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.
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 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.

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.

5 Compressor
6 Pump
7 Shut-off valve
8 Motorized 3-way valve

9 Domestic hot water tank
(optional)
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.
