Traditional thermostats use mechanical relays that create clicking sounds. Our HDC unit uses solid-state electronic switching and is installed hidden in the ceiling (near the FCU), physically isolating any operational sound. This ensures a 0dB silent environment in the sleeping area, significantly enhancing guest comfort.

Yes. The HDC acts as a "Universal HVAC Logic Base." It handles complex driving tasks (3-speed/EC fans, valves) and thermal logic. Your smart panels only need to interface via RS485 (Modbus), Zigbee, or KNX. This allows smart home brands to provide professional climate control without deep HVAC engineering expertise.

Most modulating valves and smart panels require a 24V power supply, which usually necessitates an external transformer. The HDC features a built-in power hub that directly provides 24V DC. This eliminates the cost of extra transformers, saves space in the control box, and simplifies the wiring process for installers.

Absolutely. The HDC is designed for full terminal compatibility. It supports traditional 3-speed AC fans and modern high-efficiency 0-10V EC fans. It also manages various valves (On/Off or Proportional) and supports heat source linkage, making it a "one-size-fits-all" controller for diverse projects.

To ensure seamless integration into smart buildings, our system natively supports BACnet MS/TP, KNX, and HBS (Home Bus System). For wireless IoT applications, we offer stable WiFi and Zigbee 3.0 versions, ensuring compatibility with global building automation and smart home standards.
