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.

WATER-SIDED CONNECTIONS WATER-SIDED CONNECTIONS

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.

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.

3) Fan speed key Fn

This key is used for selecting the air speed of the fan. The sequence is as follows:

Automatic Low Medium High

The speed changes whenever the Fn key is pressed. If you select the automatic fan mode in the Cool mode, the unit will

ventilate more or less depending on the need for cooling.

By selecting day or night with the mode key a different fan speed can be chosen for both day and night. For the night

we recommend the lowest fan speed for heating and dehumidifying. If a great deal must be dehumidied during the

night, the fan speed can be set to position 2 or 3.

PUTTING INTO OPERATION PUTTING INTO OPERATION

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





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

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





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

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.

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)

to factory settings. Conrm this with the on/off key.

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.

FAULT ANALYSIS AND ERROR MESSAGES FAULT ANALYSIS AND ERROR MESSAGES

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 (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 should probably be switched. It does not matter which ones of the three

phases are switched.

If the fuse automat burst when the unit has to start cooling, most likely a fuse of the wrong 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 apparatus while the unit is off, it might be possible that the magnetic 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 Mounting 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 = Drain 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.

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

Error 08 = Water leakage safeguard is active.

There is a water leak. Repair the leak and dry the end of the sensor.

In Dual Room systems, error 08 indicates a problem with the second temperature sensor.

Error 09 = Thermal safeguard of the compressor is activated.

The compressor consumes too much current. Contact the Technical Service department, if the thermal safeguard jumps

again after resetting. The thermal safeguard is located at the left-hand side near the printed circuit board in the electrical

compartment.

Error 10 = Anti-freeze safeguard, the temperature of the cooling block is too low.

If the cooling block is colder than 0°C, it can freeze up. The unit stops cooling and starts to defrost. Most likely too much

water ows through the unit. This causes the unit to have too much cooling capacity. The minimum pressure is 1.3MPa.

You might have to increase the pressure slightly to reduce the cooling capacity. See the Settings section to remedy this.

The dust/carbon lters may also be blocked or the outlet is too scanty/tight (too few holes or the hose is too thin). The

result is that the unit cannot get rid of its cold air.

Error 11 = Poor cooling.

There is no proper cooling. There may be a leak in the cooling system and it needs to be repaired. The condenser of

the compressor may also be faulty.

Error 12 = High pressure protection.

If this error message appears, most likely water does not ow through the unit. This should be resolved immediately,

because the unit cannot get rid of its hot air and the pressure of the cooling system will repeatedly increase too much.

It is also possible that the unit gets too little water. See the Setting the cooling capacity section (page 14) for

the correct ow.

If water does not ow through the unit and the taps and solenoid valve are open, the heat exchanger might also be

clogged due to the use of well or polluted water. Check the lter in the inlet.

Error 13 = Low pressure protection.

Check the manometer when the unit is off. Is the pressure lower than 4bar/0.4Mpa? If yes, there is a leak in the cooling

system and it must be repaired.

Error 14 = Current interruption alarm.

The unit is deprived of current. This alarm, which is only visible in the alarm history at the bottom of the display,

indicates that there was a problem with the current.

Error 15 = High ambient temperature safeguard is active.

As soon as the ambient temperature drops below the set day temperature, the unit will switch on the sources of heat

again and the error code will disappear. The number 15 will, however, continue to be shown in the log at the bottom

of the display. You can delete this by pressing and holding the Rkey.

Error 16 = Water leakage safeguard is active.

There is a leak. The external water sensor (the 5m long wire with two blank cores at the end) makes contact with water

and the water supply is closed. Once the leak is repaired, you have to press the ON/OFF key and the unit will

operate normally. Please contact your supplier in case of any other error message.

Error 17 = Intake air sensor faulty or not connected

Error 18 = Outlet air sensor faulty or not connected

Error 19 = Temperature low pressure sensor faulty or not connected
