connect the flexible pipe with the non-return valve (supplid - code
FWHDCV0003), to avoid the water inside the humidifier not making
contact with the one in the mains;
install a mechanical filter to retain any solid impurities (connect
downstream with respect to the tap.
connect a section of pipe for draining (resistant to temperatures of
100 ° C (212 ° F)) and with a minimum internal diameter of 40 mm
(1.6 in) for models UR002-UR013 and 50 mm (2 in), for models UR020
UR080;
provide a funnel to ensure continuity interruption in the drain piping;
connect a syphon to prevent the return of odours;
for models UR020...UR080: connect a drain pipe from the tank to
the bottom of the humidifier (this can run into the funnel used for
draining).
for drain tempering versions, water temperature will be 60 °C, so input
temperature is 25 °C guaranteed.

Caution:
• once the installation is complete, flush the supply pipe for about
30 minutes by carrying water directly in the drain and without
introducing it into the humidifier. This will eliminate any waste or
processing residues that could clog the inlet valve and/or cause foam
when boiling water;
• the drain pipe must run vertically downwards at least 30 cm (figure) to
prevent the return of steam.

2.1 Supply water
The supply water for the electric resistance humidifier must not be
corrosive, must not emit bad odours, and must not contain too much
lime to avoid excessive deposits. The water, supplied from mains
of drinking water or demineralised water, must have the following
characteristics:

°C; R180 ≈0,65 * σR , 20 °C;
(2) Not lower than 200% the content of chloride in mg/l Cl- ;
(3) Not lower than 300% the content of chloride in mg/l Cl- ;
(4) It could be necessary to intervene on the drain rate to avoid a concentration
in the boiling water higher than 300 mg/l Cl-.
Attention:treating the water with water softeners or
polyphosphates dispensers is not allowed; it allows for reduced
maintenance but favors the concentration of dissolved salts in the
water in the cylinder, leading to potential corrosion to the heating
elements and possible operation irregularities due to the formation of
foam. Should this be impossible to avoid, it requires dilution with
ordinary mains water in such a quantity as to guarantee at least 60% of
its initial hardness value, and not less than 5°f. Water treatment with
reverse osmosis demineralisers is allowed.
Not recommended:
1. the use of well water, industrial water or water from cooling circuits
and, in general, water which may be chemically or bacteriologically
contaminated;
2. the addition to the water of disinfectants or anticorrosion
compounds, as these may cause irritation.
Note: no relationship can be proven between water hardness
and conductivity; nonetheless, as an indication only, water with a
hardness of 40°f should have a conductivity of approximately 900-1000
mS/cm a 20 °C.
2.2 Drain water
• contains the same substances dissolved in the supply water, but in
larger amounts;
• it can reach a temperature of 100 °C (212° F);
• it is not toxic and can be drained in the white waters collection
system.
3. for drain tempering versions, water temperature will be 60 °C, so input
temperature is 25 °C guaranteed.
Attention: completely demineralised water is aggressive. For
connection to a water system with fully demineralized water use
only installation items made of plastic resistant to chemicals (eg.
Polypropylene) or stainless steel.

• set parameter A0=1 to enable the modulating action (see chapter 7)
and parameter A2 according to the signal chosen (0...1V, 0...10V, 2...10V,
0...20mA, 4...20mA).
4.4 Steam production command signals
Attention: follow this sequence of steps in order to avoid
damaging the control board:
1. program the controller and turn it off ;
2. make the electrical connections;
3. switch the controller on.
The humidifier is fitted with solid-state relays, therefore its capacity
can vary from zero to 100% depending on the control requirements.
In addition, it can be connected by means of RS485 serial to a remote
supervisor. Depending on the type of signal used you can obtain
different types of enabling and/or management of the steam production
(ON/OFF or modulating). Production enabling is achieved by electrically
connecting the terminals 7I and 8I (jumper).

4.5 Control with humidity probes
Attention: prior to connecting the signal you must set the
parameters A0-A2-A6
The main control board, connected to an environment humidity
control probe, adjusts the steam production according to the humidity
measured. You can connect a second humidity probe on the outlet: in
this configuration, typical of air treatment plants, the main control board
continues to adjust the steam production according to humidity, which
depends however on the value of the relative humidity measured in the
outlet pipe.
HUMIDISTAT and REMOTE CONTACT (on/off )
• connect the inputs 4l and 5l (production command) to a humidistat;
• connect the inputs 7l, 8l (enabling) to a remote contact (e.g.: switch,

In addition, the maximum and minimum values must be programmed
for the signal (parameters A3 and A4 for the room probe; A7 and A8 for
the outlet probe).
The probes can be powered at the following voltages:
• 12 V stabilised at terminal 4I;
• 32 Vdc from the rectifying of 24 Vac at terminal 3I.
The control signals must be connected:
• for the control probe HP (TT in the case of controls for steam baths) to
terminal 5I, whose reference ground (GND) is terminal 6I;
• for the limiting probe HLP, to terminal 1I, whose reference ground

Control with temperature probes
The control of this appliance features autonomous internal control, and is
connected to a temperature probe TT (Fig. 4.i).
This performs complete control according to the temperature measured
inside the environment being controlled.
Fig. 4 s shows the connection of the CAREL probe type ASET030001, with
measurement range -30T90 °C (Fig.4.s). The CAREL recommended probes
have a 0 to 1V output. The control signal must be connected to terminal
5I, whose reference (GND) is represented by terminal 6I. The control can
be connected to non-CAREL active probes.
The humidifier’s control module features a voltage-free switching contact
for the remote signalling of the presence of one or more anomalous
events or alarms. Connection to the alarm contact (250 Vac; maximum
load: 8 A resistive - 2 A inductive) is made using the removable terminal
block H, as per Fig. 4.t.
Set up for remote indication of the presence of one or more alarms
(terminals 1H, 2H, 3H).

The following conditions represent correct electrical connection:
1. the network voltage of the appliance corresponds to the voltage on
the specification plate;
2. the fuses installed are suitable for the line and the voltage of the
power supply;
3. humidifier to be disconnected;
4. the humidifier has been grounded correctly;
5. the power cable is fastened to the tear-proof cable clamp;
6. terminals 7I and 8I are connected by jumper or an enabling contact;
7. if the appliance is controlled by an external regulator, the ground of
the signal is electrically connected to the ground of the controller’.
Fig. 4.s
Attention: prior to connecting the signal you must set the
parameters A0-A2-A6
Using different brand probes
Different brand probes can be used, with output signals selected, by
programming the parameter A2, (see tab. 4.a) from the following:
• voltage signal: 0 to 1 Vdc; 0 to 10 Vdc; 2 to 10 Vdc;
• current signal: 0 to 20 mA; 4 to 20 mA.

The control board of the humidifier can be connected serially RS485 with

Fig. 5.a
The transmission line can reach a maximum distance of 1000 metres
between the two most distant points.
Attention: for the RS485 connections in industrial (CEI61000-6-2)
environment, use shielded cable (with shield connected to PE just
on one side, either the terminal or the controller side) with maximum
shielded cable length of 30 m.
Use shielded twisted pair cable (AWG26), the 485 input stage impedance
is 1/8 unit-load (96kOhm). RS485 cables must lay in separate conduits
from the power cables.
6. PREPARING FOR OPERATION
Attention: upon installation completion, drain the supply pipe for
around 30 minutes by passing water directly through the pipe
and without introducing it into the humidifier. This will allow the
elimination of any scoria and processing residues that may cause the
formation of foam during the boiling.
Attention: before starting the humidifier, check that it is in
perfect condition, that there are no water leaks and that the
electrical parts are dry. Do not supply voltage if the humidifier is damaged
or even partially wet!
6.1 Preliminary checks
6.2 Removing the heating element centring
spring (only for three-phase models)
Before starting the humidifier, check that:
• the water and electrical connections are made and the steam
distribution system is configured according to the instructions
contained herein;
• the shut-off tap for water into the humidifier is open;
• the power fuses are installed and in tact;
• terminals 7I and 8I 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 ground of these devices is electrically connected to the
ground of the main control board);
• the steam outlet pipe is not choked;
• in the event of ducted humidification, the operation of the humidifier
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.
“heaterSteam” +0300075EN - rel. 1.0 - 22.10.2014
To prevent the heating elements in three-phase models hitting each
other or against the internal wall of the cylinder and thus damaging
the appliance, due to vibrations or bumps during transport, the heating
elements are factory-fitted with a centring spring, which has no function
during the operation of the appliance. As the centring spring may hinder
the removal of lime-scale from the elements and diminish the interval
between cleaning cycles, the spring should be removed before the
initial start-up. To do this, remove the cylinder by following the relative
instructions (see Maintenance of the cylinder).

9. ALARMS
9.1 Alarms table
When an alarm is activated a message identifying the alarm is displayed
on the control module. In the event of potentially dangerous alarms, the
control automatically deactivates the humidifier (disablement). For some
alarm events, an alarm relay is activated simultaneously with the signal
(see table).
If the cause of the alarm is no longer valid, the humidifier and alarm
relay output can be reset automatically or manually, according to the
type of problem, while the message displayed is deactivated manually
by pressing the reset-PRG button. If no longer active, the alarm status
continues to be indicated until the reset-PRG button is pressed.
Still active alarms can not be reset.
Unless you are in the programming phase, in the presence of an alarm
condition, the alarm LED starts to flash and the display will show the alarm
code with an alphanumeric code. The message is displayed cyclically, for
a duration of two seconds, alternating with the measurement normally
displayed (if the measurement normally displayed corresponds to
a disconnected probe, the measurement is not displayed; this will
automatically return to the display if the probe is reconnected). In the
event of more than one alarm, the display indicates all the corresponding
codes in sequence, at two second intervals.
Example: room probe alarm E3.

Fig. 9.a
The Ec alarm cannot be reset (high water conductivity).
In the event of the alarm CL (regular maintenance required), the alarm
can be reset only by resetting the hour counter; see Resetting the hour
counter (see chapter 4).
The alarm E1 may appear in two distinct cases:
1. Malfunctioning during parameter memory reading (typically
upon start-up)
The default parameters are reset simultaneously without being
stored in parameters memory (the user can edit the parameters
and reset the correct values). However, we recommend you use the
default parameter access procedure (see chapter 4);
2. Malfunctioning during parameter memory reading (typically
when pressing the PRG key)
Any changes made are cancelled; te parameters can be accessed,
the value can be modified and the memorization operation can be
repeated.

remove it from probe housing and replace it;
PTC temperature sensor
The PTC sensors (one for each heating element) do not require regular
maintenance; they should only be replaced if the safety thermostat is
activated due to operation without water: in fact, the intervention of just
one PTC will cause the control module to shut-down operation.
To replace them, remove the boiler (models UR002-UR013) or the top
panel of the humidifier (models UR020-UR080) as explained in the
previous paragraphs and then:
• remove the covers that protect the heaters;
• disconnect the terminals of the PTC sensor from the terminal block,
remove it from probe housing and replace it;
• insert the new sensor and restore wiring.
Note: the sensor should be inserted until it reaches the limit
switch.

If the fan is faulty:
Models UR002-UR013:
• replace it after having unthreaded the fastening screws;
Solid state relay (SSR)
The solid-state relays (one in the single-phase units, two or three in the
three-phase unit) may damage in two modes: by short-circuit or burn-out.
With regard to power supply, the possible consequences are: continuous
conduction or permanent opening. In the event of malfunctioning,
check the conduction of the relay using a tester.
Models UR020-UR080:
• unscrew the 4 fastening screws placed on the right side of the
structural work and extract the fan from the inside of the panel.
In case of malfunction, the thermal switch can be replaced unscrewing
the fastening screws.
Note:
• for models UR002-UR013 the fan is of suction type;
• for models UR020-UR080 the fan is of exhaust type.

• enable the mechanical device located below the cylinder (A).
For the replacement of the solid-state relay:
• turn the humidifier off;
• open the breaker of the power supply line;
• disconnect the power and auxiliary cables from the solid-state relay
terminal block;
• remove the relay from the electrical panel by using a screwdriver to

Fan
SSR relays are cooled by a fan at the base of the humidifier, for models
UR002-UR013, and placed on top, on the right side of the unit for models
UR020-UR080. With insufficient ventilation the temperature of the
electrical panel may rise excessively until it reaches 65°C. Power to the
solid-state relays is cut off by a special Klixon (heat sensor) with manual
reset (see the wiring diagram), without signalling the intervention. In this
case, check:
• if an SSR thermal breaker has been triggered;
• whether the fan control board is powered (check the input terminals:
24 Vac) and in turn powers the fan (output terminals: 24 Vdc) (only for
models up to 10 Kg/h).

13. ADVANCED FUNCTIONS
13.1 Operating principle
A0=1
HeaterSteam is an isothermal humidifier with steam produced by
heating the heaters completely immersed in a tank filled with water.
This can be tap water or completely demineralised water. The heat
generated by the heaters increases water temperature up to about 100 °
C. The use of demineralized water ensures long service life of the cylinder
and the heaters because virtually no lime deposits can form and grow
gradually. Instead, when using tap water, a part of the minerals dissolved
in water accumulates in the cylinder as solids of various composition. To
prevent this phenomenon, when the water conductivity of the cylinder
exceeds a certain value, a part of the water is drained and reintroduced
periodically to obtain the necessary dilution. For the specific models, the
drain water is mixed with tap water to avoid exceeding the maximum
temperature specified by the applicable local and national regulations
(drain tempering function). The steam generated has a temperature of
about 100 ° C and minimum positive pressure (steam without pressure).
It is virtually demineralized and germ-free.
Steam production is regulated with ON / OFF logic or by continuous
modulation of the nominal power (from 0% to 100%), by means of solid
state relays (SSR); the control logic is of PWM type (pulse length variation)
with programmable time base.

13.2.3 Independent control with relative humidity
transducer (parameter A0 = 2)
13.2 Regulation principles
The appliance is fitted with solid-state relays and steam production can
be controlled continuously as a function of the required quantity, in one
of the following modes.
Steam production is linked to the measurement of % rH, performed by the
relative humidity transducer connected to the regulator, and increases as
the distance from the set point St increases. The maximum production
Pmax (parameter P0), which occurs when the relative humidity is less that
the set point by a value P1, can be programmed between 10% and 100%
of the rated value of the humidifier.
The minimum production Pmin (parameter Pm) can be programmed
between 0% and 10% (default 4%) of the nominal value of the humidifier,
with an activation hysteresis (hy) equal to 10% of P1. The pre-heating
function, if enabled, overlaps the control diagram and is activated when
the relative humidity % rH, measured by the transducer, is higher than
St by a programmable quantity b2. To check that the relative humidity
measured by the transducer is within the pre-set values, the control
module with autonomous control allows two alarm thresholds to be
programmed:
• high relative humidity alarm threshold P2;
• low relative humidity alarm threshold P3.
When these thresholds are exceeded, after a programmable delay
P4, an alarm state is activated, with the closing of the contact of the
corresponding relay on the main control board. With independent
control (parameter A0=2) it is also possible to have an ON/OFF action,
as represented in the graph, by disabling power modulation (setting
parameter b0=0).
13.2.1 ON/OFF regulation (parameter A0=0)
The action is of all or nothing type and it is activated by an external
contact connected to terminals 4I, 5I (see chap. 4), with the setpoint and
the control differential determined by parameters St and P1, respectively.
In case of command from external variable (Analog 52: A52), steam
production is enabled/disabled according to the figure.

Fig. 13.a
13.2.2 Slave control, with signal from an external
regulator (parameter A0 = 1)
P0
Steam production is proportional to the value of an external signal Y,
(selected by programming one of the following standards: 0 to 1Vdc; 0
to 10Vdc; 2 to 10Vdc; 0 to 20mA; 4 to 20mA) the entire range of which
is indicated by BP (proportional band). The maximum output Pmax
(parameter P0), corresponding to the maximum value of the external
signal Y can be programmed between 10% and 100% of the nominal
value of the humidifier. The minimum production Pmin (parameter
Pm) can be set between 0% and 10% (default 4%) of the humidifier’s
rated value. The activation hysteresis hy is based on the value of Pmin
(parameter Pm), however referring to the external signal Y (e.g.: Pmin =
4%, hy = 2%). If enabled, the pre-heating function overlaps the control
diagram, and is activated when the external signal Y is lower than the
activation point for steam production by a quantity b2.

13.2.4 Independent control with relative humidity
transducer and one for delivery humidity
limitation (parameter A0 = 3)
Warning: the parameter A0 and the operating and alarm
parameters: Px and b0 are set in the factory (default values valid
for normal applications). Nonetheless, these can be modified by the user,
following the instructions contained in: “Start-up and user interface”.
Even in this case, the controller modulates the production of steam
according to the measurement of% rH, performed by the main
transducer of relative humidity but, in addition, it limits the value if the
relative humidity% rH2 measured by a second offset transducer placed
in air duct downstream of the humidifier exceeds the maximum desired
value. To prevent the relative humidity measured by the transducer in the
air duct downstream from the humidifier exceeding a value considered
as excessive, the control module with independent control and second
transducer connected allows a high outlet relative humidity alarm
threshold P9, to be programmed. If this threshold is exceeded, after a
programmable delay P4, an alarm state is activated, with closing of the
contact of the corresponding relay on the main control board.
13.4 Automatic total drain due to inactivity
For hygiene reasons it is recommended to empty the boiler to
prevent water residues from remaining inside it in case there isn’t any
humidification request for a long time.
For models UR*H* and UR*T* * the user can set the automatic total drain
in case of inactivity as follows:
• The drain for inactivity is active by default. To disable it, simply go to
parameter “b1” and operate as described in the table in chapter 12;
• Vice versa, if the drain for inactivity has been disabled, to enable it go to
parameter “b1” and operate as described in the table in chapter 12 and
set the maximum inactivity period through the parameter bC.
P0
Steam_Pr_Lim
The automatic total drain for inactivity is enabled by default and the max.
allowable default inactivity period is 3 days: which means that the boiler
is emptied automatically after heaterSteam has been on for at least 3 days
without humidification request.

drain
13.2.5 Application for steam baths (T-type control
module)
The duration of the dilution drain can be adjusted through the new user
parameter bD which defines the new duration as a % of the internally set
default duration: new duration= default duration x bD / 100.
In applications for steam baths, where the control probe measures
temperature rather than humidity, the same considerations are valid as
for the type H control module with modulating action and independent
control.
Recommended CAREL transducer: SSTOOB/P40, ASET030001 or
ASET030000.
Example: if the internally set duration is 10 s and bD= 50%, the new
duration shall be = 10 s x 50 / 100= 5 s.

13.3 Setting the alarm thresholds (type H or
T control module)
The control module panel allows the setting of limit thresholds for the
activation of the alarm in the event where these are exceeded. These
alarm thresholds can be programmed using the following control
parameters:
• P2: high relative humidity alarm threshold, measured by the room
probe;
• P3: low relative humidity alarm threshold, measured by the room
probe;
• P4: alarm signalling delay (to prevent false signals);
• P9: high relative humidity alarm threshold, measured by the outlet
probe (for ducted humidification).
Tab. 13.j
The parameters P2, P3, P4 can be programmed only when A0 = 2 or
3; parameter P9 can be programmed only when A0 = 3. Furthermore,
the control module provides the signaling of excessive conductivity
(and hence the concentration of salts) of the supply water, but only as
a default setting.

0 to 190 % (0 % disables the dilution drains.
Attention: see the comments below
100 %;
10 %.
bD= 0 % means that dilution drains are NOT DONE at all.
WARNING: RISK OF FOAM/CORROSION as the internal
conductivity will increase. We recommend to set bD= 0
after a very careful evaluation of the water quality and
consequences.
bD= 100 % means that the default duration will be used
bD< 100 % means that the duration is < default duration:
less fresh water is introduced after the drain thus reducing its negative impact on the steam production (good
for high precision applications), but the drain valve will
open more frequently in order to control the internal
conductivity (decreasing lifetime).
Attention: RISK OF FOAM IN CASE THE bD VALUE IS TOO
SMALL IN RELATION TO WATER QUALITY
setting the bD for a high-precision control of %UR: bD
should be decreased as much as possible, yet avoiding
foam/corrosion. Find the most suitable value

13.8 PWM fills after dilution and high-level/
foam drains
After a dilution or high-level/foam drain, water is filled into to restore the
water level up to the upper ball cock.
The filled fresh water disturbs the steam production because it decreases
the average temperature of the water inside the boiler: in order to reduce
the negative influence of the fresh water on the steam production, the
user can enable the PWM fills after the dilution and high-level/foam drain.
PWM fills work as follows:
1. the mass of fresh water required to restore the water level is divided
into smaller masses of fresh water;
2. by keeping the partial fills as farther apart as possible from each
other, each partial mass of fresh water is given the maximum possible
time for heating up before the next one arrives, thus reducing the
effect of the fresh water on the steam production.
The number of evaporation cycles between 2 consecutive drains for
dilution is calculated internally, based on the conductivity of the supply
water. The parameter b8 allows the user to set the maximum number
of evaporation cycles allowed between 2 dilution drains. If the number
calculated is greater than b8, it shall be used the value of this parameter
in place of that calculated internally.

13.7 Reduced fills to restore water level after
evaporation
When, during the steam production, the upper floater switches because
the water level has decreased, a fill starts for restoring the water level. The
duration of the fill can be decreased through the new user parameter
bA which defines the new duration as a % of the internally set default
duration: new duration=default duration xbA/100. It should be noted
that, regardless of the value set for bA, the water leve shall always be
restored up to the upper ball cock.

bA= 100 % means that the default duration will be
used
bA< 100 % means that the duration is < default duration: less fresh water is introduced into the cylinder,
reducing the negative impact on steam production
(important in applications of high accuracy) but the
filling valve will be opened more frequently
