How to Wire an Electric Baseboard Heater Thermostat How to Wire an Electric Baseboard Heater Thermostat
An electric baseboard heater thermostat is an essential part of many different kinds of water heaters. These thermostats are responsible for regulating the temperature level of the water, which helps to ensure that it is ready for cooking, cleaning or bathing as you need it. A thermostat that is functioning properly can help to protect you from spending more money than is necessary on electric and water costs. Read on for a brief guide on how to properly wire an electric baseboard heater thermostat.
Step 1 – Turn off the Power
The most important thing that you must remember to do before beginning this project is to turn off the power. Go to the circuit breaker and turn the circuit switch for the water heater to the off setting. Use a volt meter to check on the power supply at the circuit breaker to be sure that the power is completely off before you continue with the project.
Step 2 – Check the Installation Manual
Each baseboard heater thermostat will come complete with an installation manual. This will be very helpful in determining exactly which wires need to connect with which points on the thermostat and the heater. Generally, the line connection will connect to the breakers and comes from the electric source, while the load connection will be attached to the feeder wires for the thermostat.
Step 3 – Connect the Line Connection to the Thermostat
Begin by connecting the line connection wires. Locate those wires and strip about 3/4 of an inch from the ends of each. There should be three wires here, one black, one white and one green. In most cases, the black wire is the hot wire, the white is neutral, and the green is grounding. Use the Philips screwdriver to unscrew the terminal points on the thermostat where the wires will connect. Fasten the black wire to the line side of the thermostat, then the white wire to the load neutral wire and the green to the load grounding wire. The grounding wire should be attached to the load ground screw.
Step 4 – Connect the Load Connection
Connect the black load wire to the load side of the thermostat. The other two load wires should be connected already to the line wires as detailed in the previous step.
Step 5 – Mount the Thermostat
The thermostat should come with a supply of mounting screws. Use these to mount the thermostat on the side of the water heater in the area in which the thermostat is designed to be attached. Make sure that the thermostat is stable and solidly connected to the heater before leaving the area. Use a screwdriver to adjust the thermostat to the level that you desire.
Step 6 – Restore Power and Observe the Thermostat
Restore power by flipping the circuit back on. Wait for about two hours and check the hot water to see that the thermostat is working properly.
