NOTICE
▪ The illustrations in the application guidelines are meant
for reference only, and are NOT to be used as detailed
hydraulic
diagrams.
The
detailed
hydraulic
dimensioning and balancing are NOT shown, and are
the responsibility of the installer.
▪ For more information about the configuration settings to
optimize heat pump operation, see
.
This chapter contains application guidelines for:
▪ Setting up the space heating/cooling system
▪ Setting up an auxiliary heat source for space heating
▪ Setting up the domestic hot water tank
▪ Setting up the energy metering
▪ Setting up an external temperature sensor
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.
NOTICE
If an external room thermostat is used, the external room
thermostat will control the room frost protection. However,
the room frost protection is only possible if the leaving
water temperature control on the unit's user interface is
turned ON.
INFORMATION
In case an external room thermostat is used and room frost
protection needs to be guaranteed in all conditions, then
you have to set auto emergency [A.6.C] to 1.

▪ The under floor heating or radiators are directly connected to the
outdoor unit – or to the backup heater, if there is one.
▪ The room temperature is controlled by the user interface, that is
connected to control box EKCB07CAV3. Possible installations:
▪ Control box EKCB07CAV3 is installed in the room and the user
interface is used as room thermostat.
▪ Control box EKCB07CAV3 is installed indoors, close to the
outdoor unit + user interface installed in the room and used as
room thermostat.

Benefits
▪
Cost effective.
You do NOT need an additional external room
thermostat.
▪
Highest comfort and efficiency
. The smart room thermostat
functionality can decrease or increase the desired leaving water
temperature based on the actual room temperature (modulation).
This results in:
▪ Stable room temperature matching the desired temperature
(higher comfort)
▪ Less ON/OFF cycles (more quiet, higher comfort and higher
efficiency)
▪ Lowest possible leaving water temperature (higher efficiency)
▪
Easy
. You can easily set the desired room temperature via the
user interface:
▪ For your daily needs, you can use preset values and schedules.
▪ To deviate from your daily needs, you can temporarily overrule
the preset values and schedules, use the holiday mode…
