Heating/cooling units and heating only units
The unit range consists of two main versions: a heating/cooling
(EKHVX) version and a heating only (EKHVH) version.
Both versions are delivered with an integrated backup heater for
additional heating capacity during cold outdoor temperatures. The
backup heater also serves as a backup in case of malfunctioning of
the outdoor unit. The backup heater models are available for a
heating capacity of 6 and 9 kW, and – depending on the heating
capacity – for three different power supply specifications.
Domestic hot water tank (option)
An optional EKHTS* domestic hot water tank can be connected to
the indoor unit. The EKHTS* domestic hot water tank is available in
two different water capacities: 200 and 260 litre.

with wet fingers can cause electrical shock. Before
touching electrical parts, turn off all applicable power
supply.
To avoid electric shock, be sure to disconnect the power
supply 1 minute or more before servicing the electrical
parts. Even after 1 minute, always measure the voltage at
the terminals of main circuit capacitors or electrical parts
and, before touching, be sure that those voltages are
50 V DC or less.
When service panels are removed, live parts can easily be
touched by accident. Never leave the unit unattended
during installation or servicing when the service panel is
removed.
DANGER: DO NOT TOUCH PIPING AND INTERNAL
PARTS
Do not touch the refrigerant piping, water piping or internal
parts during and immediately after operation. The piping
and internal parts may be hot or cold depending on the
working condition of the unit.
Your hand may suffer burns or frostbite if you touch the
piping or internal parts. To avoid injury, give the piping and
internal parts time to return to normal temperature or, if
you must touch them, be sure to wear protective gloves.
WARNING
■Never directly touch any accidental leaking
refrigerant. This could result in severe wounds caused
by frostbite.
■Do not touch the refrigerant pipes during and
immediately after operation as the refrigerant pipes
may be hot or cold, depending on the condition of the
refrigerant flowing through the refrigerant piping,
compressor, and other refrigerant cycle parts. Your

4. OPERATING THE UNIT
4.1. Introduction
The heat pump system is designed to provide you a comfortable
indoor climate for many years at low energy consumption.
To get the most comfort with the lowest energy consumption out of
your system, it is very important to observe the items listed below.
Defining possible schedule timer actions for each day and filling out
the form at the very end of this manual can help you minimize the
energy consumption. Ask your installer for support if required.
■Make sure the heat pump system works at the lowest possible
hot water temperature required to heat your house.
To optimize this, make sure the weather dependent set point is
used and configured to match the installation environment.
Refer to "Field settings" on page 12.
■It is advised to install the room thermostat connected to the
indoor unit. This will prevent excessive space heating and will
stop the outdoor unit and the indoor circulation pump when the
room temperature is above the thermostat set point.
■Next recommendations only apply to installations with an
optional domestic hot water tank.
■Make sure the domestic hot water is only heated up to the
domestic hot water temperature you require.
Start with a low domestic hot water temperature set point
(e.g. 45°C), and only increase if you feel that the domestic
hot water supply temperature is not sufficient.
■If the domestic hot water is not used for two weeks or more, a
quantity of hydrogen gas which is highly flammable may
accumulate in the domestic hot water tank. To dissipate this
gas safely, it is recommended that a hot tap be turned on for
several minutes at a sink, basin, or bath, but not at a
dishwasher, clothes washer or other appliance. During this
procedure there must be no smoking, open flame or any
electrical appliance operating nearby. If hydrogen is
discharged through the tap, it will probably make a sound as
of air escaping.
4.2. Operating the digital controller
Operating the EKHV* unit comes down to operating the digital
controller.
Features and functions
The digital controller is a state of the art controller that offers full
control over your installation. It can control a heating/cooling and a
heating only installation.
Both installations are available in multiple versions which vary in
capacity, electrical supply and installed equipment (with an optional
domestic hot water tank without a booster heater).
Basic controller functions
The basic controller functions are:
■Turning the unit ON/OFF.
■Operation mode change-over:
- space heating (refer to page 5),
- space cooling (refer to page 6) (*),
- domestic water heating (refer to page 6) (*).
■Selection of features:
- quiet mode (refer to page 6),
- weather dependent control (refer to page 7).
■Temperature set point adjustment (refer to page 6).
The digital controller supports a power cut off of maximum 2 hours.
When autorestart is enabled (see "Field settings" on page 12) this
allows a power supply shut down of 2 hours without user intervention
(e.g. benefit kWh rate power supply).
Clock function
The clock functions are:
■24 hour real time clock,
■day of the week indicator.
Schedule timer function
The schedule timer function allows the user to schedule the operation
of the installation according to a daily or a weekly program.
CAUTION
Never let the digital controller get wet. This may cause an
electric shock or fire.
Never press the buttons of the digital controller with a hard,
pointed object. This may damage the digital controller.
Never inspect or service the digital controller yourself, ask
a qualified service person to do this.
■Descriptions in this manual that apply to a specific
installation or that depend on the installed equipment,
are marked with an asterisk (*).
■Some functions described in this manual may not be
available or should not be available. Ask your installer
or your local dealer for more information on
permission levels.
(*) The functions 'space cooling' and 'domestic water
heating' can only be selected when the corresponding
equipment is installed.

Space cooling operation (c)
In this mode, cooling will be activated as required by the water
temperature set point.
Domestic water heating operation (w)
In this mode, the indoor unit will heat up the domestic hot water tank.
There are several modes for heating up the domestic water tank:
1. Storage
• Scheduled
The unit will heat up the domestic water tank starting from a
scheduled time and untill the domestic hot water set point is
reached. Preferally this is done during nighttime when space
heating demand is the lowest (and if applicable, electric
tariffs are low).
• Powerful
The unit will immediately heat up the domestic water tank
untill domestic hot water storage set point upon user request.
2. Reheat
• Scheduled
The unit will heat up the domestic water tank starting from a
scheduled time and untill the reheat set point is reached.
Preferally this is done during the time of day when space
heating demand is lowest.
• Continuous
The unit will continuously heat up the domestic water tank
untill the reheat set point is reached. In this case a balance
with the space heating demand is made, which ever demand
is higher.
Quiet mode operation (s)
Quiet mode operation means that the outdoor unit works at reduced
capacity so that the sound produced by the outdoor unit drops. This
implies that the indoor heating and cooling capacity will also drop.
Beware of this when a certain level of heating is required indoors.
4.6. Controller operations
Manual operation
In manual operation, the user manually controls the settings of the
installation. The last setting remains active until the user changes it or
until the schedule timer forces another setting (refer to "Schedule
timer operation" on page 7).
As the controller can be used for a wide variety of installations, it is
possible to select a function which is not available on your
installation. In that case the message nwill appear.
Switching on and setting space heating (h) and space cooling
(c)
1Use the =button to select space heating (h) or space cooling
(c).
Icon hor cappears on the display as well as the corresponding
water temperature set point.
2Use the bi and bj buttons to set the desired water
temperature.
• Temperature range for heating: 25°C to 55°C
The temperature for heating can be set as low as 15°C (see
"Field settings" on page 12). However, the temperature for
heating should only be set lower than 25°C during
commissioning of the installation. When set lower than 25°C,
only the backup heater will operate.
In order to avoid overheating, space heating is not operable
when the outdoor ambient temperature rises above a certain
temperature (as set through field setting [4-02], refer to "Field
settings" on page 12).
• Temperature range for cooling: 5°C to 22°C
3Switch on the unit by pushing the ybutton.
The operation LED 0lights up.
■The space cooling temperature set point can only be
set manually (refer to "Manual operation" on page 6).
■Switching between space heating and space cooling
operation can only be done by pressing the =
button or by the external room thermostat.
■Space cooling operation is not possible if the
installation is a "heating only" installation.
■For purpose and configuration refer to "Field settings"
on page 12.
■The domestic hot water water temperature set storage
point can only be set manually (refer to "Manual
operation" on page 6).
■Any domestic water heating operation is impossible
when the domestic hot water tank is not installed.
■When the wicon is blinking, the domestic hot water is
heating up by the solar kit option and not by the indoor
unit. Refer to installation manual of the EKSOLHT
solar kit.
The actual operation range depends on the values set on
field setting [9].
These values shall be determined based on the
application.
In heating mode (h), the water temperature set point can
also be weather dependent (icon ais shown).
This means that the controller calculates the water
temperature set point based on the outdoor temperature.
In this case, instead of showing the water temperature set
point, the controller shows the "shift value" which can be
set by the user. This shift value 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.
When the unit is connected to an external room
thermostat, buttons =and yare not operable and the
icon eis shown. In this case, the external room
thermostat switches the unit on or off and determines the
operation mode (space heating or space cooling).

Schedule timer operation
In schedule timer operation, the installation is controlled by the
schedule timer. The actions programmed in the schedule timer will be
executed automatically.
The schedule timer always follows the last command until a new
command is given. This means that the user can temporarily overrule
the last executed programmed command by manual operation (Refer
to "Manual operation" on page 6). The schedule timer will regain
control over the installation as soon as the next programmed
command of the schedule timer occurs.
The schedule timer is enabled (picon displayed) or disabled (picon
not displayed), by pressing the pr button.
To set up the SCHEDULE TIMER refer to chapter "Programming and
consulting the schedule timer" on page 8.
What can the schedule timer do?
The schedule timer allows the programming of:
1. Space heating (refer to "Programming space heating or
domestic water heating" on page 9)
Switch on the desired mode at a scheduled time, in combination
with a set point (weather dependent or manually set).
Four actions per weekday can be programmed, totalling
28 actions.
2. Space cooling (refer to "Programming space cooling or quiet
mode" on page 10).
Switch on the desired mode at a scheduled time, in combination
with a set point (weather dependent or manually set). Four
actions can be programmed. These actions are repeated daily.
3. Quiet mode (refer to "Programming space cooling or quiet
mode" on page 10)
Switch the mode on or off at a scheduled time. Four actions can
be programmed per mode. These actions are repeated daily.
Remark that pushing the ybutton has no influence on
the domestic water heating. Domestic water heating is only
switched on or off by means of the vbutton.
Flashing icon(s) Meaning
hor cThe entering water temperature

uThe outdoor temperature
wThe domestic hot water temperature
■Only use the pr button to enable or disable the
schedule timer. The schedule timer overrules the y
button. The ybutton only overrules the schedule
timer until the next programmed action.
■If the auto restart function is disabled, the schedule
timer will not be activated when power returns to the
unit after a power supply failure. Press the pr button
to enable the schedule timer again.
■When power returns after a power supply failure, the
auto restart function reapplies the user interface
settings at the time of the power supply failure.
It is therefore recommended to leave the auto restart
function enabled.
■The programmed schedule is time driven. Therefore, it
is essential to set the clock and the day of the week
correctly. Refer to "Setting the clock" on page 5.
■Manually adjust the clock for summertime and
wintertime. Refer to "Setting the clock" on page 5.
■A power failure exceeding 2 hours will reset the clock
and the day of the week. The schedule timer will
continue operation, but with a disordered clock. Refer
to "Setting the clock" on page 5 to adjust the clock and
the day of the week.
■The actions programmed in the schedule timer will not
be lost after a power failure so that reprogramming the
schedule timer is not required.
When the unit is connected to an external room
thermostat, the schedule timer for space heating and
space cooling is overruled by the external room
thermostat.

4. Domestic water heating (refer to "Programming space heating or
domestic water heating" on page 9)
Switch the mode on or off at a scheduled time. The switch set to
on means enabeling the programmed storage and reheat
operation. Four actions per weekday can be programmed,
totalling 28 actions.
What can the schedule timer NOT do?
The schedule timer can not change the operation mode from space
cooling to space heating or vice versa.
How to interpret the programmed actions
To be able to understand the behaviour of your installation when the
schedule timer is enabled, it is important to keep in mind that the
"last" programmed command overruled 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 "Consulting
programmed actions" on page 10.
4.7. Programming and consulting the schedule timer
Getting started
Programming the schedule timer is flexible (you can add, remove or
alter programmed actions whenever required) and straightforward
(programming steps are limited to a minimum). However, before
programming the schedule timer, remind:
■Familiarise yourself with the icons and the buttons.You will need
them when programming. Refer to "Name and function of
buttons and icons" on page 4.
■Fill out the form at the very end of this manual. This form can
help you define the required actions for each day. Keep in mind
that:
- In the space heating and domestic water heating program,
four actions can be programmed per weekday. The same
actions are repeated on a weekly basis.
- In the space cooling and quiet mode program, four actions
can be programmed per mode. The same actions are
repeated on a daily basis.
■Take your time to enter all data accurately.
■Try to program the actions in a chronological way: start with
action 1 for the first action and end with the highest number for
the last action. This is not a requirement but will simplify the
interpretation of the program later.
■If 2 or more actions are programmed for the same day and at the
same time, only the action with the highest action number will be
executed.
■You can always alter, add or remove the programmed actions
later.
■The programmed actions are not stored according to
their timing but according to the time of programming.
This means that the action that was programmed first
gets action number 1, even though it is executed after
other programmed action numbers.
■When the schedule timer switches space heating or
space cooling x, the controller will also be
switched off. Note that this has no influence on
domestic water heating.
■In case no domestic water heating actions are
programmed, enabling or disabling the schedule timer
will only have influence on the space heating, cooling
and quite mode. In this way it is possible to separate
on one hand the space heating, cooling and quite
mode scheduled action as part of the schedule timer
and on the other hand the storage and reheat
operation of the domestic water heating.
In this way, it is easy to disable the space heating and
cooling by disabling the schedule timer with keeping
the storage and reheat domestic water heating
enabled (refer to "Scheduled domestic hot water
storage" on page 15 and "Scheduled/continuous
domestic hot water reheat" on page 15).
During schedule timer operation, someone may have
altered the actual settings manually (in other words, the
"last" command was overruled manually). The icon p,
indicating the schedule timer operation, may still be
displayed, giving the impression that the "last" command
settings are still active. The "next" programmed command
will overrule the altered settings and return to the original
program.

Detailed description
[0] User permission level
If required, certain user interface buttons can be made unavailable for
the user.
Three permission levels are defined (see the table below). Switching
between level 1 and level 2/3 is done by simultaneously pressing
buttons pfi and pfj immediately followed by
simultaneously pressing buttons sand ba, and keeping all 4
buttons pressed for at least 5 seconds (in normal mode). Note that no
indication on the user interface is given. When level 2/3 is selected,
the actual permission level – either level 2 or level 3 – is determined
by the field setting [0-00].
[1] Weather dependent set point (heating operation only)
The weather dependent set point field settings define the parameters
for the weather dependent operation of the unit. When weather
dependent operation is active the water temperature is determined
automatically depending on the outdoor temperature: colder outdoor
temperatures will result in warmer water and vice versa. During
weather dependent operation, the user has the possibility to shift up
or down the target water temperature by a maximum of 5°C.
■Field settings for heating operation
■[1-00] Low ambient temperature (Lo_A): low outdoor
temperature.
■[1-01] High ambient temperature (Hi_A): high outdoor
temperature.
■[1-02] Set point at low ambient temperature (Lo_Ti): the
target outgoing water temperature when the outdoor
temperature equals or drops below the low ambient
temperature (Lo_A).
Note that the Lo_Ti value should be higher than Hi_Ti, as for
colder outdoor temperatures (i.e. Lo_A) warmer water is
required.
■[1-03] Set point at high ambient temperature (Hi_Ti): the
target outgoing water temperature when the outdoor
temperature equals or rises above the high ambient
temperature (Hi_A).
Note that the Hi_Ti value should be
lower than Lo_Ti, as for
warmer outdoor temperatures (i.e. Hi_A) less warm water
suffices.
■Field settings for cooling operation
■[1-05] Weather dependent for cooling function enable (1)/

■[1-08] Set point at low ambient temperature (Lo2_Ti): the
target outgoing water temperature when the outdoor
temperature equals or drops below the low ambient
temperature (Lo2_A).
Note that the Lo2_Ti value should be higher than Hi2_Ti, as
for colder outdoor temperatures (i.e. Lo2_A) warmer water is
required.

■Make sure the domestic water is only heated up to the
domestic hot water temperature you require.
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 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 scheduled
reheat during daytime can be set.
CAUTION
■In case of a floor heating application, it is important to
limit the maximum leaving water temperature at
heating operation according to the specifications of
the floor heating installation.
■In case of a floor cooling application, it is important to
limit the minimum leaving water temperature at
cooling operation (field setting of parameter [9-03]) to
16~18°C to prevent condensation on the floor.

schedule timer. When setback is active, the scheduled
space heating set point will be lowered with the [9-08]
leaving water setback value.
Pay attention not to set the setback value too low,
especially during colder periods (e.g. winter time). It is
possible that the room temperature can not be reached (or
it will take a much longer time) because of the big
temperature difference.

6. MAINTENANCE
6.1. Important information regarding the refrigerant
used
This product contains fluorinated greenhouse gases covered by the
Kyoto Protocol.
Refrigerant type: R410A
GWP(1) value: 1975
(1) GWP = global warming potential
Periodical inspections for refrigerant leaks may be required
depending on European or local legislation. Please contact your local
dealer for more information.
6.2. Maintenance activities
In order to ensure optimal availability of the unit, a number of checks
and inspections on the unit and the field wiring have to be carried out
at regular intervals, preferably yearly. This maintenance should be
carried out by your local Daikin technician (see installation manual).
The only maintenance which may be required by the operator is:
■keeping the remote controller clean by means of a soft damp
cloth,
■checking if the water pressure indicated on the manometer is
above 1 bar.
Only for the optional domestic hot water tank:
■A check for correct operation of the pressure relief valve
installed on your domestic hot water tank, has to be carried out
at least every 6 months: it is important that the lever on the valve
is actuated to prevent accumulation of mineral deposits that may
impair valve operation and to confirm that the valve and
discharge pipe are not blocked. The lever should be operated
slowly and smoothly to avoid a sudden rush of hot water from
the discharge pipe.
Failure to operate the relief valve actuating lever may result in
the water heater exploding.
■Continuous leakage of water from the discharge pipe may
indicate a problem with the water heater.
■If a discharge pipe is connected to the pressure relief device it
must be installed in a continuously downward direction and in a
frost-free environment. It must be left open to the atmosphere.
6.3. Standstill
7. TROUBLESHOOTING
The guidelines below might help to solve your problem. If you cannot
solve the problem, consult your installer.
8. DISPOSAL REQUIREMENTS
Dismantling of the unit, treatment of the refrigerant, of oil and of other
parts must be done in accordance with relevant local and national
legislation.
Your product is marked with this symbol. This means that
electrical and electronic products shall not be mixed with
unsorted household waste.
Do not try to dismantle the system yourself: the dismantling of the
system, treatment of the refrigerant, of oil and other parts must be
done by a qualified installer in accordance with relevant local and
national legislation.
Units must be treated at a specialized treatment facility for re-use,
recycling and recovery. By ensuring this product is disposed off
correctly, you will help to prevent potential negative consequences for
the environment and human health. Please contact the installer or
local authority for more information.
DANGER
■Do not touch water pipes during and immediately after
operation as the pipes may be hot. Your hand may
suffer burns. To avoid injury, give the piping time to
return to normal temperature or be sure to wear
proper gloves.
■Do not touch any switch with wet fingers. Touching a
switch with wet fingers can cause electrical shock.
WARNING
Do not touch the refrigerant pipes during and immediately
after operation as the refrigerant pipes may be hot or cold,
depending on the condition of the refrigerant flowing
through the refrigerant piping, compressor, and other
refrigerant cycle parts. Your hands may suffer burns or
frostbite if you touch the refrigerant pipes. To avoid injury,
give the pipes time to return to normal temperature or, if
you must touch them, be sure to wear proper gloves.
CAUTION
If the supply cord is damaged, it must be replaced by the
manufacturer, its agent or similar qualified persons in order
to avoid hazards.
CAUTION
During longer periods of standstill, e.g. during summer with
a heating only application, it is very important NOT TO
SWITCH OFF THE POWER SUPPLY towards the unit.
Switching off the power supply stops the automatic
repetitive movement of the pump in order to prevent it from
getting jammed.
POSSIBLE CAUSES CORRECTIVE ACTIONS
