Roof & Gutter De-Icing Controller

Description

The GC-1 roof and gutter de-icing controller is designed
to energize the heating cable only when moisture
conditions exist and there is risk of freezing. If the
temperature is below 3°C (38°F) and the MSG-1 sensor
detects moisture, the controller will apply power to the
heating cable. The cable remains energized until 3 hours
(hold time) after the sensor is dry.
