Does the Messana system integrate with third-party HVAC controls?

The Messana system offers integration options for third-party HVAC controls, designed for flexibility and modern performance:

Integration Options

1. Modbus TCP/IP

  • We support Modbus TCP/IP, allowing seamless communication with standard HVAC
    controllers and building automation systems.
  • This widely used protocol enables reliable data exchange and control interoperability.

2. REST API via RESTlet (Modern, Cloud-Friendly)

  • We provide a full-featured REST API (RESTlet) that gives developers and integrators complete access to system data and controls through HTTP requests.
  • To obtain API access, users must submit an API Key Request Form. Our support team will review your request and respond promptly.

The API documentation is published online here: Messana REST API Documentation

3. CoolMasterNet – VRF/VRV and HVAC Systems

Messana integrates with CoolMasterNet, a universal communication bridge for VRF/VRV and conventional HVAC systems.

  • Enables centralized control of mixed HVAC and hydronic systems.
  • Provides two-way communication for efficient operation and monitoring.

4. CoolMasterNet – Home Automation Systems

Messana also integrates via CoolMasterNet with popular home automation platforms such as:

  • Savant
  • Control4
  • Crestron
  • and other leading smart home ecosystems

This allows homeowners and integrators to unify Messana Controls with their whole-home automation experience.

Summary

  • Use Modbus TCP/IP for traditional building automation.
  • Use the REST API for modern, cloud-based integrations.
  • Use CoolMasterNet for both VRF/VRV + HVAC system integration and smart home platforms (Savant, Control4, Crestron, etc.)

Tip

For building automation integration, start with Modbus TCP/IP. For custom application development or cloud integration, the REST API offers maximum flexibility and ease of development. Don’t forget to request your API key via the API Key Request Form on our site.
