This controller will only operate when the temperature requires it! A temperature only controller (C10) is available that operates motor whenever freezing conditions exist.
The C-10 thermostat controller is an inexpensive way to control the operation of your de-icer. The C-10 uses an air temperature thermostat to turn the de-icer on when the temperature drops below a set point that you decide. One C-10 controls one 120V de-icer.
Each controller is designed to control ONE unit and save money on your power bills.
