2. HYDRAULIC CONNECTIONS

Important: before making the water connections disconnect the humidiﬁ er from the power supply.

Models UR002..UR013 Models UR020...UR080

4 7

Fig. 2.a

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;

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:

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: 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, 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 (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.

D. drilling jig

Note: if using steam hoses with an inside diameter of 30 mm (1.2 in),

remove the 22 mm (0.9 in) inlet section from the steam nozzle.

3.2 CAREL linear distributors for air ducts or 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.

3.3 CAREL blowers for room installation (VSDU0A*, VRDXL*)

Steam distributors for installation in rooms. These come with a fan to assist steam absorption. The VSDU0A* blowers can be used on humidiﬁ ers with ﬂ ow-rates up to 18 kg/h (39.7 lb/h), i.e. models UR002… UR013. They can be connected to the top of the humidiﬁ er, or separately in a remote position using the fastening support VSDBAS0001 (see Fig.

3.c). These distributors have a power supply inside the electrical panel

(24 Vac, Terminals X1, X2).

Fig. 3.c

A > 0,5 m (>19.6”) E > 0,5 m (>19.6”) B > 5 m (>196.8”) F > 5 m (>196.8”) C > 2,1 m (>82.6”) G > 1 m (>39.4”) D > 1 m (>39.4”)

Caution: in order to achieve proper steam distribution observe the distances indicated in the ﬁ g. above.

For the humidiﬁ ers larger than 18 kg/h, the are ventilated steam distributors code VRDXL00000 with 230 Vac power supply, external power supply (maximum capacity 45 kg/h). The distributors are designed for installation in a remote position, and require two steam hoses with a 30 mm diameter, c connected to a “Y” adapter (available as accessories, contact Carel for details on the product code).

C > 1,8 m (>70.8”) E > 0,9 m (>35.4”) D > 1,2 m (>47.2”) F > 3 m (>118.9”)

G > 1,2 m (>47.2”)

In this case, terminal J19.1 on the control board is used as a voltage-free contact (normally open when there is no production - SSR OFF). This

contact has a maximum rating of 2 A.

3.4 Steam transport pipe

• use CAREL ﬂ exible hoses (max 4 m long, see section “Models of steam

conducting pipes”);

• avoid the formation of pockets or traps (cause of condensate

accumulation)

• avoid choking the pipe with sharp bends or twists.

• Use metal clamps to fasten the ends of the pipe to the connections

on the humidiﬁ er and the steam distributor, so that they do not come loose as a result of the temperature.

• avoid strains which include mechanical stress on the cylinder steam

outlet tailpiece

3.5 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.

3.6 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:

boiler outlet pressure > 150 [Pa/m] * steam pipe length [metres] + 25 [Pa] DP + pressure in duct/AHU [Pa]

Boiler outlet pressure values for heaterSteam:

UR002…R013 UR020…UR080 pressure limits at boiler outlet Pa (PSI)

0 to 1500 (0 to

0.218)

0 to 2000 (0 to

0.290)

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).

Important: the humidiﬁ er ON/OFF switch disconnects power only to the electronic controller, and not the other devices, which

therefore remain powered.

Check that the unit’s power supply voltage corresponds to the rated value shown inside the electrical panel. Remove the front panel as explained in chap. 1. To enter the power and probe cables, see the follow the procedures described below:

Models UR002-UR013

1. unscrew the screws and remove the cover (A);

2. if necessary, cut the top part of the conical cable gland (B) and insert

the power cable;

3. connect the electrical wires to the terminal block, reposition the

cover and fasten it using the screws;

To attach the probe cable:

4. remove the knock-out (C) and unscrew the screws;

5. insert the probe cable through the opening created: then fasten the

cable using the screws.

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 a heater 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.

4.4.4 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.

Note: the graph shown above applies when the pre-heating

function is disabled.

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.

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.

4.4.6 Autonomous control with relative humidity 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*.

ENG

“heaterSteam” +0300080EN - rel. 1.0 - 27.04.2016

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.

Note: in industrial environments (IEC EN61000-6-2) the signal cables leaving the unit must not exceed 30 m (98’) in length: steam production signal cable (terminals M2.1, M2.2), digital remote on/oﬀ input (terminals M2.7, M2.8) and shielded cable for RS485 communication.

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 outlet duct.

IMPORTANT WARNINGS: to avoid unbalanced control, the earth of the probes or external controllers must be connected to the unit controller’s earth.

4.11 Final checks

The following conditions represent correct electrical connection:

1. mains power to the humidiﬁ er corresponds to the voltage shown on

the rating plate;

2. the fuses installed are suitable for the line and power voltage;

3. a mains disconnect switch has been installed so as to be able to

disconnect power to the humidiﬁ er;

4. the humidiﬁ er has been correctly earthed;

5. the power cable is fastened to the tear-proof cable clamp;

6. terminals M2.7, M2.8 are jumpered or connected to an enabling

contact;

7. if the humidiﬁ er is controlled by an external controller, the signal

earth is electrically connected to the controller earth.

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.

ENG

“heaterSteam” +0300080EN - rel. 1.0 - 27.04.2016

6. STARTUP AND USER INTERFACE

• 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.

Note:

Selecting and conﬁ guring the model (only for replacement controllers that are not conﬁ gured): if needing to replace the controller

only (heaterSteam process version spare part URH00000P3, heaterSteam titanium version spare part URH00000T3), the ﬁ rst time the controller is powered on, the model will need to be set (capacity and power supply).

6.3 Shutdown

• To avoid stagnation, drain the water from the cylinder by pressing UP

and DOWN together for 5 seconds; to stop the drain cycle, press ESC.

• move the switch to 0, “OFF”.

6.14 Alarms

Any active alarms will be shown on the corresponding screen with direct access from the display.

When an alarm occurs, the corresponding alarm button

starts ﬂ ashing.

In these conditions, pressing the alarm button

once displays the type of alarm. In the event of potentially dangerous alarms, the humidiﬁ er automatically stops steam production. For certain alarm events, as well as the alarm signal, the alarm relay is activated (see Chap. 13 “Alarm table”). When the cause of the alarm is no longer present:

• the humidiﬁ er and the alarm relay are reset automatically or manually;

• the message shown on the display can only be cleared manually (see

Chap. 13 “Alarm table”); Even if no longer active, the alarm status continues to be indicated until “clear display” button is pressed. Alarms that are still active cannot be reset. If there is more than one alarm, the display shows all the alarms in sequence. From the alarm screen, the alarm log can be displayed by pressing “Enter”

. For the complete table of alarms, see chapter 13. Alarm table.

7. USER MENU AND UNIT CONFIGURATION

The following paragraphs describe the heaterSteam programming

menu. Remember that the screen index at the top right on the display

corresponds to the sequence of indices in each menu to reach the

speciﬁ c page (see paragraph 4.4 for further details).

7.1 Main menu

7.1.1 Menu A. Clock (Main menu)

The Clock menu is used to set the time, date and time zone. Setting the

time zone will automatically update standard/daylight saving time.

Screen index Description Parameter

A01

Clock Set the date, time and time zone.

7.1.2 Menu B. Scheduler (Main menu)

The Scheduler menu is used to enable the time bands.

Index Description Parameter

B01

Scheduler Enable time bands

Default: time bands disabled

To conﬁ gure the humidiﬁ er operating time bands for a speciﬁ c day (24h),

use screen B02 (visible only if the scheduler is enabled). A time band can

be set with production disabled (OFF), enabled (ON), or enabled with s

speciﬁ c set point (ON+SET). Setting the ON time band, the unit uses the

main set point conﬁ gured on screen Qb01. If setting ON+SET, the speciﬁ c

set point for the time band can be conﬁ gured.

Once the time bands have been deﬁ ned for one day, press to copy

the currently displayed bands (daily) to the next day. When the time

bands have been set, the display shows the

symbol.

Note: if control is by external signal, the humidiﬁ er can only be

switched ON or OFF.

7.1.3 Alarm thresholds (Main menu)

To check that the relative humidity measured by the probe transducer is within certain predeﬁ ned values, two alarm thresholds can be conﬁ gured:

• high relative humidity alarm threshold, for both the main probe and

limit probe;

• low relative humidity alarm threshold for the main probe.

On exceeding these thresholds, an alarm is activated and the corresponding relay contact on the main control board is closed. Temperature thresholds can also be set.

Index Description Parameter

C01

Alarm thresholds

Set alarm thresholds Low humidity/temperature alarm threshold High humidity/temperature alarm threshold Limit humidity/temperature alarm threshold Defaults: low humidity/temperature: 0% rH / 0°C(32°F); high humidity/temperature: 100% rH / 100 °C(°F); humidity/temperature limit: 100% rH / 100 °C(°F); Possible settings: 0-100

7.1.4 Inputs/outputs (Main menu)

7.2.1 Control type (Installer menu)

To set the type of control, use the following screen:

Index Description Parameter

Ea01

Control type Set the type of control

Default: humidity (one probe) Possible settings: proportional to external signal, proportional to external signal with limit probe, On/Oﬀ signal, humidity (one probe), temperature (one probe), humidity with limit, temperature with limit, humidity (two probes), temperature (two probes)

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/Oﬀ 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.

Index Description Parameter

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.

7.2.3 Proportional control con guration

If using control proportional to external signal or control proportional to external signal with limit probe, the hysteresis, minimum and maximum production need to be set.

Index Description Parameter

Ea03

Control proportional to external signal

Set the hysteresis, min production and max production Defaults: Hysteresis = 2% Minimum production = 4% Maximum production = 100% Possible settings: Hysteresis = 0-100% Minimum production = 0-10% Maximum production = 0-100%

7.2.4 Control from external ON/OFF signal con guration

If using control with On/Oﬀ signal, the maximum production needs to be set.

Index Description Parameter

7.2.5 Modulation con guration (Installer menu)

If using modulating control, the related parameters need to be set:

Index Description Parameter

7.2.6 Limit probe con guration (Installer menu)

A second probe can be connected as a limit probe at the outlet. This probe has the purpose of preventing the relative humidity downstream of the steam distributor from exceeding a set value, conﬁ gured by the user. As this probe has a modulating action, the diﬀ erential can also be set. The limit probe, within its range of activation, has priority over the main probe (as the limit probe set point is higher than the main probe set point).

Index Description Parameter

Ea06

7.2.7 Cylinder operating hours (Service menu)

The “Cylinder op. hours” screen displays the eﬀ ective number of cylinder working hours.

Index Description Parameter

Ea07

Cylinder op. hours

Display cylinder operating hours, reset hour counter and set maintenance pre-alert threshold Default: Pre-alert = 48 hours Possible settings: 0-999

If the cylinder needs to be replaced, the hour counter must be reset using the “Reset” parameter; the hour counter will then start again from zero.

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 hardness Maintenance alarm

0-10°f STOP for cleaning/maintenance 3000 hours 10-20°f STOP for cleaning/maintenance 1500 hours 20-30°f STOP for cleaning/maintenance 1000 hours 30-40°f STOP 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 conductivity Maintenance alarm

1 - 50 μS/cm Warning at 3000 hours without STOP for cleaning

maintenance (it is assumed that the water comes from a

reverse osmosis system) 50 - 100 μS/cm STOP for cleaning/maintenance 3000 hours > 100 μS STOP for cleaning/maintenance 1500 hours

The conductivity is read periodically, and the maintenance alarm times is thus updated as a consequence.

Therefore, for example, if the water hardness is set to 15°f, the “maintenance alarm” time will be 1500 eﬀ ective cylinder operating hours; if the “maintenance pre-alert” time is set to 48 hours (default), the maintenance pre-alert will be signalled after 1452 hours.

Default: Enabled

This procedure checks operation of the level sensor; for further details see chapter 6. “Start-up and user interface”.

7.3.2 Preheat cylinder water (Installer menu)

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 is next needed, the water is thus warmer than ambient temperature and consequently production will start faster.

Index Description Parameter

Eb02

Preheating Enable preheat

Set the water temperature to maintain Set water temperature oﬀ set

Defaults: Preheat disabled Water temp. set point in the cylinder = 80°C (176°F) Oﬀ set = 3%rH (3°C / 5.4 °F)

Set point range: 50-80°C (122-194°F) Oﬀ set range: 2-20%rH (0-20°C / 32-68°F)

The water temperature in the cylinder is read by the passive NTC temperature probe in contact with the cylinder. The operating principle of the preheat function is described in the following graphs, the ﬁ rst for control with probes, the second for control by external signal.

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:

7.3.3 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.

The duration of each ﬁ ll cycle can be deﬁ ned in seconds:

Index Description Parameter

Eb03

Partial ﬁ ll Enable partial ﬁ ll.

Set the partial ﬁ ll cycle time. Defaults: partial ﬁ ll: enabled ﬁ ll time: 5 seconds Possible settings 1-199 seconds

7.3.4 Total drain due to inactivity (Installer menu)

For reasons of hygiene, it is recommended to empty the cylinder so as to prevent water from stagnating inside when there is no humidiﬁ cation request for an extended period. The user can set the automatic total drain due to inactivity time in hours:

Index Description Parameter

Eb04

Drain due to inactivity

Enable drain due to inactivity; set the hours of inactivity without production request that must expire before draining Defaults: drain due to inactivity: enabled; hour threshold: 72 hours Possible settings: 1-999 hours Remarks: heaterSteam must remain on in order to empty the cylinder. The display shows “DRAIN TO DILUTE” during the drain due to inactivity cycle.

Automatic total drain due to inactivity cycle is enabled by default and the maximum inactivity time is three days (72 hours): the cylinder will be automatically emptied when heaterSteam remains on for at least three days without humidiﬁ cation request.

7.3.5 Periodical drain (Installer menu)

If the feedwater is turbid or has a high mineral content, the cylinder can be periodically drained in order to clean and dilute the water as much as possible. For this operation to be eﬀ ective, it is recommended to carry it out at least once every two-three days. The user can set the automatic periodical total drain cycle as follows:

Index Description Parameter

Eb05

Periodical drain

Enable periodical drain; Set the time between one periodical drain cycle and the next (in hours); Defaults: periodical drain: disabled; hour threshold: 10 hours Possible settings: 0-999 hours Remarks: heaterSteam must remain on in order to empty the cylinder. The display shows “PERIODICAL DRAIN” during the periodical drain cycle.

Periodical drain is disabled by default. The periodical drain hour counter considers the eﬀ ective production time.

7.3.6 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.

Index Description Parameter

Eb06

Thermal shock

Enable thermal shock; Set the time between one thermal shock cycle and the next (in hours); Defaults: thermal shock: disabled; interval: 250 hours Possible settings: 0-1000 hours Remarks: the notiﬁ cation center will signal when thermal shock is pending if the time threshold has been exceeded by production is still in progress. During the function, the display will show “Thermal shock” in the unit status graphic area. A notiﬁ cation message will be shown when there are six hours of production left until thermal shock is activated; the pending thermal shock can be cancelled on this screen.

7.3.8 Blower unit con guration (Installer menu)

To best manage the blower units in applications where steam is delivered directly into the room, the blower on and oﬀ times can be set. Delaying activation of the blower unit allows the system to reach the operating temperature before the fan is activated. Delaying deactivation of the blower unit guarantees that parts in contact with the steam will be completely dried, meaning that when next starting, there is no condensate in the steam distribution line, avoiding droplets being blown into the room.

Index Description Parameter

7.4.4 Maximum number of evaporation cycles between drain to dilute cycles settable by the user (Installer menu)

The number of evaporation cycles between two successive drain to dilute cycles is calculated internally, based on feedwater conductivity. To use the automatic calculation, set “Evaporation cycles before drain” = “Auto”.

The “Evaporation cycles before drain” parameter sets the maximum number of evaporation cycles allowed between two drain to dilute cycles.

The number of evaporation cycles used by the controller will be the lower of the value set manually by the user and calculated automatically.

Index Description Parameter

Ec11

Evaporation cycles before drain

Set the number of evaporation cycles between two drain to dilute cycles. Default: number of cycles: Auto; Possible settings: Auto (automatic management according to feedwater conductivity); 1 to 40 Remarks: if the parameter = “Auto”, the number of evaporation cycles between two drain to dilute cycles is set automatically by the controller based on feedwater conductivity.

7.4.5 Duration of the  ll and drain to dilute cycles settable by the user (Installer menu)

On screen Ec12, the duration of the ﬁ ll time after the evaporation cycle and the duration of the drain to dilute cycle can be set in relation to the default parameter values.

Index Description Parameter

Ec12

Variation in ﬁ ll and drain times

Set the ﬁ ll after evaporation and drain to dilute times in relation to the default values Defaults: variation in ﬁ ll time: 100% variation in drain time: 100%: Possible settings: variation in ﬁ ll time: 20-100% variation in drain time: 0-190%

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.

Warning: RISK OF FOAM FORMING WHEN “variation in drain time”

IS TOO LOW FOR THE WATER QUALITY.

“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.

Index Description Parameter

Ec13

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).

Index Description Parameter

Ec14

No feedwater time

Set the time to check for no feedwater. Default: 10 minutes Possible settings: 0 to 20 minutes Step: 1 minute Remarks: if the value is set to 0, no more attempts will be made to reﬁ ll the water and the alarm will not be reset

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:

Index Description Parameter

Ec15

High conductivity

Enable the high conductivity alarm and set the alarm delay. Defaults: enabled: YES alarm delay: 60 seconds Possible settings: enabled: YES/NO; alarm delay: 0-300 seconds 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.

7.4.9 Set high conductivity alarm thresholds (Installer menu)

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 down as a precaution.

Index Description Parameter

Ec16

High conductivity

Set the high conductivity thresholds. Default: pre-alert: 1250 μS/cm alarm: 1500 μS/cm Hysteresis: 25 μS/cm Possible settings: pre-alert: 0-1500 μS/cm alarm: 0-1500 μS/cm Hysteresis: 0-100 μS/cm Remarks: the hysteresis is used to reset the alarm if the conductivity falls below the threshold by the value set for the “Hysteresis”.

8. MASTER/SLAVE SYSTEM

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.

Main technical speciﬁ cations of the KITSE08000 switch:

Number of ports 8 Installation DIN rail Operating temperature -10-60°C (14-140°F) Power supply 12/24/48 VDC

18-30 VAC (47-63Hz) Current @24VDC 0.13A Protection IP30

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.

Master

Slave

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).

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.

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 Master/Slave system conﬁ 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.

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 this heaterSteam 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

and use 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.

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

and use the UP/ DOWN buttons until reaching menu Ed03 or Ed04 (screen Ed04 is only shown if rotation is enabled on screen Ed03). Grouped rotation logic:

• 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).

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.

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:

Symbol Unit status in the Master/Slave system

Indicates the current unit being displayed (PGD or web server)

The unit is: online

The unit is: oﬄ ine

Unit not conﬁ gured and not included in the Master/Slave 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

to conﬁ rm (screen Ed09).

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.

Note: to activate the advanced software backup functions for maintenance, the backup unit must be connected to the probes or external signal.

9. WEB SERVER

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.

Fig. 9.b

The Ethernet port is available on the humidiﬁ er’s c.pHC controller:

M2M9 M8 M1 M5 M6M12

1 1234567821132 31221212

Ethernet

Fig. 9.c

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.

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.

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.

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.

Tab. 12.l

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

Note: the wireless probes are managed on the heaterSteam

titanium version.

12. WIRELESS PROBES, INSTALLATION AND CONFIGURATION

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 or WS01F01M00).

Fig. 12.b

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:

Tab. 12.k

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.

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.

14.1 Maintenance

Maintenance interventions on the humidiﬁ er should be carried out by CAREL Support Service or by speciﬁ cally qualiﬁ ed staﬀ .

Important: before proceeding with any operation:

• cut oﬀ the power supply setting the master switch of the machine to

“OFF”;

• close the shut-oﬀ valve of the water supply line.

• ON/OFF swithc on the device cuts oﬀ power to electronic circuit only,

not to other electrical parts!

14.2 Maintenance operations

Routine maintenance of humidiﬁ ers using tap water provides:

1. cleaning all the parts that come into contact with water: a. ﬁ ll solenoid valve (and the drain tempering solenoid valve for

models where featured);

b. ﬁ ll/drain group: c. drain pump; d. heaters; e. feedwater tank (models UR002-UR013), ﬁ lter and scale collection

bag;

f. level sensor.

2. boiler gasket replacement.

Non-routine maintenance is carried upon every time scheduled maintenance request (code “CL” on display). Therefore, it is necessary to perform complete maintenance of the humidiﬁ er and reset the hour counter.

14.3 Maintenance frequency

Maintenance frequency depends on the amount of water and steam generated.

Tap water

Water hardness 15…25 °f 25…40 °f Daily operating hours 8…10 8…10 No. of maintenance/ year 2 3

Tab. 14.h

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.

ENG

“heaterSteam” +0300080EN - rel. 1.0 - 27.04.2016

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.

To access the boiler:

• shut down the device and open the breaker of the power supply line;

• open and remove the front panel (see chapt. 1).

• completely empty the boiler from water (see the “Shutdown” section);

Models UR002-UR013 (refer to the following ﬁ gures):

Fig. 14.f

a. loosen the fastening strap and remove the steam pipe (1); b. from the boiler cover, remove the pressure compensation pipe (2)

connected to the level control;

c. loosen the fastening strap (3) and tilt the boiler outwards. d. remove the heater protection cover (4), loosen the fastening nuts

and remove the electrical cables. Also unscrew the screw on the earth wire (6);

e. disconnect the probe connector from the partition; f. remove the boiler. Place it on a surface resistant to the water; g. open the cylinder: unscrew the screw and the nut (5); h. lift the cover that the heaters are fastened to, and remove it from the

cylinder;

l. clean the anti-adhesive ﬁ lm that may be present on the inner walls of

the boiler (see paragraph 6.7 “Replacing the parts”);

m. clean and remove the lime from the boiler and reinsert the ﬁ lm

(where needed);

n. after you have completed the maintenance interventions, reinstall

the boiler following the operations described above reversely.

Models UR020-UR080:

a. loosen the screws (Figure 6.i);

Fig. 14.i

b. unthread the top panel and remove it;

l. to replace the heaters refer to the (see paragraph 6.7 “Replacing the

parts”);

m. clean the heaters; n. the heaters (R) can also be cleaned without unmounting the

top cover; this can be achieved by removing the front ﬂ ange and loosening the fastening nuts (Z);

o. now remove the ﬂ ange with the ﬁ lter (C);

Fig. 14.n

p. rinse the inner walls of the boiler and remove the lime using a soft

brush;

q. reinstall the boiler and repeat the previously described operations

reversely; please remind to secure the grounding screws.

For power connections please refer to the wiring diagrams of the heaters next to the heads.

Scale collection bag (optional - only unit 2-13 kg)

On the inner wall of the boiler is present (depending on model) a ﬁ lm made in anti-adhesive material that prevents lime from adhering to the inner walls of the same. For cleaning and replacement:

• remove the boiler cover following the steps given in the previous

section;

• slowly remove the ﬁ lm towards boiler inlet, without forcing it to avoid

damaging the same;

• open the ﬁ lm after having released the click-on couplings;

• clean with water and use a plastic brush, if necessary; replace it if

damaged;

• clean the boiler and remove lime;

• rewind the ﬁ lm on itself by hooking the click-on couplings and reinsert

it into the boiler.

Cleaning the heaters

After you have removed the limestone that detached more easily, immerse the heaters for almeno 30 minutes in a lukewarm solution of 20% acetic acid, using a non-metallic spatula to remove the surface deposits that are still present. Rinse thoroughly; are plates are coated with anti-adhesive ﬁ lm.

14.5 Feed/drain tempering solenoid valve

UR002-UR013

After having disconnected the cables and the pipes, remove the feed solenoid valve (V2) and check the cleanliness condition of the inlet ﬁ lter, cleaning it if necessary using water and a soft brush. Carry out the same operations on “drain tempering” valve ( V1); (if featured, depending on the model).

Heaters

To replace the heaters, unmount them removing the fastening nut (D) on the cover; in this case it is advisable to replace the seal (G).

Fig. 14.r

Note: for sizes 002 - 013, spacers are featured between the heaters to guarantee correct positioning. Release the spacers to remove the heaters. After cleaning, reposition the spacers.

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.

Fig. 14.s

NTC temperature sensor

The NTC temperature sensor is located in probe housing (P) outside the boiler, under the insulation (where featured, depending on the model).



Fig. 14.t Fig. 14.u

• disconnect the terminals of NTC sensor from the terminal block (8),

remove it from probe housing and replace it;

ENG

“heaterSteam” +0300080EN - rel. 1.0 - 27.04.2016

Drain pump Models UR002-UR013

Procedure:

• remove the boiler as shown in par. 6.4;

• identify the drain pump on the base of the humidiﬁ er, unthread the 3

screws (V) and remove it;

• check the condition of gasket (G) and replace it, if required.

Fig. 14.w

Models UR020-UR080

Procedure:

• unthread the 2 screws (V), remove the cover (C) and the drain pump;

• Check the condition of gasket (G) and replace it, if required.

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.



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.

In this case, check:

• if an SSR thermal breaker has been triggered;

• that the controller supplies 24 Vac to the fan. On models U002-UR013

a 24 Vdc rectiﬁ er card is used to power the fan.

)

Fig. 14.ab Fig. 14.ac

If the fan is faulty:

Models UR002-UR013:

• replace it after having unthreaded the fastening screws;

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).
