The green LED remains on for the entire time the machine is on, irrespective of the operating status.
The flashing sequence consists of the following operations:
1. power connected: the yellow and red LEDs remain off for 1 second;
2. initialisation: the yellow and red LEDs flash a number of times to indicate the version of the program that the board is
configured with; this occurs once each time the machine is started;
a.
first the yellow LED - the number of flashes indicates the tens (0=no flash);
b.
then the red LED - the number of flashes indicates the units (0=no flash);
H[DPSOH
version 1.1: 1 flash of the yellow LED, then 1 flash of the red LED;
c.
once the sequence of flashes corresponding to the unit is completed, the LEDs are turned of for 3 seconds, then
remain off for 3 seconds and, finally, the normal operational behaviour starts.
3. operation: the humidifier starts operation; the yellow LED indicates that production is in progress, as shown by the
following table:

: the transient production is signalled by short flashes: on and off twice in 1 second; each sequence of flashes repeats
continuously and, between one sequence and the next one, the yellow LED stays off for 3 seconds

In the event an anomaly or alarm, the red LED starts to flash. The signal is composed of a sequence of the flashes followed

The level of humidity in an environment can be controlled using a special ON/OFF regulator (humidistat). This device has
the task of measuring the level of ambient humidity, comparing it against a settable reference value and requesting, when
necessary, the start of steam production by closing an electrical contact connected to the machine, as described in
$X[LOLDU\FRQQHFWLRQV
.
When the humidity measured reaches the reference value, the humidistat will stop production.

During seasonal shut-down or alternatively shut-down for maintenance of the electrical and/or hydraulic parts, the
humidifier should be placed out-of-service.
