Connection to user selection and modbus

User selection: Connection to the user selection can be used, for instance, to control operation of a
cooker hood. This happens via a potential free contact in the cooker hood that sends a signal to the
unit. The unit then increases ventilation when the cooker hood is on. Connection happens in pin 4 and 5
of the 8-pole plug.
User selection can also be used for other functions such as for creating imbalance in supply air and
extract air ventilation.
Modbus: You can communicate with the unit via modbus, which can be connected in pin 1 (GND), pin 6
(A1) and pin 7 (B1) of the 8-pole plug.
Please consult the user manual for software settings etc.
Connect the plug to the unit in point 3: Connections overview.
