Möhlenhoff Alpha-Regler direct 230V St., RD 20203-11N4 230 V Triac Standard 230 V: Heating, fixed reduction difference, reduction input, for actuators with NC direction of action

Möhlenhoff Alpha regulator direct 230V St., RD 20203-11N4 230 V Triac

The Alpha Controller direct Display is a high-quality room temperature controller for detecting and regulating 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 rotary push mechanism and soft locking 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 Basis direct or a separate voltage source.
