Drain due to inactivity
If the humidi er not used for an extended period, the water in the
cylinder should be drained to prevent stagnation and hygiene risks. To
set this function, from the “Maint SW” submenu press:
ENTER to access the “Additional features” screen;
ENTER to move the cursor to the “Inactivity drain” parameter;
UP or DOWN to enable (YES, default) disable (NO) the function;
ENTER until moving the cursor to the start of the screen;
DOWN to access the second “Additional features” screen;
ENTER to move the cursor to the “Inactivity drain” parameter ;
UP or DOWN to modify the number of days without steam production
after which the automatic drain cycle is activated (default 3 days);
ENTER to con rm ;
ESC repeatedly to return to the “Main” screen.
Periodical drain (for water rich in residues)
Operation with water containing considerable traces of humus, lime,
debris, may a ect the e ciency and the operation of the humidi er. In
these cases a periodical complete drain cycle of the water contained in
the cylinders may be useful in helping to discharge the sediments. To
automatically set the periodical drain cycle, from the “Maint SW” submenu
press:
ENTER to access the “Additional features” screen;
ENTER to move the cursor to the “Periodic  ushing” parameter;
UP or DOWN to enable (YES) disable (NO, default) the function;
ENTER to move the cursor to the last “Periodic  ushing” parameter;
UP or DOWN to set the number of hours between one drain cycle and
the next (default 24 h);
ESC repeatedly to return to the “Main” screen.
Drain without power
The evaporation of the water causes an accumulation of salts inside
the cylinders, leading to an increase in conductivity. The humidi er
thus automatically runs a short drain cycle (drain to dilute) to lower the
conductivity.
During the drain cycle the contactor is open, so that the water drained
does not conduct current (in this short period, in fact, steam production
is momentarily stopped). To perform the drain cycle with the contactor
closed, from the “Maint SW” submenu press: :
ENTER to access the “Additional features” screen;
ENTER to move the cursor to the “Unpowered drain” parameter;
UP or DOWN to disable (NO) or enable (YES, default) the function;
ESC repeatedly to return to the “Main” screen.
Disabling the “Cylinder pre-exhaustion” and “Cylinder
exhaustion” alarms
To disable these two alarm signals, press:
ENTER to access the “Additional features” screen;
ENTER to move the cursor to the “Cylinder warning” parameter;
UP or DOWN to disable (NO) or enable (YES, default) the function;
ENTER to con rm;
ESC repeatedly to return to the “Main” screen.
“Delay stop steam” function
Used to delay the interruption of steam production after a steam o
request.
To set the delay time (maximum 120 seconds), from the “Maint SW”
submenu press:
ENTER to enter the second “Additional features” screen;
ENTER to move the cursor to the “force cond.” parameter;
UP or DOWN to set the conductivity value (up to 2000 μS/cm);
ENTER to con rm;
ESC repeatedly to return to the “Main” screen.
Conductivity of the supply water
Forced conductivity setting
To enable the forced conductivity setting, from the “Maint SW” submenu
press:
ENTER to enter the second “Additional features” screen;
ENTER to move the cursor to the “force cond.” parameter;

UP or DOWN to set the conductivity value (up to 2000 μS/cm);
ENTER to con rm;
ESC repeatedly to return to the “Main” screen.
High conductivity alarms
To determine the high conductivity alarm thresholds, from the “Maint SW”
menu press:
ENTER until reaching the “Thresholds conduct.” screen;
ENTER to move the cursor to the “Warning” parameter (1,000 μS/cm);
UP or DOWN to set the conductivity pre-alarm value (signal only);
ENTER to con rm and set the conductivity alarm value (1250 μS/cm;
signal and stop steam production);
ENTER to con rm;
ESC repeatedly to return to the “Main” screen.
Note The alarms are not activated if the forced conductivity
setting is enabled.
Duration and frequency of the drain to dilute cycle
Based on the type of water used, the duration and the frequency of the
automatic drain cycle can be set as a percentage of the rated value.
From the “Maint SW” submenu press:
ENTER until reaching the “Thresholds conduct.” screen;
ENTER to move the cursor to the “Drain duration” parameter (default
100%);
UP or DOWN to set the percentage of the duration;
ENTER to con rm and set the percentage of the frequency between
one drain cycle and the next (default: 100%);
ENTER to con rm;
ESC repeatedly to return to the “Main” screen.
7.9 Copying the settings (backup)
This function is used to save a copy of the settings (e.g.: names of the
essences, fan operation, time band settings,...). The copy saved can
be restored when needed, for example when errors are made in the
settings.
A copy of the settings should be made for each required con guration.
Creating a copy of the settings
From the “Maint SW” submenu press:
ENTER to con rm;
DOWN until displaying the “Backup” screen;
ENTER to move the cursor to YES/NO;
UP or DOWN to set YES;
ENTER to con rm;
ESC repeatedly to return to the “Main” screen.
Restoring the last copy
From the “Maint SW” submenu press:
ENTER to con rm;
DOWN until displaying the “Restore” screen;
ENTER to move the cursor to the YES/NO;
UP or DOWN to set YES;
ENTER to con rm.
ESC repeatedly to return to the “Main” screen.
Important: All the changes made since the last copy was saved
will be lost.
