DANGER: RISK OF EXPLOSION
Pump down – Refrigerant leakage. If you want to pump
down the system, and there is a leak in the refrigerant
circuit:
▪ Do NOT use the unit's automatic pump down function,
with which you can collect all refrigerant from the
system into the outdoor unit. Possible consequence:
Self-combustion and explosion of the compressor
because of air going into the operating compressor.
▪ Use a separate recovery system so that the unit's
compressor does NOT have to operate.
WARNING
ALWAYS recover the refrigerant. Do NOT release them
directly into the environment. Use a vacuum pump to
evacuate the installation.
NOTICE
After all the piping has been connected, make sure there is
no gas leak. Use nitrogen to perform a gas leak detection.
NOTICE
▪ To avoid compressor breakdown, do NOT charge more
than the specified amount of refrigerant.
▪ When the refrigerant system is to be opened,
refrigerant MUST be treated according to the applicable
legislation.
WARNING
Make sure there is no oxygen in the system. Refrigerant
may only be charged after performing the leak test and the
vacuum drying.
▪ In case re-charge is required, refer to the nameplate of the unit. It
states the type of refrigerant and necessary amount.
▪ The unit is factory charged with refrigerant and depending on pipe
sizes and pipe lengths some systems require additional charging
of refrigerant.
▪ Only use tools exclusively for the refrigerant type used in the
system, this to ensure pressure resistance and prevent foreign
materials from entering into the system.
▪ Charge the liquid refrigerant as follows:
If Then
A siphon tube is present
(i.e., the cylinder is marked with
"Liquid filling siphon attached")
Charge with the cylinder upright.
A siphon tube is NOT present Charge with the cylinder upside
down.
▪ Open refrigerant cylinders slowly.
▪ Charge the refrigerant in liquid form. Adding it in gas form may
prevent normal operation.
CAUTION
When the refrigerant charging procedure is done or when
pausing, close the valve of the refrigerant tank
immediately. If the valve is NOT closed immediately,
remaining pressure might charge additional refrigerant.
Possible consequence: Incorrect refrigerant amount.
1.2.4 Brine
If applicable. See the installation manual or installer reference guide
of your application for more information.
WARNING
The selection of the brine MUST be in accordance with the
applicable legislation.
WARNING

of the earth leakage protector.
NOTICE
Precautions when laying power wiring:
▪ Do NOT connect wiring of different thicknesses to the
power terminal block (slack in the power wiring may
cause abnormal heat).
▪ When connecting wiring which is the same thickness,
do as shown in the figure above.
▪ For wiring, use the designated power wire and connect
firmly, then secure to prevent outside pressure being
exerted on the terminal board.
▪ Use an appropriate screwdriver for tightening the
terminal screws. A screwdriver with a small head will
damage the head and make proper tightening
impossible.
▪ Over-tightening the terminal screws may break them.
Install power cables at least 1metre away from televisions or radios
to prevent interference. Depending on the radio waves, a distance of
1metre may not be sufficient.
WARNING
▪ After finishing the electrical work, confirm that each
electrical component and terminal inside the electrical
components box is connected securely.
▪ Make sure all covers are closed before starting up the
unit.
NOTICE
Only applicable if the power supply is three‑phase, and the
compressor has an ON/OFF starting method.
If there exists the possibility of reversed phase after a
momentary black out and the power goes on and off while
the product is operating, attach a reversed phase
protection circuit locally. Running the product in reversed
phase can break the compressor and other parts.

5.2 Setting up the space heating/
cooling system
The heatpump system supplies leaving water to heat emitters in one
or more rooms.
Because the system offers a wide flexibility to control the
temperature in each room, you need to answer the following
questions first:
▪ How many rooms are heated or cooled by the Daikin heatpump
system?
▪ Which heat emitter types are used in each room and what is their
design leaving water temperature?
Once the space heating/cooling requirements are clear, Daikin
recommends to follow the setup guidelines below.

5.2.2 Multiple rooms – OneLWT zone
If only one leaving water temperature zone is needed because the
design leaving water temperature of all heat emitters is the same,
you do NOT need a mixing valve station (cost effective).
Example: If the heat pump system is used to heat up one floor
where all the rooms have the same heat emitters.
Underfloor heating or radiators – Thermostatic
valves
If you are heating up rooms with underfloor heating or radiators, a
very common way is to control the temperature of the main room by
using a thermostat (this can either be the user interface connected to
control box EKCB07CAV3, or an external room thermostat), while
the other rooms are controlled by so-called thermostatic valves (field
supply), which open or close depending on the room temperature.

▪ For each room, a shut-off valve (field supplied) is installed to avoid
leaving water supply when there is no heating or cooling demand.
▪ A bypass valve must be installed to make water recirculation
possible when all shut-off valves are closed. To guarantee reliable
operation, provide a minimum water flow as described in table "To
check the water volume and flow rate" in "6.3 Preparing water
piping"on page23.
▪ The main user interface (connected to control box EKCB07CAV3)
decides the space operation mode. Mind that the space operation
mode of the additional user interfaces (used as room thermostat)
must be set to match that of the main user interface.
▪ The room thermostats are connected to the shut-off valves, and
do NOT have to be connected to the outdoor unit. The outdoor

▪ For each room with heat pump convectors: The heat pump
convectors are directly connected to the outdoor unit.
▪ For each room with underfloor heating: Two shut-off valves (field
supply) are installed before the underfloor heating:
▪ A shut-off valve to prevent hot water supply when the room has
no heating demand
▪ A shut-off valve to prevent condensation on the floor during
cooling operation of the rooms with heatpump convectors.
▪ For each room with heat pump convectors: The desired room
temperature is set via the remote controller of the heat pump
convectors.
▪ For each room with under floor heating: The desired room
temperature is set via the external room thermostat (wired or
wireless).
▪ The main user interface (connected to control box EKCB07CAV3)
decides the space operation mode. Mind that the operation mode
of each external room thermostat and heat pump convector
remote controller must be set to match that of the main user
interface.
INFORMATION
To increase comfort and performance, Daikin recommends
to install the valve kit option EKVKHPC on each heatpump
convector.

5.2.3 Multiple rooms – TwoLWT zones
If the heat emitters selected for each room are designed for different
leaving water temperatures, you can use different leaving water
temperature zones (maximum 2).
In this document:
▪ Main zone = Zone with the lowest design temperature in heating,
and the highest design temperature in cooling
▪ Additional zone = Zone with the highest design temperature in
heating, and the lowest design temperature in cooling.
NOTICE
If there are two leaving water temperature zones, and an
external room thermostat is used, then cooling operation is
NOT possible.
CAUTION
When there is more than one leaving water zone, you must
ALWAYS install a mixing valve station in the main zone to
decrease (in heating)/increase (in cooling) the leaving
water temperature when the additional zone has demand.
Typical example:
Room (zone) Heat emitters: Design
temperature
Living room (main zone) Underfloor heating: 35°C
Bed rooms (additional zone) Heatpump convectors: 45°C

INFORMATION
A pressure regulating valve should be implemented before
the mixing valve station. This is to guarantee the correct
water flow balance between the main leaving water
temperature zone and the additional leaving water
temperature zone in relation to the required capacity of
both water temperature zones.
▪ For the main zone:
▪ A mixing valve station is installed before the underfloor heating.
▪ The room temperature is controlled by the user interface, which
is used as room thermostat.
NOTICE
Daikin is NOT responsible for the operation of the mixing
valve station pump. It is the responsibility of the installer to
guarantee pump operation.
▪ For the additional zone:
▪ The heat pump convectors are directly connected to the
outdoor unit.
▪ The desired room temperature is set via the remote controller of
the heatpump convectors for each room.
▪ The heating or cooling demand signals of each heat pump
convector are connected in parallel to the digital input on control
box EKCB07CAV3 (X2M/1 and X2M/2). The outdoor unit will
only supply the desired additional leaving water temperature
when there is an actual demand.
▪ The main user interface (connected to control box EKCB07CAV3)
decides the space operation mode. Mind that the operation mode
of each heat pump convector remote controller must be set to
match that of the main user interface.

5.3.2 Selecting the volume and desired
temperature for the DHW tank
People experience water as hot when its temperature is 40°C.
Therefore, the DHW consumption is always expressed as equivalent
hot water volume at 40°C. However, you can set the DHW tank
temperature at a higher temperature (example: 53°C), which is then
mixed with cold water (example: 15°C).
Selecting the volume and desired temperature for the DHW tank
consists of:
1 Determining the DHW consumption (equivalent hot water
volume at 40°C).
2 Determining the volume and desired temperature for the DHW
tank.
Determining the DHW consumption
Answer the following questions and calculate the DHW consumption
(equivalent hot water volume at 40°C) using typical water volumes:
Question Typical water volume
How many showers are needed
per day?
1shower = 10min×10l/min =
100l
How many baths are needed per
day?
1bath = 150l
How much water is needed at the
kitchen sink per day?
1sink = 2min×5l/min = 10l
Are there any other domestic hot
water needs?
—
Example: If the DHW consumption of a family (4 persons) per day
is as follows:
▪ 3 showers
▪ 1 bath
▪ 3 sink volumes
Then the DHW consumption = (3×100l)+(1×150l)+(3×10l)=480l
Determining the volume and desired temperature for the DHW
tank
Formula Example
V1=V2+V2×(T2−40)/(40−T1) If:
▪ V2=180l
▪ T2=54°C
▪ T1=15°C
Then V1=280l
V2=V1×(40−T1)/(T2−T1) If:
▪ V1=480l
▪ T2=54°C
▪ T1=15°C
Then V2=307l
V1DHW consumption (equivalent hot water volume at 40°C)
V2Required DHW tank volume if only heated once
T2DHW tank temperature
T1Cold water temperature
Possible DHW tank volumes
Type Possible volumes
Standalone DHW tank ▪ 150l
▪ 180l
▪ 200l
▪ 250l
▪ 300l
▪ 500l
Energy saving tips
▪ If the DHW consumption differs from day to day, you can program
a weekly schedule with different desired DHW tank temperatures
for each day.
▪ The lower the desired DHW tank temperature, the more cost
effective. By selecting a larger DHW tank, you can lower the
desired DHW tank temperature.
▪ The heatpump itself can produce domestic hot water of maximum
55°C (50°C if outdoor temperature is low). The electrical
resistance integrated in the heat pump can increase this
temperature. However, this consumes more energy. Daikin
recommends to set the desired DHW tank temperature below
55°C to avoid using the electrical resistance.
▪ The higher the outdoor temperature, the better the performance of
the heatpump.
▪ If energy prices are the same during the day and the night,
Daikin recommends to heat up the DHW tank during the day.
▪ If energy prices are lower during the night, Daikin recommends
to heat up the DHW tank during the night.
▪ When the heatpump produces domestic hot water, it cannot heat
up a space. In case you need domestic hot water and space
heating at the same, Daikin recommends to produce the domestic
hot water during the night when there is lower space heating
demand.

5.4.1 Produced heat
INFORMATION
The sensors used to calculate the produced heat are
calibrated automatically.
INFORMATION
If glycol is present in the system ([E‑0D]=1]), then the
produced heat will NOT be calculated, nor will it be
displayed on the user interface.
▪ Applicable for all models.
▪ The produced heat is calculated internally based on:
▪ The leaving and entering water temperature
▪ The flow rate
▪ The power consumption of the booster heater (if applicable) in
the domestic hot water tank
▪ Setup and configuration:
▪ No additional equipment needed.
▪ Only in case a booster heater is present in the system, measure
its capacity (resistance measurement) and set the capacity via
the user interface. Example: If you measure a booster heater
resistance of 17.1Ω, the capacity of the heater at 230 V is
3100W.
5.4.2 Consumed energy
You can use the following methods to determine the consumed
energy:
▪ Calculating
▪ Measuring
INFORMATION
You cannot combine calculating the consumed energy
(example: for backup heater) and measuring the
consumed energy (example: for outdoor unit). If you do so,
the energy data will be invalid.
Calculating the consumed energy
▪ The consumed energy is calculated internally based on:
▪ The actual power input of the outdoor unit
▪ The set capacity of the booster heater and the optional backup
heater
▪ The voltage
▪ Setup and configuration: To get accurate energy data, measure
the capacity (resistance measurement) and set the capacity via
the user interface for:
▪ The optional backup heater (step1 and step2)
▪ The booster heater
Measuring the consumed energy
▪ Preferred method because of higher accuracy.
▪ Setup and configuration:
▪ Requires option box EK2CB07CAV3.
▪ Requires external power meters.
▪ When using electrical power meters, set the number of pulses/
kWh for each power meter via the user interface.
INFORMATION
When measuring the electrical power consumption, make
sure ALL power input of the system is covered by the
electrical power meters.
