USER MANUAL
LEVEL 1 PROGRAMMING
1. Level 1 programming allows the user to modify 2 important parameters, the proportional band
Bp and the steam production percentage Pr.
VAR. MEANING VALUES
DEFAULT
all models
Pr Steam production percentage
20 ÷ 100 % 100 %
Bp
Proportional band
(not used on the ON/OFF versions)
1 ÷ 20 Rh% 10 %
StC
Max humidity set point in duct Outgoing set point value humidifier will
switch off and start functioning again when humidity into duct will go below
the value StC – r0 adding t1 time, following the logic sent by 0-10V signal or
by ambient humidity sensor

The proportional band Bp is a percentage humidity value around the set point; within this
band the humidifier works in proportional mode.
Example: if proportional mode is set to the default value of 10% (-5% / +5% with reference to the
set point) and humidity is set to 50%, then below 45% the humidifier works at 100% steam output;
above 55% the humidifier does not produce any steam at all. Between 45 and 55% the humidifier
will optimise steam output.
The steam percentage value Pr is the value the humidifier is able to reach at maximum output. For
example, leaving the setting at 100% on an ES6 rated at 6 Kg/h will give 6 Kg/h of steam output; if
the Pr setting is reduced to 50% the humidifier will produce 3 Kg/h at most.
The Pr variable is highly useful where water conductivity is poor and when you need to
make the most of the cylinder when it is nearing replacement; for further information
consult chapter 6 TROUBLESHOOTING of this manual at page 25.
The humidity duct set point (stC) is an humidity limit into duct. If the humidity in duct is higher the
humidifier stop steam production and restart when the duct humidity is less than StC-r0. Consider
an additional time delay (t1 on second programming level) before the steam production start again.
To gain access to the Level 1 programming menu proceed as follows:
- Press the (t) and (u) keys simultaneously and keep them pressed for a few seconds until the
first programming variable appears on the display.
- Release the (t) and (u) keys.
- Select the variable to be modified using the (t) or (u) key.
- When the variable has been selected it is possible:
- to display the setting by pressing SET
- to modify the setting by pressing the SET key and the(t) or (u) keys.
- When configuration values have been set you can exit the menu by pressing the (t) and (u)
keys simultaneously for a few seconds until the parameter shown before programming was
accessed (e.g. steam production or absorbed current) reappears.
- The new settings are saved automatically when you exit the configuration menu.
