Universal two-zone programmable microprocessor controller for control of cable snow melting systems installed on roads, steps, parking lots, ramps or for anti-icing and freezing of drainpipes, gutters, roof surfaces.
It is possible to control two independent zones on the Ground and/or on the Roof in any combination with a total of up to 4 sensors connected.
The digital microprocessor sensor contains a humidity sensor and a temperature sensor in one housing.
A system with DEVIreg™ 850 III includes a regulator, power supply(s), Roof sensor(s) and/or Ground sensor(s).
The regulator and power supply are installed on a DIN profile.
