1. Presentation
INKNXDAI001I000 allows a complete and natural integration of
Daikin air conditioners with KNX control systems.
Compatible with all models of Domestic line of air conditioners.
Main features:
• Reduced dimensions. Installation even inside the A.C. indoor unit.
• Quick and non visible installation.
• External power not required.
• Direct connection to the KNX EIB bus.
• Direct connection to the AC indoor unit.
• Fully KNX interoperable, configuration from ETS.
• Multiple objects for control (of different types: bit, byte, characters…).
• Control of the AC unit based in the ambient temperature read by the own AC unit, or in
the ambient temperature read by any KNX thermostat.
• Total Control and Monitoring of the AC unit from KNX, including monitoring of AC unit’s
state of internal variables, running hours counter (for filter maintenance control), and
error indication and error code.
• AC unit can be controlled simultaneously by the IR remote control of the AC unit and by
KNX.
• Up to 2 scenes can be saved and executed from KNX, fixing the desired combination of
Operation Mode, Set Temperature, Fan Speed, and Swing in any moment by using a
simple Switching type object.

2. Connection
The interface comes with a cable (1 meter long) for direct connection to the internal control
board of the AC indoor unit.
Connection of the interface to the AC indoor unit:
Disconnect mains power from the AC unit. Open the front cover of the indoor unit in order
to have access to the internal control board. In the control board locate the socket
connector marked as:
S21 in Domestic line models
Using the cable that comes with the interface, insert its smaller connector into the socket of
the INKNXDAI001I000 marked as AC Unit, and the other connector, the biggest one, into
the socket S21 of the AC unit's control board. Fix the INKNXDAI001I000 inside or outside
the AC indoor unit depending on your needs – remember that INKNXDAI001I000 must be
also connected to the KNX bus. Close the AC indoor unit's front cover again.
IMPORTANT: Do not modify the length of the cable supplied with the interface, it may affect
to the correct operation of the interface.
Connection of the interface to the KNX bus:
Disconnect power of the KNX bus. Connect the interface to the KNX TP-1 (EIB) bus using
the KNX standard connector (red/grey) of the interface, respect polarity. Reconnect power
of the KNX bus.

3. Configuration and setup
This is a fully compatible KNX device which must be configured and setup using standard
KNX tool ETS.
ETS project for this device can be donwloaded from:
https://intesis.com/products/ac-interfaces/daikin-gateways/daikin-knx-ac-dk-ac-knx-1
Please consult the README.txt file, located inside the downloaded zip file, to find
instructions on how to install the database.
IMPORTANT: Do not forget to select the correct model of AC indoor unit connected to the
interface, this is in "Parameters" of the device in ETS.
