The HVAC3 – Air Condition Control Module (G4s) is a high-performance smart HVAC controller designed to manage air-conditioning systems with precision, flexibility, and energy efficiency. Built on the G4s automation platform, this module integrates seamlessly with centralized control systems for residential, commercial, and industrial buildings.

The HVAC3 module supports multiple control modes — including cooling, heating, fan speed, and temperature feedback — enabling smooth communication with split, fan coil, or VRV/VRF air-conditioning systems. It ensures reliable performance with digital and analog inputs, relay outputs, and bus communication for full system integration.

Ideal for building automation and hotel room management, the HVAC3 provides centralized control via wall panels, mobile apps, or automation software. It enhances energy efficiency, improves comfort, and simplifies maintenance with intelligent diagnostics and feedback monitoring.
