6.1
Start-up
After having connected power using the main disconnect switch (ON), switch the appliance on by
moving the switch on the front panel to “ON”. The activation sequence will start, which includes an initial
phase, an autotest phase and finally actual operation. Each step in the activation sequence is identified by
a different display.

1. STARTING THE APPLICATION PROGRAM THE FIRST TIME
The “gaSteam” humidifier logo is displayed. When starting the first time, the menu language needs to be
selected:
English
Italiano
Deutsch
Français
Español
Select the desired language and confirm. This screen is displayed for 60 seconds.
2. FIRST START-UP (WIZARD)
When starting the first time, a wizard is provided to quickly set the main unit parameters. The wizard
comprises ten steps (some of which may not be displayed, if not necessary):
1/10 - model (only if the replacement controller is not configured): select and set the parameters relating
to the model (size, voltage,…);
2/10 - water hardness: auto or user-defined. If choosing “auto”, the controller automatically sets the water
hardness, based on feedwater conductivity;
3/10 - manual water hardness setting. The possible options are:
l Demineralised, maintenance at 3000h (hours)
l 0-10°f, maintenance at 3000h (hours)
l 10-20°f, maintenance at 1500h (hours)
l 20-30°f, maintenance at 1000h (hours)
l 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 probe 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-defined. If choosing “auto”, the controller automatically
sets the number of evaporation cycles that must occur between two consecutive drain to dilute cycles.
This setting is based on the feedwater conductivity read by the conductivity meter, thus reducing the use
of water, 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 unit status shown as “AUTOTEST”.
