NOTICE
Separate AC 24 V supply for field devices (V~)
A separate AC 24 V field supply is required if field devices and Triac outputs use more than
4 VA or have peak loads in excess of 6 VA.
Do not use the external field supply for the triacs. The external field supply is reserved for
field devices only, which in turn, must be controlled by an analog output (Y10...Y30).
Connecting an external supply to the triacs (V~) will destroy the room automation station.
Digital inputs
Digital inputs are not suitable for operating lighting or blinds. Use the KNK PL-Link
pushbutton.
Mounting
The room automation stations can be snapped onto standard rails or screwed onto a flat
surface.
