LG VRF CoolMaster 6000L

Control and Monitor LG VRF Air Conditioning Systems

Product Description

LG VRF adapter for Home Automation systems

CoolMaster 6000L is a versatile seamless control adapter connecting LG VRF air conditioning systems with any RS232 or USB featured devices like home PCs, embedded PCs or Home Automation controllers. Connecting such controllers through common RS232 or USB interfaces with the CoolMaster 6000L will provide end-users with full control of all LG VRF indoor units enabling them with access to HVAC’s various functionalities including diagnostic. Home Automation integrators and HVAC installers when utilising CoolMaster 6000L will not have to worry anymore about the complexity involved in understanding and working with LG internal communication line and gateways including their unique physical layer. Now, with the CoolMaster 6000L, LG  integrators will be provided only with a simple, well documented open ASCII protocol over RS232 or USB to seamlessly integrate with any Home Automation applications.

CoolMaster Icon - Plug-n-Play

Seamless easy integration with Home Automation systems and PC’s applications

Interfacing Home Automation controllers with CoolMaster 6000L is a simple and straight forward process requiring only common ASCII commands over RS232 communication line.

CoolMaster Icon - RS232

Same RS232 interface for all VRV/VRF HVAC systems

All CoolMaster models provide the same RS232 interface for all VRV/VRF HVAC systems. So for instance, a home automation application, where a LG VRF system is connected via CoolMaster 6000L, will function exactly the same way for Mitsubishi Electric VRF, Sanyo VRF, Toshiba VRF etc, when using CoolMaster models: 4000M, 2000S, 3000T respectively. No special interface adaptation will be required to migrate from one CoolMaster type to another.
