Setting of Modbus addresses
Every ventilation unit must have its own Modbus address.
It is recommended that you change the Modbus addresses so they lie within the interval of 41 - 50.
They will thereby not conflict with the standard Modbus address, 30, which is the standard address for
all Nilan’s ventilation units.

According to the service menu in the software instructions, the Modbus address of the units can be
changed via the control panel.
ATTENTION
The Modbus address is necessary in the setup of the Nilan MultiLink system. It is therefore
important to make a note of which ventilation unit has been given which Modbus address.
Up to 10 ventilation units can be connected to a gateway.
