This unit
The AD indoor unit is the indoor part of the
reversible air to water Daikin ERHQ heat pumps. These units are
designed for wall mounted indoor installation and used for both
heating and cooling applications. The units can be combined with
Daikin fan coil units, floor heating, low temperature radiators, the
Daikin domestic hot water tanks and the solar option kit.
The AD indoor unit range consists of two main
versions: a heating/cooling (EKHBX) version and a heating only
(EKHBH) 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 heaters are available in different
capacities.
NOTE
An EKHBH/XE008AA3V3 indoor unit can only be
connected to an ERHQ00*AD series outdoor unit.
NOTE
The heat pump unit is preset to a restricted power
supply condition mode. The information in this manual
is only valid in case the power supply condition is not
restricted. Refer to the chapter "Field settings" on
page 10 how to disable the restricted power supply

OPERATING THE UNIT
OPERATING
THE DIGITAL CONTROLLER
Operating the EKHB* unit comes down to operating the digital
controller.
INTRODUCTION
Never let the digital controller get wet. This may cause an
electric shock or fire.
The AD heat pump system is designed to provide
you a comfortable indoor climate for many years at low energy
consumption.
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.
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 AD 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 10.
■
Features and functions
The digital controller is a state of the art controller that offers full
control over your installation. It can control a cooling/heating and a
heating only installation.
Both installations are available in multiple versions which vary in
capacity, electrical supply and installed equipment (backup heater in
the indoor unit or a domestic hot water tank with a booster heater).
NOTE
Make sure the equilibrium temperature field setting is configured
correctly.
■
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.
Refer to "Field settings" on page 10.
This function applies to operation of the backup heater. Setting
the equilibrium temperature correctly will avoid the backup
heater to operate when the heat pump has sufficient capacity to
heat up your house.
■
■
It is advised to install a 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.
Basic controller functions
■
Turning the unit ON/OFF.
Next recommendations only apply to installations with an
optional domestic hot water tank.
■
Operation mode change-over:
- space heating (refer to page 4),
- space cooling (refer to page 5) (*),

■
Selection of features:
- quiet mode (refer to page 5),
- weather dependent control (refer to page 6).
■
Temperature set point adjustment (refer to page 5).
■ Make sure the domestic 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.
■ Make sure both the domestic water heating and booster
heating only start 1 to 2 hours before you expect domestic
hot water usage.
In case you only need a lot of domestic hot water in the
evening or in the morning, only allow domestic water heating
during early morning and early evening. Also keep hours with
low electricity cost tariffs in mind.
To do this, program both the domestic water heating and
booster heating schedule timer. Refer to Programming in
chapter "Programming and consulting the schedule timer" on
page 7.
The basic controller functions are:
NOTE
(*) The functions 'space cooling' and 'domestic water
heating' can only be selected when the corresponding
equipment is installed.

Description of the operation modes
Space heating operation (h)
In this mode, heating will be activated as required by the water
temperature set point. The set point can be set manually (refer to
"Manual operation" on page 5) or weather dependent (refer to
"Selecting weather dependent set point operation (only in heating
mode)" on page 6).
Startup (d)
At the start of a heating operation, the pump is not started until a
certain refrigerant heat exchanger temperature is reached. This
guarantees correct startup of the heat pump. During startup, icon
d is displayed.
Defrost (d)
In space heating operation or domestic water heating operation,
freezing of the outdoor heat exchanger may occur due to low outdoor
temperature. If this risk occurs, the system goes into defrost
operation. It reverses the cycle and takes heat from the indoor
system to prevent freezing of the outdoor system. After a maximum
of 8 minutes of defrost operation, the system returns to space
heating operation.
This button enables or disables quiet mode.
If the controller is set in permission level 2 or 3 (refer to "Field
settings" on page 10), the quiet mode button will not be
operable.

■
Switching between space heating and space
cooling operation can only be done by pressing
the = button or by an external room thermostat.
■
Space cooling operation is not possible if the
installation is a heating only installation.
Domestic water heating operation (w)
In this mode, the indoor unit will deliver hot water to the domestic hot
water tank when the space heating or space cooling operation has
reached its temperature set point. When necessary and when
allowed by the booster heater schedule timer (refer to "Programming
quiet mode, booster heating or domestic water heating" on page 9),
the booster heater provides auxiliary heating for the domestic hot
water tank.
NOTE
■
In order to provide domestic hot water throughout
the day, it is advised to keep the domestic water
heating operation on continuously.
■
The domestic hot water temperature set point can
only be set manually (refer to "Manual operation"
on page 5).
■
Any domestic water heating operation is
impossible when the domestic hot water tank is
not installed.

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 6).
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 n will appear.
Switching on and setting space cooling (c) and heating (h)
1
Use the = button to select space cooling (c) or space heating
(h).
Icon c or h appears on the display as well as the corresponding
water temperature set point.

NOTE
When the w icon is blinking, hot water is
delivered to the domestic hot water tank by the
solar
kit
option
and
not
by
the
AD indoor unit. Refer to
installation manual of the EKSOLHW solar kit.
Powerful domestic water heating operation
In the case of urgent need of domestic hot water, the domestic hot
water temperature set point can be reached quickly by using the
booster heater. Powerful domestic water heating operation is forcing
the booster heater to operate until the domestic hot water
temperature set point is reached.
This function remains available in solar operation.
Quiet mode operation (s)
Quiet mode operation means that the outdoor unit works at reduced
capacity so that the noise 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.
Operation manual

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 10). 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 10).
Temperature range for cooling: 5°C to 22°C
In heating mode (h), the water temperature set point
can also be weather dependent (icon a is 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.
Switch on the unit by pushing the y button.
The operation LED 0 lights up.
NOTE
When the unit is connected to an external room
thermostat, buttons = and y are not operable and
the icon e is shown. In this case, the external room
thermostat switches the unit on or off and determines
the operation mode (space cooling or space heating).

What can the schedule timer do?
Programming and consulting the schedule timer
The schedule timer allows the programming of:
1.
Space heating and space cooling (refer to "Programming space
cooling or space heating" on page 8)
Switch on the desired mode at a scheduled time, in combination
with a set point (weather dependent or manually set). Five
actions per weekday can be programmed, totalling 35 actions.
When the unit is connected to an external room
thermostat, the schedule timer for space cooling and
space heating is overruled by the external room
thermostat.
NOTE
2.
Quiet mode (refer to "Programming quiet mode, booster heating
or domestic water heating" on page 9)
Switch the mode on or off at a scheduled time. Five actions can
be programmed per mode. These actions are repeated daily.
3.
Booster heating (refer to "Programming quiet mode, booster
heating or domestic water heating" on page 9)
Allow or disallow booster heating at a scheduled time. Five
actions can be programmed per mode. These actions are
repeated daily.
4.
Domestic water heating (refer to "Programming quiet mode,
booster heating or domestic water heating" on page 9)
Switch the mode on or off at a scheduled time. Five actions can
be programmed per mode. These actions are repeated daily.
■
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.
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 9.
NOTE
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.

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 3.
■ 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 cooling/heating program, 5 actions can be
programmed per weekday. The same actions are repeated
on a weekly basis.
- In the domestic water heating, booster heater and quiet
mode program, 5 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.
■ When programming heating actions (time and set point), cooling
actions are added automatically at the same time but with the
predefined default cooling set point. Conversely, when
programming cooling actions (time and setpoint), heating
actions are added automatically at the same time but with the
default heating set point.
The set points of these automatically added actions can be
adjusted by programming the corresponding mode. This means
that after programming heating, you should also program the
corresponding cooling set points and vice versa.
Due to the fact that the schedule timer cannot switch
between operation modes (cooling or heating) and the fact
that each programmed action implies a cooling setpoint
and a heating setpoint, the following situations may occur:
■
when the schedule timer is active in heating mode,
and the mode is changed manually to cooling (by
means of the = button), the operation mode will
from then on remain cooling and program actions will
follow the corresponding cooling setpoints. Returning
to heating mode needs to be carried out manually (by
means of the = button).
■
when the schedule timer is active in cooling mode,
and the mode is changed manually to heating (by
means of the = button), the operation mode will
from then on remain heating and program actions will
follow the corresponding heating setpoints. Returning
to cooling mode needs to be carried out manually (by
means of the = button).
The above proves the importance of programming both
cooling and heating setpoints for each action. If you do not
program these setpoints, the predefined default values will
be used.

Deleting one or more programmed actions
Deleting one or more programmed actions is done at the same time
as storing the programmed actions.
When all actions for one day have been programmed, make sure that
the display shows the highest action number you would like to save.
By pressing the < button for 5 seconds, you store all actions except
those with a higher action number than the one that is displayed.
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 under "Field
settings table" on page 15. In this same list, we provided for 2
columns to register the date and value of altered field settings at
variance with the default value.
A detailed description of each field setting is given under "Detailed
description" on page 11.
Procedure
To change one or more field settings, proceed as follows.

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. See

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.
NOTE
Note that with the function disabled the schedule timer will not be
activated when power returns to the unit after a power supply failure.

turned ON (0) or OFF (1).
[4] Backup heater operation and space heating off temperature
Backup heater operation
The operation of the backup heater can altogether be enabled or
disabled, or it can be disabled depending on operation of the booster
heater.
■ [4-00] Status: defines whether backup heater operation is
enabled (1) or disabled (0).
■ [4-01] Priority: defines whether backup heater and booster
heater can operate simultaneously (0), or if the booster
heater operation has priority over the backup heater
operation (1), or if the backup heater operation has priority
over the booster heater operation (2).
NOTE
When the priority field setting is set to ON (1),
space heating performance of the system
might be decreased at low outdoor
temperatures, since in case of domestic water
heating demand the backup heater will not be
available for space heating (space heating will
still be provided by the heat pump).
When the priority field setting is set to ON (2),
domestic water heating performance of the
system might be decreased at low outdoor
temperatures, since in case of space heating
demand the booster heater will not be
available for domestic water heating. However
domestic water heating by heatpump will still
be available.
[5] Equilibrium

priority
Equilibrium temperature — The 'equilibrium temperature' field
settings apply to operation of the backup heater. When the
equilibrium temperature function is enabled, operation of the backup
heater is restricted to low outdoor temperatures, i.e. when the
outdoor temperature equals or drops below the specified equilibrium
temperature. When the function is disabled, operation of the backup
heater is possible at all outdoor temperatures. Enabling this function
reduces the working time of the backup heater.
■ [5-00] Equilibrium temperature status: specifies whether the
equilibrium temperature function is enabled (1) or
disabled (0).
■ [5-01] Equilibrium temperature: outdoor temperature below
which operation of the backup heater is allowed.
Space heating priority temperature (applies only to installations
with a domestic hot water tank) — The 'space heating priority
temperature' field settings apply to operation of the 3-way valve and
the booster heater in the domestic hot water tank.
When the space heating priority function is enabled, it is assured that
the full capacity of the heat pump is used for space heating only
when the outdoor temperature equals or drops below the specified
space heating priority temperature, i.e. low outdoor temperature. In
this case the domestic water will only be heated by the booster
heater.
■ [5-02] Space heating priority status: specifies whether space
heating priority is enabled (1) or disabled (0).
■ [5-03] Space heating priority temperature: outdoor
temperature below which the domestic water will be heated
by the booster heater only, i.e. low outdoor temperature.
■ [5-04] Set point correction for domestic hot water
temperature: set point correction for the desired domestic hot
water temperature, to be applied at low outdoor temperature
when space heating priority is enabled. The corrected
(higher) set point will make sure that the total heat capacity of
the water in the tank remains approximately unchanged, by
compensating for the colder bottom water layer of the tank
(because the heat exchanger coil is not operational) with a
warmer top layer.

When the priority field setting is set to OFF (0),
make sure that electrical power consumption
does not exceed supply limits.

Applies only to installations with a domestic hot water tank.
The 'DT (delta temperature) for domestic water heating' field settings
determine the temperatures at which heating of the domestic water
by the heat pump will be started (i.e., the heat pump ON
temperature) and stopped (i.e., the heat pump OFF temperature).
When the domestic hot water temperature drops below the heat
pump ON temperature (THP ON), heating of the domestic water by the
heat pump will be started. As soon as the domestic hot water
temperature reaches the heat pump OFF temperature ( THP OFF) or
the user set point temperature (TU), heating of the domestic water by
the heat pump will be stopped (by switching the 3-way valve).

[7] Domestic hot water step length
Applies only to installations with a domestic hot water tank.
When the domestic water is heated and the domestic hot water set
point temperature (as set by the user) has been reached, the booster
heater will continue to heat the domestic water to a temperature a
few degrees above the set point temperature, i.e. the booster heater
OFF temperature. These extra degrees are specified by the domestic
hot water step length field setting. Correct setting prevents the
booster heater from repeatedly turning on and off (i.e. chattering) to
maintain the domestic hot water set point temperature. Note: the
booster heater will turn back on when the domestic hot water
temperature drops 2°C (fixed value) below the booster heater OFF
temperature.
NOTE
If the schedule timer for booster heater (see the
operation manual) is active, the booster heater will only
operate if allowed by this schedule timer.
The 'domestic water heating mode timer' field settings defines the
minimum and maximum domestic water heating times, and minimum
time between two domestic water heating cycli.
■ [8-00] Minimum running time: specifies the minimum time
period during which domestic water heating should be
activated, even when the target domestic hot water
temperature has already been reached.
■ [8-01] Maximum running time: specifies the maximum time
period during which domestic water heating can be activated,
even when the target domestic hot water temperature has
not yet been reached.
Note that when the unit is configured to work with a room
thermostat (refer to the installation manual), the maximum
running timer will only be taken into account when there is a
request for space cooling or space heating. When there is no
request for room cooling or room heating, domestic water
heating by the heat pump will continue until the "heat pump
OFF temperature" (see field settings [5]) is reached. When
no room thermostat is installed, the timer is always taken into
account.
■ [8-02] Anti-recycling time: specifies the minimum required
interval between two domestic water heating cycli.
■ [7-00] Domestic hot water step length: temperature
difference above the domestic hot water set point
temperature before the booster heater is turned off.

By adapting the booster heater delay time versus
the maximum running time, an optional balance
can be found between the energy efficiency and
the heat up time.

[E-00] Readout of the software version (example: 23)
■
[E-01] Readout of the EEPROM version (example: 23)
■
[E-02] Readout of the unit model identification (example: 11)
However, if the booster heater delay time is set
too high, it might take a long time before the
domestic hot water reaches its set temperature
upon domestic water heating mode request.
■
[E-03] Readout of the liquid refrigerant temperature
■
[E-04] Readout of the inlet water temperature
■
When the default value is not changed, the unit will run in
restricted power supply condition mode. Refer to the
manual for restricted power supply condition and take note
of the limitations.

[E-03] and [E-04] readouts are not permanently
refreshed. Temperature readouts are updated
after looping through the field setting first codes
again only.
[9] Cooling and heating set points
The purpose of this field setting is to prevent the user from selecting
a wrong (i.e., too hot or too cold) leaving water temperature. Thereto
the heating temperature set point range and the cooling temperature
set point range available to the user can be configured.
■
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 to 16°C to prevent condensation on
the floor.
■ [9-00] Heating set point upper limit: maximum leaving
temperature for heating operation.
■ [9-01] Heating set point lower limit: minimum leaving
temperature for heating operation.
■ [9-02] Cooling set point upper limit: maximum leaving
temperature for cooling operation.
■ [9-03] Cooling set point lower limit: minimum leaving
temperature for cooling operation.

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.
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.
Besides keeping the remote controller clean by means of a soft damp
cloth, no maintenance is required by the operator.
Standstill
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 motor in order to prevent it from
getting jammed.
TROUBLESHOOTING
The guidelines below might help to solve your problem. If you cannot
solve the problem, consult your installer.
■
No readings on the remote controller (blank display)
Check if the mains power is still connected to your installation.
■
One of the error codes appears
Consult your local dealer.
■
The schedule timer does work but the programmed actions are
executed at the wrong time (e.g. 1 hour too late or too early)
Check if the clock and the day of the week are set correctly,
correct if necessary.
