10. HARDWARE BACKUP
For applications that require continuous humidity control, a second
backup unit may be required, which is automatically activated in the
event of a malfunction on the fi rst.
The heaterSteam controller features a dedicated digital input and output
for the backup connection, so as to guarantee, via the normally-open
contact, activation of the second unit.

11. SUPERVISOR NETWORK
11.1 Supervisor network protocols and
confi guration
The humidifi er 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.

To confi gure supervision on the BMS port (1), go to “SETTINGS –
SUPERVISION”, specifi cally 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 humidifi cation:
SNU0000EM0) combined with the desired supervision card (depending
on the protocol).
Note: Ethernet CAT-5 STP cable, maximum length 100 m. To connect
the shield, use the earth connector provided on the controller.
Note: for BMS and Fieldbus, use shielded cables with the shield
connected to earth.

The hardware backup function must be activated on the menu in screen
Ee01. Screen Ee02 is used to set the unit with higher priority in the event
of simultaneous activation. To ensure service continuity, the external
signal or probes must be connected to both units; in this way, both the
main unit and the backup unit will be completely independent. If using
autonomous control with probes, it is recommended to use dedicated
probes for each unit (main probe and limit probe), in other words, do not
share the probes between the units. This will guarantee service even in
the event of probe malfunctions.
Note: the hardware backup function is managed on the
heaterSteam titanium version.
