Möhlenhoff Alpha controller direct 230V St., RD 20203-11N4 230 V Triac
The Alpha controller direct display is a high-quality Raumtemperaturregler for recording and controlling the desired room temperature.
Simple individual room control is possible even with directly connected actuators. In conjunction with the Alpha Basis direct connection unit, a perfectly coordinated overall system for surface temperature control can be created.
The desired room temperature is set and the device is operated using the rotary knob with a turn-press mechanism and soft-lock mechanism. The symbols are always clearly displayed on the clear and language-neutral display of the high-quality screen.
The Alpha controller direct display receives its supply voltage via the Alpha base direct or a separate voltage source.
