WATER CONNECTIONS:
1. install a manual valve upstream (to cut off the water supply);
2. connect the humidifi er to the water supply. For UR002...UR013 models,
use a fl exible pipe 3/4’’G connection. For UR020...UR080 models
connect the fl exible pipe with the non-return valve (supplied - code
FWHDCV0003), to avoid the water inside the humidifi er making
contact with the one in the mains;
3. install a mechanical fi lter to retain any solid impurities (connect
downstream with respect to the tap.
4. 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; for drain tempering versions, water temperature will be 60 °C
(140 °F), with temperature is max 25 °C guaranteed;
5. provide a funnel to ensure continuity interruption in the drain piping;
6. connect a P-trap to prevent the return of odours;
7. for models UR020...UR080: connect a drain pipe from the tank to
the bottom of the humidifi er (this can run into the funnel used for
draining).
8. for drain tempering versions, water temperature will be 60°C (140°F)
with temperature is max 25°C (77°F) guaranteed.

Caution:
• once the installation is complete, fl ush the supply pipe for about
30 minutes by carrying water directly in the drain and without
introducing it into the humidifi er. 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 (fi gure 2.a)
to prevent the return of steam.

2.1 Supply water
The supply water for the electric heater humidifi er 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:
LIMIT VALUES FOR THE HEATER HUMIDIFIER WATER

Tab. 2.a
1. Values depending on the specifi c conductivity; in general: TDS ≈0,93 * σR, 20
°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-;
For particularly aggressive water (conductivity <1 µS/cm), use titanium
heaters (heaterSteam titanium model).
Important: water treatment with polyphosphates or water
softeners is allowed, guaranteeing at least 60% of the initial
hardness value and no less than 5°f.
Softened water reduces maintenance requirements.
Softened water favors the concentration of dissolved salts in the water
inside the boiler, with the consequence of foam formation.
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 (140°F),
with temperature is max 25 °C guaranteed.
Important: 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.
3. STEAM DISTRIBUTION
3.1 CAREL steam nozzles (SDPOEM00**)
Compact steam distributors for small ducts or applications such as steam
baths. They can be mounted either horizontally or vertically (steam
exhaust facing upwords).
Mounting instructions (see gure):

AHUs (DP***DR0)
The steam distributors for AHU or duct applications deliver steam along
their entire length in order to ensure the shortest not-wetting distance.
The distributor should be chosen based on the maximum required
capacity, the dimensions of the AHU/duct and the outlet diameter of
the humidifi er it is connected to. Install far from any obstacle (curves,
ramifi cation, section changes, grilles, fi lters, fans).
Minimum distance between distributor and obstacle: 1…1.5 m (3.3…4.9 ft).
Increase distance in case of:
1. increase in speed of the air in the duct;
2. turbulence decrease.
Mounting instructions (see fi gure):
• drill a series of holes in the wall of the pipe, using the drilling jig of the
distributor (found in the packaging of the distributor);
• insert the distributor with the steam outlet holes facing upwards;
• fasten the fl ange of the distributor using 4 screws.

3.6 Condensate drain pipe
During the operation of the humidifi er part of the steam can condense,
causing effi ciency loss and noise (gurgling).
To drain the condensate connect to the base of the distributor a discharge
pipe with a water trap and a minimum slope of 5° (see fi g.3.d).
CAREL condensate drain pipes: code 1312368AXX (ø 10mm) (CHOSE00516 (5/16”) for North American market) for DP* series linear
steam distributors; code 1312353APG (ø 7mm) - (CHOSE0038 (3/8”) for
North American market) for steam blowers and nozzles.
Caution: the condensate drain pipe trap must be fi lled with water
prior to turning on the humidifi er.

3.7 Outlet pressure limits
The backpressure at the boiler outlet, either positive or negative, depends
both on the relative pressure in the duct/AHU and the pressure drop in
the steam pipe, due to bends or adapters, and the steam distributor.
Carel steam transport pipes have a pressure drop of around 150 Pa/m
(0.021psi) (respecting the maximum fl ow-rate recommended by Carel).
Carel DP* series linear distributors have a pressure drop of around 25 Pa
(0.003psi) (respecting the maximum fl ow-rate recommended by Carel).
Considering these values, the boiler outlet pressure must be:
Note: a pressure of around -200 Pa (-0.029 psi) at the boiler outlet
corresponds to around 20 mm (0.78”) of water inside the boiler (for all
sizes).

4.4 Operating and control principles
Before describing each electrical connection on heaterSteam, below are
some fundamental aspects regarding the control of steam humidifi ers.
4.4.1 Operating principle of aheater humidi er
HeaterSteam is an isothermal steam humidifi er whose technology uses
heaters immersed in a cylinder or boiler fi lled with water. This may be
mains water or demineralised water. The heat generated by the heaters
increases the water temperature up to around 100°C (212°F). The use of
demineralised water ensures long cylinder and heater life, as virtually no
scale builds up. On the other hand, if using mains water, some of the
minerals dissolved in the water accumulate in the cylinder as solids
with diff erent compositions. To prevent this from occurring, when the
water conductivity in the cylinder exceeds a certain value, some of the
water is periodically drained and replenished, thus diluting the water. In
models where featured, the drain water is mixed with mains water so
as to not exceed the maximum temperature allowed by national and
local standards in force (drain tempering function). The steam generated
has a temperature of around 100°C (212°F) and minimal positive
pressure (unpressurised steam). It is virtually free of minerals and germs.
Steam production is controlled with ON/OFF logic or with continuous
modulation from 0% to 100% of rated output, using solid state relays
(SSR); the control logic in this case is PWM (i.e. pulse width modulation)
with a programmable time base.
4.4.2 Control principles
The appliance is fi tted with solid state relays (SSR), meaning steam
production is continuously adjustable based on demand, in one of the
following modes.
4.4.3 ON/OFF control
Operation is all or nothing, and is activated by an external contact; the
maximum percentage of unit production can be set.
4.4.5 Autonomous control with humidity probes
Steam production is related to the % rH reading made by the relative
humidity probe and increases as the value read deviates from the set
point St. Maximum production Pmax corresponds to the case where the
humidity value, read by the probe, is BP away (proportional band) from
the set point. The activation hysteresis hy is settable by the user.
Pmax

BP
Fig. 4.l
Key:
Steam_pr Steam productionYExternal signal
P0Max productionhyActivation hysteresis
PmMin production
To check that the relative humidity measured by the transducer is within
certain preset values, two alarm thresholds can be set in autonomous
control:
• high relative humidity alarm threshold;
• low relative humidity alarm threshold.
When these thresholds are exceeded, an alarm is activated by closing the
corresponding relay contact on the main control board.

4.4.4 Proportional to an external signal (modulating
control)
Steam production is proportional to the value of an external signal Y,
(selectable by programming one of the following standards: 0 to 1 Vdc; 0
to 10 Vdc; 2 to 10 Vdc; 0 to 20 mA; 4 to 20 mA). The maximum production
Pmax corresponds to the maximum value of the external signal Y and
will be the humidifi er’s rated production. The activation hysteresis hy is
settable by the user and refers to the external signal Y.

4.4.6 Autonomous control with relativehumidity
transducer and outlet limit probe
In this case too, the controller modulates steam production based on the
% rH measured by the main relative humidity transducer, while limiting
production if the humidity measured by a second limit transducer,
located in the air duct downstream of the steam distributor, approaches
the maximum desired value. Consequently, to prevent the relative
humidity of the outlet air from exceeding a value that is considered
excessive, the control module with autonomous control and limit
transducer can be set with a high relative humidity alarm threshold.
When this threshold is exceeded, the alarm is activated by closing the
corresponding relay contact on the main control board. The limit probe
allows steam production to be modulated depending on the specifi c set
limit diff erential.
4.4.7 Application for steam baths
In applications for steam baths, in which the control probe measures
temperature rather than humidity, the same rules apply as for
autonomous control with probe.
By setting control to temperature, the humidifi er will continue to produce
steam until reaching the desired set point temperature inside the steam
bath, and consequently the desired saturation of the air (fog eff ect).
Recommended CAREL transducer: ASET030001 or ASET030000, or NTC
probes UEKNTC0*.

4.5 Steam production control signals
The humidifi er features solid state relays (SSR) for modulating steam
production, and consequently capacity may range from 1 to 100% of output,
depending on control requirements. The humidifi er can be connected via
RS485 serial or Ethernet connection to a remote supervisor. Depending on
the type of signal used, steam production can be enabled and/or managed
in diff erent ways (ON/OFF or modulating).
Important: the probe inputs are protected against short-circuits,
and the maximum current delivered (M2.3) is 50 mA. Despite this, it is
recommended to confi gure the “Control type” before connecting the
probes to the terminals.
To help users confi gure the unit, a screen index is shown at the top right of the
display. The screen index corresponds to the sequence in each menu in order
to reach the specifi c page.

4.6 Control with humidity probes
The main control board, connected to a room humidity probe, manages
steam production based on the humidity measured. A second outlet
humidity limit probe can also be connected: with this confi guration,
typical of air handling units, the main control board continues managing
steam production according to the humidity requirement, however
production is limited according to the relative humidity measured in the

• 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);
6. STARTUP AND USER INTERFACE
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.
6.2 Activation sequence
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. English3. Deutsch5. Español7. Chinese
2. Italiano4. Francais6. Russian8. 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);
I

ON
• 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
(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

The possible settings are:
• proportional to external signal: proportional control with signal from
an external controller;
• proportional to external signal with limit probe: proportional control
with signal from an external controller plus limit probe;
• On/O signal: humidity control with humidistat;
• humidity (one probe): humidity control with main probe;
• temperature (one probe): temperature control with main probe;
• humidity with limit: humidity control with main probe and limit probe;
• temperature with limit: temperature control with main probe and
limit probe;
• humidity (two probes): humidity control with two probes, the
controller calculates the weighted average of the two values read;
• temperature (two probes): temperature control with two probes, the
controller calculates the weighted average of the two values read.
For “humidity (one probe)” or “temperature (one probe)” control, one
single main probe can be connected and confi gured, either wired or
wireless.
For “humidity with limit” or “temperature with limit” control, a wired
probe can be connected as the main probe and a wired probe as the
limit. If using wireless probes (maximum of four), two groups of probes
can be defi ned: the group of main probes and the group of limit probes.
In this case, the average will be calculated between the main probes,
depending on the defi ned weight, and the limit probes will also have
their own average, again depending on the defi ned weight.
For “humidity (two probes)“ or “temperature (two probes)” control, only a
group of main probes can be defi ned. Wired probes can be connected to
the main probe input (M2.1) and the limit probe input (M2.5), which will
be used as a second probe, with the average calculated. If using wireless
probes (maximum of four), only a group of main probes can be defi ned,
with the average calculated, depending on the defi ned weight.
For the connections of the signals and/or probes, see chap. 4.
7.2.2 Weighted average of the probes (Installer menu)
If using two temperature probes or two humidity probes, the humidifi er
controller will calculate the weighted average of the probe readings.
In this way, two probes can be used, for example humidity probes, at
opposite ends of the room, calculating the average.
IndexDescriptionParameter
Ea02
Weight of the
probes
Set the weight of the probes
Default: 100
Possible settings: 0-100
Step: 1
The weight of each probe should be expressed with a value from 0 to 100.
The weighted average is calculated as follows:
Weighted average = ((S1×p1)+(S2×p2))
--------------------------- (p1+p2)
where “Sx” is the probe reading, and “px” the relative weight.
To calculate the arithmetic average, equal weights should be set (for
example: p1 = p2 = 100).
If using wireless probes, the weights of each device can also be defi ned;
in this case a maximum of four wireless probes can be connected, and
consequently the formula shown previously for calculating the weighted
average is extended to four devices.

This means the humidity level over time can be considered, bringing the
value to the set point even when the proportional action (P) alone is null.
To activate the Integral function, set humidity control (single probe) on
screen [Ea01]; also adjust the proportional band on screen [Ea05] (for
example, by setting it to a value of 50%). The proportional band has to
be at least 10% or higher, so that screen Ea05a will be visible. On screen

The “Pre-alert” item sets the maintenance pre-alert, which is activated “x”
hours before the maintenance alarm, and where “x” is the value set for the
“Pre-alert” parameter. This allows time to plan the maintenance operation.
The “maintenance alarm” time is the number of cylinder operating hours
before it needs to be cleaned. During the start-up wizard, the feedwater
hardness is entered, and the ”maintenance alarm” depends on this value,
as shown in the table below:
Water hardnessMaintenance alarm
DemineralisedCleaning/maintenance 3000 hours (NO STOP)
0 - -10°fSTOP for cleaning/maintenance 3000 hours
10-20°fSTOP for cleaning/maintenance 1500 hours
20-30°fSTOP for cleaning/maintenance 1000 hours
30-40°fSTOP for cleaning/maintenance 800 hours
If during the wizard the value is set to “automatic”, rather than entering
the hardness value, the maintenance alarm is automatically associated
to the feedwater conductivity read by the conductivity meter. The
following table shows the dependency of the maintenance alarm on
water conductivity:
Water conductivityMaintenance alarm
1 - 50 µS/cmWarning at 3000 hours without STOP for cleaning
maintenance (it is assumed that the water comes from
a reverse osmosis system)
50 - 100 µS/cmSTOP for cleaning/maintenance 3000 hours
> 100 µSSTOP for cleaning/maintenance 1500 hours
The conductivity is read periodically, and the maintenance alarm times is
thus updated as a consequence.
Preheat with autonomous modulating control with probes
The preheating function, if active, overlaps the control diagram and
modulates the power delivered to the heaters in relation to the water
temperature and the preheating set point. The operating principle of the
preheat function is described in the following graph:

Thus, for example, if a water hardness of 15°f is set, the “maintenance
warning” time will correspond to 1500 actual cylinder operating hours;
if the “maintenance pre-alert” time is set to 240 hours (default value), the
maintenance pre-alert will be activated after 1260 hours. The humidifi er
will signal an alarm (and STOP the unit) for maintenance once the
pre-set hours have been reached, plus an additional 120 hours (in the
above example, 1500 + 120 = 1620 hours). It must be stressed that if
demineralised water (manual mode) or 1-50S/cm (automatic mode) are
used, the unit will signal maintenance and cleaning via the warning (3000
hours) only, without ever shutting down the humidifi er.

To ensure production starts quickly, the preheat function can be enabled.
In this way, even when there is no steam request, the water temperature
in the cylinder is kept at a value specifi ed by the user. When production

7.3.2 Fill cycles in PWM mode after drain to dilute
cycles and high level/foam (Installer menu)
After a drain to dilute cycle or high level/foam, the fi ll valve is opened
to replenish water up to the maximum level of the fl oat. The addition of
fresh water aff ects steam production, as it decreases the average water
temperature inside the cylinder: to reduce the negative impact of fresh
water on steam production, the user can activate PWM mode for the fi ll
cycles after drain to dilute cycles and high level/foam.
PWM mode for fi ll cycles works as follows:
1. the mass of fresh water needed to replenish the water level is divided
into smaller amounts of fresh water;
2. by keeping the partial fi ll cycles as far apart as possible, each small
amount of fresh water has more time to heat up before more fresh
water is fi lled, thus reducing the negative impact of the fresh water
on steam production.

Note: when micro-fi lling is enabled, the fi ll valve must be checked and
serviced annually. If necessary, replace the valve.
7.3.3 Total drain due to inactivity (Installer menu)

7.3.5 Thermal shock to assist detachment of scale
(Installer menu)
Considering the natural trend of scale to build up on the inside surfaces of
the cylinder, the materials used are all as smooth as possible. To limit scale
build up even more, especially on the heaters, the thermal shock function
has been implemented. This function completely empties the cylinder
when production stops (and consequently when the water is still boiling).
At the end of the drain cycle, water is refi lled until reaching the top level.
The thermal shock function is set to be activated a certain number of hours
of eff ective production time between two consecutive cycles. On reaching
the time threshold, the thermal shock function will be activated the next
time production stops, without limits in terms of waiting time.
Note: in the event of non-stop operation 24 hours a day, the thermal
shock function will never be activated and will remain constantly pending.

fi ll and drain
times
The duration of the drain to dilute cycle is set using the “variation in drain
time” parameter, which defi nes the time as a% of the default value:
new drain time = (default drain time × variation in drain time)/100
Example: if the default time is 10 s and “variation in drain time” = 50%,
then the new time will be = 10 s x 50/100 = 5 s.
The same also applies to the fi ll time after the evaporation cycle, in this
case using the “variation in fi ll time” parameter:
new fi ll time = (default fi ll time × variation in fi ll time)/100
Remarks on the duration of the drain to dilute cycle: if the drain to dilute
time is very short, there may be the RISK OF FOAM/CORROSION due to
increased internal conductivity.
Low values should be set for the “variation in drain time” parameter only
after having carefully evaluated the water quality and the consequences.

“variation in drain time” = 100 % means that the default value will be used.
“variation in drain time”< 100 % means that the drain time will be less
than the default, consequently introducing less fresh water when next
refi lling, reducing the negative impact on steam production (important
in high-precision applications).
Setting the “variation in drain time” for precise %RH control:
the “variation in drain time” must be set as low as possible, without
however causing formation of foam/corrosion. Proceed by trial and error
so as to fi nd the most suitable value.
Remarks on the duration of the water fi ll cycle: this can be used to off set
water pressure upstream of the humidifi er. Decrease the fi ll time in the
case of high pressure and vice-versa. Nonetheless, feedwater pressure
must be within the range of pressure values specifi ed in Tab 16.b (1-8
bars).
7.4.6 Set feedwater hardness (Installer menu)
The user can set the feedwater hardness. Carel provides an analysis kit
(P/N: KITTH00000) to read feedwater hardness.
The “Water hardness” parameter defi nes the maintenance alarm for
cleaning the cylinder and the heaters.
IndexDescriptionParameter

Water hardness
Set the feedwater hardness
Possible settings:
Hardness: Auto, Manual
Manual setting: 0-10°f, 10-20°f, 20-30°f, 30-40°f
Remarks: if the value is set to Auto, the water
hardness is estimated by the controller based on the
conductivity value.
If water hardness is not set, the controller independently manages
the type of water based on the conductivity reading. Although there
is no reliable relationship between water hardness and conductivity, a
hardness of 40°f is typically equivalent to a conductivity of approximately
900-1000 µS/cm at 20°C.
See paragraph 7.2.7 Cylinder operating hours for information on the
maintenance alarm times in relation to water hardness or conductivity.
7.4.7 No feedwater setting (Installer menu)
In the event of no feedwater, the corresponding “No water” alarm is
displayed. After the alarm has been displayed and the “no feedwater time”
has elapsed, the controller attempts a new fi ll cycle. At each attempt, the
“no feedwater time” is multiplied by the number of times it has already
been carried out. The controller therefore performs a series of attempts to
refi ll with water, for a maximum time of fi ve hours after the alarm occurs.
The alarm is reset only if the water level eff ectively reaches the
intermediate position (yellow LED).

7.4.8 Enable and set high conductivity alarm (Installer
menu)
The controller allows conductivity thresholds to be set for the activation
of alarms when the limits are exceeded. In other words, excessive
conductivity and consequently high concentration of salts in the
feedwater can be signalled. These alarm thresholds are programmable
using the following control parameters:

Defaults:

Possible settings:

Remarks: once the threshold has been exceeded (if the
alarm is enabled), the controller waits for the “alarm delay”
to elapse before displaying the alarm. If during this waiting time the conductivity falls back below the threshold,
the alarm is not activated. This helps avoid false alarms
due to variations in the conductivity reading.
Two high conductivity thresholds can be set. If exceeding the fi rst (lower)
threshold, a warning is shown without stopping operation, while if
exceeding the higher threshold, an alarm is activated and the unit shuts

8. MASTER/SLAVE SYSTEM
8.1 Description of the Master/Slave system
To obtain steam production higher than that provided by one single unit,
several humidifi ers can be connected together in a Master/Slave system.
For example, if steam request is 160 kg/h, a Master/Slave system can be
created with two 80 kg/h heaterSteam units. A maximum of 19 Slave
units can be connected to each Master, meaning a total of 20 humidifi ers
in the same system. The Master and Slave units are connected using a
local Ethernet network, and in the case of just two units (one Master
and Slave) involves a direct connection between the two controllers via
Ethernet RJ45 Category 5 cable.
7.11 Touch display software update
To update the graphic display, simply enter the system menu (from
the home page), Settings menu and enter the password. The following
screen will be displayed:
Fig. 7.f
Plug the USB key into the display (the mini USB port on the display is
accessible from inside the electrical panel or from inside the front panel),

steps described on the display to update the software.
The Ethernet port is available on the humidifi er’s c.pHC controller:
Fig. 8.a
If the Master/Slave system comprises three or more units (maximum 20),
a network switch is required.

Note: use Ethernet CAT-5 STP cable, maximum length 100 m. To
connect the shield, use the earth connector provided on the controller.
8.2 Network switch for Master/Slave
connection
The Master/Slave connection of more than two units requires the use of
an industrial grade switch.
Carel markets a switch (P/N: KITSE08000) that can connect a maximum
of eight units (8 Ethernet ports). If necessary, use several KITSE08000
switches with a cascaded arrangement.

8.3 Type of Master/Slave system installation
The Master/Slave system features one main unit (Master), which manages
operation of the secondary units (Slaves). The external signal or probe
connections, depending on the set control type, are made to just one of
the humidifi ers in the system. The unit that the signal is connected to will
automatically be identifi ed as the Master. Consequently, the Master does
not need to be especially confi gured.
8.4 Master/Slave system con guration
To confi gure the Master/Slave system, proceed as follows:
1. Connect the probes or the external signal to the unit and complete the
confi guration (control type, type of signal, maximum production …);
2. Set the IP addresses of the individual units so that they belong to the same
subnetwork (subnet mask); the screen index for this confi guration is Eh02
(E. Settings – h. Supervision). The IP address is set on the display on each
unit, assigning a diff erent address to each unit in the same subnetwork.
If necessary, contact the local network administrator. Remember that the
default address for each unit is 192.168.0.1, and the default subnet mask
is 255.255.255.0.
3. Connect the units making up the Master/Slave system to the local
Ethernet network via a switch. If using just two units, an RJ45 category 5
cable can be used, connected directly to the Ethernet ports on the two
c.pHC controllers.
4. Confi gure the Master/Slave system by enabling the units one at a time
(this operation can be performed on the display on any of the units):
4.1 Display screen index Ed01 and then access confi guration mode
by pressing “PRG”.
4.2 Enter the IP address for “Unit 1” and confi rm by pressing “ENTER”.
4.3 Repeat the operations described above (4.1 and 4.2) for all the
other units in the Master/Slave system.
(The unit will join the Master/Slave system (online) immediately after
being added to the network.)
Note: the Master unit will always (automatically) be the one with the
lowest IP address out of the units connected to the probes or external signal.
Fig. 8.d
While the Master unit is powered on, the system will be able to operate
even in the event of malfunctions on the Master (alarms, stopped
production,…), as the unit’s controller will send all the required data
to the Slaves. Obviously, unless redundancy has factored into the
total production capacity, steam output in this case will be lower than
requirements.
If the Master is switched off completely, the Master/Slave system will not
be able to read the control/probe signals. Consequently, it is suggested
to connect all the humidifi ers in the system (or at least two units) to the
external signal or fi t them with independent probes).
Note: it may take a few seconds (max 10 s) for the Master to start
sending the production request to the Slave/Slaves. This is also true
when, automatically, the Master unit is changed (for example, in the
event of malfunctions).
The evolved Master/Slave system with Ethernet connection is managed
by the heaterSteam Titanium version by a cascaded connection between
a series of units; for heaterSteam process version, the connection is made
using terminals M8.1 and M8.2 that provide the production request (0
to 10 V). See paragraph 4.10 “Production request analogue output for
connection”.
8.4.1 Maximum Master/Slave system production
In the same way as for the individual unit confi guration, for the Master/
Slave system the maximum capacity can also be set. To set the maximum
capacity, go to menu Ed07 (E. Settings – d. Network), press
the UP/DOWN buttons until reaching menu Ed03.
The “Capacity” parameter identifi es the maximum production request for
the Master/Slave system, and can therefore by set by the user.
The “Maximum capacity” parameter (read-only), on the other hand,
indicates the sum of the sizes of each unit added to the system; this
value is therefore the maximum eff ectively available to the Master/Slave
system. Consequently, “Capacity” will always be ≤ “Maximum capacity”.
In any case, the maximum production can be defi ned for each individual
unit in the system by limiting production from its maximum according
to the size. In this case, “Maximum capacity” will be updated keeping in
consideration these reductions.
and use
Fig. 8.e
Systems set up in this way will be able to cover the steam request. In this
specifi c case, the Master will always be the unit with the lowest IP address
of those connected to the signal/probes. If necessary, an additional
humidifi er (backup) can be installed to cover request in the event of
malfunctions on one of the units in the system.
8.4.2 Unit rotation logic in the Master/Slave system
The activation logic of the units in the Master/Slave system can be set,
choosing between “Grouped” or “Balanced”, on screens Ed03 and Ed04.
On screen Ed07 (E. Settings – d. Network), press
DOWN buttons until reaching menu Ed03 or Ed04 (screen Ed04 is only
shown if rotation is enabled on screen Ed03).
Grouped rotation logic:
and use the UP/
• the units are activated in series, one after the other, according to steam
request.
Example: M/S system comprising two 80 kg/h (176lbs/hr) units, for a
maximum total capacity of 160 kg/h (353lbs/hr). While steam request
remains below 50% (80 kg/h) only one unit will be activated (for
example, Unit 1), as soon as the request exceeds the 50%, the second
unit will also be activated (in the example, Unit 2).
41
“heaterSteam” +0300087EN - rel. 1.3 - 14.02.2020
ENG
Balanced rotation logic:
• the units are activated in parallel at the same time, splitting the total
production request between the number of units in the M/S system.
Example: M/S system comprising two 80 kg/h (176lbs/hr) units, for
a maximum total capacity of 160 kg/h (353lbs/hr). If the request is
50%, the rotation function activates both Unit 1 and Unit 2 at 50% of
production (40 kg/h + 40 kg/h = 80 kg/h). If the request is 90% (144
kg/h) the rotation function activates both Unit 1 and Unit 2 at 90% (72
kg/h + 72 kg/h = 144 kg/h).
If the steam request does not require the use of all the units, the rotation
function can take into account the units with the least operating hours
(auto-rotation function) so as to ensure the individual units total the same
number of operating hours. To enable and confi gure the operating hours
for unit rotation, set the “auto-rotation time” parameter on screen Ed04.
Note: if the “auto-rotation time” parameter is = 0, the auto-rotation
function is disabled.
8.4.3 Advanced preheating function for the Master/
Slave system
Activating advanced preheating on the Master/Slave system allows
the Slave unit or units currently in standby to be automatically preactivated. When the request reaches 90% of production on the units that
are currently operation, preheating is activated on the remaining units.
Activation of advanced preheating also depends on the type of rotation
selected.
Example: M/S system comprising two 80 kg/h (176lbs/hr) units, for a
maximum total capacity of 160 kg/h (353lbs/hr). While steam request
remains below 72 kg/h (90% of 80 kg/h = 72 kg/h) only one unit will
be active (for example, Unit 1). When the request exceeds 72 kg/h,
preheating will be activated on Unit 2 so as to have a faster response
when the request exceeds 80 kg/h. The advanced preheating function
for the M/S system is enabled/disabled on screen Ed04.
Note: the automatic preheating function for the M/S system only
applies to “Grouped” rotation.
8.4.4 Disconnect unit from the Master/Slave system
To remove a unit from the Master/Slave system, thus reducing the number
of units available in the system, use the “Disconnect unit” function on
screen Ed06. This can be done on any of the humidifi ers in the system.
Note: once the unit has been disconnected, this will no longer be
visible in the Master/Slave system, as its IP address will be removed from
the list. If a unit is disconnected erroneously, the system can be restored
on screen Ed01 (entering its IP). This must be done from the display on a
unit that is already connected to the system.
The units in the Master/Slave system can also be selected one by one,
displaying maximum production, unit status, operating hours, current
production request and any alarms.
To enter this display, from screen Ed08, select the desired unit and press
thus accessing screen Ed09. Scroll using the UP/DOWN buttons to
display the details of all the units.
8.4.6 Software backup function in the Master/Slave
system
Master/Slave mode can also be used to manage the software backup
function; if one or more units in the Master/Slave system is aff ected by
malfunction, the system automatically restores steam production by
activating the backup units. The lost production in relation to the steam
request is thus compensated by increasing production on the individual
units (where possible) and/or starting any units in standby.
Even if not strictly necessary, to ensure the backup function, the external
control signal must be sent to all the units in the Master/Slave system; if
using probes on the other hand, each unit must be fi tted with a probe.
Only in this way can complete operation be guaranteed in the event of
malfunctions.
Note: if a unit goes offl ine due to a malfunction or shutdown, it will
temporarily be excluded from the system, and when next restarted it may
take 15 seconds or more to automatically come online again.
8.4.7 Advanced backup functions (software) for
maintenance
During maintenance or cleaning on a unit in the Master/Slave system, the
backup function can be disabled for maintenance. This allows production
to start on a unit in standby, set as backup, before switching off the
humidifi er in question for maintenance. In this way, service continuity can
be guaranteed in applications where required humidity control is very
precise and continuous over time.
To activate backup for maintenance, proceed as follows:
5. Enter the menu with screen index Ed07 (Network)
6. Press the DOWN button to display the list of units (Ed08)
7. Scroll to the unit on which maintenance is required (Unit 1, Unit 2, …)
and press
8. Press to access screen Ed10 and set the “Request switch unit off ” =
YES. Wait for the display to show the message: “The unit can now be
switched off for maintenance” and then switch the unit off .
Once maintenance has been completed, simply switch the humidifi er on
again, and the will automatically come back online.
to confi rm (screen Ed09).
8.4.5 Display Master/Slave system
To display a summary of the Master/Slave system , go to screen Ed08. In
screen Ed07 (E. Settings – d. Network), press the DOWN button to go to
menu Ed08.
Menu Ed08 has fi ve pages in total that display all the units (01, 02, …, 20),
the status of each unit and the current production as a percentage. The
following table explains the Master/Slave network unit status indications:

9. WEB SERVER
ENG
9.1 Integrated web server
The integrated web server is used to confi gure and monitor the main
unit parameters directly from a PC. In fact, using the Ethernet port on
the humidifi er controller, the unit can be accessed via a local network by
simply entering its IP address in the browser.
Fig. 9.a
To log in and access the various menu items, use the installer or service
password (see paragraph 6.12 “Main menu”).
Note: the web server is managed in the heaterSteam titanium
version.
9.2 Connecting to the integrated web server
For the physical connection to the controller from a PC, must use the RJ45
Ethernet port on the c.pHC and an Ethernet category 5 cable.
Important: the controller is not accessible directly on the internet
as a fi rewall guarantees remote access only via a secure connection (Carel
tERA cloud or encrypted VPN connection).
9.3 Description of the web server function
The web server “Home” page provides access to the display, so as to carry
out all the confi guration operations in the same way as if working directly
on the pGD. In addition, there will be an immediate response from unit
concerning its operation in the network.
Fig. 9.d
The main confi gurations and information are:
• UNIT

The PC and the humidifi er controller (or all controllers, for Master/Slave
systems) must be part of the same subnetwork.
The default network confi gurations for the c.pHC are:
unit’s IP address: 192.168.0.1
subnet mask: 255.255.255.0
gateway: 192.168.0.1
For example, the PC’s network settings can be changed as follows:
unit’s IP address: 192.168.0.2
subnet mask: 255.255.255.0
gateway: 192.168.0.1
To do this, access the “Network and sharing center” on the PC and go to
“Local network connection”. Then modify the addresses, as shown above,
for Internet protocol version 4.
Each c.pHC controller can obviously also be added to the Ethernet local
network, allowing the web server to be accessed from any point in the
network and for each humidifi er.

10. HARDWARE BACKUP
For applications that require continuous humidity control, a second
backup unit may be required, which is automatically activated in the
event of a malfunction on the fi rst.
The heaterSteam controller features a dedicated digital input and output
for the backup connection, so as to guarantee, via the normally-open
contact, activation of the second unit.

The hardware backup function must be activated on the menu in screen
Ee01. Screen Ee02 is used to set the unit with higher priority in the event
of simultaneous activation. To ensure service continuity, the external
signal or probes must be connected to both units; in this way, both the
main unit and the backup unit will be completely independent. If using
autonomous control with probes, it is recommended to use dedicated
probes for each unit (main probe and limit probe), in other words, do not
share the probes between the units. This will guarantee service even in
the event of probe malfunctions.
Note: the hardware backup function is managed on the
heaterSteam titanium version.
11.1 Supervisor network protocols and
con guration
The humidifi er can be connected to a supervisor via serial (BMS) or
Ethernet network. The Carel, ModBus and BACnet protocols are supported
as standard by the units.
To confi gure supervision on the BMS port (1), go to “SETTINGS –
SUPERVISION”, specifi cally screens Eh01, Eh02 and Eh03.
If connecting the supervisor to the Ethernet port (2), set the network
parameters (DHCP, IP address, subnet mask, gateway, DNS) on screen
Eh04.
For other supervisor protocols, select the Carel protocol on the BMS serial
port and use the Carel external gateway (supernode for humidifi cation:
SNU0000EM0) combined with the desired supervision card (depending
on the protocol).
Note: Ethernet CAT-5 STP cable, maximum length 100 m. To connect
the shield, use the earth connector provided on the controller.
Note: for BMS and Fieldbus, use shielded cables with the shield
connected to earth.

11.3 heaterSteam tERA service registration
The humidifi er can be connected to the Carel tERA service. This allows
remote monitoring of the humidifi er, saving the variables and therefore
creating a log of humidifi er operation. Use the Ethernet connection and
the humidifi er control port.
To connect the humidifi er to the tERA service, the MAC, the UID code
and password (called “tERA”) of the unit controller are required. This
information is available on the “Resources” page, accessible from the
controller web server (see chapter 9. Web Server).

12. WIRELESS PROBES, INSTALLATION AND CONFIGURATION
12.1 Type of installation and wireless probe
electrical connections
Wireless probes are available for systems where standard wired probes
cannot be used, for example modifi cations to existing installations. An
Access Point (CAREL P/N: WS01AB2M20) is used to connect up to four
wireless probes.
2
3
1
Fig. 12.b
ENG
Recommended Carel wireless probes are the room (WS01G01M00) or
industrial versions (WS01F01M00), both of which measure humidity
and temperature. The type of installation is shown in the fi gure below
(referring to four wireless room probes):
Key:
1. HeaterSteam humidifi er;
2. humidifi er/Access Point connection;
3. Access Point (WS01AB2M20);
4. Wireless probes for measuring
temperature and humidity (WS01G01M00
4
or WS01F01M00).
HeaterSteam/Access point connection:
To connect the humidifi er to the access point, use the Fieldbus
connection on terminal M3 (M3.1: Tx/Rx-, M3.2: Tx/Rx+, M3.3: GND):
Note: the devices have a range of around a hundred metres in a free
space, i.e. without any obstacles. In a closed space, the range varies
considerably depending on the type of environment and the surrounding
objects (shelves, metal partition walls etc.).
If installing multiple wireless probes, the controller will calculate the
weighted average between the various probe readings, depending on
the settings made by the user and the defi ned probe groups. Also see
paragraph 7.4.3 Wireless probes. The controller also displays (locally only)
the battery and signal level for each probe (screen index D05-D08).
The table below shows the part numbers and descriptions of the Carel
devices that can be used:

This assigns the address 2 to the Access Point, with a baud rate (Bit/sec)
of 19200 (N82). The addresses of the four serial probes, on the other hand,
must be set as shown in the table below:
Remember to verify the quality of the wireless signal between the Access
Point and each wireless probe.
For a complete description of the installation procedure, see the Carel
manual on the corresponding probes and Access Point.
To confi gure the probes, go the screens: Ec03, Ec04, Ec05, Ec06 and Ec07,
described in paragraph 7.4.3 “Wireless probes”.
In particular, screen Ec03 is used to enable the wireless probes connected
to the Access Point, knowing that addresses 16, 17, 18 and 19 are Probe 1,
Probe 2, Probe 3 and Probe 4 respectively.
Address: 16
Address: 17
Address: 18
Address: 19
12.2 Wireless probe installation
The main steps for installing the wireless devices are:
• power up the Access Point (12/24 Vac/dc ±10%m, 100mA) and
complete the initialisation procedure, creating the network and
selecting the channel;
• after having opened the domain on the Access Point, complete the
binding procedure so as to uniquely identify each probe.

Demineralised water
The use of demineralised water minimises maintenances times.
Note: we recommend you carry out non/routine maintenance at
least once a year, regardless of the operating hours and the data
shown on the hour counter.
14.4 Maintenance of the cylinder-boiler
This operation is necessary as the lime deposits that form inhibit the
exchange of heat between the heating elements and the water.
Warning:
• do not use detergents or solvents to clean the components in the
boiler and all other plumbing;
• the boiler may be hot! Wait for the boiler to cool down before touching
it or use safety gloves.

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 humidifi er (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.

Models UR002-UR013:
• replace it after having unthreaded the fastening screws;
Fig. 14.x Fig. 14.y
Solid state relay (SSR)
The solid state relays (number depending on the model) can be damaged
in two ways: 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.
14.8 Mechanical discharge of water in the
cylinder
Discharge by gravity without turning on the humidifi er is recommended if:
• the humidifi er is out of order
• it is required to empty the cylinder without turning on the humidifi er.
Procedure:
• make sure the humidifi er is not powered;
• remove the front panel;
• enable the mechanical device located below the cylinder (A).
Models UR002-UR013
Fig. 14.z Fig. 14.aa
Fan
SSR relays are cooled by a fan. This is located at the base of the humidifi er,
for models UR002-UR013; at the top right of the unit for models UR020UR080. With insuffi cient 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.
