5 Application guidelines

For installation instructions, see the installation manual of the
demand PCB and addendum book for optional equipment.
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.
For installation instructions, see the installation manual of the remote
indoor sensor and 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.
Remote outdoor sensor (EKRSCA1)
By default the sensor inside the outdoor unit will be used to measure
the outdoor temperature.
As an option the remote outdoor sensor can be installed to measure
the outdoor temperature on another location (e.g. to avoid direct
sunlight) to have an improved system behaviour.

5 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.
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
page 38.
This chapter contains application guidelines for:

▪ Setting up the space heating system

▪ Setting up the domestic hot water tank
▪ Setting up the energy metering
▪ Setting up the power consumption
▪ Setting up an external temperature sensor
5.2 Setting up the space heating
system
The Daikin heat pump system supplies leaving water to heat
emitters in one or more rooms.

For installation instructions, see the installation manual of the remote
outdoor sensor.
INFORMATION
You can only connect either the remote indoor sensor or
the remote outdoor sensor.
PC configurator (EKPCCAB)
The PC cable makes a connection between the switch box of the
indoor unit and a PC. It gives the possibility to upload different
language files to the user interface and indoor parameters to the
indoor 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-
downloads/.
For installation instructions, see the installation manual of the PC
cable and "8 Configuration" on page 38.
Heat pump convector (FWXV)
For providing space heating/cooling, it is possible to use heat pump
convectors (FWXV).
For installation instructions, refer to the installation manual of the
heat pump convectors, and the addendum book for optional
equipment.

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 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 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.5.1.2] to 1.
5.2.1 Multiple rooms – Two LWT zones
This unit is designed to deliver water at 2 different temperatures. A
typical installation consists of underfloor heating at a lower
temperature and radiators at a higher water temperature.
In this document:
▪ Main zone = Zone with the lowest design temperature
▪ Additional zone = Zone with the highest design temperature
