Universal Retrofit actuator with Uponor Vario NC FT nozzles 230V 1W IP54

The Uponor Vario Retrofit actuator is designed for automatic control of flow in hydronic underfloor heating and heating systems. It is installed on manifold valves and opens or closes the flow of the heating medium based on signals from a thermostat or controller.

The actuator operates on 230V AC and features a NC (normally closed) function — in case of power loss, the valve remains closed, ensuring system safety. Thanks to the included adapters, it is compatible not only with Uponor manifolds but also with most standard manifold valves.

Features and Benefits

• Universal retrofit solution — ideal for upgrading existing systems
• NC type — automatically closes without power
• Wide compatibility with various manifolds (via adapters)
• Low power consumption — only 1W
• IP54 protection rating — suitable for humid and dusty environments
• Easy installation without complex setup
