MPS Roof De-Icing Control
The Delta-Therm MPS roof de-icng control system is designed to detect snow or ice and automatically activate contractors/relays for roof, gutter, and downspout de-icing cables. The MPS can switch an amp load using the internal 30 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 the RG, MMP, or RGS sensor.
Once conditions are met the roof de-icing system will be activated until 75-minutes after one of the two activations conditions ceases.

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