Briidea Roof De-icing Cable Controller supports up to 1800 watts of power output, with a panel containing indicator lights, easy to read the status of the equipment, mainly used to automate the control of roof heating/de-icing cable work status. Compared to the heating cable (starting to work below 3°C and shutting down at greater than 10°C) with its own thermostat, the Briidea Controller is triggered to heat up and shut down at a lower temperature (starting to work below 0°C and shutting down at greater than 2°C), saving more money on electricity, and has a humidity sensor requiring water to exist before heating, making it safer and more reliable, is your ideal choice.
