## Long description

Wireless radiator actuator Rademacher DuoFern 94331 (2nd Generation) supplied as a customer return. This compact electric valve drive is designed to replace or retrofit thermostatic radiator valves on compatible valve interfaces and to communicate wirelessly via the DuoFern radio protocol.

How to use
Install the actuator by removing the existing thermostatic head and mounting the DuoFern actuator on the compatible valve interface according to the valve manufacturer’s instructions.

After pairing, configure temperature setpoints, schedules or on/off behavior via the DuoFern master device or compatible thermostat. Verify proper movement of the actuator and that the valve opens and closes in response to commands before finalising installation.
Usage recommendations
