Universal Retrofit actuator with Uponor Vario NC FT 24V 1W IP54 nozzles

The Uponor Vario Retrofit actuator is a universal thermo-electric actuator designed for automatic control of flow in hydronic underfloor heating and heating systems. It is installed on manifold valves and operates together with a thermostat and controller, opening or closing circuits depending on room temperature.

The actuator operates on 24V AC/DC and features a NC (normally closed) function — in case of power loss, the valve remains closed, ensuring safe system operation. Thanks to the included adapters, it is suitable for various manifold types, making it an ideal solution for both new installations and retrofit applications.

Features and Benefits

• Universal retrofit solution — suitable for most manifolds
• NC type — closes automatically without power
• Enhanced operational safety
• Low power consumption — only 1W
• IP54 protection rating — resistant to dust and moisture
• Quick and easy installation
