It’s a single pole thermostat, since it only switches one panel wire connection to the heater. However, unlike most other single pole thermostats, it requires a L2 (N) connection. So, more than two wires are needed for installation.
How many wires do I need for a single pole thermostat?
It’s a single pole thermostat, since it only switches one panel wire connection to the heater. However, unlike most other single pole thermostats, it requires a L2 (N) connection. So, more than two wires are needed for installation.
Where do thermostat wires go?
Thermostat Wiring Tips If your thermostat controls your heat, you will have a white wire. The Y wire is yellow and connects to your air conditioning compressor. The G wire is green and connects to the fan. Rc and Rh: The red wire(s) are the power source for your thermostat.

How do I know if I have a single pole or 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.
How do line voltage thermostats work?
A line-voltage thermostat can control a single baseboard heater or several heaters wired together. The thermostat works by sensing the temperature of the room and controlling the amount of current that passes through the wires to the heater.
Whats the difference between a single and double pole thermostat?
A single pole thermostat operates off one circuit, and therefore cannot operate separately. … Because of this the single pole thermostat cannot be turned off, but only turned down. A double pole circuit, however, has two directional currents providing a double pole thermostat the ability to turn off completely.
How do you wire a baseboard heater?
- Connect one supply wire to one heater wire.
- Connect remaining supply wire to remaining heater wire.
- Replace wiring compartment cover and secure with screw previously removed.
- Turn power back on at the electrical panel board.

Locate the red wire(s) on the ther- mostat. These are the L1 and L2 and attach to the power supply. The black wire(s) are the load side and attach to the heater. Attach one red wire from the ther- mostat to the white wire from the power supply with a wire nut.
Article first time published onWhat color wire goes where on a thermostat?
This is the most typical thermostat wiring style, and it applies to systems that regulate both heat and air conditioning. The wires are typically arranged as follows: red for 24-volt hot, white for heat, yellow for cooling, green for the fan, and blue for common (although the common wire may be a different color).
What is the common wire on a thermostat?
The C wire, or “common wire” enables the continuous flow of 24 VAC power to the thermostat. Technically speaking, power flows from the R (red) wire, but not continuously (not on its own, anyway). To make it continuous requires a common wire to complete the circuit.
What happens if you wire a thermostat wrong?
Potential consequences of improper installation could include: Electric shock. Blowing a circuit breaker. Damaging the thermostat unit, the electrical system or even the AC/furnace unit itself.
What color wire goes where on a Honeywell thermostat?
Meaning of Wiring Terminal Letters W (white) controls the auxiliary heating elements. Y (yellow) controls the compressor on the cooling system. G (green) controls the fan. C (blue or black) provides a return path to the transformer.
Why is there a jumper between R and RC?
Effectively there isn’t a second RH wire, although there is an RH terminal. However, the heating still needs to be controlled, so a wire known as a jumper is connected between the RC and the RH terminals so that power gets to the heating control part of the thermostat.
How many wires should my thermostat have?
The most basic thermostat has 2 wires; usually a red and a white wire. Two wire thermostat wiring is used for furnaces only and usually doesn’t need a “C” or “Common” wire.
What does single pole or double pole mean?
A single-pole switch controls just one circuit. A double-pole switch controls two separate circuits. … When the switch is opened, the terminals are not connected, so current does not flow. A double-throw switch connects an input terminal to one of two output terminals. Thus, a double-pole switch has three terminals.
Can I use a 2 wire thermostat on a 4 wire system?
Replacing an outdated four-wire thermostat with a newer model that uses two wires is not complicated, once you purchase the thermostat from a home-and-garden shop or hardware store. The procedure to install the new thermostat is straightforward and does not require the assistance of a certified electrician.
How do you wire a 240 volt thermostat?
- Using wire connectors, connect a hot supply wire, which is typically black, to thermostat wire one (typically it is marked L1 or Line).
- Connect the remaining supply wire, which is typically white, to the second thermostat wire (typically marked L2 or Line).
Can I use double pole breaker for single pole?
There are two different types of switches: the single pole and the double pole switch. … A double pole switch can be used to control light and a fan or 2 lights on separate circuits. It is easy to wire a double pole switch to work as a single pole switch because only one side is used instead of both.
How do you install a thermostat on an electric wall heater?
- Turn off the Electricity. …
- Use the Wiring Schematic as a Guide. …
- Partly Remove the Insulation. …
- Link the Ground Wires. …
- Make the Line Connections. …
- Make the Load Connections. …
- Arrange the Wires. …

How do you test a baseboard heater thermostat?
To perform the test, turn off the circuit breaker and then take the thermostat off the wall, using a screwdriver. Remove all the thermostat wires from the control. Touch one lead to each wire while you hold the other lead on the ground wire. Repeat the test with all the thermostat terminals.
Does MYSA work with single pole?
Mysa is a single pole thermostat. However, Mysa has the ability to turn off the heater despite being a single pole thermostat.
How do you know if you have AC wire thermostat?
Simply remove your current thermostat face from its baseplate and look for the terminal labeled with the letter “c.” If this terminal has a wire attached to it, you have an active “c-wire.” If you don’t see a wire connected to your “c” terminal, you have a few options.
What does L1 and T1 mean on a thermostat?
The L1 and L2 are probably the power connections; Line 1 and Line 2. T1 and T2 are probably the thermostat switch terminals. For heat, T1 and T2 contacts would “close” when the temperature is falling and it reaches the set point.
Will a line voltage thermostat work with low voltage?
A low voltage thermostat will not work with line voltage wiring. Which Thermostat Do I Need? Furnaces and heaters are not easily interchanged and are not made to mix and match. There are advantages to using both types of controls, so the main thing to consider is usage.
Are thermostat wires low voltage?
Virtually all central heating and air-conditioning systems are controlled by a low-voltage thermostat. … These thermostats are called low voltage because they run off a transformer that reduces line voltage from 120 volts to a level somewhere between 12 and 24 volts, depending on the brand of furnace you have.
What are the major differences between the line and low voltage thermostats?
A line voltage thermostat ranges from 120 to 240 volts. It uses more power than low voltage thermostats because it delivers power directly to your heater. Line voltage is more commonly used with radiant, convention, or resistance heat sources. If you have baseboard or wall heaters, you likely have line voltage.
What is the jumper wire for on a thermostat?
Most of your current thermostat’s wires will be connected to your thermostat and go through the wall to connect to your HVAC system. However, some thermostats will have a jumper wire that doesn’t go back through the wall to connect to your system. Instead, a short jumper wire connects two thermostat terminals together.
What gauge wire is thermostat wire?
The most common thermostat cabling is 18/5 (18 gauge, 5 conductor), because 5 conductors typically offer enough functions for a modern thermostat/low voltage device.
Do baseboard heaters have thermostats?
These baseboard heaters are controlled by a thermostat that is on the heater or mounted to the wall. … As the air is heated, it will rise in the room and cooler air will be drawn into the bottom of the heater. There will also be some heat radiating from the pipes, fins, and housing.
