5 Application guidelines

4.4 Possible options for the indoor
unit
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.
User interface used as room thermostat (BRC1HHDA)
▪ The user interface used as room thermostat can only be used in
combination with the user interface connected to the indoor unit.
▪ The user interface used as room thermostat needs to be installed
in the room that you want to control.
For installation instructions, see the installation and operation
manual of the user interface used as room thermostat.
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.
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.
Heat pump convector (FWXV)
For providing space heating/cooling, it is possible to use heat pump
convectors (FWXV).
For installation instructions, see the installation manual of the heat
pump convectors, and the addendum book for optional equipment.
Room thermostat (EKRTWA, EKRTR1)
You can connect an optional room thermostat to the indoor unit. 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 instructions, see the installation manual of the room
thermostat and addendum book for optional equipment.

Brine filling kit (KGSFILL2)
Brine filling valve kit for flushing, filling, and draining the brine circuit.
Current sensor (EKCSENS)
Current sensor for power limitation. For installation instructions, see
the installation manual of the current sensor.
Hydro module (EKGSHYDMOD)
Hydro module replacement.
For installation instructions, see the installation manual of the hydro
module.
Power cable with connector for Germany (EKGSPOWCAB)
Power cable for split power supply layout, needed for installations in
Germany.
For installation instructions, see the installation manual of the power
cable.
Multi-zoning base unit and wired thermostats (EKWUFHTA1V3,
EKWCTRDI1V3, EKWCTRAN1V3)
Multi-zoning base unit (EKWUFHTA1V3) and thermostats for multi
zone control of underfloor heating and radiators. Both digital
(EKWCTRDI1V3) and analog (EKWCTRAN1V3) wired thermostat
options are available.
For more information, see the installation manual of the multi-zoning
base unit and the applicable thermostat.
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
"10 Configuration" [ 4 55].
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
▪ Setting up passive cooling
▪ Setting up the brine low pressure switch
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 heat pump system?
