Digital ice and snow detector including an additional power supply for 35 mm top hat rail, with visual display of the target and actual values via LCD display. Possibility of connecting up to 4 digital humidity/temperature sensors, these can be connected to a common bus line. This eliminates the need for the individual sensor lines to be fed back. The ice and snow detector can control two zones at the same time. Up to 4 sensors can be individually distributed across two heating zones, e.g. a division into a north and south facing zone or a zone with a slope and a horizontal zone or a sunny and a shady area. Outdoor heating combined with gutter heating is also possible with one controller. It is also possible to specify which area should have priority for keeping ice and snow free, so that heating of the area with the lower priority only begins when the area with the higher priority has been cleared of ice and snow.
