GC-1


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.
