m Danger to life due to electric shock!
With regard to connection work on a live controller, there is a risk of fatal electric shock.
The actuator NR 24 of the three-way mixer can be controlled by control units using the 24 V (0-10) output. Connection
to control unit pursuant to ventilation unit installation and operating instructions.
The rotation angle is limited to 90°. When the limit stops are reached, the actuator will be switched off electrically and
currentless. In case of control system errors, the actuator can be switched to manual operation by means of an ad-
ditional rotary switch.

3 .3 .2 Assembly of actuator
− Rotation lock (1) fixed to mixer housing.
− Insert adapter (2) as far as possible in the mixer plug (3). Note flattening!
− Set mixer plug so that the nose of the adapter points down. In this position, the mixer plug closes the outlet
downwards (full bypass operation, cold).
