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 fill solenoid valve flow-rate may be too low. The
controller, in this case, activates the following procedures:
1. at the end of the first cycle, ending after less than Tmin prod, the Refill
time is increased (50% more than Refill time);
2. at the end of the second cycle, ending after less than Tmin prod,
the water refill time is further increased (100% more than Refill time)
and chattering* of the drain solenoid valve is activated during the first
automatic washing cycle;
3. at the end of the third cycle, ending after less than Tmin prod, the
water refill time is further increased (150% more than Refill 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
defined 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.

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 “Refill time” has
elapsed. During refilling when the unit is operating, that is, after the low
level has fallen due to atomised water consumption with consequent
activation of the fill solenoid valve, if the level is not restored before the
“Tmax refill” time, the transducers are switched off, while the fill cycle
continues until:
1) the level has been restored and the “Refill time” has elapsed. The
transducers are then reactivated
2) on activation of the fill valve, the time set for Tmax fill 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 refill”
time, the transducers remain on and the fill cycle continues until the end
of the Refill time.

Low lev delay: low level filtering time for activating the fill cycle.
The float sensor must remain active for the time set by Low lev delay
before the fill cycle (Refill) or the complete emptying timer (Empty Drain)
is activated).
7.7.3 Unit offline alarm times
Remote board oine 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 “Main” 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 offline time: time after which the control panel generates
the “Remote unit offline” alarm if no serial communication is detected.
If the “Main board offline time” elapses, and the control panel continues
to not receive a response, the “Remote unit offline” alarm is activated. In
this status, atomised water production can no longer be activated.
