MANUALE D’USO – USER MANUAL
GENERALITY
The family of Pego EASYSTEAM sunk-electrode humidifiers is the latest conception on the
humidifiers market and can be considered the most complete for use type and easy maintenance.
The line includes humidifiers with 3KG/h and 6KG/h capacity with single-phase electric power
supply, 6KG/h, 12KG/h, 24KG/h, 48KG/h with three-phase+neutral electric power supply; all able
to work in ON/OFF mode, proportional mode with integrated humidostat and 4-20mA or 0-10V
probe, proportional mode with outdoor 0-10V signal, in ON/OFF mode from integrated thermostat.
The EASYSTEAM humidifiers are provided with a microprocessor software enabling the widest
programming for a fully customised use and a completely automatic functioning.
In fact, it is possible to set the maximum steam supply capacity, intermediate capacity values in
percentage, discharge frequency for disturbance, water discharge for non-use.
The EASYSTEAM line is also provided with a display for real time viewing of the humidity in the
premises to be treated; the current absorbed by the electrodes, the hours of work, various alarms,
water charging and discharging as well as all easily settable programming parameters.
An acoustic alarm (buzzer) is present in the EASYSTEAM humidifiers that warns the user of any
anomalies; the internal software is able to evaluate the seriousness of the anomaly, blocking the
machine or continuing the steam supply.
The strength of the EASYSTEAM line is the simplicity with which the cylinder is replaced when
normal wear makes it necessary.

MANUALE D’USO – USER MANUAL
FUNCTIONING PRINCIPLE
The EASYSTEAM series sunk-electrode humidifiers use the conductivity of potable water to
produce steam by boiling.
A current is generated between the electrodes sunk in appropriate cylinder, that heats the water to
boiling point.
Current intensity (expressed in amperes) varies according to the quantity of water in cylinder that is
in contact with the electrodes surfaces and the conductivity of the water itself.
The electronics in the humidifier, via an amperometric transformer, measures current intensity and
controls the water charge valve to raise the water level or the discharge pump to lower it. This
system is fully automatic.
Combined use of the microprocessor and a humidity sensor also makes it possible to set
proportional functioning, optimising water and electricity consumption according to required
humidity levels.
In addition to ensuring functioning during steam output, the discharge pump also guarantees
draining the cylinder completely when the unit has been idle for a set time: this prevents forming
and depositing of limescale or other particles created during the boiling process.
The EASYSTEAM series humidifiers are fully automatic and require only replacement of the
cylinder when the electrodes are worn.
The layout below illustrates the functioning principle.
1.3
Page 8 Rev. 05-12
MANUALE D’USO – USER MANUAL
The supplied steam is managed proportionally upon steam output request that the
electronic control calculates depending on the chosen functioning among the eight available,
described in chap. 2.4. The
minimum steam supply is fixed
at 20% and is managed with an
activation hysteresis; the
maximum supply had in
correspondence with a
maximum requested output,
corresponds to the percentage
set in the first level variable
(Pr). If, for example, on an
ES6 producing 6Kg/h of Pr
steam 100% is set, maximum
supply will be 6Kg/h; but if Pr
is reduced to 50%, maximum
supply will be 3Kg/h.
To ensure correct humidifier functioning, use only mains potable water; this because it
is free from any toxic content and is compatible with the conductivity range
needed for optimal humidifier functioning. However, in some geographical areas mains water may
be unsuitable for optimal functioning due to very low or too high or too aggressive conductivity; the
below is a summary table of the parameters required for correct humidifier functioning.

* Water conductivity is always expressed at 20° C; bear in mind that conductivity decreases as
water temperature drops and so water may not be very conductive during winter when mains water
is particularly cold.
To overcome this problem, decrease the produced steam percentage described
in chapter 3, PROGRAMMING, in this manual.
Do not supply the humidifier with well water or treated with osmosis purifiers,
demineralising or softeners or taken from cooling circuits.

ELECTRIC CONNECTIONS
Connect the electric power supply to the humidifier terminal box bringing 230V voltage to
clamps R and N for single-phase models, or 400V voltage + neutral to the RST and N
clamps for the three-phase models.
It is compulsory to connect the yellow/green clamp with initial PE to the earth system of the electric
mains. If required, check earth system efficiency.
Leave jump in clamps 60 and 61 of the terminal box or, if required, replace it with a normally
closed emergency contact.
Clamps 62 and 63 of the terminal box are arranged for fan unit power supply; in case of unit
installation, consult the use manual attached thereto.
ES AND OEM SERIES SENSORS AND CONTROL SIGNALS CONNECTIONS
The humidifier envisions eight different functioning mode settable from S9 software variable
described in chapter 3.5 and from specific electric connections.
Also necessary is the enabling to In1 digital input clamps 24 and 25 on the MasterHUM2
microprocessor board for all functioning mode (enabling = closed contact between clamps 24 and
25). Without enabling, the display alternates the OFF writing with normal displaying.
Below are the specific connections for every functioning mode.
If wanting to connect the humidifier with humidity probes not supplied by PEGO s.r.l.,
contact the after-sales assistance centre to verify hardware compatibility of the probe
with the humidifier.
- [S9=0] ON/OFF Functioning:
This type of functioning envisions steam output in 2 ways only: no output or maximum output.
The consent is usually given by a potential free contact coming from an electrical panel which,
in turn, is controlled by a humidostat. Set the second level variable S9=0 and connect the
consent to clamps 24 and 25 of the Master HUM2 board (Enabling present with closed contact).

- [S9=1] PROPORTIONAL functioning with 4-20mA ambient humidity probe
(INTEGRATED HUMIDOSTAT):
This type of functioning envisions proportional steam output; the humidifier will automatically
regulate the steam output based on the request in ambient depending on set set. Consent is given
by a 4-20mA (0-100%RH) humidity probe that, as well as regulate steam output, enables
displaying relative humidity in ambient, directly on humidifier display. Set the second level
variable S9=1 and connect signal 4-20mA of the humidity probe to clamps 14 and 15; in
particular, connect the RH signal to clamp 14, connect +V to clamp 15.

-
The Bp proportional band is the percentage value of the humidity around the set point; within
this value the humidifier works proportionally. Example: if the proportional band is set on
default value 10% (-5% / +5% set point value) and humidity is set at 50%, below 45% the
humidifier will work at 100% of steam output; above 55%, the humidifier will not produce
steam. Between 45% and 55%, the humidifier will optimally regulate steam output.
- [S9=2] PROPORTIONAL functioning with 0-10Vdc signal of reference:
This type of functioning envisions steam output proportionally to 0-10Vdc signal of reference.
Example: a 6Vdc signal of reference ensures the humidifier produced 60% of steam output
referred to Pr software variable. So if Pr= 70%, steam output will be 42%. Set the second level
variable S9=2 and connect signal of reference 0-10V to clamps 16 and 17; in particular, connect
VRH (0-10Vdc probe output) to clamp 16, and GND mass to clamp 17.
