Possible solution
Possible blockage of the outlet line. Check:
• correct opening of the NC zone fill solenoid valves (24 Vac
bars when filling or
when open);
washing
• correct opening of the NO zone drain solenoid valves
(0 Vac when open).
Check:
• that probe LPS is correctly connected to terminals
LPS broken or
J16.1-J16.2 and receives power from J3.1.
disconnected
If necessary, replace the probe.
Check:
• that the NTC probe is connected to terminals J5.2-J5.3.
probe broken or
If necessary, replace the probe.
disconnected
Check:
• that probe RHP is correctly connected to terminals
RHP broken or
J3.3-J3.5 and receives power from J3.1.
disconnected
If necessary, replace the probe.
Set the unit model on screen Df05 according to the part
number shown on the cabinet door
If input from water treatment system alarm relay is enabled
system alarm Check the water treatment system upstream of humiFog

Possible return of pressurised water through the bypass.
bypass > 4 bars Check:
• that the bypass drain solenoid valve BYP is able to drain
water;
• correct operation of the mechanical overflow valve
(opens at 4 bars).
If necessary, replace the bypass drain solenoid valve BYP
and/or the overflow valve.
Possible extended recirculation of water through the
activated more than 3 bypass. Check:
times in 1 hour • that the humidification capacity set on screen Dc18 is
equal to the no. of nozzles x capacity of each nozzle;
• that the zone can deliver a flow-rate of water ≥ the
minimum flow-rate supplied by the pump;
• that the NTC probe is connected to terminals J5.2-J5.3
The c.pCOe expansion that controls zone 2 is offline.
from c.pHC or wired Check:
incorrectly • that the unit model is exact (the alarm goes off if
the cabinet is single zone but the c.pHC controller is
configured for two zones);
• that the polarity (+, -, GND) of the wiring between the
c.pHC (terminal M3) and c.pCOe (terminal J6 BMS) is
correct, as shown on the wiring diagram;
• that c.pCOe is powered (24 Vac between G-G0 on
terminal J1).
• Change the pump oil after the first 50 hours of
required operation
• Maintenance of the pump' s mechanical components and
request pump oil change is required every 3000 operating hours
Reload the default parameters from screen Df06 and
electronic controller reconfigure the unit. If the problem persists, replace the
controller.
Reload the default parameters from screen Df06 and

controller.
Check the connection of the main probe in in zone 1 to
zone 1 broken or terminals M2.1-M2.2-M2.3 on the c.pHC
disconnected
Check the connection of the limit probe in in zone 1 to
zone 1 broken or terminals M2.4-M2.5-M2.3 on the c.pHC
disconnected
Check the connection of the main probe in zone 2 to
zone 2 broken or terminals J2.U1-J2.GND-J9.+Vdc of c.pCOe
disconnected
Check the connection of the limit probe in zone 2 to
zone 2 broken or terminals J2.U2-J2.GND-J9.+Vdc of c.pCOe
disconnected
Check:
with probe 1 • probe/access point binding
• battery charge
• probe signal level
Check:
with probe 2 • probe/access point binding
• battery charge
• probe signal level
Check:
with probe 3 • probe/access point binding
• battery charge
• probe signal level
