MTN639126 Schneide 24V Thermoelectric Valve Drive HVAC Automation Unit

• Power Supply & Control: 24V DC rated operating voltage, compatible with building automation system power circuits. Supports proportional and On/Off control modes with 0-10V/4-20mA analog signal input. Independent control design enhances electrical safety for single-point temperature control applications.
• Drive & Protection: Designed for small-caliber thermoelectric valves (DN≤50, torque ≤5Nm). Built-in PTC thermistor overheating protection and stall protection with automatic circuit cutoff and manual reset capability.
• Operation & Display: Integrated LED status indicator for power, operation, and fault feedback. Manual adjustment knob enables valve control during power failure or system debugging.
• Installation & Protection: Snap-on wall-mounted installation with IP54 rating. Operating temperature range -5℃ to 55℃, suitable for semi-exposed and humid environments including equipment rooms and underground garages.

• Material & Construction: Flame-retardant engineering plastic body with integrated injection molding for high mechanical strength and temperature/moisture resistance. Copper core nickel-plated terminal blocks ensure stable power and signal transmission.
• Color & Design: Full black matte finish with compact, industrial design. Space-efficient dimensions suitable for small-caliber valve installations with practical, dirt-resistant properties.

Ideal for high-end residential communities and villas, controlling thermoelectric valves in floor heating and wall-mounted air-conditioning water systems. 24V DC low-voltage operation ensures safety near bedrooms and children's areas. IP54 protection suits humid environments like bathrooms, while manual adjustment facilitates owner debugging and overheating protection prevents valve damage.

Suitable for HVAC systems in office buildings, shopping malls, and hotels. Complies with commercial safety standards for concealed ceiling installation. Snap-on mounting enables batch deployment and maintenance. Proportional control optimizes energy efficiency while IP54 protection handles complex environments like pipe wells and equipment mezzanines.

Perfect for data centers, precision laboratories, and industrial facilities requiring high electrical safety. 24V DC operation eliminates high-voltage risks and integrates with centralized power systems. Flame-retardant materials and overheating protection enhance safety, while manual adjustment supports maintenance without disrupting core equipment operations.

Designed for hospitals, nursing homes, and kindergartens with strict safety requirements. 24V low voltage prevents electric shock hazards in medical and educational settings. IP54 rating withstands cleaning and disinfection moisture. Dual protection with overheating safety and manual emergency operation ensures environmental comfort in specialized applications.
