thermostat can either be wired (EKRTWA) or wireless (EKRTR1).
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/cooling On/OFF output
▪ Changeover to external heat source
▪ Only for EHVH/X16 models: Control signal for bottom plate heater
kit EKBPHTH16A.
For installation instructions, see the installation manual of the digital
I/O 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.
Remote outdoor sensor (EKRSCA1)
By default the sensor inside the outdoor unit will be used to measure
the outdoor temperature.
As an option the remote outdoor sensor can be installed to measure
the outdoor temperature on another location (e.g. to avoid direct
sunlight) to have an improved system behaviour.
For installation instructions, see the installation manual of the remote
outdoor sensor.
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 Daikin Extranet.
For installation instructions, see the installation manual of the PC
