Adjustment devices

Functional description

The adjustment device communicates with the controller using the voltage signal line for the actual value or setpoint value.

The adjustment device recognises the controller type and allows access to the available operating values and parameters.

The values are displayed. Operation is with push buttons.

Order example: AT-VAV – S

Installation and commissioning

• Recommendation: The signal line for the individual adjustment devices should be connected in an easily accessible place; this avoids having to open any false ceilings for inspection or service at a later stage.
• Easily accessible places include: switch cabinet, floor distribution box, or an unused terminal on the room temperature controller
• Important: The ground (and perhaps 24 V) must also be available.
