5 Application guidelines

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 instructions, see the installation manual of the room
thermostat and addendum book for optional equipment.
Digital I/O PCB (EKRP1HB)
The digital I/O PCB is required to provide following signals:
▪ Alarm output
▪ Space heating On/OFF output
▪ Changeover to external heat source
For installation instructions, see the installation manual of the digital
I/O PCB and addendum book for optional equipment.
Demand PCB (EKRP1AHTA)
To enable the power saving consumption control by digital inputs
you must install the demand PCB.
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.
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 cable (EKPCCAB)
The PC cable makes a connection between the switch box of the
indoor unit and a PC. It gives the possibility to update the software of
the indoor unit.
For installation instructions, see the installation manual of the PC
cable.
Pipe bend kit (EKHVTC)
When the indoor unit is installed in a place with limited space, a pipe
bend kit can be installed to facilitate the connection to the refrigerant
liquid and gas connections of the indoor unit.
For installation instructions, see the instruction sheet of the pipe
bend kit.

5 Application guidelines
5.1

Overview: Application guidelines

The purpose of the application guidelines is to give a glance of the
possibilities of the 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 44.
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 control
▪ 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.
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?
