Function, Technical Data, Order Code

The adjustment devices either communicate with the control component of the VAV terminal unit via an additional connection (service socket) or, for certain control components, via the normal signal line, e.g. actual value signal. The adjustment devices detect the connected controller type and enable access to the operating values and parameters respectively available. The values are displayed. Operation is with push buttons.
