## Long description

Wireless radiator actuator Rademacher DuoFern 94331 (2nd Generation) is a motorised valve actuator designed to be mounted on standard thermostatic radiator valves to enable remote and automated control of central heating.

Its retrofit-friendly mounting fits common valve types and enables installation without extensive plumbing work. The actuator's design focuses on reliable operation and straightforward setup with compatible Rademacher devices and partners that support the DuoFern protocol.
