KNX communication modules for LG air conditioners

KNX communication modules for LG air conditioners

This category includes KNX communication modules designed for LG VRF air conditioning systems, allowing seamless integration into KNX-based building automation environments. These modules act as gateways between the HVAC system and master controllers using the KNX TP-1 (EIB) protocol, enabling remote monitoring and control of key parameters such as temperature, mode, fan speed and system status. As a result, facility managers and integrators can achieve more precise climate control, improved energy efficiency, and reduced maintenance effort.

A complete list of compatible LG indoor units is available in the official documentation: COMPATIBILITY LIST.

Features and functions of LG KNX gateway communication modules

The LG KNX communication modules allow simultaneous integration of up to 64 indoor units, depending on the installation. Each module supports bidirectional data exchange, meaning that HVAC settings can be adjusted remotely while real-time feedback – such as operating status, error codes, and active alarms – is reported back to the KNX system. Key operating variables like temperature setpoint, mode, fan speed, and even internal counters such as filter maintenance hours can be accessed and controlled through the KNX network.

These modules are fully compatible with ETS configuration software, which simplifies setup and commissioning. Each data point (DPT) is assigned a KNX group address that can be easily mapped in automation scenarios. Whether the goal is to provide local room control or full integration with complex building management logic, the gateway offers flexibility and scalability for any KNX environment.

A key advantage of the LG KNX gateway is its ability to work simultaneously with both infrared remotes and KNX control signals. This allows end-users to retain familiar control interfaces, while facility managers or building automation systems can override or schedule changes centrally. The module also supports configuration via DIP switches, eliminating the need for software tools in basic setups – ideal for quick deployments.

Integrating KNX thermostats offers further advantages. The thermostat’s own temperature sensors can be used to control the HVAC unit more precisely. Additional logic features like window open detection, presence detection, and time scheduling can reduce energy usage significantly, especially in office buildings, hotels, and shared spaces. Modules also support scene-based operation, enabling full integration with lighting, shading, and access systems through KNX group commands.

With certified KNX compliance, these modules guarantee interoperability with any device or system on the KNX network. The gateway’s wide support for DPTs (datapoint types) ensures compatibility with different control interfaces, visualization systems, and automation routines. Mounting options include standard wall installation or DIN rail mounting (TH35), allowing easy incorporation into control panels or distribution boxes.

LG KNX modules are an ideal solution for building engineers, HVAC contractors, system integrators and energy managers seeking a reliable and standards-compliant method to control air conditioning systems through a unified building automation platform. Their stability, low energy demand, and robust design make them suitable for use in residential, commercial, and industrial applications alike.
