Protocols and
configuration
The humidifier can be connected to a supervisor via serial (BMS) or Ethernet network. The Carel, ModBus
and BACnet protocols are supported as standard by the units.

Tab.11.a
To configure supervision on the BMS port (1), go to “SETTINGS – SUPERVISION”, specifically screens Eh01,
Eh02 and Eh03. If connecting the supervisor to the Ethernet port (2), set the network parameters (DHCP,
IP address, subnet mask, gateway, DNS) on screen Eh04. For other supervisor protocols, select the Carel
protocol on the BMS serial port and use the Carel external gateway (supernode for humidification:
SNU0000EM0), combined with the desired supervision card (depending on the protocol).
Note:
l use CAT-5 STP Ethernet cable, max length = 100 m. To connect the shield, use the earth connector
provided on the controller;
l for BMS and Fieldbus, use shielded cables with the shield connected to earth.
