If more fans (up to 4) need to be connected to one controller, the connection must have one beginning (CTRL-HS) and one end
(last fan) as shown in the below images:
If the fans are not connected as per Fig.1, there will be a degradation of the communication signal and the fan network may not
function correctly.
Attention: each fan must have a unique Modbus address.
It is recommended that each fan has a dedicated power supply switch since the setting of the Modbus address to
one fan must be carried out when only one fan is connected to the Modbus network.
