Möhlenhoff Alpha controller direct 230V, R 20203-10N4 analogue 230V


The Möhlenhoff Alpha controller direct analog 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 OEM Alpha Basis direct connection unit, a perfectly coordinated overall system for surface temperature control can be created. The desired room temperature is set using the rotary knob with soft detent. Setpoint calibration and a limitation of the setting range are also possible. possible.

The OEM Alpha controller receives its supply voltage analog direct via the OEM Alpha base direct or a separate voltage source.
