The ARU10 room unit is intended for fixing assembly on a wall by means of two screws (4x35) and
dowels (6x30) or on an installation box. The access to assembly openings and to the connection block
is possible after removing the front part of the box. It is necessary to pay attention to the flatness of
the base layer to avoid twisting the back wall of the box and poor contact in the connector of the
terminal block.
The room unit is powered by default directly from the ACD03/ACD04 controller (four-line).
ATTENTION - The person performing the installation and repair of the ACD03/04
electronic controller and accessories must be properly trained and professionally qualified.
All work must be performed in accordance with valid standards and safety regulations!
