HYDRAULIC 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 backﬂ ow prevention valve (supplid - code FWHDCV0003), to avoid the water inside the humidiﬁ er from making contact with the one in the mains;

3. install a mechanical ﬁ lter to retain any solid impurities (connect

before the inlet connection of the humidiﬁ er.

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 an open drain using a funnel to interrupt drain continuity;

6. connect a trap to prevent the return of odors;

7. for models UR020...UR080: connect a drain pipe from the drain pan

at 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 deg

F), so long as the temperature of the feed water is equal to or less than 25 °C (77 deg F) guaranteed.

2.1 Supply water

The supply water for the electric resistance 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:

Attention:treating the water with water softeners or

polyphosphates dispensers is not allowed; it allows for reduced maintenance but favors the concentration of dissolved salts in the water in the cylinder, leading to potential corrosion to the heating elements and possible operation irregularities due to the formation of foam. Should this be impossible to avoid, it requires dilution with ordinary mains water in such a quantity as to guarantee at least 60% of its initial hardness value, and not less than 5°f. Water treatment with reverse osmosis demineralisers is allowed.

Covered

with anti-ad-

hesive ﬁ lm

Tab. 2.a

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.

• for drain tempering versions, water temperature will be 60 °C (140 deg

F), so long as the temperature of the feed water is equal to or less than 25 °C (77 deg F) guaranteed.

Attention: completely demineralised water is aggressive. For

connection to a water system with fully demineralized water use only installation items made of plastic resistant to chemicals (eg. Polypropylene) or stainless steel.

Fig. 3.c

3.5 Condensate drain pipe

During the operation of the humidiﬁ er some 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.). CAREL condensate drain pipes: code 1312353APG.

Caution: the condensate drain pipe trap must be ﬁ lled with water prior to turning on the humidiﬁ er.

D> 200mm

>5°

R> 300mm

H ≤ 2 m

Fig. 3.d

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, use ventilated steam distributors code VRDXL00000 with 230 Vac 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.

A > 0,9 m (>36”) E > 0,9 m (>36”) B > 3 m (>120”) F > 3 m (>120”) C > 1.8 m (>72”) G > 1.2 m (>48”) D > 1.2 m (>48”)

3.4 Steam transport pipe

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

conducting pipes paragraph 12.2);

• 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

4.4 Steam production command signals

Attention: follow this sequence of steps in order to avoid

damaging the control board:

1. program the controller and turn it oﬀ ;

2. make the electrical connections;

3. switch the controller on.

The humidiﬁ er is ﬁ tted with solid-state relays, therefore its capacity can vary from zero to 100% depending on the control requirements. In addition, it can be connected by means of RS485 serial to a remote supervisor. Depending on the type of signal used you can obtain diﬀ erent types of enabling and/or management of the steam production (ON/OFF or modulating). Production enabling is achieved by electrically connecting the terminals 7I and 8I (jumper).

1. Steam production can be launched as follows:

HUMIDISTAT (ON/OFF):

• connect the inputs 4l and 5l (production command) to a humidistat;

• set parameter A0=0 to enable action ON/OFF

1I 2I 3I 4I 5I 6I

EXTERNAL PROPORTIONAL REGULATOR and REMOTE CONTACT (modulating action)

• connect inputs 7l and 8l to a remote contact (enabling);

• connect outputs 5l and 6l (production command) to an external

regulator;

• set parameter A0=1 to enable the modulating action (see chapter 7)

and parameter A2 according to the signal chosen (0...1V, 0...10V, 2...10V,

0...20mA, 4...20mA).

1I 2I 3I 4I 5I 6I

OUT

REF

Fig. 4.o

Attention: prior to connecting the signal you must set the parameters A0-A2-A6. See Paragraph 8.2.

Note: in the industrial sector (CEI EN61000-6-2) signal cables that

come out of the appliance must not exceed 30 m in length: steam production signal cable (terminals 5I, 6I), the remote ON/OFF digital input (terminals 7I, 8I) and shielded cable for RS485 communication.

Fig. 4.l

Attention: prior to connecting the signal you must set the parameters A0-A2-A6. See Paragraph 8.2.

HUMIDISTAT and REMOTE CONTACT (on/oﬀ )

• connect the inputs 4l and 5l (production command) to a humidistat;

• connect the inputs 7l, 8l (enabling) to a remote contact (e.g.: switch,

timer, ...);

• set parameter A0=0 to enable action ON/OFF

2. Enabling and adjusting steam production as follows:

EXTERNAL PROPORTIONAL REGULATOR (modulating action)

• jumper connect inputs 7l, 8l;

• connect outputs 5l, 6l (production command) to an external regulator;

• set parameter A0=1 to enable the modulating action (see chapter 7)

and parameter A2 according to the signal chosen (0...1V, 0...10V, 2...10V,

0...20mA, 4...20mA).

4.5 Control with humidity probes

The main control board, connected to an environment humidity control probe, adjusts the steam production according to the humidity measured. You can connect a second humidity probe on the outlet: in this conﬁ guration, typical of air treatment plants, the main control board continues to adjust the steam production according to humidity, which depends however on the value of the relative humidity measured in the outlet duct.

Note: it is possible to connect active non CAREL probes to the control.

Control with temperature probes

The control of this appliance features autonomous internal control, and is connected to a temperature probe TT (Fig. 4.i). This performs complete control according to the temperature measured inside the environment being controlled. Fig. 4 s shows the connection of the CAREL probe type ASET030001, with measurement range -30T90 °C (Fig.4.s). The CAREL recommended probes have a 0 to 1V output. The control signal must be connected to terminal 5I, whose reference (GND) is represented by terminal 6I. The control can be connected to non-CAREL active probes.

In addition, the maximum and minimum values must be programmed for the signal (parameters A3 and A4 for the room probe; A7 and A8 for the outlet probe). The probes can be powered at the following voltages:

• 12 V stabilised at terminal 4I;

• 32 Vdc from the rectifying of 24 Vac at terminal 3I. The control signals must be connected:

• for the control probe HP (TT in the case of controls for steam baths) to

terminal 5I, whose reference ground (GND) is terminal 6I;

• for the limiting probe HLP, to terminal 1I, whose reference ground

(GND) is terminal 2I.

IMPORTANT WARNINGS:

• To avoid disturbances to control, the ground of the probes or the external regulators must be electrically connected to the ground of the appliance’s control;

• For humidiﬁ er operation terminals 7I and 8I must be connected by an enabling contact or a jumper (default solution). If terminals 7I and 8I are not connected, all internal and external devices commanded by the control are disabled.

4.6 Alarm contact

The humidiﬁ er’s control module features a voltage-free switching contact for the remote signalling of the presence of one or more anomalous events or alarms. Connection to the alarm contact (250 Vac; maximum load: 8 A resistive - 2 A inductive) is made using the removable terminal block H, as per Fig. 4.t. Set up for remote indication of the presence of one or more alarms (terminals 1H, 2H, 3H).

Using diﬀ erent brand probes

Diﬀ erent brand probes can be used, with output signals selected, by programming the parameter A2, (see tab. 4.a) from the following:

• voltage signal: 0 to 1 Vdc; 0 to 10 Vdc; 2 to 10 Vdc;

• current signal: 0 to 20 mA; 4 to 20 mA.

4.7 Final checks

The following conditions represent correct electrical connection:

1. the supply voltage of the appliance corresponds to the voltage on

the speciﬁ cation plate;

2. the fuses installed are suitable for the line and the voltage of the

power supply;

3. humidiﬁ er to be connected to a fused disconnect switch;

4. the humidiﬁ er has been grounded correctly;

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

6. terminals 7I and 8I are connected by jumper or an enabling contact;

7. if the appliance is controlled by an external regulator, the ground of

the signal is electrically connected to the ground of the controller’.

Fig. 5.a

The transmission line can reach a maximum distance of 1000 metres between the two most distant points.

Attention: for the RS485 connections in industrial (CEI61000-6-2)

environment, use shielded cable (with shield connected to PE just on one side, either the terminal or the controller side) with maximum shielded cable length of 30 m. Use shielded twisted pair cable (AWG26), the 485 input stage impedance is 1/8 unit-load (96kOhm). RS485 cables must lay in separate conduits from the power cables.

6. PREPARING FOR OPERATION

Attention: upon installation completion, drain the supply pipe for

around 30 minutes by passing water directly through the pipe and without introducing it into the humidiﬁ er. This will allow the elimination of any scoria and processing residues that may cause the formation of foam during the boiling.

Attention: before starting the humidiﬁ er, check that it is in

perfect condition, that there are no water leaks and that the electrical parts are dry. Do not supply voltage if the humidiﬁ er is damaged or even partially wet!

6.1 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 in tact;

• terminals 7I and 8I are connected by jumper or connected to the

remote ON/OFF contact, and that the latter is closed;

• the probes or the external control device are correctly connected

(and that the ground of these devices is electrically connected to the ground of the main control board);

• the steam outlet pipe is not choked;

• in the event of ducted 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.

6.2 Removing the heating element centring

spring (only for three-phase models)

To prevent the heating elements in three-phase models hitting each other or against the internal wall of the cylinder and thus damaging the appliance, due to vibrations or bumps during transport, the heating elements are factory-ﬁ tted with a centring spring, which has no function during the operation of the appliance. As the centring spring may hinder the removal of lime-scale from the elements and diminish the interval between cleaning cycles, the spring should be removed before the initial start-up. To do this, remove the cylinder by following the relative instructions (see Maintenance of the cylinder).

7. COMMISSIONING

ENG

Once you have completed the steps in “Preparing for operation”, you can start the humidiﬁ er.

7.1 Start

After closing the main switch of the humidiﬁ er’s power supply, turn the appliance on by setting the switch located on the front panel, bottom right , in position I, “ON”. The start sequence is then initiated. This includes the initial phase, the autotest phase, and ﬁ nally, the actual operating phase. Each phase of the starting sequence is characterized by a diﬀ erent display view.

9.1 Alarms table

When an alarm is activated a message identifying the alarm is displayed on the control module. In the event of potentially dangerous alarms, the control automatically deactivates the humidiﬁ er (disablement). For some alarm events, an alarm relay is activated simultaneously with the signal (see table). If the cause of the alarm is no longer valid, the humidiﬁ er and alarm relay output can be reset automatically or manually, according to the type of problem, while the message displayed is deactivated manually by pressing the reset-PRG button. If no longer active, the alarm status continues to be indicated until the reset-PRG button is pressed.

Still active alarms can not be reset.

Unless you are in the programming phase, in the presence of an alarm condition, the alarm LED starts to ﬂ ash and the display will show the alarm code with an alphanumeric code. The message is displayed cyclically, for a duration of two seconds, alternating with the measurement normally displayed (if the measurement normally displayed corresponds to a disconnected probe, the measurement is not displayed; this will automatically return to the display if the probe is reconnected). In the event of more than one alarm, the display indicates all the corresponding codes in sequence, at two second intervals.

The Ec alarm cannot be reset (high water conductivity). In the event of the alarm CL (regular maintenance required), the alarm can be reset only by resetting the hour counter; see Resetting the hour counter (see chapter 4).

The alarm E1 may appear in two distinct cases:

1. Malfunctioning during parameter memory reading (typically

upon start-up)

The default parameters are reset simultaneously without being

stored in parameters memory (the user can edit the parameters and reset the correct values). However, we recommend you use the default parameter access procedure (see chapter 4);

2. Malfunctioning during parameter memory reading (typically

when pressing the PRG key)

Any changes made are cancelled; te parameters can be accessed,

the value can be modiﬁ ed and the memorization operation can be repeated.

10.1 Maintenance

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

Important: before proceeding with any operation:

5 1

ENG

• 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 heaters!

10.2 Maintenance operations

Routine maintenance of humidiﬁ ers using tap water provides:

1. cleaning all the parts that come into contact with water: a. feeding solenoid valve; b. loading/unloading group: c. drain pump; d. heaters; e. collection tray with lime collection basket (models UR002-

UR013);

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.

10.3 Maintenance frequency

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

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.

10.4 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;

• do not use metal devices to clean the heating elements;

• 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;

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

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

Cleaning the heaters

After you have removed the limestone that detached more easily, immerse the heaters for 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; the plates are coated with anti-adhesive ﬁ lm; avoid using any type of metal tools to avoid damaging the antiadhesive ﬁ lm;

Fig. 10.n

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

brush;

18. 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.

Anti-adhesive ﬁ lm (optional)

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.

10.5 Feeding/drain tempering solenoid valve

UR020-UR080

After having disconnected the cables and the pipes, remove the feeding electrovalve (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 present.

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.

For the replacement of the solid-state relay:

• turn the humidiﬁ er oﬀ ;

• open the breaker of the power supply line;

• disconnect the power and auxiliary cables from the solid-state relay

terminal block;

• remove the relay from the electrical panel by using a screwdriver to

lower the fastening lever to the DIN guide;

• hook the guide to the new relay and reconnect the wires.

Fan

SSR relays are cooled by a fan at the base of the humidiﬁ er, for models UR002-UR013, and placed on top, on the right side of the unit for models UR020-UR080. 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;

• whether the fan control board is powered (check the input terminals:

24 Vac) and in turn powers the fan (output terminals: 24 Vdc) (only for models up to 10 Kg/h).

10.8 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).

13. ADVANCED FUNCTIONS

ENG

13.1 Operating principle

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

13.2 Regulation principles

The appliance is ﬁ tted with solid-state relays and steam production can be controlled continuously as a function of the required quantity, in one of the following modes.

13.2.1 ON/OFF regulation (parameter A0=0)

The action is of all or nothing type and it is activated by an external contact connected to terminals 4I, 5I (see chap. 4), with the setpoint and the control diﬀ erential determined by parameters St and P1, respectively. In case of command from external variable (Analog 52: A52), steam production is enabled/disabled according to the ﬁ gure.

13.2.2 Slave control, with signal from an external regulator (parameter A0 = 1)

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

13.2.3 Independent control with relative humidity transducer (parameter A0 = 2)

Steam production is linked to the measurement of % rH, performed by the relative humidity transducer connected to the regulator, and increases as the distance from the set point St increases. The maximum production Pmax (parameter P0), which occurs when the relative humidity is less that the set point by a value P1, can be programmed between 10% and 100% of the rated value of the humidiﬁ er. The minimum production Pmin (parameter Pm) can be programmed between 0% and 10% (default 4%) of the nominal value of the humidiﬁ er, with an activation hysteresis (hy) equal to 10% of P1. The pre-heating function, if enabled, overlaps the control diagram and is activated when the relative humidity % rH, measured by the transducer, is higher than St by a programmable quantity b2. To check that the relative humidity measured by the transducer is within the pre-set values, the control module with autonomous control allows two alarm thresholds to be programmed:

• high relative humidity alarm threshold P2;

• low relative humidity alarm threshold P3.

When these thresholds are exceeded, after a programmable delay P4, an alarm state is activated, with the closing of the contact of the corresponding relay on the main control board. With independent control (parameter A0=2) it is also possible to have an ON/OFF action, as represented in the graph, by disabling power modulation (setting parameter b0=0).

13.2.4 Independent control with relative humidity transducer and one for delivery humidity limitation (parameter A0 = 3)

Even in this case, the controller modulates the production of steam according to the measurement of% rH, performed by the main transducer of relative humidity but, in addition, it limits the value if the relative humidity% rH2 measured by a second oﬀ set transducer placed in air duct downstream of the humidiﬁ er exceeds the maximum desired value. To prevent the relative humidity measured by the transducer in the air duct downstream from the humidiﬁ er exceeding a value considered as excessive, the control module with independent control and second transducer connected allows a high outlet relative humidity alarm threshold P9, to be programmed. If this threshold is exceeded, after a programmable delay P4, an alarm state is activated, with closing of the contact of the corresponding relay on the main control board.

Warning: the parameter A0 and the operating and alarm

parameters: Px and b0 are set in the factory (default values valid for normal applications). Nonetheless, these can be modiﬁ ed by the user, following the instructions contained in: “Start-up and user interface”.

13.4 Automatic total drain due to inactivity

For hygiene reasons it is recommended to empty the boiler to prevent water residues from remaining inside it in case there isn’t any humidiﬁ cation request for a long time. For models UR*H* and UR*T* * the user can set the automatic total drain in case of inactivity as follows:

• The drain for inactivity is active by default. To disable it, simply go to

parameter “b1” and operate as described in the table in chapter 12;

• Vice versa, if the drain for inactivity has been disabled, to enable it go to

parameter “b1” and operate as described in the table in chapter 12 and set the maximum inactivity period through the parameter bC.

The automatic total drain for inactivity is enabled by default and the max. allowable default inactivity period is 3 days: which means that the boiler is emptied automatically after heaterSteam has been on for at least 3 days without humidiﬁ cation request.

Parameter bC

Variation range 1 to 199 days Default 3 giorni Step 1 day Comments the heaterSteam should remain turned on to empty

the boiler UR*H* and UR*T*: the display shows “idr” during the automatic total drain for inactivity.

13.2.5 Application for steam baths (T-type control module)

In applications for steam baths, where the control probe measures temperature rather than humidity, the same considerations are valid as for the type H control module with modulating action and independent control. Recommended CAREL transducer: SSTOOB/P40, ASET030001 or ASET030000.

13.3 Setting the alarm thresholds (type H or

T control module)

The control module panel allows the setting of limit thresholds for the activation of the alarm in the event where these are exceeded. These alarm thresholds can be programmed using the following control parameters:

• P2: high relative humidity alarm threshold, measured by the room

probe;

• P3: low relative humidity alarm threshold, measured by the room

probe;

• P4: alarm signalling delay (to prevent false signals);

• P9: high relative humidity alarm threshold, measured by the outlet

probe (for ducted humidiﬁ cation).

The parameters P2, P3, P4 can be programmed only when A0 = 2 or 3; parameter P9 can be programmed only when A0 = 3. Furthermore, the control module provides the signaling of excessive conductivity (and hence the concentration of salts) of the supply water, but only as a default setting.

13.5 User-adjustable duration of dilution drain

The duration of the dilution drain can be adjusted through the new user parameter bD which deﬁ nes the new duration as a % of the internally set default duration: new duration= default duration x bD / 100.

Example: if the internally set duration is 10 s and bD= 50%, the new duration shall be = 10 s x 50 / 100= 5 s.

Parameter bD

Variation range 0 to 190 % (0 % disables the dilution drains.

Attention: see the comments below

Default 100 %; Step 10 %. Comments bD= 0 % means that dilution drains are NOT DONE at all.

WARNING: RISK OF FOAM/CORROSION as the internal conductivity will increase. We recommend to set bD= 0 after a very careful evaluation of the water quality and consequences. bD= 100 % means that the default duration will be used bD< 100 % means that the duration is < default duration: less fresh water is introduced after the drain thus reducing its negative impact on the steam production (good for high precision applications), but the drain valve will open more frequently in order to control the internal conductivity (decreasing lifetime). Attention: RISK OF FOAM IN CASE THE bD VALUE IS TOO SMALL IN RELATION TO WATER QUALITY setting the bD for a high-precision control of %UR: bD should be decreased as much as possible, yet avoiding foam/corrosion. Find the most suitable value

13.6 User-adjustable max. allowed no. of evaporation cycles between 2 dilution drains

The number of evaporation cycles between 2 consecutive drains for dilution is calculated internally, based on the conductivity of the supply water. The parameter b8 allows the user to set the maximum number of evaporation cycles allowed between 2 dilution drains. If the number calculated is greater than b8, it shall be used the value of this parameter in place of that calculated internally.

Parameter b8:

Variation range 1…50 Default 0.

Note: if b8=0, when the heaters are powered for the

ﬁ rst time b8 shall be automatically set to 2 if conductivity measured in the supply water is <= 100 μS/cm, or at 5.

Step 1

Tab. 13.k

13.7 Reduced ﬁ lls to restore water level after evaporation

When, during the steam production, the upper ﬂ oater switches because the water level has decreased, a ﬁ ll starts for restoring the water level. The duration of the ﬁ ll can be decreased through the new user parameter bA which deﬁ nes the new duration as a % of the internally set default duration: new duration=default duration xbA/100. It should be noted that, regardless of the value set for bA, the water leve shall always be restored up to the upper ball cock.

13.8 PWM ﬁ lls after dilution and high-level/ foam drains

After a dilution or high-level/foam drain, water is ﬁ lled into to restore the water level up to the upper ball cock. The ﬁ lled fresh water disturbs the steam production because it decreases the average temperature of the water inside the boiler: in order to reduce the negative inﬂ uence of the fresh water on the steam production, the user can enable the PWM ﬁ lls after the dilution and high-level/foam drain. PWM ﬁ lls work as follows:

1. the mass of fresh water required to restore the water level is divided

into smaller masses of fresh water;

2. by keeping the partial ﬁ lls as farther apart as possible from each

other, each partial mass of fresh water is given the maximum possible time for heating up before the next one arrives, thus reducing the eﬀ ect of the fresh water on the steam production.

The duration of each ﬁ ll can be deﬁ ned in seconds by the new user parameter bE:

Variation range 1 to 199 days Default 5 seconds Step 1 second

Tab. 13.m

Parameter bA

Variation range 20…100% Default 100% Step 10% Comments bA= 100 % means that the default duration will be

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