INSTALLATION INSTALLATION
Installation
Fan installation (front / side)
If the unit is placed in a narrow room or in the ridge of a gable roof, the fan outlet side can be installed at the short side
of the unit. This can be done simply by reversing the dark panels so that the fan panel is moved around to the short side
of the unit. Loosening the corner bracket will eliminate the need for disconnecting cable connections.
Installation
To guarantee proper air suction, leave at least 15cm of space between the wall and the backside of the unit, where the
carbon & dust lters and air inlet are located. At least 15cm of space should also be left between the topside of the unit
and the ceiling. Larger spaces are preferred. The unit must stand free from the wall to avoid contact noises.
The unit should be mounted in such a way that the side of the condensation drain is at least 1 cm lower than the other
side (slope) to ensure that the condensate drains properly. In practice, the 1 cm elevations at all corners – except the
corner of the electrical compartment – are exactly right for a correct fall. Using a spirit level is recommended.
To avoid contact noises, the OptiClimate comes standard with rubber shock absorbers that are suitable for suspended
installation. If the OptiClimate is going to be placed on a solid base, the rubber shock absorbers supplied with the
connection set need to be used.
Special insulating springs can be supplied for areas that have to be extra quiet. Placing the insulating springs on the
supports will ensure that the unit has automatic fall to the condensation drain.
Installation of rubbers Installation of insulating springs
The rubber feet with which the OptiClimate is placed on the pallet are use to suspend the unit by means of thread ends.
A thread end, a large washer and a nut must be tted. (not supplied)

Power Supply
First, the panel at the left side near the manometer should be removed to make the various electrical connections.
A water valve, water leakage sensor, automatic moisture meter, remote control and room temperature sensor are
supplied with the unit. Their cables can be led to the outside through the opening at the bottom of the panel. The power
cable for the power supply can be led through the black feed-through rubber at the side of the unit.
Electrical water valve
The plug of the water valve should be connected using the black cable supplied with the unit, as shown in the illustration
below.
The other end of the cable should then be connected to the appropriate terminals - terminal N and terminal 7 - on the
terminal strip (see page 6). The third connection of the water valve can be used as earthing.
Water leakage sensor
The connection set contains a loose, 5m long white wire: the water leakage sensor. This sensor is connected to the
eighth terminal on the printed circuit-board. (AI08) The sensor cable should be led to the outside through the opening in
the panel and should be placed on the ground at the lowest point. The end of the sensor cable can be split into several
cores using a connector, so that more than one point is secured against leakage.
If the sensor has a black cap, this should be cut off and the cores should be stripped 5 mm. Connect the other side to
the little white plug on the printed circuit-board as shown in the illustration. In case of water leakage, the water supply
will be stopped immediately by means of the electrical valve in the water pipe.

Alarm
Alarm port
The printed circuit-board has an alarm port that is activated (makes contact) when a malfunction (error) occurs. This
contact can be connected to an SMS (GSM) detector or alarm system and it can be set to NO (contact open) or
NC (contact closed) by means of the Settings menu. This means that the contact will be opened or closed in case of
detection. See the manual of the GSM detector or alarm for this.
Automatic moisture meter with light cell
The automatic moisture meter with built-in light cell supplied with the unit is already connected. The cable should be led
through the opening in the panel. The automatic moisture meter should be hung in the room and may NOT be covered.
The light cell in the automatic moisture meter automatically switches the OptiClimate from day to night mode.
Room temperature sensor
The compartment also has a room temperature sensor, which is already connected to the printed circuit-board. (port
AI01) The sensor must be fed through the opening in the panel to the outside. The sensor should be protected against
heat radiation but may not be put in the shade. A protective cover over the sensor is sufcient. There is also a 2nd room
temperature sensor in the compartment. This only needs to be connected onto port AI04 for a dual-room conguration.
(AI04)
The remote control
The remote control contained in the compartment
can be hung in the room but can also be hung
elsewhere. This way the OptiClimate can also be
controlled from outside the room. The four-core
cable is already connected and should be led to
the outside through the opening in the panel. The
order of connection onto the PCB from left to right
is: red*black*green*yellow

Power cables and circuit breakers
Six different OptiClimate models are available. For your safety and the safety of the OptiClimate, the following
specications should be observed when connecting the power supply: use the circuit breakers (MCB) and cable
thickness specied.

The cables for the supply voltage should be led through the feed-through rubber at the side and connected to the left-
hand side of the terminal strip as described in the illustration. The earthing can be connected to the PE terminal or to
the screw on the metal housing at the bottom right of the terminal strip.
High temperature safeguard
Using this safeguard, the OptiClimate can switch off the heat sources (e.g. lamps) when the temperature in a room
becomes too high. The unit has a terminal that can be connected to the timer of a control panel, for example.
The feed wire running to the switch in the timer should be interrupted for this purpose. Terminal 1, for example, is for a
Grasslin clock and terminal 4 for a LeGrand timer.
LeGrand Grasslin
The two ends should be connected to terminals 15 & 16 on the terminal strip in the electrical compartment of the
OptiClimate.
The OptiClimate supplies the power for the timer. If the room temperature exceeds 35°C, the OptiClimate will interrupt
the circuit, switching off the heat sources. ERROR 15 is then displayed on the remote control.
Always refer to the timer manufacturer's manual if a model other than the one shown is used.

WATER-SIDED CONNECTIONS WATER-SIDED CONNECTIONS
Supply and drain connections of the cooling water
The unit has a water inlet and outlet. The inlet should be installed at a draw-off point with a solenoid valve installed
between the draw-off point and the inlet (always check the ow direction arrow on the valve!). The solenoid
valve should be installed as close as possible to the draw-off point, as this is the water seal.
When a leak occurs, the solenoid valve closes automatically. Make sure that the black magnetic coil of the solenoid
valve is directed upwards (preferred) or to the side. If it is directed downwards, condensate from the valve might enter
the coil. Make sure that the solenoid valve is installed at a xed point that is always easily accessible to the user.
Water out
Condensation water outlet
Magnetic watervalve
Water supply16 mm
Isolation
Solenoid valve in the supply pipe of the water
A lter should be placed in the water inlet. This lter prevents blockage in the unit. Disassembly of the lter often releases
dirt into the unit. As such, it may only be removed after contacting the Technical Service department.
It is recommended to insulate the water supply line in order to prevent condensation build-up. The upper water connection
is the water outlet. The water outlet can be connected directly to the drain (sewer). Alternatively, the warm water can
be used for heating purposes.
Note : Only use solid copper or LDPE pipes and afx these properly to the wall using clamps. Always avoid putting the
LDPE under tension. Make sure that the solenoid valve is afxed properly to the wall or another xed point. Never use a garden
hose!
When all the LDPE connections are checked for leaks and the unit operates properly, all are ttings should be glued. You do
this by unscrewing the coupling, applying some glue to the thread and re-tightening the blue are nut. If done properly, the are
ttings will never come loose as a result of vibration. If it is necessary to loosen the are ttings, then two water pump pliers will do
the trick.
Copper pipes of 15 mm or LDPE pipes of 16 mm are sufcient for all units. If several units have to cool at more than
15 kW, the main pipe should be 20 mm copper or 20 or 25 mm LDPE. If the supply pipe has high pressure, a copper
pipe of 15 mm will cool up to 30 kW.
All types of cooling water (tap, well, pond or swimming pool water) can be used for cooling. However, tap water is
preferred because you won't need to rely on additional electric pumps. Well water contains clay and iron particles that
accumulate on the inner wall of the heat exchanger. The result is that sooner or later the unit will cool less effectively or
not at all. If you use well water, you can install a lter, but such a solution requires maintenance. A normal 22mm tap
water connection has sufcient capacity to continuously cool three or four 15000pro2 units at 45-60 kW.
We also have suitable solutions for larger installations when there are problems with the water supply and discharge.
In such cases, please contact the Technical Service department.
Discharge of the condensation water
The unit will also dehumidify the air during cooling. The moisture extracted from the air comes into the condensation
drain. The condensation drain is connected to a sturdy garden hose or a pipeline that does not bend easily. The
condensation water drips from the hose, which can be connected to the drain pipe. The condensate can also be used
as feed water. The cooling block has been adjusted to prevent metals or oxides from entering the condensate. This is
ideal when the only feed water available is hard water.
The drain pipe of the condensation water may not have loops and may not be put under the water level in a drum.
If the unit is installed at the same level or lower than the drain or sewer, a condensation lift pump can collect the water.
This small lift pump pumps the water through a hose of 9mm to a height of 4 metres into the drain. Stronger pumps are
also available.
Drain pump of the condensation water incorrect drain installation
The drain to the pump must not be under the water level and the pipe may not have loops as shown above.
It's possible that too much air is sucked in through the condensation water pipe causing the condensate water not to drain
properly. Then there is too much resistance in the intake system. Dimension hoses of e.g. a plenum box as large as possible
and ensure that during operation all panels are mounted on the unit. A special syphon can also be mounted. Ask your dealer.

8) Using the automatic moisture meter for dehumidifying during the night
The automatic moisture meter can be set to the required maximum air humidity during the night. If the Night mode is
active and the automatic moisture meter indicates that the unit should dehumidify, the Drop icon starts to ash. During
dehumidication the electric heating elements will be activated for the pro3. This does not happen for the pro4. During
dehumidication the pro3 will consume water and the pro4 will not.
Dehumidication during the day (only pro4)
Both the pro3 and the pro4 will always dehumidify as long as there's a demand for cooling. However, the pro4 can
also dehumidify when no cooling is required. This function can be activated by setting option D:32 to 1 in the menu.
During daytime dehumidication no water will be consumed.
If, for example, a constant air humidity and temperature are required in a climatic chamber, cool at night must be
activated in the menu. By pressing and holding the M key the light cell is deactivated and by pressing and releasing the

11) Water Leakage safeguard
If there is water on the ground - due for example to an incorrectly mounted coupling or a blocked sewer - and the
water makes contact with the water leakage sensor (the at white wire with two blank cores at the end), the unit will
stop cooling and the solenoid valve will close immediately. The unit will only start operating normally after the leak is
repaired and the fault is reset by pressing the On/Off key.
12) Alarm port
The printed circuit-board has an alarm port, which makes contact when an alarm or error occurs. This contact can be
connected to an alarm system or SMS (GSM) detector.
13) Compressor Active mode
If the compressor operates, the display will show the Compressor icon at the bottom right-hand side. It will
disappear when the compressor is turned off. The compressor only operates during the DAY period, if the
set temperature is exceeded, and during the NIGHT period, if the set air humidity is exceeded.
14) Heating Elements Active mode
If the heating elements are turned on, the display will show the Hot Air icon at the bottom right-hand side.
It will disappear when the heating elements are turned off. The heating elements only operate during the
NIGHT period, if the temperature reaches a value below the set value.
Setting the cooling capacity
Capacity control
The capacity is factory set at 1.6 MPa
1.5-1.7MPa is an average setting. Your specic application might require higher or lower cooling capacity. The
maximum cooling capacity is at 1.3MPa and the minimum cooling capacity is at 2.0MPa. The unit will consume more
water at a higher cooling capacity than at a lower cooling capacity.
To adjust the cooling capacity, turn the set screw of the capacity control. This set screw is located at the side of the unit
under the Cooling Capacity Control sticker. By turning the set screw to the left, the pressure will increase and the cooling
capacity will decrease, and by turning the set screw to the right, the pressure will decrease and the cooling capacity
will rise. It is recommended to do this if there are heat sources in the room, so that the unit will not turn off constantly
because the temperature in the room drops below 16°C.
(The pressure on the manometer is not the water pressure, but the pressure of the refrigerant).
This menu allows you to change certain settings and to set the heating, temperature safeguard, auto restart and
hysteresis. Pressing the Skey for more than 6 seconds will open the Settings menu. The display will show a capital D:
followed by a number from 01 to 29. Briey pressing the Skey repeatedly, allows you to scroll through the settings.

To restore the factory settings, press and hold the M key in the Settings menu. All settings will now be restored to
factory settings. Conrm this with the on/off key.
D:01 Switching the heating elements on/off
The OptiClimate has three heating elements. The heating elements of 1-phase systems are connected to 1 phase and
the heating elements of 3-phase systems are divided over 3 phases.
Each of these elements can be switched on and off individually in the Settings menu. If a central heating system is
used for heating, for example, all of these heating elements can also be switched off at the same time.
Setting:
D:1 =3 means all three elements will heat.
D:1 =2 means two elements will heat.
D:1 =1 means one element will heat.
D:1 =0 means all elements are off.
D:02 Temperature safeguard
If the room temperature exceeds 35°C, terminals 15 and 16 on the terminal strip of the unit will switch the heating
elements off. The switch-off temperature can be changed using the D:02 setting. The minimum temperature for switching
off is 30°C and the maximum temperature is 40°C. If the temperature drops below the set temperature for cooling mode
again, the safeguard will switch off.
The safeguard does not impact the operation of the OptiClimate, however, the display will show the error message
E:15 (see also the fault code list).
D:03 Auto Restart after power interruption
If the power is interrupted when the unit is on and the power is restored, the unit will switch on by default. If you want
the unit to remain off after a power interruption caused by an external fault, you should change the D:03 setting.
Setting:
D:03 = 0 means Auto Restart is off.
D:03 = 1 means Auto Restart is on. This is the default setting. The display will show error code 14 in case of power
interruption. See also the fault code list.
D:04 Night cooling (Cool at Night) on/off.
Using this setting, the night cooling can be switched on.
D:04 = 0 means Cool at Night is off. This is the default setting.
D:04 = 1 means Cool at Night is on.
If, in the timer off mode the minimum temperature for example is set to 22°C, the unit will cool the room to 22°C in the
night mode. If the room temperature drops below 22°C, the unit will begin to heat the roo This function is useful in warm
climates, in a very well-insulated room or with other sources of heat that cannot be switched off.
When the Cool at Night function is active a moon icon will be shown on the display.
D:05 Pre-Heating on/off.
Pre-heating can be switched on using this setting.

Using this setting, you can switch on/off the cooling of two rooms alternately.
D:07 = 0 means Dual Room operation is off. This is the default setting.
D:07 = 1 means Dual Room operation is on. If the Dual Room function is active,
the display will show the house icon at the bottom right-hand side.
To use this function, you will have to order a three-way valve and a connection set consisting of a three-way valve,
plenum box, second temperature sensor, external water seal and an extensive installation/user manual.
D:08 Alarm port N.O. (Normally Open) or N.C. (Normally Closed)
Using this setting, the alarm port can be adjusted.
D:08 = 0 means N.C. Normally closed. This is the default setting.
D:08 = 1 means N.O. Normally open.
Refer to the user manual for the correct settings of the SMS (GSM) detector or the alarm system that should be connected.
D:09 Water Valve options
You can opt to open the water valve only if there is a demand for water or only use the water valve if the water leakage
sensor detects a leak. Setting D:09 to 0 will only open the valve during cooling. Setting D:09 to 1 will only open the
valve when a leak occurs.
D:10 Timer port
If D:10 = 0, ports 15 and 16 will interrupt the High Temperature alarm. If D:10 = 1, the high temp alarm will not
occur through these contacts. If D:10 = 1, port 16 is common and ports 16 & 17 will be each other's alternate
contacts. The clock of the OptiClimate (OC) will operate these make-and-break contacts and the clock/timer of the OC
can replace the clock on the control panel. The lamps will operate synchronous with the cooling mode of the OC. To
install a High Temperature safeguard, contact 16 should be aligned with the alarm port on the printed circuit-board.
If there is a High Temperature alarm, this alarm will interrupt the timer’s signal and the temperature safeguard will still
operate. The setting of the alarm port should then be the standard setting (0 = N.C.).
D:11 Hysteresis of the temperature
Using this setting, you can adjust the hysteresis (bandwidth) of the temperature control. This is the temperature difference
required to switch the compressor on and off.
Setting:
D:11 = 2 means the hysteresis is 2. This is the default setting.
The hysteresis can be set from 1°C to 4°C in steps of 0.5°C. If, for example, the day temperature is set to 28°C and
the hysteresis to 2°C, the unit w cool at 29°C and stop idle time of the compressor should also be decreased. (D:27)

D:21 Cooling block too hot
Using this setting, you can determine at which temperature the Cooling block too hot alarm is activated. The settings
in D:21 are 24°C (standard), 30°C(maximum), 15°C (minimum). To activate the alarm, the temperature has to be too
high for a certain period of time. The time is determined by D:22. D:21 and D:22 jointly determine when Error 11
is activated.

D:26 Temperature compensation of the Dual Room temperature sensor
Using this setting, you can calibrate the second room temperature sensor in the Dual Room conguration. The settings
in D:26 are 0°C (standard), 5°C (maximum), -5°C (minimum) set in 0.5°C increments.
D:27 Idle time of the compressor
Using this setting, you can adjust the idle time between Compressor Off and Compressor On. Setting: D:27=15
means the idle time is 15 seconds. This is the default setting. This setting may be used if the temperature values in the
room change too much because of the time that the compressor is in idle mode.
D:28 Water Leakage Alarm on/off
Using this setting, the water leakage alarm can be switched on or off.
If D:28 is set to 1, the alarm is on.
If D:28 is set to 0, the alarm is off.
D:29 Display lighting
Using this option, you can switch the lighting in the display of the remote control on and off.
0 = Automatic (default)
1 = Always on
D:30 Beep on/off
The tone that is generated when the remote control is used can be turned on and off.
0 = off
1 = on
D:31 Fahrenheit/Celsius
The temperature shown on the display can be displayed in Fahrenheit and Celsius
0 = Celsius
1 = Fahrenheit
D:32 Super dehumidication (only PRO4)
This function allows for dehumidication in the day mode without a demand for cooling.
0= super dehumidication off.
1= super dehumidication on.
Inspection/Maintenance
Frequently check whether all couplings of the water connections are properly tightened. Also check that there are no
leaks. Frequently check whether there is no thickening of the black coil (black block on the brass valve) of the brass
solenoid valve (water seal). In case of poor contact (moist contact), the coil can become too hot and expand. If this is
not xed, the coil can burn out and the solenoid valve will no longer open.
The dust lter at the backside of the unit should be checked every 10-12 weeks for dust accumulation. If the lter has a
layer of dust, the dust should be removed using a vacuum cleaner.
The carbon lter should be replaced every 10-12 weeks in order to guarantee proper operation of the unit. This is
essential and should not be forgotten! If this is not carried out, the lter will break down sooner than normal. To replace
the carbon lter, you rst have to remove the dust lter.
Note: If you want to work with a humidier, make sure that it is connected to a reverse osmosis lter or scale lter.
Fan faults caused by lime deposits are not covered under the warranty.
If the dust lter is still clogged with white particles when using a humidier in conjunction with a scale lter, then an
osmosis lter is required. The water is too hard to use with a scale lter. There is no need to use a humidier if the space
is not too large.
Fault analysis and error messages
If the unit does not switch on (and the remote control display and the LEDs on the printed circuit-board are off), most
likely there is no power supply. It is also possible that the internal fuse has blown. This fuse is located near the printed
circuit-board in a synthetic housing.
If there is power supply (the LED on the printed circuit-board ashes and the remote control display shows E:01), but
the unit does not switch on, two of the three phases - it does not matter which - should probably be switched. If the
circuit breaker trips when the unit starts to cool, most likely an incorrect value or incorrect type was installed. Check the
technical specications (page 8) for the correct details.
If the unit makes strange noises or is cooling poorly, check the manometer to ensure that the pointer is not pointing too
far to the right from the centre of the screen and check that the water temperature does not exceed 50°C . If that is the
case, make sure that the unit receives more water and check whether the pointer of the manometer drops. Subsequently,
set the manometer as described in the Settings section on page 14.
If water continues to ow through the unit while the unit is off, it might be possible that the solenoid valve is mounted
incorrectly. Check the arrow on the brass housing. If water drips from the sides of the unit, you have a problem with the
condensation water drainage. Check whether the unit has sufcient fall (see the Installation section) using a spirit
level. It is also possible that the condensation hose has too many loops/bends or is blocked.
Fault code list
Error 01 = Usually means that the phases are crossed (reversal). Only active in the 15000 series.
Two of the three phases - it does not matter which - should probably be switched. If the unit has operated before,
the phases are connected properly. You may have a problem with the power supply (voltage). You can check this by
observing which LED is burning on the little white cupboard in the top of the electrical compartment.
Over voltage = Voltage is too high
Low voltage = Voltage is too low
Phase loss = Phase is interrupted
Reversal = Phase sequence is incorrect (crossed)
Normal = Phases are connected properly and the voltage is correct
Error 02= Condensate does not drain.
Check the condensation drain for blockage and make sure the unit has sufcient fall towards the condensation drain.
Error 03 = Discharge water temperature is higher than 57°C
If the error message appears when the unit is already operating for a while, then too little or no water ows through the
unit. The pressure may be set too high. The maximum permitted pressure is 2.2MPa.
See the setting the cooling capacity section (page 14) for the correct ow.
Error 04= Ambient temperature is too low
The unit is placed in a cold environment, causing the risk of freezing.
The room in which the OptiClimate is installed should be warmer than 4°C.
Error 05= Ambient temperature sensor is not connected or is defective
Error 06= Cooling block temperature sensor is not connected or is defective
Error 07= Return cooling temperature sensor is not connected or is defective
