostats have an “off” button and can cut off power completely to the heater,…

What is a direct line voltage thermostat?

A Line voltage thermostat (or a high voltage thermostat) – runs on direct line voltage (In America, this is either 120 volts or 240 volts). And this thermostat is used to regulate heating systems that work on direct electricity like a baseboard heater.

What is the voltage of a wall thermostat?

Most homes feature a wall-mounted thermostat that is powered by a 120-volt circuit. But, before the 120-volts gets to the thermostat, it is first wired to a transformer which reduces the voltage all the way down to anywhere between 12 and 24 volts, depending on your furnace.
