Nest thermostats are designed to work with most 24V systems, including LG systems. However, there are certain LG systems that may not be compatible with Nest thermostats, such as those with wired remote sensors, micro-controller based systems, zone relay or control panels, or incompatible system wiring. This comprehensive guide will explore the compatibility of Nest thermostats with LG systems, providing technical details and expert-level insights to help you determine if your LG system is compatible and how to successfully integrate a Nest thermostat.
Compatibility Considerations
Nest Learning Thermostat Compatibility
The Nest Learning Thermostat is compatible with systems that have one or two stages of cooling. It is important to note that the Nest Learning Thermostat may not be compatible with LG systems that have more than two stages of cooling or systems that utilize wired remote sensors, micro-controller based controls, zone relay panels, or have incompatible system wiring.
Nest Thermostat E Compatibility
The Nest Thermostat E is compatible with systems that have one stage of heating, one stage of cooling, and an additional stage of either heating or cooling. Similar to the Nest Learning Thermostat, the Nest Thermostat E may not be compatible with LG systems that have more complex configurations or utilize wired remote sensors, micro-controller based controls, zone relay panels, or have incompatible system wiring.
International System Compatibility
Some international LG systems, such as Buderus boilers, may require the use of relay panels in order to be installed with standard American or Canadian thermostat wiring. It is essential to carefully review the compatibility of your specific LG system with the Nest thermostat you intend to use.

To determine if your LG system is compatible with a Nest thermostat, you can use the online Compatibility Checker provided by Google. This tool will guide you through your wiring configuration and help you determine if your system is compatible. If your system is compatible, the tool will provide recommendations for the appropriate Nest thermostat model.
Specific LG Mini Split Configurations
For users looking to integrate a Nest thermostat with an LG mini split system using LG’s latest Dry Contact PDRYCB320, there are discussions on forums such as Reddit where users have shared their experiences and ideas. However, it’s important to note that the success of these configurations may vary depending on the specific LG system and Nest thermostat model being used.
Technical Considerations
Wiring Compatibility
Nest thermostats are designed to work with 24V systems, which includes most LG systems. However, it’s crucial to ensure that the wiring in your LG system is compatible with the Nest thermostat’s wiring requirements. This may involve identifying the correct terminals, such as R, C, W, Y, and G, and ensuring that the wiring is properly connected.
System Complexity
As mentioned earlier, Nest thermostats may not be compatible with LG systems that have more than two stages of cooling or utilize wired remote sensors, micro-controller based controls, zone relay panels, or have other complex configurations. It’s essential to carefully review the technical specifications of your LG system to ensure compatibility with the Nest thermostat.
Dry Contact Integration
For LG mini split systems using the Dry Contact PDRYCB320, users have reported success in integrating Nest thermostats by utilizing the dry contact feature. This involves connecting the Nest thermostat to the dry contact terminals on the PDRYCB320 module, which allows the Nest thermostat to communicate with the LG mini split system. However, the specific configuration and settings may vary depending on the LG system and Nest thermostat model.
Troubleshooting and Support
If you encounter any issues during the installation or integration of a Nest thermostat with your LG system, there are several resources available to help you troubleshoot and resolve the problem.
Online Forums and Communities
Platforms like Reddit, the Google Nest Community, and various HVAC-focused forums often have discussions and user-generated content related to integrating Nest thermostats with LG systems. These communities can be valuable sources of information, as users may share their experiences, tips, and solutions to common problems.
Manufacturer Support
Both Nest and LG offer customer support channels, such as phone, email, or online chat, where you can reach out for assistance. The manufacturers’ technical support teams can provide guidance on compatibility, installation, and troubleshooting specific to your LG system and Nest thermostat model.
Professional Installation
If you’re unsure about the compatibility or installation process, it’s recommended to consult with a professional HVAC technician. They can assess your LG system, determine the appropriate Nest thermostat model, and handle the installation and integration process to ensure a seamless and reliable setup.
By following the guidelines and technical considerations outlined in this comprehensive guide, you can determine if your LG system is compatible with a Nest thermostat and successfully integrate the two for improved energy efficiency and smart home automation.
