Displayed unit = EUWAB12KBZW1.
1 Condenser
The function of the condenser is to change the state of therefrigerant from gaseous to liquid. The heat gained by the gas inthe evaporator is discharged through the condenser to theambient air, and the vapour condenses to liquid.
2 Compressor
The compressor acts as a pump and circulates the refrigerant inthe refrigeration circuit. It compresses the refrigerant vapourcoming from the evaporator at the pressure at which it can easilybe liquefied in the condenser.
3 Refrigerant filter
The filter installed behind the condenser removes small particlesfrom the refrigerant to prevent blockage of the tubes.
4 Expansion valve
The liquid refrigerant coming from the condenser enters theevaporator via an expansion valve. The expansion valve bringsthe liquid refrigerant to a pressure at which it can easily beevaporated in the evaporator.
5 Evaporator
The main function of the evaporator is to take heat from thewater that flows through it. This is done by turning the liquidrefrigerant, coming from the condenser, into gaseousrefrigerant.
6 Pressure port refrigerant circuit
These ports make it possible to measure refrigerant pressure inthe pipes.
7 Charge valve
Allows refrigerant charge in the circuit.
8 Water in/outlet connection
The water inlet and outlet connection allows an easy connectionof the unit to the water circuit of the air handling unit or industrialequipment.

9 Pump (only EUWAP, EUWAB)
The pump circulates the water in the circuit.
10 Pressure regulating valve
The pressure regulating valve is used to regulate the water flow inthe system.
11 Expansion vessel (only EUWAP, EUWAB)
The water in the water circuit expands with rising temperatures.The expansion vessel stabilizes the pressure changes withchanging water temperatures by giving free space to thechanging water volume.
12 Buffer tank (only EUWAB)
The buffer tank reduces the variation in water temperature in thewater circuit. This prevents frequent compressor starts andstops.
13 Drain valve
The drain valve permits complete drainage of the chiller watersystem during maintenance or in case of shut down.
14 Fill valve (only EUWAP, EUWAB)
The water circuit can be filled with water via this fill valve.
15 Air purge valve
Remaining air in the chiller water system will be automaticallyremoved via the air purge valve.
16 Pressure ports water circuit
It is possible to detect any blockage in the water circuit or amalfunction of the pump by means of the 3 pressure ports.
U 7/16 flare pressure ports are provided to connect a device formeasuring the pump pressure and the evaporator pressuredrop. The waterflow can be deducted from these pressures(Refer to "Figures pressure characteristics" on page 10).
17 Water filter
The filter installed in front of the pump removes dirt from thewater to prevent damage to the pump or blockage of theevaporator. The water filter should be cleaned on a regular base.
18 Ball valve
A ball valve is installed in front of and behind the water filter toallow filter cleaning without having to drain the water circuit.
19 Manometer
The manometer allows readout of available water pressure toload.
20 Sensor for inlet water temperature
The measured inlet water temperature is used by the controllerfor regulating the outlet water temprature.
21 Low pressure gauge (optional)
Measurement on low pressure side compressor.
22 High pressure gauge (optional)
Measurement on high pressure side compressor.

WATER CHARGE, FLOW AND QUALITY
For all versions
To assure proper operation of the unit a minimum water volume isrequired in the system and the water flow through the evaporatormust be within the operation range as specified in the table.
Only for EUWAP, EUWAB versions
Connecting pressure gauges to the water circuit (field supply)
It is desirable to know the static height over the pump, for regulatingthe water flow (refer to "Pump start up" on page 10). For this reasonyou need to install pressure gauges or a differential pressure gaugeon the pressure ports.
Maximum allowed installation height in function of the water volume
Make sure to respect following limitations:
If the EUWA is installed at the highest point of the system, then thereis no height difference to be considered.
If the EUWA is placed on a height level other than the highest point,refer to figure 7 to read the maximum allowed height difference infunction of the water volume.
e.g.: If water volume=180 l, the maximum allowed installation heightdifference is 9 m.
Setting the pre-pressure of the expansion vessel
The pre-pressure (Pg) on the expansion vessel has to be set beforefilling the system with water or water/glycol solution in function of themaximum installation height difference (H).
Use dry compressed air or nitrogen for this operation.
The pre-pressure (Pg) to be set is calculated as below:
Pg=(H/10+0.3) bar
H=Maximum installation height of the circuit above the EUWA unit (m)

The chillers are only to be used in a closed water system.Application in an open water circuit can lead to excessivecorrosion of the water piping.
If the water system is drained during some period, rinseout the pump chamber with demineralised water. This toprevent the impeller to be blocked by dried inpurities.
To do this, use the drain tap of the pump. Fill and empty thepump a few times until the removed water is completelyclear. Keep the connections closed to prevent corrosionand dirt entering the water system.
Use of glycol is allowed, but the amount should not exceed40% of the volume. A higher amount of glycol may causedamage to some hydraulic components.

Charging water
For all versions
1 Connect the water supply to the drain and fill valve
2 Open the pressure regulating valve (only for EUWAP andEUWAB) and shut-off valves
3 Use the air purge valves on the unit and purge valves installed inthe highest places in the circuit to remove all air when filling thesystem
Only for EUWAP, EUWAB versions
Water must be filled until the system reaches the required
pressure (Pr). The pressure can be read on the manometer.
The value of the required water pressure (Pr) is depending on thetotal water volume in the system and the pressure in the expansionvessel (see previous chapter).
Refer to figure 7 – Required water pressure in function of watervolume and pre-pressure:
1. Calculate the total water volume in the entire system.
2. Check in figure 7 where the horizontal line of the set prepressure(Pg) cuts the vertical line of the system water volume.
3. At the cutting point, read the required water pressure (Pr) from thelines in the figure.
Example 1
Total system water volume=130 l
Highest point of circuit above the EUWA=5 m
Pg=(5/10+0.3)=0.8 bar
Pr=±2.0 bar
Example 2
Total system water volume=190 l
Highest point of circuit above the EUWA unit=5 m
Pg=(5/10+0.3)=0.8 bar
Pr=±1.7 bar

Switching the unit on
To switch the unit on in cooling mode, proceed as follows:
1 Press the D key for approximately 5 seconds, the G LED willbe displayed.
Then an initialization cycle is started, the L LED, the M LED, the &LED and the é LED will light up depending on the programmedthermostat function.
In case the & LED or the é LED is flashing, it indicates that there is acompressor 1 or 2 startup request. The compressor will start after thetimer has reached zero.
2 When the unit is started up for the first time, or when the unit hasbeen out of operation for a longer period, it is recommended togo through the following checklist.
Abnormal noise and vibrations
Make sure the unit does not produce any abnormal noises orvibrations: check the fixations and piping. If the compressormakes any abnormal noises, this may also be caused by anovercharge of refrigerant.Working pressure
It is important to check the high and low pressure of therefrigerant circuit to ensure the proper operation of the unit andto guarantee that the rated output will be obtained.
3 If the unit does not start after a few minutes, consult the actualoperational information available in the list of direct parameters.Also refer to the chapter "Troubleshooting" on page 18.
Switching the unit off
To switch the unit off and cooling mode is active, proceed as follows:
1 Press the D key for approximately 5 seconds, the G LED willbe extinguished.

Consulting actual operational information
The actual operational information that can be consulted in the list ofdirect parameters consists of:
b01: Evaporator inlet water temperature,
b02: Evaporator outlet water temperature,
b03: Not used,
c10: Total running hours of the compressor 1,
c11: Total running hours of the compressor 2,
c15: Total running hours of the pump.
These are direct parameters, refer to "How to consult and modify thedirect parameters" on page 12.
Resetting alarms
When an alarm is detected, the following happens:
the alarm relay is energized,
the H LED is displayed
the display starts flashing, alternately showing the alarm codeand the inlet water temperature.
The following alarm codes may appear on the screen:
a1: indicates an anti-freeze alarm.
e1: indicates that the NTC probe used to measure theevaporator inlet water temperature is defective.
e2: indicates that the NTC probe used to measure theevaporator outlet water temperature is defective.
e3: indicates that the fuse for the evaporator heatertape (F4)is blown or that there is a reverse phase error or that thereis a problem with the I/O PCB (A2P).
ehs: indicates that the supply voltage is exceedingly high. Inthis case contact a licensed electrician.
el1: indicates that there is a power supply error (example:noise). In this case contact a licensed electrician.
el2: indicates that there is a power supply error (example:noise). In this case contact a licensed electrician.
els: indicates that the supply voltage is exceedingly low. In thiscase contact a licensed electrician.
epb: indicates that the EEPROM on the controller PCB insidethe unit is defective.
epr: indicates that the EEPROM on the controller PCB insidethe unit is defective.
fl: indicates that there was no sufficient water flow eitherduring the period of 15 seconds after the pump wasstarted or for 5 seconds while the compressor is active orthat the overcurrent protection of the pump is activated.
hp1: indicates that a high pressure switch, the dischargethermal protection or the overcurrent protection of thecompressor motor is activated or that the NTC probe usedto measure the ambient temperature is defective.
fl + hp1: indicates that there is most likely an RPP error or that theF4 fuse is blown.
lp1: indicates that the low pressure switch is activated.
ter: indicates that there is a remote user interfacecommunication error.
: communication failure between the digital controller of theunit and the remote user interface. Confirm the correctselection of parameter code h23. This should be defaultsetting 0 and confirm the correction installation accordingto the installation manual of the remote user interfaceEKRUMCA.
To reset an alarm, proceed as follows:
1 Find the cause of shutdown and correct.
Refer to the chapter "Troubleshooting" on page 18.
2 If the alarm codes a1, fl, hp1 or lp1 appear on the display,reset the alarm manually by pressing the E combination keysC and D simultaneously for approximately 5 seconds.
In all other cases the alarm is reset automatically.
Once the alarm is reset, the error code and the H LED no longerappears on the display. The controller continues its normaloperation, displaying the inlet water temperature.
Resetting warnings
During normal operation, the display of the controller may startflashing, alternately showing the inlet water temperature and thefollowing warning code:
hc1: indicates that the compressor 1 requires maintenance:the total running hours of the compressor 1 (directparameter c10) has exceeded the setting of the timerthreshold for maintenance warning (user parameterc14).
hc2: indicates that the compressor 2 requires maintenance:the total running hours of the compressor 2 (directparameter c11) has exceeded the setting of the timerthreshold for maintenance warning (user parameterc14).
To reset the maintenance warning hc1 or hc2, proceed as follows:
1 Consult c10 running hours of compressor 1 or c11 runninghours of compressor 2.These are direct parameters, refer to "How to consult and modifythe direct parameters" on page 12.
2 When c10 or c11 parameter value is displayed, press theC and D key simultaneously for 5 seconds. The value ofthe timer becomes 0 and the warning is reset.
NOTE The parameters b01, b02 and b03 can also beconsulted by the "sensor readout menu". Refer to"How to consult the "sensor readout menu"parameters" on page 12.
To reset the timers of parameters c10, c11 andc15 refer to "Resetting warnings" on page 13.
In case the unit is equipped with freeze protection, it ishighly recommended to install the remote indicatorlamp alarm (H3P) (see wiring diagram supplied withthe unit). By doing so, breakdown of the fuse for theevaporator heatertape (F4) will be detected soonerand freezing of the circuit will be avoided during coldweather.
NOTE If the alarm codes fl and h1 are flashing alternately,the alarm is most probably caused by the reversephase protector or by the fuse for evaporator heater-tape (F4) that was blown.
NOTE Do not forget to carry out the required maintenanceactivities after resetting the timers.
Besides resetting timer c10 and c11, it is alsopossible to reset timer c15 (running hours of pump)in the same way.

Selecting local or remote on/off control
User parameter h07 in combination with the remote on/off switch(installed by the customer) allows the user to switch the unit onwithout using the D or C key on the controller.
When user parameter h07 is set to 0 (=not active), the unit canonly be switched on by means of the D and C key on thecontroller.
When user parameter h07 is set to 1 (=active), the unit can beswitched on or off as follows:
When remote on/off switch is opened, then the unit isswitched off and it is not possible to switch the unit on/offwhile pressing the D or C key on the controller (5 sec).
When remote on/off switch is closed, then the unit isswitched on and it is possible to switch the unit on/off whilepressing the D or C key on the controller (5 sec).
This is a user parameter, refer to "How to consult and modify the userparameters" on page 15.
Selecting dual setpoint control
User parameters p09 (changeable digital selection S7S) and p34
(changeable digital selection S9S) can be used to assign the dualsetpoint control to S7S or S9S.
There are 2 different controls available for 2 different change digitalinputs (S7S and S9S):
p09: changeable digital input selection S7S
0=no function
13=remote dual setpoint
p34: changeable digital input selection S9S
0=no function
13=remote dual setpoint
23=remote on/off
When dual setpoint switch is open, the first setpoint is activated (r01
cooling setpoint).
When dual setpoint switch is closed, the second setpoint is activated(r21 cooling setpoint 2).
This is a user parameter, refer to "How to consult and modify the userparameters" on page 15.
Locking the controller keyboard
Once user parameter h09 is set to 0, the following advancedfeatures can no longer be carried out by means of the controller:
modifying direct and user parameters (parameters can bedisplayed but not modified),
resetting the timers.
switching the unit on/off in cooling or heating
When user parameter h09 is set to 1, the above-describedadvanced features can be carried out using the controller.
To modify user parameter h09 value from 1 to 0, the standard userparameter modification procedure can be used with the standardpassword "22". Refer to "How to consult and modify the userparameters" on page 15.
To modify user parameter h09 value from 0 to 1, the userparameter modification procedure can be used with dedicatedpassword "11". Refer to "How to consult and modify the userparameters" on page 15.
BMS CONNECTION MODBUS
By installing the optional kit address card EKAC10C, you will be ableto communicate with your chiller through a Building ManagementSystem or supervisory system via the Modbus protocol.
General description of Modbus
The address card communicates using the Modbus protocol.
Different parts of the communication network
The communication network consists of two major players:
The Building Management System (BMS) or supervisorysystem.
The chiller or multiple chillers.
The BMS or other supervisory system is able to communicatewith the chillers through the address card.The management of the communication occurs in accordancewith a master-slave structure in polling, where the supervisingBMS is the master and the address cards are the slaves.
The chiller unit can be identified by the supervisor through theassignment of an address within the Modbus network. Theaddress of the chiller unit can be programmed during theconfiguration of the BMS settings.
The variables database of every chiller with installed addresscard is the point of reference for the supplier of the supervisorysystem in Modbus to assign a suitable meaning to the variables.The variables can be read and/or written by the supervisorysystem. Whether the variables are read-only or read/writedepends on the connected chiller and/or the application programbeing used.- If the supervisory system assigns a value to a variable with
read-only status, the command will not be executed at all.- Variables requested by the supervisory system that are not
available in a chiller with an address card are sent from the address card to the supervisory system with zero value. The supervisory system will have to manage these properly.
- In case the supervisory system tries to write a value of a parameter that is out of range, the writing will be ignored.
NOTE This is only in case p34 (changeable digital inputselection S9S) has value 23 (default value).
In case dual setpoint function is selected for thisfunction (p34=13) then the remote on/off controlis not activated.

General information about the Modbus protocol
The Modicon Modbus protocol implemented in the address cardcomplies with the content of the following document:
Modicon Modbus ProtocolReference Guide
June 1996, PI-MBUS-300 Rev. J
The Modbus protocol implemented is of the RTU (Remote TerminalUnit) type based on character tranmission times. The configurationuses the multi-drop feature of RS485. The address sent within theModbus packet addresses the chiller unit.
Implemented RS485 communication settings for the Modbus protocol
The RS485 communication settings are implemented as follows:
Baud-rate: 9600
Stop bit: 2
Parity: none
Implemented commands for the Modbus protocol
The implemented commands in the program are as listed:
Note that:
Due to the variety of chillers with installed address cards, nodistinction is made between input variables (with read-onlystatus) and output variables (with read/write status) so that theknowledge of the database and its management depends on thepart present on the supervisory system.
Due to the general nature of the system, the address cardanswers in the same way to various Modbus commands.
Data representation of the Modbus protocol
DigitalAll digital data is coded by a single bit:
"0" for OFF
"1" for ON.
All digital variables are assigned to bits of consecutive registers,each one having:
the lower-address variable assigned to the less significant bit
the higher-address variable assigned to the most significantbit.
Analogue and integer dataAn analogue and integer value is represented by a 16-bit WORDregister in binary notation. For each register, the first bytecontains the high order bits and the second byte contains thelow order bits.
The analogue variables are represented in tenths:for example, the value 10.0 is transmitted as 0064h=100dfor example, the value –10.0 is transmitted as FF9Ch=–100d
The integer variables are transferred using the effectivevalue:for example, the value 100 is transmitted as 0064h=100d
The address card operates on registers where one register mustbe considered at 16-bit.
In case the BMS or supervisory system tries to write a value of aparameter that is out of range, the writing will be ignored.
Implemented error code
Defining the BMS setting
Activating the Modbus protocol
The Modbus protocol is activated by setting the h23 parameter to 1.
This is a user parameter, refer to "How to consult and modify the userparameters" on page 15.
Defining the unit’s serial address
To define each unit’s unique serial address required forcommunication with the supervisionary system, set parameter h10.
This is a user parameter, refer to "How to consult and modify the userparameters" on page 15.
