DTC120-G Control
The Delta-Therm DTC120-G control system is designed to detect snow or ice and automatically activate contractors/relays for roof, gutter, and downspout de-icing cables. The DTC120-G can switch an amp load using the internal 20 amp relay, or it can be used as a 120 VAC input device for a load switching panel.
The roof de-icing system activates when the following two conditions are met: (1) ambient temperature is less than the set point of 40°F and snow or moisture is present on at least one GS sensor.
Once conditions are met the roof de-icing system will be activated until 35-minutes after one of the two activations conditions ceases.
Features include:
- UL Listed roof de-icing applications;
- DTC control panel with a 20A relay output contactor;
- up to four dual sided GS sensors;
- OTS-F1 ambient thermostat;

Roof de-icing cables create a heated drain path, through your gutter and downspout system, for roof melt water to drain properly.
