INTRODUCTION

General information

Thank you for purchasing this 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

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.

An EKHBRD indoor unit can only be connected to an
ERSQ or ERRQ outdoor unit.

PCB installation manual for more information.

Refer to the wiring diagram or connection diagram for connecting this
PCB to the unit.

Demand PCB (option)

An optional EKRP1AHTA demand PCB can be connected to the
indoor unit. This PCB is needed when the optional heater kit EKBUH
or Daikin room thermostat EKRTR or EKRTW is installed or when
multiple set point control is used, and provides the communication
with the indoor unit.

Refer to the demand PCB installation manual for further details.
Refer to the wiring diagram or connection diagram for connecting this

PCB to the unit.

B Living room

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.

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). The main remote
controller (C1) is installed in the living room and can access all
settings (master). The second remote controller (C2) can not access
schedule and parameter settings (slave).

Application 4

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.

Pattern A

The domestic hot water tank is installed in parallel with the mixing
station(s). This allows operating the unit in space heating and
domestic water heating simultaneously. The balancing of the water
distribution is in this case the responsibility of the installer.

Pattern B

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.

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. 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.

Operation

When the room thermostat (th) closes, either the EKHBRD* unit or
the boiler starts operating, depending on the position of the auxiliary
contact (C).

NOTE

■ Make sure that auxiliary contact (C) has sufficient
differential or time delay so as to avoid frequent
changeover between the EKHBRD* unit and the
boiler. If the auxiliary contact (C) 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.

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

■ 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.

Water piping work

Checking the water volume and expansion vessel
pre-pressure

The unit is equipped with an expansion vessel of 12 litre which has a
default pre-pressure of 1 bar.

To assure proper operation of the unit, the pre-pressure of the
expansion vessel might need to be adjusted and the minimum and
maximum water volume must be checked.

1 Check that the total water volume in the installation, excluding

the internal water volume of the unit, is 20 l minimum.

In most applications this minimum water volume will have a
satisfying result.

In critical processes or in rooms with a high heat load
though, extra water volume might be required.

When circulation in each space heating/radiator loop is
controlled by remotely controlled valves, it is important that
this minimum water volume is kept even if all the valves are
closed.

Checking the water circuit

The units are equipped with a water inlet and water outlet for
connection to a water circuit. This circuit must be provided by a
licensed technician and must comply with all relevant European and
national regulations.

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.

Before continuing the installation of the unit, check the following
points:

■ The maximum water pressure is 4 bar.

■ The maximum water temperature is 85°C.

■ Drain taps must be provided at all low points of the system to

permit complete drainage of the circuit during maintenance.
One drain valve in the indoor unit, and a drain valve on the

expansion vessel are provided to drain the water from the indoor
unit water system.

■ Make sure to provide a proper drain for the pressure relief valve
to avoid any water coming into contact with electrical parts.

■ Air vents must be provided at all high points of the system. The
vents should be located at points which are easily accessible for
servicing. An automatic air purge is provided inside the indoor
unit. Check that this air purge valve is not tightened too much so
that automatic release of air in the water circuit remains possible.

■ Ta ke care that the components installed in the field piping can
withstand the water pressure and temperature.

■ Always use materials which are compatible with the water used
in the system and with the materials used on the indoor unit.
