Multiple Working Modes and Flexible Wiring: The thermostat supports several operation modes with versatile wiring options. In singlewire mode, the valve stops while the fan continues to run; in dualwire mode, both the valve and the fan stop when required. This provides reliable control for different ventilation and safety needs. External Embedded Installation: Designed for external embedded mounting with a standard 86 type installation cassette, ensuring a straightforward and clean installation process. Long Service Life and Durable Operation: The thermostat is rated for more than 100,000 cycles at full load, and the manual operation switch is rated for more than 60,000 cycles, delivering durable performance over time. Stable Performance and Quality Construction: Features an attractive appearance and a comfortable hand feel, with stable operation. The temperature sensing element uses an accurate metal bellows for dependable temperature response. Key Specifications and Attributes: Function: Controls valve and fan operation with multiple wiring options Compatibility: Standard 86 type installation cassette for easy integration Size/Installation: External embedded installation suitable for 86type panels Material/Sensing: Metal bellows temperature sensor for precise sensing Performance: cycle life (thermostat >100,000 cycles; manual switch >60,000 cycles), stable and reliable operation Use Scenarios: Office and commercial HVAC systems: Integrate with dampers and supply/ fans to maintain target airflow and temperature with flexible wiring modes for safety and efficiency.
