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 condensate drains – 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 also 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 cord
First, the panel at the left side near the manometer should be removed to make the various electrical
connections. A magnetic 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.
Electric solenoid valve
The plug of the solenoid 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 solenoid 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. 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 back and stripped 5mm and the cores should be stripped. 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 port
The printed circuit-board has an alarm port, which is activated (makes contact) by a malfunction (error). This contact
can be connected to a GSM detector. The contact can be set to NO (contact open) or NC (contact closed) using 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. This
sensor should be led to the outside through the opening in the panel and should be hung at the level of the upper side
of the vegetation. 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.
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.

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.
16

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.
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.

L N
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 drainage
Condensate drainage
Solenoid valve
16mm PE pipe
Pipe insulation
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.

WATER-SIDED CONNECTIONS PUTTING INTO OPERATION
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 These are 3 or 4 OptiClimate 15000 units.
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.

Inverter
The OptiClimate inverter models adjust the cooling capacity to the need. Non-Inverter models operate on
an on / off basis, while the inverter models run the compressor harder/ softer when more or respectively
less cooling capacity is required. This provides an even more stable climate and prevents the frequent tripping
of the unit in case of over capacity.
The inverter function operates on the basis of the fan speed. This means that the fan can be set to automatic
in the day position, using the remote control (FN). If the fans are set at a xed rate, the inverter
function is switched off and the compressor also runs at a xed rate. (resp. low / middle / high). For the night position,
we recommend that you always use the low setting.
4) Temperature setting
Users can set the temperature from 16°C to 34°C.Pressing the

or

key will show the set temperature SET TEMP on the
display. By pressing it once more, you can set the required temperature. The set temperature will be saved and stored
after 3 seconds. Switching between day and night temperatures is done using the Mmode key.

6) Automatic Light Cell setting (Day /Night programme)
The automatic moisture meter in the pro3 series has a light cell, which switches to the day mode when it sees the light
is on and to the night mode when the light is off. Only the Day/Night temperatures have to be set, the rest is done
automatically.
If you want to set the unit manually, the automatic light cell can be switched off and the unit will operate manually.
By pressing the M key for 3 seconds, the mode switches from light cell to manual. By pressing the Mkey again for
3 seconds, the mode switches from manual to light cell. If the automatic light cell
is activated, the display shows an A.
Note: It is important to note that when the Timer setting is programmed the automatic light cell mode is
deactivated. Therefore, program a Timer only if you want to use advanced options. The Timer mode is active
when a clock iconappears in the display.
The external automatic moisture meter for the light cell should be connected to the terminal strip in the electrical
compartment (terminals 12, 14 and 18). Otherwise the unit will remain in the night mode because light is not detected.
This is connected by default.
7) Timer Setting (DAY/NIGHT programme)
As a general rule, we recommend using the automatic light cell mode. Only set the timer if you do
not want to work with the light cell!
This function can be used to set the DAY/NIGHT programme. The programme restarts every day regardless of which
day it is. If the timer is set, the display will show the clock icon next to the time: 
Press the Tkey for 2 seconds. When "---", ON becomes visible, you can change the timer setting. Pressing the

or

key will allow you to set the hours of the ON time. Pressing the Tkey again will allow you to set the minutes of the ON
time. The ON time is the time that the unit will start to cool.
Pressing the Tkey again will allow you to set the OFF time. The OFF time is the time that the unit will start to heat/
dehumidify. If the timer is not set yet, the display will show "--:--" or the time that was already set.
Example:
The unit must cool between 8:00 AM and 8:00 PM.
The ON time should then be set to 8:00 AM
and the OFF time to 8:00 PM
AM = after midnight (from 0:00 to 12:00 hours)
PM = after noon (from 12:00 to 24:00 hours)

Deleting the time when setting the timer (switching off the timer)
Press the Rkey, and the time is deleted. The display will show "--:--". CLOSING: Press the Tkey three times to close
immediately or wait 10 seconds to close automatically.
The settings of the current time and the timer settings
should run synchronously with the times of the control panel.
All clocks must run synchronously when the timer function
is used.
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 electrical heating elements will switch on and water will be consumed in the pro3. This will not
happen with the pro4.
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.
If continuous drying without uctuations is desired, or an as low as possible relative humidity, the Pro4 can also
dehumidify without the need for cooling. This function can be activated by setting option D:32 to 1 in the menu. With
daytime dehumidication, no water will be consumed.
If, for example, a constant air humidity and temperature are required continuously in a climatic chamber, cool at night
must be activated in the menu option D:04. By pressing and holding the M key the light cell is deactivated and by
pressing and releasing the M key a choice must be made for the night setting. (icon: sun with drops) The unit can now
cool, heat and humidify.

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)

D:01 Switching the heating elements on/off
Depending on the model, an OptiClimate has 2 or 3 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 all 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 off the
heating elements in the rooms that have to be cooled. 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 and restart the heat sources.
The safeguard does not affect the operation of the OptiClimate. However, the display will show the error message
E:15. (also see 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 is, for example, 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 room. 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.
D:05 = 0 means Pre-Heating is off. This is the default setting.
D:05 = 1 means Pre-Heating is on.
If Pre-Heating is switched on, the unit will heat the room up to the set cooling mode (day) temperature one hour before
daybreak (timer is on). At the beginning of the day, the room will be at the right temperature. Besides the advantage of
giving the day temperature a jump-start, this also prevents the cold parts of the unit from becoming wet, which reduces
or prevents mould build-up.
Note: Only works in conjunction with the timer and not in the light cell mode!
D:06 Slow cool-down (post-heating) on/off.
Slow cool-down (post-heating) can be switched on using this setting.
D:06 = 0 means Slow Cool-Down is off. This is the default setting.
D:06 = 1 means Slow Cool-Down is on.
If Slow Cool-Down is switched on, the unit will slowly cool the room until one hour after the end of the day.
Note: Only works in conjunction with the timer and not in the light cell mode!
D:07 Dual Room (cooling two rooms 12h by 12h) on/off.
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 will start to cool at 29°C and stop cooling at 27°C. To shorten the hysteresis effectively, the
resting time of the compressor should also be reduced. (D:27)

0= super dehumidication off.
1= super dehumidication on.
Inspection and 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.
