Automatic
HighLimitCutout
Indicates that the high limit cutout has been activated due to a humidity reading that
exceeds the high limit setpoint. Ensure that the high limit humidistat is operating correctly
and that the distance between the sensor and the steam dispersion manifold is sufficient
(4.6 m).

If that the high temperature switch has been activated due to an abnormal temperature
reading, ensure that the humidifier is not operating below standard water level and verify
the operation of the water level sensor.
Automatic
WtrLvlLow
Indicates that the resistive low water level sensor is defective or incorrectly wired. Check
sensor and verify wiring.
Automatic
WtrLvlHigh
Indicates that the resistive high water level sensor is defective or incorrectly wired. Check
sensor and verify wiring.
Automatic
WaterTemp
Indicates that the evaporation chamber water temperature sensor is defective or incorrectly
wired. Check sensor and verify wiring.
Automatic
FoamSensor
Indicates that the foam cutout sensor is defective or incorrectly wired. Check sensor and
verify wiring.
Automatic
SSRTemp
Indicates that the solid-state relay temperature sensor is defective or incorrectly wired.
Check sensor and verify wiring.
Automatic
CabinetTemp
Indicates that the cabinet temperature sensor is defective or incorrectly wired. Check
sensor and verify wiring. (Only applicable for humidifiers having the weatherproof option.)
Automatic
ContactorsFuse
Indicates that there is an issue with the printed circuit board fuse. Check the status of the
fuse and replace it if defective.
Automatic
FanFault
Indicates that there is a problem with the SDU fan. Verify the signal and the operation of
the SDU fan. (Only applicable for humidifiers having the SDU option.)
Automatic
MemoryCard
Indicates that the SD card has been detected, but it is not operating correctly or is non-
functional. Verify the SD card and replace if defective.
Automatic
Foam
(Warning)
If
Detected
is displayed, it indicates that the foam sensor has detected foam and the
humidifier is now draining. Once the drain cycle has ended, the warning message will
disappear.
Automatic
WaterLevel
(Warning)
If
Calib
is displayed, it indicates that there is a calibration error with the water level sensor.
Verify that the
WtrAutoCalib
setting is set to
Always
to ensure automatic calibration.
If
Replace
is displayed, it indicates that the capacitive water level probe has drifted and the
resistive probes have been activated until the capacitive probe is recalibrated. If the error
persists, the warning message will change into the alarm message described below.
Automatic
WaterLevel
(Alarm)
If
Defect
is displayed, it indicates that the water level sensor is defective or not working
properly. Verify its operation and replace it if necessary.
Manual *
FailedPump
Indicates that there was an error during draining due to a pump failure. Verify that the drain
pump is operating correctly and that it is not being hindered or obstructed.
Manual *
FillTimeout
Indicates that the water level sensor has not reached the desired value within the
programmed delay. Verify and remove any obstructions in the water inlet line and verify
that the shut-off valve is not closed.
Manual *
BlockedPiping
Indicates that there was an error during draining due to a blockage in the pipes. Verify and
remove any obstructions in the piping and ensure that the drain outlet is not clogged.
Manual *
HeatTimeout
Indicates that the water temperature in the evaporation chamber has not reached the
boiling point within the programmed delay. Verify the temperature of the supply water.
Manual *
Overheat
Indicates that the evaporation chamber temperature sensor has detected a temperature
reading greater than or equal to 105°C. Verify the operation of the water level sensor and
ensure that the water supply piping is not obstructed.
Manual *
WaterLeak
Indicates that a water leak has been detected. Verify the water line for signs of leaks and
ensure that all piping and water connections have been properly installed and secured.
Manual *
TankBlocked
Indicates that there was an error while filling the evaporation chamber due to a blockage in
the pipes. Verify and remove any obstructions in the piping and ensure that the water inlet
is not clogged.
Manual *
RefillDelay
Indicates that the evaporation chamber has not been refilled with more water within the
programmed delay after it has begun evaporating, due to a blockage in the pipes. Verify
and remove any obstructions in the piping and ensure that the water inlet is not clogged.
