The digital control unit can, for example, switch Vitramo heating elements with a total nominal output of up to 2300 watts. Modular device for installation as a sub-unit on the mounting rail. Weight approx. 0.2 kg. NOTE: Only technically useful in conjunction with heating elements from the VH and VH-I series and an integrated temperature sensor. If required, the digital control unit DS-P can control a heating area that includes one or more heating elements and limit the achievable surface temperature of the heating elements. To do this, the Vitramo heating element must be equipped with a sensor that measures the surface temperature. NOTE: In every room in which heating elements are controlled in this way, at least 1 heating element must be wired to the control unit.
