The Universal InfraRed (IR)-KNX device enables full integration of any air conditioner unit with an IR receiver into KNX systems.

It can emit and receive infrared signals, allowing the AC unit to be controlled by both KNX and the IR remote simultaneously. Additionally, it features two binary inputs for presence sensors or window contacts.
