Möhlenhoff Alpha regulator direct Std. 230V, RD 20203-11N5 230V, disc
The Alpha Regler direct Display is a high-quality room temperature controller for recording and regulating the desired room temperature.
Even with directly connected actuators, simple individual room control is possible. In conjunction with the Alpha Basis direct connection unit, a perfectly coordinated overall system for surface temperature control can be implemented.
The desired room temperature is set and the unit is operated via the rotary knob with a rotary-push mechanism and soft detents. The symbols are always clearly displayed on the high-quality screen, which is easy to read and language-neutral.
The Alpha controller direct Display receives its supply voltage via the Alpha base direct or a separate voltage source.
