Power Modulator Electrical Box 5
The Power Modulator 5 has five contactors that allow customers to operate up to five zones, depending on the sensors being used. This means customers can save money and handle a higher amount of power than the average control because each zone can be controlled sequentially. The zones can be handled in one of two ways. Either four zones can be used for snow melting (zones 4 and 5 will work together as one zone), or four zones can be used for snow melting and the fifth 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.
