Supplier's note

  1. Technical Breakthroughs:

    • Dual-Pipe Compatibility: The 2/4-pipe design eliminates the need for separate thermostats, reducing installation costs by up to 30%.
    • Keycard Security: The 4-pipe model’s access control meets ISO 18000-3 standards, ideal for hotels and offices.
    • 0-10V Modulation: Precision temperature control (±0.5°C) ensures energy savings of 15–25% compared to traditional thermostats.

  2. Version Selection Guide:

    • Base Model (2-Pipe): Best for residential or small commercial spaces without advanced security needs (e.g., apartments, villas).
    • Advanced Model (4-Pipe): Suited for mid-sized facilities requiring keycard access (e.g., gyms, supermarkets).
    • Pro Model: Recommended for high-security or industrial environments (e.g., hospitals, data centers) needing remote monitoring and premium durability.

*Pro Model’s expanded terminals accommodate smart HVAC ecosystems, enabling IoT integration for predictive maintenance.
