Scope Of This Manual; Model Identification; Typical Application Examples; Application Examples With Only 1 Heat Emitter - Daikin EKHBRD016ABV1 Installation Manual

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.
If this option is installed it is not possible to use the remote
controller thermostat function.
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

This installation manual describes the procedures for handling,
installing and connecting all EKHBRD indoor unit models.
NOTE Installation of the ERSQ or ERRQ heat pump outdoor
is described in the outdoor unit installation manual.
Operation of the indoor unit is described in the indoor
unit operation 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.

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.
