C
ommissioning
After having connected power using the main disconnect switch (ON), switch the appliance on by moving the switch on the front panel (1 -
Fig. 11.a) to “ON”. The activation sequence will start, which includes an initial phase, an autotest phase and fi nally actual operation. Each step in
the activation sequence is identifi ed by a diff erent display.

ctivation sequence
1. APPLICATION PROGRAM RUN THE FIRST TIME
The humidifi er logo (gaSteam) is displayed. When starting the fi rst time, the
menu language needs to be selected: English, Italiano, Deutsch, Français, Español.
Select the desired language and confi rm. This screen is displayed for 60 seconds.
2. WIZARD
When starting the fi rst time, a wizard is provided to quickly set the main humidifi er parameters. The wizard com-
prises ten steps (some of which may not be displayed, if not necessary):
1/10
model (only if the replacement controller is not confi gured): select and set the parameters relating to the model
(size, voltage,…);
2/10
water hardness: auto or user-defi ned. If selecting “auto”, the controller automatically sets the hardness
of the water, based on the conductivity reading;
3/10
manual water hardness setting. The possible options are:
• Demineralised, maintenance at 3000h (hours) • 0-10°f, maintenance at 3000h (hours)
• 10-20°f, maintenance at 1500h (hours) • 20-30°f, maintenance at 1000h (hours)
• 30-40°f, maintenance at 800h (hours);
4/10
control type: external On/Off signal, proportional to external signal with limit probe, proportional to
external signal, one humidity probe, one temperature probe, one humidity probe and limit probe, one
temperature and limit probe, two temperature probes (average), two humidity probes (average);
5/10
select the main room probe type:
0-1V (active), 0-10V (active), 2-10V (active), 0-20 mA (active), 4-20 (active), NTC (passive);
6/10
select the limit probe type: 0-1V (active), 0-10V (active), 2-10V (active), 0-20 mA (active), 4-20 (active), NTC (passive);
7/10
set the limits for active probes.
• Room min (%): set the minimum relative humidity limit rH% for the main probe;
• Room max (%): set the maximum relative humidity limit rH% for the main probe;
• Limit min (%): set the minimum relative humidity limit rH% for the limit probe;
• Limit max (%): set the maximum relative humidity limit rH% for the limit probe;
8/10
set the drain to dilute cycles: auto or user-defi ned. If selecting “auto”, the controller automatically sets
the number of evaporation cycles that must occur between two consecutive drain to dilute cycles. The selection
is made by reading the inlet water conductivity using the conductivity meter, thus reducing water usage,
reducing maintenance and extending boiler life;
9/10
manual drain to dilute cycle setting. Enter the number of evaporation cycles before
forcing a dilution cycle.
10/10
date and time setting. At the end of the guided procedure, a message prompts whether to show the wizard again
when next starting? Yes/No
3. AUTOTEST
PROCEDURE
Indicated on the display by the humidifi er status shown as “AUTOTEST”. Whenever the humidifi er is
started (switch moved from OFF to ON), an autotest procedure is run by default to check operation of the level sensor and
the appliance as a whole. The autotest procedure involves a water fi ll cycle to above the high level (green LED), followed
by a drain cycle until below the minimum level (red LED). The procedure then refi lls the unit with water in order to restart
production (if required).
Notice:
all the screens in the wizard (except for the language selection screen) remain on the display until the user
enters the settings.
4. OPERATION
The humidifi er starts operating and the standard display is shown. If an alarm is active, the corresponding icon
(bell) comes on red, see the chapter “Alarms” for the complete list and description.
Notice:
model selection and confi guration (only for non-confi gured replacement controllers). If needing to replace the
controller only (controller replacement part number UGKA0D0040), the fi rst time the controller is powered on, the model
will need to be set (capacity, power supply and version).
