INFORMATION
▪ If control box EKCB07CAV3 is NOT part of the system,
connect the user interface directly to the outdoor unit.
▪ If control box EKCB07CAV3 is part of the system, you
can also connect the user interface to the control box.
Room thermostat (EKRTWA, EKRTR1)
You can connect an optional room thermostat to control box
EKCB07CAV3. This thermostat can either be wired (EKRTWA) or
wireless (EKRTR1).
For installation instructions, see the installation manual of the room
thermostat and addendum book for optional equipment.
Remote sensor for wireless thermostat (EKRTETS)
You can use a wireless indoor temperature sensor (EKRTETS) only
in combination with the wireless thermostat (EKRTR1).
For installation intructions, see the installation manual of the room
thermostat and addendum book for optional equipment.
PC configurator (EKPCCAB)
The PC cable makes a connection between the switch box of the
outdoor unit (or that of control box EKCB07CAV3) and a PC. It gives
the possibility to upload different language files to the user interface,
and parameters to the outdoor unit. For the available language files,
contact your local dealer.
The software and corresponding operating instructions are available
on
http://www.daikineurope.com/support-and-manuals/software-
For installation instructions, see the installation manual of the PC
cable, the
book for optional equipment.

Possible options for the option box
Remote indoor sensor (KRCS01-1)
By default the internal user interface sensor will be used as room
temperature sensor.
As an option the remote indoor sensor can be installed to measure
the room temperature on another location.
The remote indoor sensor is connected to option box
EK2CB07CAV3. For installation instructions, see the installation
manual of the remote indoor sensor and the addendum book for
optional equipment.
INFORMATION
▪ The remote indoor sensor can only be used in case the
user interface is configured with room thermostat
functionality.
▪ You can only connect either the remote indoor sensor
or the remote outdoor sensor.

Application guidelines
5.1
Overview: Application guidelines
The purpose of the application guidelines is to give a glance of the
possibilities of the Daikin heat pump system.
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 energy metering
▪ Setting up the power consumption
▪ 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.
