Empty drain T: time during which the drain solenoid valve remains open
after correctly measuring the low water level.
Following the water drain cycle, this is the time that must elapse after the
level sensor measures the low water level to ensure the tank is completely
emptied. This is useful if for parameter Fc03 the drain solenoid valve has
been selected as closed in standby.

Production, refi lling times
Tmax prod: maximum atomised water production time (drivers active),
during which the level sensor must signal low water level.
Max Hlev time: maximum time for measuring the high water level.
The humidifi er checks the water level in the tank during production of
atomised water. If the level does not fall, the following faults may have
occurred:
1. piezoelectric transducer malfunction;
2. leaking fi ll solenoid valve;
3. fan malfunction.
If after the time set for Tmax prod (in minutes, default 30), the low water
level has not been reached, atomised water production is stopped and
the wait procedure starts (see the description in Tmax fi ll), after which the
control attempts to resume production. If the condition remains, alarm
EP will be activated, shutting down the unit. If after a percentage of Tmax
prod, set on screen Gea03 (default 70%) the water level is above the high
level for a time equal to “Max Hlev time”, atomised water production stops
and warning EL is generated. The wait procedure then starts, after which
the controller will attempt to restart production. Warning EL is reset at the
end of a production cycle that ends correctly. Alarm EL is also generated
during standby if an abnormal water level is measured (the water level
diff ers from the level measured when switching to standby, for a time
equal to Max Hlev time).
Tmin prod: minimum atomised water production time (driver active)
during which the low level sensor must not be activated.
Tmin prod sets a minimum production time (default 1 minute). If the
production cycle lasts less than this time, the drain solenoid valve may
not be tight or the fi ll solenoid valve fl ow-rate may be too low. The
controller, in this case, activates the following procedures:
1. at the end of the fi rst cycle, ending after less than Tmin prod, the Refi ll
time is increased (50% more than Refi ll time) and the drain solenoid
valve is powered at a higher voltage to try and increase tightness;
2. at the end of the second cycle, ending after less than Tmin prod,
the water refi ll time is further increased (100% more than Refi ll time)
and chattering* of the drain solenoid valve is activated during the fi rst
automatic washing cycle;
3. at the end of the third cycle, ending after less than Tmin prod, the
water refi ll time is further increased (150% more than Refi ll time) and
a washing cycle is performed, including chattering* as activated in
the previous step. Warning Ed will also be generated.
4. following the last stage, a new production cycle will be performed.
If the cause of the error persists, the controller will start the procedure
from the beginning again, until it a full cycle is completed within the
defi ned times. Any warnings will also be reset.
*Chattering: series of rapid opening/closing cycles of the drain solenoid valve,
aimed at removing any residues (scale, dust, etc.) that prevent it from closing
correctly.

Refi ll time: time the fi ll solenoid valve is kept open for, after the control
level (intermediate) has been reached during atomised water production.
Tmax refi ll: maximum time the drivers remain active for during a water
refi lling cycle, after the level sensor has measured the low water level
during atomised water production.
The piezoelectric transducers, by nature, if operated without water,
will be quickly damaged until failing. To prevent this from happening,
the controller ensures, via the level sensor, that even in the event of
malfunctions the transducers are never activated without water present.
When starting with an empty tank, the transducers are only activated
when the low level is measured and, subsequently, the “Refi ll time” has
elapsed. During refi lling when the unit is operating, that is, after the low
level has fallen due to atomised water consumption with consequent
activation of the fi ll solenoid valve, if the level is not restored before the
“Tmax refi ll” time, the transducers are switched off , while the fi ll cycle
continues until:
1) the level has been restored and the “Refi ll time” has elapsed. The
transducers are then reactivated
2) on activation of the fi ll valve, the time set for Tmax fi ll must elapse.
Then the wait procedure will be activated, as described previously.
If, on the other hand, the level is correctly restored within the “Tmax refi ll”
time, the transducers remain on and the fi ll cycle continues until the end
of the Refi ll time.

Low lev delay: low level fi ltering time for activating the fi ll cycle.
The fl oat sensor must remain active for the time set by Low lev delay
before the fi ll cycle (Refi ll) or the complete emptying timer (Empty Drain)
is activated).
Unit offl ine alarm times
Remote board offl ine time: time after which the remote unit is deactivated
(standby) if there is no serial connection with the control panel.
The remote unit checks communication status with the “Master” panel,
and if for some reason there is no communication for the time set for
the parameter, the unit goes into “safety” mode, that is, atomised water
production is stopped and the drain cycle is activated.
Main board offl ine time: time after which the control panel generates
the “Remote unit offl ine” alarm if no serial communication is detected.
If the “Main board offl ine time” elapses, and the control panel continues
to not receive a response, the “Remote unit offl ine” alarm is activated. In
this status, atomised water production can no longer be activated.
