Thank you for your question on the model CWT45 thermostat. The CWT45 is an optional thermostat designed to cut off the power going to the motor of a solar powered attic ventilator at 50 degrees Fahrenheit. It is not designed to be used with any other fan. We do sell a wall mounted thermostat, model 70TW, that is designed to be used with our ceiling and wall mounted exhaust fans.
