Thermoelectric actuator for opening and closing valves. For 2-point or PWM control in heating, air conditioning and ventilation systems, individual space control of surface heating, control of heating circuit distributors, radiators, convectors, cooling ceilings. It is controlled by a REG-K fan coil drive or a room temperature controller (24 V) with 2-point output or PWM. Adaptation to the various valve bodies and heating circuit distributors is possible with the help of valve adapters. Functions: -First-Open function: As delivered, the actuator is open in the de-energized state. This means that heating operation is also possible during the rough construction phase. - Closed when not powered. -Display functions (open, closed, intermediate positions). - Settings control. - Disassembly protection. - Plug-in connection cable. - push-in mounting.
