Be sure to wear adequate personal protection equipment (protection
gloves, safety glasses, …) when performing installation, maintenance
or service to the unit.

If not sure of installation procedures or operation of the unit, always
contact your local dealer for advice and information.

Improper installation or attachment of equipment or accessories
could result in electric shock, short-circuit, leaks, fire or other damage
to the equipment. Be sure only to use accessories and optional
equipment made by Daikin which are specially designed for use with
the products as of subject in this manual and have them installed by
an installer.

DANGER: ELECTRICAL SHOCK

Switch off all power supply before removing the switch box
service panel or before making any connections or
touching electrical parts.

Do not touch any switch with wet fingers. Touching a switch
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
PA RT S

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

■ Tear apart and throw away plastic packaging bags so
that children will not play with them.
Children playing with plastic bags face danger of death
by suffocation.

■ Safely dispose of packing materials. Packing materials,
such as nails and other metal or wooden parts, may
cause stabs or other injuries.

EKCBX/H008BBV3

4PW66983-1C – 08.2011

■ Ask your dealer or qualified personnel to carry out
installation work.
Do not install the machine by yourself.
Improper installation may result in water leakage, electric
shocks or fire.

■ Perform installation work in accordance with this
installation manual.
Improper installation may lead to water leakage, electric
shocks or fire.

■ Be sure to use only the specified accessories and parts
for installation work.
Failure to use the specified parts may result in water
leakage, electric shocks, fire, or the unit falling.

■ Install the unit on a foundation that can withstand its
weight.

■ Insufficient strength may result in the fall of equipment
and causing injury.

■ Carry out the specified installation work in consideration
of strong winds, hurricanes, or earthquakes.
Improper installation work may result in accidents due to
fall of equipment.

■ Make certain that all electrical work is carried out by
qualified personnel according to the applicable legislation
and this installation manual, using a separate circuit.
Insufficient capacity of the power supply circuit or
improper electrical construction may lead to electric
shocks or fire.

■ Be sure to install an earth leakage circuit breaker in
accordance with the applicable legislation. Failure to do
so may cause electrical shock and fire.

■ Make sure that all wiring is secure, using the specified
wires and ensuring that external forces do not act on the
terminal connections or wires.
Incomplete connection or fixing may cause a fire.

■ When wiring between the indoor and the outdoor units
and wiring the power supply, form the wires so that the
panels can be securely fastened.
If the panels are not in place, overheat of the terminals,
electric shocks or a fire may be caused.

■ After completing the installation work, check to make
sure that there is no leakage of refrigerant gas.

■ Never directly touch any accidental leaking refrigerant.
This could result in severe wounds caused by frostbite.

■ Electrical work must be carried out in accordance with
the installation manual and the national electrical wiring
rules or code of practice.
Insufficient capacity or incomplete electrical work may
cause electrical shock or fire.

■ Be sure to use a dedicated power circuit. Never use a
power circuit shared by another appliance.

■ For wiring, use a cable long enough to cover the entire
distance with no connection. Do not use an extension
cord. Do not put other loads on the power supply, use a
dedicated power circuit.
Failure to do so may cause abnormal heat, electric
shock, or fire.

■ 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

■ For use of units in applications with temperature
alarm settings it is advised to foresee a delay of 10
minutes for signalling the alarm in case the alarm
temperature is exceeded. The unit may stop for
several minutes during normal operation for
"defrosting of the unit" or when in "thermostat-stop"
operation.

■ Earth the unit.
Earth resistance should be according to the applicable
legislation.
Do not connect the earth wire to gas or water pipes,
lightning conductor or telephone earth wire.
Incomplete earthing may cause electric shocks.

- Gas pipe.

Ignition or explosion may occur if the gas leaks.

-Water pipe.

Hard vinyl tubes are not effective earths.

- Lightning conductor or telephone earth wire.

Electric potential may rise abnormally if struck by a
lightning bolt.

■ Install the indoor and outdoor units, power wire and
connecting wire at least 1 meter away from televisions or
radios to prevent image interference or noise.
(Depending on the radio waves, a distance of 1 meter
may not be sufficient to eliminate the noise.)

3. INTRODUCTION

3.1. General information

This installation manual concerns the indoor unit EKCBX008BBV3
and EKCBH008BBV3 of the Monoblock units of the GBS Altherma
series.

The Monoblock units exist out of an outdoor installed unit (EBHQ)
and an indoor installed (wall mounted) unit (EKCB (this manual)).

These units are used for both heating and cooling applications. The
units can be combined with Daikin fan coil units, floor heating
applications, low temperature radiators, domestic hot water tank
(option) and solar kit (option).

A user interface is standard supplied with the unit to control your
installation.

Heating/cooling units and heating only units

The monoblock unit range consists of two main versions: a
heating/cooling version (uses EKCBX indoor unit) and a heating only
version (uses EKCBH indoor unit), both available in 2 capacity sizes:
6 kW (EBHQ006) or 8 kW (EBHQ008).

3.2. Combination and options

Possible combinations

Domestic water heating

When domestic water heating mode is enabled (either manually by
the user, or automatically through a schedule timer) the target
domestic hot water temperature will be achieved by a combination of
the heat exchanger coil and the electrical booster heater.

When the domestic hot water temperature is below the user
configured set point, the 3-way valve will be activated to heat the
domestic water by means of the heat pump. In case of large domestic
hot water demand or a high domestic hot water temperature setting,
the booster heater (9) can provide auxiliary heating.

CAUTION

It is possible to connect either a 2-wire or a 3-wire 3-way
valve (7). Make sure to fit the 3-way valve correctly. For
more details, refer to "Wiring the 3-way valve" on page 19.

INFORMATION

The unit can be configured so that at low outdoor
temperatures the domestic water is exclusively heated by
the booster heater. This assures that the full capacity of the
heat pump is available for space heating.

8.5. Application 5

Space heating with an auxiliary boiler (alternating operation)

8

Space heating application by either the Daikin unit or by an auxiliary
boiler connected in the system. The decision whether either the
EBHQ* unit or the boiler will operate can be achieved by an auxiliary
contact or an EKCB* indoor controlled contact.

The auxiliary contact can e.g. be an outdoor temperature thermostat,
an electricity tariff contact, a manually operated contact, etc. See

"Field wiring configuration A" on page 10.

The EKCB* unit controlled contact (also called "permission signal for
the auxiliary boiler") is determined by the outdoor temperature
(thermistor located at the outdoor unit). See "Field wiring

configuration B" on page 10.

Bivalent operation is only possible for space heating operation, not
for the domestic 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 unit.

The auxiliary boiler must be integrated in the piping work and in the
field wiring according to the illustrations below.

Installation manual

CAUTION

■ Be sure that the boiler and the integration of the boiler
in the system is in accordance with the applicable
legislation.

■ Always install a 3-way valve, even if no domestic hot
water tank is installed. This to ensure that the freeze
protection function (see "[4-04] Freeze protection

NOTICE

■ Configuration A

Make sure that auxiliary contact (A) has sufficient
differential or time delay so as to avoid frequent
changeover between the EBHQ* unit and the boiler. If
the auxiliary contact (A) is an outdoor temperature
thermostat, make sure to install the thermostat in the
shade, so that it is not influenced or turned ON/OFF
by the sun.

Configuration B

Make sure that the bivalent hysteresis [C-04] has
sufficient differential to avoid frequent changeover
between the EBHQ* unit and the boiler. As the outdoor
temperature is measured via the outdoor unit’s air
thermistor, make sure to install the outdoor unit in the
shade, so that it is not influenced by the sun.

Frequent switching may cause corrosion of the boiler
in an early stage. Contact the manufacturer of the
boiler.

■ During heating operation of the EBHQ* 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 55°C.

■ Make sure to only have 1 expansion vessel in the
water circuit. An expansion vessel is already
premounted in the unit.

8.6. Application 6

Space heating with room thermostat application through floor heating
loops and fan coil units. The floor heating loops and fan coil units
require different operating water temperatures.

The floor heating loops require a lower water temperature in heating
mode compared to fan coil units. To achive these two set points, a
mixing station is used to adapt the water temperature according to
requirements of the floor heating loops. The fan coil units are directly
connected to the unit water circuit and the floor heating loops after
the mixing station. The control of this mixing station is not done by the
unit.

The operation and configuration of the field water circuit is the
responsibility of the installer.

Daikin only offers a dual set point control function. By this function
two set points can be generated. Depending on the required water
temperature (floor heating loops and/or fan coil units are required)
first set point or second set point can be activated.

(a) The aquastat valve must be set for 55°C and must operate to close the return

water flow to the unit when the measured temperature exceeds 55°C. When the
temperature drops to a lower level, the aquastat valve must operate to open the
return water flow to the EBHQ* unit again.

INFORMATION

■ The advantage of the dual set point control is that the
heat pump will/can operate at the lowest required
leaving water temperature when only floor heating is
required. Higher leaving water temperatures are only
required in case fan coil units are operating.
This results in a better performance of the heat pump.

■ The hydraulic balance is very important. (outdoor unit

- heater kit (if applicable) - mixing station - FCU1...3)

INFORMATION

Manual permission towards the EBHQ* unit on the boiler.
In case only the EBHQ* unit should operate in space

heating mode, disable the bivalent operation via setting
[C-02].

In case only the boiler should operate in space heating
mode, increase the bivalent ON temperature [C-03] to
25°C.

Pump operation and space heating

When the room thermostat for the floor heating loop (T1) and the fan
coil units (T2) are connected to the indoor unit, the pump (3) will
operate when there is a request for heating from T1 and/or T2. The
outdoor unit will start operating to achieve the target leaving water
temperature. The target leaving water temperature depends on which
room thermostat is requesting heating.

Set point Field setting Thermo status

Zone A First UI ON OFF ON OFF
Zone B Second [7-03] OFF ON ON OFF
Resulting water temperature UI [7-03] [7-03] —
Result pump operation ON ON ON OFF

When the room temperature of both zones is above the thermostat
set point, the outdoor unit and pump will stop operating.

NOTICE

■ Make sure to connect the thermostat wires to the
correct terminals (see "5. Overview of unit" on

page 5).

■ Make sure to configure the field settings [7-02], [7-03]
and [7-04] correctly. Refer to "Dual set point control"

on page 29.

■ Make sure to configure the DIP switch SS2-3 on the
PCB of the EBHQ* switch box correctly. Refer to

"12.2. Room thermostat installation configuration" on
page 21.

9. INSPECTING, HANDLING AND UNPACKING

THE UNIT

9.1. Inspection

At delivery, the unit must be checked and any damage must be
reported immediately to the carrier’s claims agent.

9.2. Handling

■ The unit is packed in a cardboard box.

■ When handling the unit, take into account the following:

Fragile, handle the unit with care

Keep the unit upright

9.3. Unpacking

WARNING

Tear apart and throw away plastic packaging bags so that
children will not play with them. Children playing with
plastic bags face danger of death by suffocation.

Make sure that all accessories as mentioned in "4.2. Accessories

supplied with the indoor unit" on page 5 are available in the unit.

NOTICE

■ The request signals for space heating can be
implemented in two different ways (installer choice).

- Thermo ON/OFF signal from room thermostat

- Status signal (active/not active) from the mixing

station

■ It is the installers responsibility to make sure no
unwanted situations can occur (e.g. too high water
temperatures towards floor heating loops, etc.)

■ Daikin does not offer any type of mixing station. Dual
set point control only provides the possibility to use
two set points.

■ When only zone A requests heating, zone B will be
fed with water at a temperature equal to the first set
point.
This can lead to unwanted heating of zone B.

■ When only zone B requests heating, the mixing
station will be fed with water at a temperature equal to
the second set point.
Depending on the control of the mixing station, the
floor heating loop can still receive water at a
temperature equal to set point of the mixing station.

■ Be aware that the actual water temperature through
the floor heating loops depends on the control and
setting of the mixing station.

9.4. Installing the unit

When installing the indoor unit, please refer to "6. Selecting an

installation location" on page 6 to select an appropriate location.
