« NO INLET WATER P4» ALERT
- a « NO INLET WATER P4 » information is shown when the cylinder is not correctly filled.
In this case, the humidifier is stopped and the remote general fault alert is initiated. The remote main-
tenance alert is kept off.
- Items to check : F2 inlet valve fuse, drain valve (could be clogged by pieces of calcius) - steam hose
(pockets of water) - power voltage
—
TI voltage reading (condition of the torroidal of intensity
—
power
wire passing through TI hole).
- Reset : switching off and on the humidifier will clear the display but will not remove the message
which will be shown again after a while. .
- This fault can be disabled inside the menu (please contact your authorized distributor).This will sup-
press the detection.
- Simulation : Tap off the water supply. Time before detection : about 8 mn.
« SEE DRAIN CIRCUIT P5» ALERT
- This alert is shown when the draining is incorrectly operated.
In this case, the humidifier is stopped and the remote general fault alert is initiated. The remote main-
tenance alert is kept off.
- Items to check : F3 fuse (if found faulty, replace fuse and drain valve solenoid), correct water drai-
ning by pressing manual drain button). If no drain, clean cylinder and draining circuit.
- Reset : switching off and on the humidifier will clear the display but will not remove the message
which will be shown again after a while.
- This fault can be disabled inside the menu (please contact your authorized distributor).This will sup-
press the detection.
- Simulation : disconnect the solenoid coil of the dain valve. Time before detection : sereval hours.
« WATER LEAKAGE DETECTION P6» ALERT
-
REMINDER
: to enable this function, the optional water leakage detection board should be installed
first.
- When the alert message is shown, the remote general fault alert is initiated, the cylinder is drained
fully and the humidifier is brought to a halt. The remote maintenance alert contact is kept off.
- Items to check : water at the water sensor in the humidifier humidity compartment.
- Switching off and on the humidifier will clear the message only for a while but will not remove the
alert which will be shown again 15 seconds after the humidifier detects it again.
- This fault can be disabled inside the menu (please contact your authorized distributor).This will sup-
press the detection.
- Simulation : drop a water drop on the water sensor.
«CLEAN CY DRAIN VALVE P8» ALERT
- This alert is shown when the draining cannot be operated.
In this case, the humidifier is stopped and the remote general fault contact is trigged on. The remote
maintenance contact is kept off.
- Items to check : F3 fuse (if found faulty, replace it and replace drain valve solenoid coil); operate a
manual draining to control correct water flowing. If incorrect, check or replace cylinder and water pi-
ping.
- Switching off and on will clear the message only for a while from the display but will not remove the
alert which will be detected and displayed again some minutes after.
- This fault can be disabled inside the menu (please contact your authorized distributor).This will sup-
press the detection. - Simulation : generate over currents
