Question: How To Install A Wall Heater Thermostat?

How far should a thermostat be from a wall heater?

The thermostat should be positioned at a height of about 52-60 inches. Since heat rises, if the thermostat is higher than that, the readings will tend to be too warm.

How do you wire a wall thermostat?

Here’s how to wire a thermostat using the color code and, FYI, each terminal’s purpose.

  1. Attach the red wire to the R terminal (Call for heating and/or cooling).
  2. Attach the green wire to the G terminal (Fan).
  3. Attach the white wire to the W terminal (Heat).
  4. Attach the yellow wire to the Y terminal (AC).

How does a wall heater thermostat work?

Mechanical thermostats regulate heat thanks to the expansion of their internal metallic strips. This strip carries electricity through the connected circuit, switching on the heating. As the strip heats up, one of the metals expands enough to open the circuit and switch off the heating, cooling the room down.

Should thermostat be in coldest room?

We would not advise putting the thermostat in the coldest room as this would not be a true reflection of the temperature of the rest of the house. If the thermostat senses cold, it will think that your entire home is just as cold. So it will tell your boiler to work harder which could increase your heating costs.

What happens if you wire a thermostat wrong?

If you get it wrong, the heat will run continuously. Once you have them paired, attach one pair to “24VAC” (R) and the other to “Heat call” (W) on the thermostat. (it will matter on a thermostat with 3 or more functioning wires, be it Fan (G) or common (C) for a smart thermostat.)

Where does thermostat get power?

The thermostat uses 24 volt power coming from the furnace or air conditioner. If there is no power to this wire, the thermostat will not be able to send a signal to the HVAC system to turn it on. You can check for power yourself with a few household tools.

Where do thermostat wires go?

The green wire underneath your thermostat connects to the fan of your furnace or air handler. It terminates at the air handler or furnace. The green wire connects to terminal G on your thermostat.

Can you use a 240V thermostat on 120V?

You can use mechanical 240V thermostats with 120V just by wiring both poles in series. The old thermostat may say somewhere on the thermostat that it is for 24 volt (24Vac) or maximum 30 volts (30Vac). If you see 120 Vac or 240 Vac on the thermostat, a low voltage thermostat will NOT work with your system.

How do I know if my baseboard heater is 120V or 240V?

Switch on the circuit breaker and touch each multimeter lead to one of the 2 wire connections. The multimeter will read and show the voltage being used by your heater. A 120-volt model should deliver readings between 110 and 125 volts, while a 240-volt model shows 220 to 250 volts. You can also expect small variations.
