Power Modulator Electrical Box 3

Featuring four contactors and a built-in ground fault sensor, the Power Modulator 3 allows customers to control one or multiple zones one at a time, thereby saving money and handling a higher amount of power than the average control. This electrical box enables customers to use one contactor per zone, up to four zones. This can be done in one of two ways. Either all four zones can be used for snow melting, or three zones can be used for snow melting and the fourth zone can be used for roof and gutter deicing.

Note: An upper limit temperature sensor is included. This sensor is installed under the surface and measures the ground temperature. This information is used to save energy during snow-melting operation.
