10.1.5 Manual drain command
In the first 5 seconds from the start-up of the unit (during the autotest sequence: see Fig. 10.1.2.2), press the
at the same time. After 2 seconds the drain electrovalve is activated, until the buttons are released.
When the buttons are released, the command can be repeated within 5 seconds, otherwise the humidifier must be switched off
and on again.
10.1.6 Setting the steam production
The average steam production can be adjusted using a pseudo-modulating action, with the cyclical activation of the remote-
control switch and a programmable operating interval divided into four steps: 30%; 50%; 75%; 100% of the total time (this
mode can not be applied in severe operating conditions and without consequences on the noise level caused by the frequent
activation of the remote-control switch). To do this, use the
10.2 Type H or T control module, numeric LED display, modulating action

n. description
1 button for accessing the more frequently used functional parameters (codes Px, dx); it also acts as a reset button for the alarm relay (if
the alarm is no longer active)
2 displays the unit of measure of the value shown on the display;
pressed for 2 seconds accesses the display/programming of the Set Point;
if pressed together with button 1 for 5 seconds, accesses the routine for programming the configuration parameters
3 while pressed, displays the value measured by the main probe (with ON/OFF control nothing is displayed); in programming mode acts
as a button to decrease the value or scroll back to the previous parameter
4 while pressed, displays the value measured by the compensation probe (only if featured);
in programming mode acts as a button to increase the value or scroll to the next parameter
5 2 ½ digit display to indicate the numeric values and codes of any active alarms;
during programming shows the codes of the parameters and their values
6 LED representing the decimal point
7 LED for multiplying by one thousand the value indicated on the display
8 LED indicating the activation of the dehumidification relay
9 LED flashing indicating alarm relay activated
10 LED indicating current steam production;
if flashing indicates the pre-heating phase
11 LED indicating operation of the fill electrovalve
12 LED indicating operation of the drain electrovalve
10.2.2 Start-up sequence
On starting-up the humidifier, the start-up sequence occurs, signalled by the illumination of the LEDs, as described below.
1 - POWER ON
In this phase, lasting around a
second, all the LEDs on the
display are illuminated.
Fig. 10.2.2.1
In the event of an active alarm, the LED next to the ALARM marking is illuminated and the display shows the relative code.

The humidifier begins operation, and the control module indicates
(see REGULATION PRINCIPLES) one of the following options:
steam production (in %) with slave regulation;
the measurement of the main transducer with autonomous
regulation;
when the humidifier is disabled, the 3 segments - - - are illuminated in
sequence.
