3. INTRODUCTION
3.1. General information
Thank you for purchasing this product.
This unit is used for both heating and cooling applications. The unit
can be combined with Daikin fan coil units, floor heating applications,
low temperature radiators, domestic hot water tank (option) and
Daikin solar kit (option).
A remote controller is standard supplied with the unit to control your
installation.
Heating/cooling units and heating only units
The unit range consists of two main versions: a heating/cooling (EB)
version and a heating only (ED) version.
Nordic units
EDL and EBL units include special equipment (insulation, heater
sheet,...) to ensure good operation in areas where low ambient
temperature can occur together with high humidity conditions. In
such conditions the EDH and EBH models may experience problems
with severe ice build up on the air-cooled coil. In case such
conditions are expected, the EDL or EBL must be installed instead.
These models contain countermeasures (insulation, heater sheet,...)
to prevent freeze up.
■ Possible options
Heater sheet Drain socket
EDLQ, EBLQ Standard Use prohibited
EDHQ, EBHQ Optional kit
(a) Combination of both options is prohibited.
The units 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 unit and for freeze protection of the outside water piping during
winter time. The backup heater factory set capacity is 6 kW, however,
depending on the installation, the installer can limit the backup heater
capacity to 3 kW/2 kW. The backup heater capacity decision is a
mode based on the equilibrium temperature, see scheme below.

Application 5
Space heating with an auxiliary boiler (alternating operation)
Space heating application by either the Daikin unit or by an auxiliary
boiler connected in the system. The decision whether either the
E(D/B)* unit or the boiler will operate can be achieved by an auxiliary
contact or an E(D/B)* 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 E(D/B)* unit controlled contact (also called 'permission signal for
the auxiliary boiler") is determined by the outdoor temperature
(thermistor located at the 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 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.
■ Always install a 3-way valve, even if no domestic hot
water tank is installed. This to ensure that the freeze
protection function (see "Freeze protection function"
on page 35) can operate when the boiler is active.

Operation
■ Configuration A
When the room thermostat requests heating, either the E(D/B)*
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 E(D/B)*
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 E(D/B)* 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 E(D/B)* 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 E(D/B)* unit and the boiler. As the
outdoor temperature is measured via the unit’s air
thermistor, make sure to install the 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 E(D/B)* 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 unit.
NOTICE
Make sure to configure the DIP switch SS2-3 on the PCB
of the E(D/B)* switch box correctly. Refer to "10.2. Room
thermostat installation configuration" on page 29.
For configuration B: Make sure to configure the field
settings [C-02, C-03 and C-04] correctly. Refer to "Bivalent
operation" on page 41.
NOTICE
Make sure that return water to the E(D/B)* 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 E(D/B)* 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 E(D/B)* unit again.
INFORMATION
Manual permission towards the E(D/B)* unit on the boiler.
In case only the E(D/B)* 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.

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 achieve 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.

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. (unit - 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 39 for more details.

■ Carry out the specified installation work in
consideration of strong winds, typhoons, or
earthquakes.
Improper installation work may result in accidents due
to fall of equipment.
■ The equipment is not intended for use in a potentially
explosive atmosphere.
■ Be sure that sufficient precautions are taken, in
accordance with the applicable legislation, in case of
refrigerant leakage.
CAUTION
Do not install the unit in places such as the following:
■ Where there is mist of mineral oil, oil spray or vapour.
Plastic parts may deteriorate, and cause them to fall
out or water to leak.
■ Where corrosive gas, such as sulphurous acid gas, is
produced.
Corrosion of copper pipes or soldered parts may
cause the refrigerant to leak.
■ Where there is machinery which emits
electromagnetic waves.
Electromagnetic waves may disturb the control
system, and cause malfunction of the equipment.
■ Where flammable gases may leak, where carbon fibre
or ignitable dust is suspended in the air or where
volatile flammables, such as thinner or gasoline, are
handled.
Such gases may cause a fire.

General
1 Select an installation site where the following conditions are
satisfied and that meets with your customer's approval.
- Places which are well-ventilated.
- Places where the unit does not bother next-door neighbours.
- Safe places which can withstand the unit's weight and
vibration and where the unit can be installed level.
- Places where servicing space can be well ensured.
- Places where the units' piping and wiring lengths come within
the allowable ranges.
- Places where water leaking from the unit cannot cause
damage to the location (e.g. in case of a blocked drain pipe).
- Places where the rain can be avoided as much as possible.
- Do not install the unit in places often used as workplace.
In case of construction works (e.g. grinding works) where a
lot of dust is created, the unit must be covered.
- Do not place any objects or equipment on top of the unit (top
plate)
- Do not climb, sit or stand on top of the unit.
- All piping lengths and distances have been taken into
consideration.
Requirement Value
Maximum allowable distance between the domestic
hot water tank and the unit (only for installations with
domestic hot water tank). The thermistor cable
supplied with the domestic hot water tank is 12 m in
length.
In order to optimise efficiency Daikin recommends to
install the 3-way valve and the domestic hot water
tank as close as possible to the unit.
2 When installing the unit in a place exposed to strong wind, pay
special attention to the following.
Strong winds of 5 m/sec or more blowing against the unit's air
outlet causes short circuit (suction of discharge air), and this
may have the following consequences:
- deterioration of the operational capacity,
- frequent frost acceleration in heating operation,
- disruption of operation due to rise of high pressure,
- when a strong wind blows continuously on the face of the
unit, the fan can start rotating very fast until it breaks.
Refer to the figures for installation of this unit in a place where
the wind direction can be foreseen.
■ Tu rn the air outlet side toward the building's wall, fence or
screen.
10 m
3 Prepare a water drainage channel around the foundation, to
drain waste water from around the unit.
4 If the water drainage of the unit is not easy, please build up the
unit on a foundation of concrete blocks, etc. (the height of the
foundation should be maximum 150 mm).
5 If you install the unit on a frame, please install a waterproof plate
within 150 mm of the underside of the unit in order to prevent the
invasion of water from the lower direction.
6 When installing the unit in a place frequently exposed to snow,
pay special attention to elevate the foundation as high as
possible.
7 If you install the unit on a building frame,
please install a waterproof plate (field
supply) (within 150 mm of the underside of
the unit) in order to avoid the drainwater
dripping. (See figure).
Selecting a location in cold climates
NOTICE
When operating the unit in a low outdoor ambient
temperature, be sure to follow the instructions described
below.
■ To prevent exposure to wind, install the unit with its suction side
facing the wall.
■ Never install the unit at a site where the suction side may be
exposed directly to wind.
■ To prevent exposure to wind, install a baffle plate on the air
discharge side of the unit.
■ In heavy snowfall areas it is very important to select an
installation site where the snow will not affect the unit and to set
the outlet side at a right angle to the direction of the wind:
1
Make sure there is enough room to do the installation
■ Set the outlet side at a right angle to the direction of the wind.
