CONNECTION WIRED 3 POSITION SWITCH
You can also control the ventilation unit by wire. When the switch is ope-
rated, the ventilation unit always adjusts the flow rate immediately. It is also
possible to combine the wired switch connection with a home automation
system or other building management system. You can still use the RF
switches to switch back to a lower or higher position. However, both the
mechanical switch and the building management system will no longer
indicate the correct position.
0-10 V CONTROL (BUILDING MANAGEMENT SYSTEM)
You can also have the ventilation unit controlled by a home automation –
or other building management system. You can still use the RF switches to
switch back to a lower or higher setting. In order for the building manage-
ment system to send back the ventilation unit, position 1 of the RF position
switch must be kept pressed for at least 3 seconds. Please consult your
installer before installing a building management system.
