(一)Core Parameters

1. Technical Performance Parameters

• Power Supply & Control: Rated operating voltage 230V AC, compatible with civil and industrial standard power supply circuits without additional transformers; supports dual modes of proportional control and On/Off switching control, can receive 0-10V/4-20mA analog signals from thermostats, independent control design without relying on bus systems, suitable for single-point temperature control scenarios.
• Drive & Protection Functions: Designed for small-caliber thermoelectric valves, compatible with DN≤50 ball valves and butterfly valves (torque ≤5Nm) to achieve precise valve opening regulation; built-in PTC thermistor overheating protection and stall protection functions, automatically cuts off the drive circuit in case of overload, and can be manually reset after cooling to extend the service life of valves and drives.
• Operation & Display: Integrated single-color status LED indicator to intuitively feedback power on/off, valve operation and fault alarm status; equipped with local manual adjustment knob for manual control of valve opening and closing during power failure or debugging, balancing automatic control and emergency operation needs.
• Installation & Protection: Adopts snap-on wall-mounted installation, compatible with standard mounting brackets, can be deployed directly close to valves to save space; IP54 protection rating (dustproof and waterproof), operating temperature -5℃~55℃, suitable for semi-exposed and humid environments such as equipment rooms, pipe wells and underground garages.

2. Appearance & Material Parameters

• Material & Craftsmanship: The main body is made of flame-retardant engineering plastic, manufactured by integrated injection molding, with high mechanical strength and excellent temperature and moisture resistance, capable of withstanding temperature differences and slight moisture erosion around HVAC pipelines; terminal blocks adopt copper core nickel-plated design with low contact resistance and anti-loose buckles to ensure stable transmission of power supply and control signals.
• Color Specification: Full black matte appearance, compact and simple structure, size suitable for small-caliber valve installation space, no redundant decorative elements, strong industrial texture, can coordinate with various HVAC equipment, combining practicality and dirt resistance.
