An electric heater thermostat is very helpful gadget that can help regulate the heat temperature in your home. These things also stop functioning well over time so thermostats should be replaced. It is recommend that if your home has a manual thermostat regulator to switch to an electrical thermostat. Not only will it take away the hassle of manually adjusting it but also it can help with saving energy, as it will automatically adjust to the temperature of your choice once you set it.

Step 1 – Turn Off Power

Turn off power source to your electric heat thermostat. With just about any repairs or re-wiring it is always better to shut off power before you touch any wires to avoid electrocution. Simply shut off the breaker that powers the area where your electric thermostat is located. To be completely sure, you may use a non-contact voltage tester or multimeter to check if the power is off.

Step 2 – Install Thermostat

Install the electric heater thermostat. Always read the instruction manual for proper installation. Check the back of the thermostat and find the diagram that shows the line and load connections. The line connection will connect to the feeder wires coming form the breaker in the electric panel while the load connection will connect to the wires that feed the heater.

Step 3 – Connect Line

Connect line connection to the electric heater thermostat. Find the feeder wires and strip about 3/4 inch of the insulation from the wires. Typical colors for such wiring would be green, black and white. The black wire would typically be the hot wire. The white would be the neutral wire and the green would be the ground wire. Sometimes the green wire may also be bare in color. Connect the black colored wire to the line side of the electric thermostat. Connect the white wire to the load neutral wire and the green, which is the ground wire, will connect to the load ground wire. They should now be pigtailed to the heater ground screw.

Step 4 – Connect Load

Connect the load connection to the electric heater thermostat. The load connection is the wire that will run from the thermostat to the electric heater itself. Now, connect the black wire to the load side of the thermostat. Now that you have already connected the load neutral and ground connection, you have completed the thermostat connection.

Step 5 – Mount Thermostat

Mount the electric heater thermostat. Take your mounting screws provided with the thermostat and then install the thermostat to either the baseboard heater or the junction in the wall.

Step 6 – Test Thermostat

Turn power on and test your heater thermostat. Making sure all connections are intact, you may turn on the power source to your thermostat. To trigger the thermostat switch, turn the thermostat clockwise. You will hear a click when the contacts pull in and there should be electricity flowing through it. Observe and feel if heat starts coming out of your heater.
