EPGA11~ EAVH/9W
Daikin Altherma – Low temperature split
4P556070-1 – 2019.02
▪ 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 and
Heat pump convector (FWXV)
For installation instructions, refer to the installation manual of the
heat pump convectors, and the addendum book for optional
equipment.
LAN adapter for smartphone c Smart Grid applications
(BRP069A61)
You can install this LAN adapter to:
▪ Control the system via a smartphone app.
▪ Use the system in various Smart Grid applications.
For installation instructions, see the installation manual of the LAN
adapter.
LAN adapter for smartphone control (BRP069A62)
You can install this LAN adapter to control the system via a
smartphone app.
For installation instructions, see the installation manual of the LAN
adapter.
Universal centralised controller (EKCC8-W)
Controller for cascade control.

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.
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 the power consumption control
▪ 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 Emergency [9.5] to Automatic.
NOTICE
An overpressure bypass valve can be integrated in the
system. Keep in mind that this valve might not be shown
on the illustrations.
