5. PREPARING FOR OPERATION
5.1 Preliminary checks
Before starting the humidifi er, check that:
•
the water and electrical connections are made and the steam
distribution system is confi gured according to the instructions
contained herein;
•
the shut-off tap for water into the humidifi er is open;
•
the power fuses are installed and intact;
•
terminals M2.7 and M2.8 are connected by jumper or connected to the
remote ON/OFF contact, and that the latter is closed;
•
the probes or the external control device are correctly connected (and
that the earth of these devices is electrically connected to the earth of
the main control board);
•
the steam outlet pipe is not choked;
•
in the event of ducted humidifi cation, the operation of the humidifi er
is slave to the operation of the air fan (replacing or in series with the
remote ON/OFF contact);
•
the distributor condensate return pipe is installed and free;
•
the drain pipe is correctly connected and free.
Important: before starting the humidifi er, check that it is in
perfect condition, that there are no water leaks and that the
electrical parts are dry.
6. START-UP AND USER INTERFACE
•
6/9 – select the limit probe type: 0-1V (active), 0-10V (active), 2-10V
(active), 0-20 mA (active), 4-20 (active), NTC (passive);
•
7/9 - set the limits for the 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;
•
8/9 - set the drain to dilute cycles: auto or user-defi ned. 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 cylinder life;
•
9/9 - manual drain to dilute cycle setting. Enter the number of
evaporation cycles before forcing a dilution cycle.
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”.
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).
Note : in the event of malfunctions, the contactor is deactivated and
the corresponding alarm is shown.
Note : 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 comes on red, see chapter 13
“Alarm table” for the complete list and description.
Once having completed the operations listed in chapter 5. “Preparing for
operation”, the humidifi er can be started.
6.1 Start-up
After having closed the disconnect switch on
the humidifi er power line, switch the appliance
on by moving the switch on the front panel
to I, “ON”. The activation sequence will start,
which includes an initial phase, an autotest
phase and fi nally actual operation. Each phase
in the activation sequence is identifi ed by a
diff erent display.

1. STARTING THE APPLICATION THE FIRST TIME
The “heaterSteam” humidifi er logo is displayed. When starting the fi rst
time (commissioning), the menu language needs to be selected:
1. English 3. Deutsch 5. Español 7. Chinese
2. Italiano 4. Francais 6. Russian 8. Czech
Press UP/Down to select the number corresponding to the desired
language and press ENTER to confi rm. This screen is displayed for 60
seconds.
2. FIRST START-UP (WIZARD)
When starting the fi rst time, a wizard is displayed to quickly set the main
unit parameters. The wizard comprises nine steps (some of which may
not be displayed, if not necessary):
•
1/9 - model (only if the replacement controller is not confi gured):
select and set the parameters relating to the model (size, voltage,…);
•
2/9 - water hardness: auto or user-defi ned. If choosing “auto”, the
controller automatically sets the water hardness, based on feedwater
conductivity;
•
3/9 - manual water hardness setting. The possible options are:
Demineralised, maintenance at 3000h (hours)
1.
0-10°F, maintenance at 3000h (hours)
2.
10-20°F, maintenance at 1500h (hours)
3. 20-30°F, maintenance at 1000h (hours)
4.
30-40°F, maintenance at 800h (hours);
•
4/9 - 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);
•
5/9 – select the main room probe type: 0-1V (active), 0-10V (active),
2-10V (active), 0-20 mA (active), 4-20 (active), NTC (passive);
