theben AC IR1 KNX Split Unit Gateway (SKU 4940320)

Description

Introduction

The theben AC IR1 KNX (Item no. 4940320) is a dedicated split unit gateway engineered to integrate infrared-controlled climate split devices directly into a KNX building automation network. Designed for flush-mounted installation, this 1-channel gateway provides direct, reliable climate control without requiring direct hardware modifications to the air conditioning equipment. This device is part of our KNX system components range.

Equipped with an extensive IR database containing code sets for over 500 different split unit models and remote controls, the AC IR1 KNX simplifies integration for system integrators and electrical contractors. Powered entirely via the KNX bus with a low current draw of less than 12 mA, it offers an efficient and clean solution for smart climate management in residential and commercial projects.
