Alarm Code Cause Possible solution Reset Alarm relay Action
Probe HPS disconn. ABP07 Pressure probe
HPS broken or
disconnected
Check:
• that probe HPS is correctly connected to terminals
J3.3-J3.5 and receives power from J3.1.
If necessary, replace the probe.
Manual Active Shutdown
Model not set ABC01 Unit model not set Set the unit model on screen Df05 according to the
part number shown on the cabinet door Automatic Active Shutdown
WTS alarm ABE01 Water treatment
system alarm
If input from water treatment system alarm relay is
enabled
Check the water treatment system upstream of
humiFog Direct Automatic Active Shutdown
High bypass press. ALA06 Water pressure in
bypass > 4 bars
Possible return of pressurised water through the
bypass. 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.
Manual Active Signal
High bypass temp. ALA08 Warning WRA12
activated more than 3
times in 1 hour
Possible extended recirculation of water through the
bypass. Check:
• 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
Manual Active Signal
c.pCOe offline ALA11 c.pCOe disconnected
from c.pHC or wired
incorrectly
The c.pCOe expansion that controls zone 2 is offline.
Check:
• 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).
Automatic Active Signal
T mem. write error ALM01 Problem on the
electronic controller
Reload the default parameters from screen Df06 and
reconfigure the unit. If the problem persists, replace
the controller. Manual Active Signal
Too many writes to T mem. ALM02 Problem on the
electronic controller
Reload the default parameters from screen Df06 and
reconfigure the unit. If the problem persists, replace
the controller. Manual Active Signal

zone 2 broken or
disconnected
Check the connection of the limit probe in zone 2 to
terminals J2.U2-J2.GND-J9.+Vdc of c.pCOe Manual Active Signal
