AK-AC-KNX-8: Arçelik VRF systems to KNX Gateway, for 8 indoor units

IntesisBox KNX – Arcelik AC is a communication gateway for the integration of Arçelik air conditioning systems into KNX TP-1 (EIB).

IntesisBox KNX continuously polls (reads) the Arçelik PI485 bus for all configured signals and keeps the updated status of all of them in its memory ready to be served when requested from KNX.

On the KNX side, IntesisBox simulates a KNX device and acts as if it was one more device into the KNX system. 

The IntesisBox's KNX EIB interface connects directly to the EIB bus and is optoisolated from the rest of the internal electronics. Any point in IntesisBox can be configured individually for different functionality.
To allow read requests, to allow write requests, to automatically send a write request to the KNX bus when its value changes, and to send a read request to the KNX bus when IntesisBox starts-up or after a bus reset.

For each point, one main group address and different listening group addresses can be defined. This useful feature allows actions on the same internal point from multiple KNX group addresses.
