Thermoelectric valve drive 230 V. Thermoelectric valve drive for opening and closing valves. For 2-step or PWM control of heating, air conditioning and ventilation systems, individual room control of surface heaters, control of heating circuit distributors. For radiators, convector heaters, cooling ceilings. Operation is carried out by the heating actuator REG-K/6x24/230/0.16A, fan coil actuator REG-K or a room temperature control unit (230 V) with 2-step or PWM output. Valve adapters permit compatibility with a variety of valve bodies and heating circuit distributors. Functions: First-open function: The drive is factory-set to de-energised open. This allows the heating to be operated during the building shell phase. De-energised closed. Functional display (open, closed, intermediate settings). Adjustment control. Plug-in connecting cable.
