Attic fans are an effective and energy-efficient way to keep your home cool. A thermostat can be installed in the attic to ensure that the temperature stays within a comfortable range. This article offers a step by step guide on how to wire an attic fan thermostat.

Step 1: Choose the Right Thermostat

The first step is to pick the right thermostat for your fan. There are two types of thermostats: line voltage and low voltage. Line voltage thermostats can be used with fans up to 1.5 horsepower, while low voltage thermostats are recommended for fans with higher power ratings. Be sure to check the power rating of your fan before selecting a thermostat.

Step 2: Prepare the Wiring

Once you have selected the appropriate thermostat, you can start wiring the fan. You will need a circuit breaker, wire strippers, and a pair of pliers. Start by turning off the power to the fan. Then, disconnect the fan and remove the old thermostat. Next, strip the wires and connect the new thermostat according to the wiring diagram.

Step 3: Install the Thermostat

Now that the wiring is complete, you can install the thermostat. Begin by drilling a hole in the wall for the thermostat. Then, insert the thermostat into the hole and secure it with screws. Finally, connect the wires to the thermostat, turn on the power to the fan, and set the temperature.


By following these simple steps, you can easily install an attic fan thermostat. Installing a thermostat can help keep your home cool and reduce energy costs. Be sure to follow all safety precautions when working with electricity and consult an electrician if you need assistance.
