INTRODUCTION
General information
Thank you for purchasing this Daikin indoor unit.
The unit is the indoor part of the air to water ERSQ or ERRQ heat
pump. The unit is designed for floor standing indoor installation and
used for heating applications. The unit can be combined with space
heating radiators (field supply) and with an EKHTS* domestic hot
water tank (option).
A remote controller with room thermostat functionality is standard
supplied with this unit to control your installation.
NOTE
An EKHBRD indoor unit can only be connected to an
outdoor ERSQ or ERRQ-unit.
Domestic hot water tank (option)
An optional EKHTS* domestic hot water tank can be connected to
the indoor unit. The domestic hot water tank is available in two
different water capacities: 200 and 260 litre.
Refer to the domestic hot water tank installation manual for further
details.
Remote controller (option)
An optional secondary EKRUAHTA remote controller (with room
thermostat functionality) can be connected to the indoor unit.
Purpose is to provide the possibility to install the standard remote
controller near the unit (for service reasons), and install another
remote controller in another place (e.g. living room) to operate your
installation.
Refer to the "Installation of the remote controller" on page 15 for
further details.

The remote controller gives immediate feedback to the indoor unit
and by doing so it matches in a smart way the unit performance to
the demanded space heating requirements. In this way there is no
frequent start/stop of the unit or there are no too big temperature
fluctuations in the to be heated rooms. This remote controller has
also a smart logic functionality which controls the combined space
heating and domestic hot water demand (e.g. if room temperature
drops more than 3°C during domestic hot water operation, the unit
will automatically switch back to space heating). There is no remote
controller near the unit. During service maintenance an additional
remote controller can be connected by a service person.

Indoor unit for air to water heat pump system

Application 4
Pattern B
Space heating provided through floor heating loops. For floor heating
applications in combination with radiators the water temperature
delivered by the Daikin system is too high. For this reason a
temperature reducing device (field supply) is required to lower the
water temperature (the hot water will be mixed with cold water to
lower the temperature). The control of this field supplied feature is not
done by the heat pump system. The operation and configuration of
the field water circuit is the responsibility of the installer. Daikin only
offers the possibility to have multiple set points on request.
The domestic hot water tank is installed in a separate circuit (with a
3-way valve) of the temperature reducing device(s). This
configuration does not allow simultaneous domestic hot water and
space heating operation.

The domestic hot water tank is installed in parallel with the mixing

Field wiring
Space heating with an auxiliary boiler (alternating operation)
L
th
Space heating application by either the Daikin indoor unit or by an
auxiliary boiler connected in the system. An auxiliary contact decides
whether either the EKHBRD* indoor unit or the boiler will operate.
This auxiliary contact can e.g. be an outdoor temperature thermostat,
an electricity tariff contact, a manually operated contact, etc.
Bivalent operation is only possible for space heating operation, not
for the domestic hot water heating operation. Domestic hot water in
such an application is always provided by the domestic hot water
tank which is connected to the Daikin indoor unit.
The auxiliary boiler must be integrated in the piping work and in the
field wiring according to the illustrations below.
■
Be sure that the boiler and the integration of the boiler
in the system is in accordance with relevant European
and national regulations.
■
Daikin can not be put responsible for incorrect or
unsafe situations in the boiler system.

■
During heating operation of the EKHBRD* unit,
the unit will operate so as to achieve the target
leaving water temperature as set on the user
interface. When weather dependent operation is
active, the water temperature is determined
automatically depending on the outdoor
temperature.
During heating operation of the boiler, the boiler
will operate so as to achieve the target leaving
water temperature as set on the boiler controller.
Never set the target leaving water temperature set
point on the boiler controller above 80°C.
Make sure that return water to the EKHBRD* heat
exchanger never exceeds 80°C.
For this reason, never put the target leaving water
temperature set point on the boiler controller above 80°C
and install an aquastat(a) valve in the return water flow of
the EKHBRD* unit.
Make sure that the non-return valves (field supply) are
correctly installed in the system.
Make sure that the room thermostat (th) is not frequently
turned ON/OFF.
Daikin shall not be held liable for any damage resulting
from failure to observe this rule.
(a) The aquastat valve must be set for 80°C and must operate to close the return
water flow to the unit when the measured temperature exceeds 80°C. When the
temperature drops to a lower level, the aquastat valve must operate to open the
return water flow to the EKHBRD* unit again.

Result:

■
■
■
Since 380 l is higher than 180 l or 270 l, the pre-pressure must
be decreased (see table above).
The required pre-pressure is:
Pg=(H/10+0.3) bar=(0/10+0.3) bar=0.3 bar
The corresponding maximum water volume can be read from
the graph: approximately 380 l for leaving water of 65°C and
approximately 250 l for leaving water of 80°C.
In case of 65°C leaving water, since the total water volume
(380 l) is not higher than the maximum water volume (380 l), the
expansion vessel suffices for the installation.
In case of 80°C leaving water, because the total water volume
(380 l) is higher than the maximum water volume (250 l) of the
expansion vessel, an additional expansion vessel must be
installed.
Precautions when connecting field piping and regarding
insulation
The complete water circuit, inclusive all piping, must be insulated to
prevent reduction of the heating capacity.
If the indoor ambient temperature is higher than 30°C and the
humidity is higher than RH 80% then the thickness of the insulation
materials should be at least 20 mm in order to avoid condensation on
the surface of the insulation.
CHARGING
WATER
Method for adding water
Setting the pre-pressure of the expansion vessel
When it is required to change the default pre-pressure of the
expansion vessel (1 bar), keep in mind the following guidelines:
■
■
Use only dry nitrogen to set the expansion vessel pre-pressure.
Inappropriate setting of the expansion vessel pre-pressure will
lead to malfunction of the system. Therefore, the pre-pressure
should only be adjusted by a licensed installer.
To be able setting the pre-pressure of the expansion vessel, the
switch box needs to be removed from the unit. How this must be done
is explained in the chapter "Opening the unit" on page 31.
1
Connect the water supply to a fill valve (field supply).
2
Make sure the automatic air purge valve is open (at least 2
turns).
3
Fill with water until the manometer indicates a pressure of
approximately 2.0 bar. Remove air in the circuit as much as
possible using the air purge valves.
NOTE
■
During filling, it might not be possible to remove all
air in the system. Remaining air will be removed
through the automatic air purge valves during first
operating hours of the system. Additional filling
with water afterwards might be required.
■
The water pressure indicated on the manometer
will vary depending on the water temperature
(higher pressure at higher water temperature).
However, at all times water pressure should
remain above 0.3 bar to avoid air entering the
circuit.
■
The unit might dispose some excessive water
through the pressure relief valve.
■
Water quality must be according to EU directive
98/83 EC.
Connecting the water circuit
Water connections must be made. The location of the water inlet
connection and the water outlet connection on the indoor unit is
shown in the chapter "Main components" on page 6.
Be careful not to deform the unit piping by using excessive
force when connecting the piping. Deformation of the
piping can cause the unit to malfunction.
If air, moisture or dust gets in the water circuit, problems may occur.
Therefore, always take into account the following when connecting
the water circuit:
■
■
■
■
■
■
Use clean pipes only.
Hold the pipe end downwards when removing burrs.
Cover the pipe end when inserting it through a wall so that no
dust and dirt enter.
Use a good thread sealant for the sealing of the connections.
When using non-brass metallic piping, make sure to insulate
both materials from each other to prevent galvanic corrosion.
Because brass is a soft material, use appropriate tooling for
connecting the water circuit. Inappropriate tooling will cause
damage to the pipes.
■
■
NOTE
The unit is only to be used in a closed water system.
Application in an open water circuit can lead to
excessive corrosion of the water piping.
Never use Zn-coated parts in the water circuit.
Excessive corrosion of these parts may occur as
copper piping is used in the unit's internal water
circuit.
When using a 3-way valve or a 2-way valve in the
water circuit, the maximum changeover time of the
valve shall be less than 60 seconds.

abbreviations used are listed below.
switch box components list
WARNING
■
A main switch or other means for disconnection,
having a contact separation in all poles, must be
incorporated in the fixed wiring in accordance with
relevant local and national regulations.
■
Switch off the power supply before making any
connections.
■
Use only copper wires.
■
All field wiring and components must be installed by a
licensed electrician and must comply with relevant
European and national regulations.
■
Be sure to install the required fuses as mentioned on
the electrical wiring diagram.
■
The field wiring must be carried out in accordance
with the wiring diagram supplied with the unit and the
instructions given below.
■
Never squeeze bundled cables and make sure that it
does not come in contact with the piping and sharp
edges.
Make sure no external pressure is applied to the
terminal connections.
■
Be sure to use a dedicated power supply. Never use a
power supply shared by another appliance.
■
Be sure to establish an earth. Do not earth the unit to
a utility pipe, surge absorber, or telephone earth.
Incomplete earth may cause electrical shock.
■
Be sure to install an earth leakage protector in
accordance with relevant local and national
regulations. Failure to do so may cause electrical
shock.
When installing the earth leakage protector make
sure that it is compatible with the inverter (resistant to
high frequency electrical noise) to avoid unnecessary
opening of the earth leakage protector.
■
As this unit is equipped with an inverter, installing a
phase advancing capacitor not only will deteriorate
power factor improvement effect, but also may cause
capacitor abnormal heating accident due to highfrequency waves. Therefore, never install a phase
advancing capacitor.
■
Be sure that after installation work all the rubber
bushings are put back in place to protect the wires
from touching sharp edges.

Consult with the electricity company acting as provider at the site
where this equipment is to be installed to know whether it is
appropriate to connect the equipment in one of the benefit kWh rate
power supply delivery systems available, if any.
When the equipment is connected to such benefit kWh rate power
supply, the electricity company is allowed to:
■
interrupt power supply to the equipment for certain periods of
time;
■ demand that the equipment only consumes a limited amount of
electricity during certain periods of time.
The indoor unit is designed to receive an input signal by which the
unit switches into forced off mode. At that moment, the unit
compressors will not operate.

turned on, "88" is displayed on the remote controller during its
initialization, which might take up to 30 seconds. During this process
the remote controller can not be operated.
Field settings
The indoor unit should be configured by the installer to match the
installation environment (outdoor climate, installed options, etc.) and
user demand. Thereto, a number of so called field settings are
available. These field settings are accessible and programmable
through the user interface on the indoor unit.
Each field setting is assigned a 3-digit number or code, for example
[5-03], which is indicated on the user interface display. The first digit
[5] indicates the 'first code' or field setting group. The second and
third digit [03] together indicate the 'second code'.
A list of all field settings and default values is given in the "Field
settings table" on page 28. In this list we provided for 2 columns to
register the date and value of altered field settings at variance with

5
Save the new value by pressing the pr button.
6
Repeat step 2 through 4 to change other field settings as
required.
7
When finished, press the z button to exit FIELD SET MODE.
NOTE
NOTE
Changes made to a specific field setting are only
stored when the pr button is pressed. Navigating to a
new field setting code or pressing the z button will
discard the change made.
■
■
NOTE
Once the field setting is set, the chosen permission level is not
yet active. Enabling the selected permission level is done by
simultaneously pressing buttons pi and pj immediately
followed by simultaneously pressing buttons s and ba, and
keeping all 4 buttons pressed for at least 5 seconds. Note that
no indication on the remote controller is given. After the
procedure the blocked buttons will not be available anymore.
Deactivating the selected permission level is done on the same
way.
■
If needed, it is possible to adjust some thermistor value of the
unit by a correction value. This can be used as countermeasure
for thermistor tolerances or capacity shortage.
Before shipping, the set values have been set as
shown under "Field settings table" on page 28.
The compensated temperature (= measured temperature plus
compensation value) is then used for controlling the system and
will be displayed in the temperature read-out mode. See also
"[9] Automatic temperature compensation" on page 22 for
compensation values for leaving water temperature and
domestic hot water temperature.
When exiting FIELD SET MODE, "88" may be
displayed on the remote controller LCD while the
unit initializes itself.
When running through the field settings you may
notice that there are some more field settings as there
are mentioned in the "Field settings table" on page 28.
These field settings are not applicable and may not
be changed!
[0-01] Room temperature compensation value
■
[0-03] Status: defines whether the ON/OFF instruction can be
used in the schedule timer for space heating.
The schedule timer for space heating can be programmed on 2
different ways: based on the temperature set point (both leaving
water temperature and room temperature) and based on the
ON/OFF instruction.
NOTE
By default space heating based on temperature set
point (method 1) is enabled, so only temperature shifts
are possible (no ON/OFF instruction).
Advantage of this method is that you can simply switch
off the space heating operation by pushing the y
button without disabling the automatic domestic hot
water storage operation (e.g. during summertime
when no space heating is required).

In the following tables both methods on how to interpret the schedule
timer are shown.
Method 1
Space heating based on temperature set point (a)
During operation
During schedule timer operation the operation LED is lit
continuously.
When pushing
the y button
The schedule timer for space heating will stop and will
not start again.
The controller will be switched off (operation LED will
stop working).
However, the schedule timer icon will stay displayed
which means that the domestic water heating stays
enabled.
When pushing
the r/p button
The schedule timer for space heating and domestic
water heating along with the quiet mode will be stopped
and will not start again.
The schedule timer icon will not be displayed anymore.
Method 2
Space heating based on ON/OFF instruction
During operation
When the schedule timer switches space heating OFF,
the controller will be switched off (operation LED will stop
working). Note that this has no influence on the domestic
water heating.
When pushing
the y button
The schedule timer for space heating will stop (when
active at that moment) and will start again at the next
scheduled ON function.
The "last" programmed command overrules the
"preceding" programmed command and will remain
active until the "next" programmed command occurs.
Example: imagine the actual time is 17:30 and actions
are programmed at 13:00, 16:00 and 19:00. The "last"
programmed command (16:00) overruled the
"previous" programmed command (13:00) and will
remain active until the "next" programmed command
(19:00) occurs.
So in order to know the actual setting, one should consult
the last programmed command. It is clear that the "last"
programmed command may date from the day before.
Refer to the operation manual.
The controller will be switched off (operation LED will
stop working).
However the schedule timer icon will stay displayed
which means that the domestic heating stays enabled.
When pushing
the r/p button
The schedule timer for space heating and domestic
water heating along with the quiet mode will be stopped
and will not start again.
The schedule timer icon will not be displayed anymore.

[1] Automatic storage timing for domestic water heating
In this mode, the indoor unit will deliver hot water to the domestic hot
water tank based on the daily fixed pattern. This mode will continue
until storage temperature is reached.
Automatic storage is the advised domestic hot water mode. In this
mode water heats up during the night (when space heating
requirements are lower) until the storage set point. The heated water
is stored in the domestic hot water tank at a higher temperature so it
can fulfil the domestic hot water requirements throughout the day.
Setback can be configured for both room temperature control and
leaving water temperature control.

Start with a low domestic hot water storage
temperature set point, and only increase if you
feel that the domestic hot water supply
temperature is not sufficient for your needs (this
depends on your water using pattern).
■
■
Make sure the domestic hot water is not heated
unnecessary. Start with activating automatic
storage during night (default setting). If it seems
that the domestic hot water night storage
operation is not sufficient for your needs, an
additional storage during daytime can be set.
For energy-saving purposes, it is advised to
enable the weather dependent domestic water
heating. Refer to setting "[b-02]" on page 23.
Refer to "[b] Domestic hot water set points" on page 22 for
temperature set points.
[2] Automatic setback function
Setback function provides the possibility to lower the room
temperature. The setback function can for instance be activated
during the night because the temperature demands during night and
day are not the same.

It is advised to set the start time of automatic storage during night
[1-01] on the moment that the setback function starts [2-01].
Refer to "[5] Automatic setback and disinfection set point" on page 21
for temperature set points.
[3] Weather dependent set point
When weather dependent operation is active, the leaving water
temperature is determined automatically depending on the outdoor
temperature: colder outdoor temperatures will result in warmer water
and vice versa. The unit has a floating set point. Activating this
operation will result in a lower power consumption than use with a
manually fixed leaving water set point.
During weather dependent operation, the user has the possibility to
shift up or down the target water temperature by a maximum of 5°C.
This "
" is the temperature difference between the
temperature set point calculated by the controller and the real set
point. E.g. a positive shift value means that the real temperature set
point will be higher than the calculated set point.
It is advised to use the weather dependent set point because it
adjusts the water temperature to the actual needs for space heating.
It will prevent the unit from switching too much between thermo ON
operation and thermo OFF operation when using the remote
controller room thermostat or external room thermostat.

■
The external room thermostat only gives an ON/OFF signal to
the heat pump based on the room temperature. Because it does
not give continuous feedback information to the heat pump, it is
supplementary to the remote controller room thermostat
function. To have a good control of the system and avoiding
frequent ON/OFF it is advised to use the automatic weather
dependent set point operation.
Even if all schedule timers are de-activated and there is no reheat
function active, the disinfection function will operate if a domestic hot
water tank is installed and field setting [4-00] is set to ON.
Refer to "[5] Automatic setback and disinfection set point" for
temperature set points.
■
If the optional external room thermostat is installed, its operation
must be enabled by field setting. Default [6-01] = 0, which
means no external room thermostat is installed. Set [6-01] to 1 if
the optional external room thermostat is installed.
This mode will disinfect the domestic hot water tank by periodically
heating the domestic water to a specific temperature.
NOTE
When enabling the domestic hot water tank option
be aware that the advised default settings become
active:

[7-00] Bottom plate heater option
An optional bottom plate heater can be installed in your outdoor
unit. In case an ERRQ* outdoor unit (special model with
freeze-up countermeasures) is installed, the unit will have the
bottom plate heater already standard installed.
If the bottom plate heater is installed, its operation must be
enabled by field setting. Default [7-00] = 0 which means no

By changing this value the operation range for space heating
operation can be modified.
When using the remote control delivered with the unit, 2 types of
temperature control are possible. Default [8-00] = 1 which
means that the remote controller is used as room thermostat, so
the remote controller can be placed in the living room to control
the room temperature. Set [8-00] to 0 to use the unit in leaving
water temperature control.
■
If the ambient temperature becomes higher than (24°C + the
value of [9-02]) no space heating is possible.
Space heating can be requested as long as the ambient
temperature is lower than (20°C + the value of [9-02]).
Example: [9-02] = –2°C
[8-01] Auto restart
When a power failure occurred and the power returns to the unit,
the system will automatically restore it's settings and restart.

The freeze-up prevention is only active when the unit is in
thermo OFF condition. If prevention level 1 is enabled, the
freeze-up prevention will start if the outdoor ambient
temperature <4°C and if leaving or return water temperature
<7°C. For prevention level 2, the freeze-up prevention will start
as soon as the ambient temperature <4°C.
For both cases the pump will operate and if leaving or return
water <5°C for 5 minutes the unit will start up to prevent too low
temperatures.
It is advised to enable freeze-up prevention if the indoor unit is
located in a colder ambient room (e.g. garage, ...) to prevent
water freeze-up.
[9] Automatic temperature compensation
If needed, it is possible to adjust some thermistor value of the unit by
a correction value. This can be used as countermeasure for
thermistor tolerances or capacity shortage.
The compensated temperature (= measured temperature plus

If enabled, the storage set point will be set weather dependent.
When recovering/vacuuming of the indoor unit is needed, field
setting [E-00] can be activated. It will force the unit into thermo
OFF and will open the expansion valve of the indoor unit R134a
circuit so full vacuuming is possible.
In case of a higher ambient temperature (e.g. during summertime), the cold supply water to the mixing tap (e.g. shower, bath)
will also have a higher temperature. This makes that the
temperature of the hot water from the domestic hot water tank
may be lower to reach the same water mixing temperature from
the shower or bath mixing tap. In this way, with a lower domestic
hot water tank temperature setting the comfort level can be kept
the same but with a lower energy consumption.
By default [E-00] = 0, set to 1 to enable the vacuum mode.

Multiple set point control
When requesting space heating and domestic water heating
(storage) at the same time, domestic water will be heated, but as
soon as the room temperature drops 3°C from set point, space
heating will start till 0.5°C above set point, then domestic water
will be heated again till storage set point.
If you want to use multiple set point control, a temperature reducing
device (
) is needed. The temperature reducing device converts
the high inlet water temperature to a reduced water outlet
temperature which will be delivered to the appliance(s).

When temperature reducing devices are installed, the system can be
configured to use multiple water set points.
The water set points can be selected in function of multiple set point
operation patterns.
Below the 2 possible patterns are explained in detail.
Multiple set point control according to pattern A
During normal operation, domestic water heating and space heating
modes are separated and activated intermittent to fulfil a
simultaneous request. Therefor multiple set point pattern A can be
configured to allow simultaneous domestic water heating and space
heating operation without intermission.

■
During space heating operation, water is provided based on the
selected water temperature set point for space heating. A
shut-off valve (field supply) must be installed in the domestic hot
water tank coil circuit. The valve must be closed to protect the
domestic hot water tank from cooling down by lower temperature
water going through the coil during space heating.
■
During domestic water heating operation, the water temperature
set point is normally higher than the set point requested during
space heating operation. The valve allowing water to enter the
domestic hot water tank coil is open. The heat pump will deliver
water with a higher temperature which is needed for production
of the domestic hot water. At that time, the lower temperature
appliances have to be protected against the higher water
temperature by a temperature reducing valve.
The configuration of pattern A allows 2 space heating set points and
one (same as in the classic design) domestic hot water set point.
The request signals for space heating can be implemented in 2
different ways (installer choice):
■
thermo ON/OFF signal (from external room thermostat)
■
status signal (active/not active) from the corresponding
temperature reducing device (
)

can be controlled by the remote controller room thermostat function
or by the external room thermostat. Settings for space 0 can be made
on the remote controller (same as during normal operation (1)).
(1) When using the automatic weather dependent function for setting of space 0, you
have to make sure that the lowest possible temperature of the space 0 floating
set point (including the possible negative shift value) is higher than the
temperature set point of spaces 1 and 2.
This means that field setting [3-03] of space 0 needs to be higher than
temperature set point of spaces 1 and 2.

FINAL
CHECK AND TEST RUN
Procedure for space heating
1
Check the leaving water and entering water temperature through
the remote controller read-out mode and write down the
displayed values. See "Temperature read-out mode" on
page 30.
2
Push the z button 4 times so the t icon will be displayed.
3
Perform the test as follows (when no action is performed, the
user interface will return to normal mode after 10 seconds or by
pressing the z button once):
Final check
Before switching on the unit, read the following:
■
■
When the complete installation and all necessary settings have
been carried out, be sure that all panels of the unit are closed. Is
this not the case, inserting your hand through the remaining
openings can cause serious injury due to electrical and hot parts
inside the unit.
The service panel of the switch box may only be opened by a
licensed electrician for maintenance purposes.
To test the space heating operation push the y button to start
the test run operation.
4
The test run operation will end automatically after 30 minutes or
when reaching the set temperature. The test run operation can
be stopped manually by pressing the z button once. If there are
misconnections or malfunctions, an error code will be displayed
on the user interface. Otherwise, the user interface will return to
normal operation.
5
To resolve the error codes, see "Error codes" on page 33.
6
Check the leaving water and entering water temperature through
the remote controller read-out mode and compare them with the
values noted with step 1. After 20 minutes of operation an
increase of the values should confirm the space heating
operation.
In order to purge most of the air out of the system perform a pump
operation as described below:
1
Change field setting [E-04]
The default value is 0.
■ When changing the setting to 1, the pump will operate at low
speed (pump only, the unit will not operate).
■ When changing the field setting to 2, the pump will operate at
high speed.
2
When air purging is finished, change the field setting back to 0.
It is the responsibility of the installer to make sure that the air is
purged out of the unit and system.
Test run
The installer is obliged to verify correct operation of the indoor and
outdoor unit after installation. Therefor a test run must be performed
according to the procedures described below. At any time it is
possible to check correct operation of space heating and domestic
water heating.
During the first start up of the unit (the first 48 hours of
compressor running), it might happen that the noise
level of the unit is higher than mentioned in the
technical specifications. This is not an abnormal event.
NOTE
Push and hold the ba button for 5 seconds.
The leaving water temperature is displayed (icons l and =
and é are blinking).
It is not possible to perform a test run if a forced
operation from the outdoor unit is in progress. Should
forced operation be started during a test run, the test
run will be aborted.
Check the domestic hot water tank temperature through the
remote controller read-out mode. See "Temperature read-out
mode" on page 30.
2
Push the w button for 5 seconds.
The w icon will start blinking with 1 second intervals.
3
Keep the unit operating for 20 minutes and check the domestic
hot water tank temperature through the remote controller again.
An increase of the value with 5°C should confirm the domestic
water heating operation.
4
The operation will stop if the tank storage temperature has been
reached.
Use the pi and pj buttons to display:
•
•
•
•
3
NOTE
1
On the remote controller, the actual temperatures can be displayed.
2

General guidelines
Maintenance activities
WARNING: ELECTRIC SHOCK
■
Before carrying out any maintenance or repair activity,
always switch off the circuit breaker on the supply
panel, remove the fuses or open the protection
devices of the unit.
■
Make sure that before starting any maintenance or
repair activity, also the power supply to the outdoor
unit is switched off.
■
Do not touch live parts for 10 minutes after the power
supply is turned off because of high voltage risk.
Before starting the troubleshooting procedure, carry out a thorough
visual inspection of the unit and look for obvious defects such as
loose connections or defective wiring.
When carrying out an inspection on the switch box of the
unit, always make sure that the main switch of the unit is
switched off.
When a safety device was activated, stop the unit and find out why
the safety device was activated before resetting it. Under no
circumstances safety devices may be bridged or changed to a value
other than the factory setting. If the cause of the problem can not be
found, call your local dealer.
If the pressure relief valve is not working correctly and is to be
replaced, always reconnect the flexible hose attached to the pressure
relief valve, to avoid water dripping out of the unit!
■
Additionally, measure the points as shown in figure 5
with a tester and confirm that the voltage of the
capacitor in the main circuit is no more than 50 V DC.
■
The heater of the compressor may operate even in
stop mode.
Opening the unit
■
Please note that some sections of the electric
component box are hot.
■
■
Make sure you do not touch a conductive section.
■
