4P402191-1A – 2015.04
Installation manual
2
Remote controller (option)
An optional secondary EKRUAHTA remote controller (with room
thermostat functionality) can be connected to the indoor unit.
Purpose is to provide the possibility to install the standard remote
controller near the unit (for service reasons), and install another
remote controller in another place (e.g. living room) to operate your
installation.
Refer to the
"Installation of the remote controller" on page 17
for
further details.
Room thermostat (option)
An optional room thermostat EKRTR or EKRTW can be connected to
the indoor unit.
Refer to the room thermostat installation manual for further details.
Heater kit (option)
An optional EKBUH heater kit can be combined with the indoor unit.
Purpose is to provide an additional heating capacity during cold
outdoor temperatures. The heater kit has a heating capacity of 6 kW,
and available for both 1-phase and 3-phase power supply
specifications. When using this heater kit, installation of the optional
demand PCB is required as well.
Refer to the heater kit installation manual for further details.
Digital I/O PCB (option)
An optional EKRP1HBA digital I/O PCB can be connected to the
indoor unit and be used to remotely monitor your system. This
address card offers 3 voltage free outputs.
Refer to the operation manual of the indoor unit and to the digital I/O
PCB installation manual for more information.
Refer to the wiring diagram or connection diagram for connecting this
PCB to the unit.
Demand PCB (option)
An optional EKRP1AHTA demand PCB can be connected to the
indoor unit. This PCB is needed when the optional heater kit EKBUH
or Daikin room thermostat EKRTR or EKRTW is installed or when
multiple set point control is used, and provides the communication
with the indoor unit.
Refer to the demand PCB installation manual for further details.
Refer to the wiring diagram or connection diagram for connecting this
PCB to the unit.
Scope of this manual

Typical application examples
The application examples given below are for illustration purposes
only.
Application examples with only 1 heat emitter and 1
heat source (EKHBRD unit)
If only 1 heat emitter (= all system has 1 water set point), it is
recommended NOT to use a balancing bottle.
Using a balancing bottle will affect the optimal pump control of the
unit and will increase the cost of the system unnecessarily.
■
Application 1
Space heating and domestic hot water heating with a single
remote controller installed in the living room.
If this option is installed it is not possible to use the remote
controller thermostat function.
