For installation instructions, see
"7.6.8 To connect the user
interface" on page 31
.
Simplified user interface (EKRUCBS)
▪ The simplified user interface can only be used in combination with
the main user interface.
▪ The simplified user interface acts as room thermostat and needs
to be installed in the room that you want it to control.
For installation instructions, see the installation and operation
manual of the simplified user interface.
Room thermostat (EKRTWA, EKRTR1, RTRNETA)
You can connect an optional room thermostat to the indoor unit. This
thermostat can either be wired (EKRTWA) or wireless (EKRTR1and
RTRNETA). Thermostat RTRNETA can only be used in heating-only
systems.
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.
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.
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

downloads/
.
For installation instructions, see the installation manual of the PC
cable and
"8 Configuration" on page 34
.
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.
Cable for brine pressure switch connection (EKGSCONBP1)
Depending on the applicable legislation, you might have to install a
brine pressure switch (field supply). To connect the brine pressure
switch to the unit, you can use the cable for brine pressure switch
connection.
For installation instructions, see the installation manual of the cable
for brine pressure switch connection.
NOTICE
Daikin recommends to use a mechanical brine pressure
switch. If an electrical brine pressure switch is used,
capacitive currents might disturb the flow switch operation
causing an error on the unit.
Brine filling kit (KGSFILL)
Brine filling valve kit for flushing, filling, and draining the brine circuit.
