3. INTRODUCTION
3.1. General information
Thank you for purchasing this indoor unit.
The unit is the indoor part of the air to water ERHQ or ERLQ heat
pumps. This unit is designed for wall mounted indoor installation. See
"6.1. Selecting an installation location" on page 12. The unit can be
combined with Daikin fan coil units, floor heating applications, low
temperature radiators, Daikin domestic water heating applications
and Daikin solar kit for domestic hot water applications.
Heating/cooling units and heating only units
The 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 low 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 3, 6 and 9 kW, and – depending on the heating
capacity – for three different power supply specifications.

Application 5
Space heating with an auxiliary boiler (alternating operation)
Space heating application by either the Daikin indoor unit or by an
auxiliary boiler connected in the system. The decision whether either
the EKHB* indoor unit or the boiler will operate can be achieved by
an auxiliary contact or an EKHB* 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 7.
The EKHB* indoor 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 8.
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 indoor unit.
The auxiliary boiler must be integrated in the piping work and in the
field wiring according to the illustrations below.
CAUTION
■ Be sure that the boiler and the integration of the boiler
in the system is in accordance with the applicable
legislation.
■ Daikin can not be put responsible for incorrect or

Operation
■ Configuration A
When the room thermostat requests heating, either the EKHB*
unit or the boiler starts operating, depending on the position of
the auxiliary contact (A).
■ Configuration B
When the room thermostat requests heating, either the EKHB*
unit or the boiler starts operating, depending on the outdoor
temperature (status of "permission signal for the auxiliary
boiler").
When the permission is given towards the boiler, the space
heating operation by the EKHB* unit will be automatically
switched off.
For more details see field setting [C-02~C-04].
NOTICE
■ Configuration A
Make sure that auxiliary contact (A) has sufficient
differential or time delay so as to avoid frequent
changeover between the EKHB* 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 EKHB* unit and the boiler. As the
outdoor temperature is measured via the outdoor unit,
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 EKHB* 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 Daikin indoor unit.
NOTICE
Make sure that return water to the EKHB* heat exchanger
never exceeds 55°C.
For this reason, never put the target leaving water
temperature set point on the boiler controller above 55°C
and install an aquastat
(a)
valve in the return water flow of
the EKHB* unit.
Make sure that the non-return valves (field supply) are
correctly installed in the system.
Make sure that the room thermostat EKRTR or EKRTW
are 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 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 EKHB* unit again.
INFORMATION
Manual permission towards the EKHB* unit on the boiler.
In case only the EKHB* 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.
Domestic water heating
Domestic water heating is as described under "Application 2" on
page 5.
NOTICE
Make sure to configure the DIP switch SS2-3 on the PCB
of the EKHB* switch box correctly. Refer to "8.2. Room

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 indoor unit water circuit and the floor heating loops
after the mixing station. The control of this mixing station is not done
by the indoor 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.

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 the indoor unit"
on page 10).
■ Make sure to configure the field settings [7-02], [7-03]
and [7-04] correctly. Refer to "Dual set point control"
on page 33.
■ Make sure to configure the DIP switch SS2-3 on the
PCB of the EKHBH switch box correctly. Refer to
"8.2. Room thermostat installation configuration" on
page 23.
■ It is the installers responsibility to make sure no
unwanted situations can occur (e.g. too high water
temperatures towards floor heating loops, etc.)
■ Be aware that the actual water temperature through
the floor heating loops depends on the control and
setting of the mixing station.

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. (Hydrobox mixing station - FCU1...3)
INFORMATION
■ 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
■ 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 request 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 request 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.
■ At this type of application heating/cooling selection
always has to be done on the user interface. Refer to
"Dual set point control" on page 33 for more details.
