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 kits are available for a heating
capacity of 2-6 kW, and both available for 1-phase and 3-phase
power supply specifications. When using this heater kit the optional
demand PCB is required.
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
This installation manual describes the procedures for handling,
installing and connecting all EKHBRD indoor unit models.

Typical application examples
The application examples given below are for illustration purposes
only.
Application 1
Space heating and domestic hot water heating with a single remote
controller installed in the living room.
The remote controller gives immediate feedback to the indoor unit
and by doing so it matches in a smart way the unit performance to
the demanded space heating requirements. In this way there is no
frequent start/stop of the unit or there are no too big temperature
fluctuations in the to be heated rooms. This remote controller has
also a smart logic functionality which controls the combined space
heating and domestic hot water demand (e.g. if room temperature
drops more than 3°C during domestic hot water operation, the unit
will automatically switch back to space heating). There is no remote
controller near the unit. During service maintenance an additional
remote controller can be connected by a service person.
If this option is installed it is not possible to use the remote
controller thermostat function.
