Product information

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. The unit uses the DuoFern wireless protocol for communication with compatible gateways and thermostats. This returned-from-stock device provides motor-driven valve position control to regulate room temperature without changing existing pipework or valve bodies, making it suitable for retrofit and smart-home environments.

Advantages

The actuator delivers automated valve control through a compact, battery-powered motor, allowing precise adjustment of radiator flow for consistent temperature management. Wireless DuoFern connectivity enables integration with supported control systems for scheduled, manual or sensor-driven operation. 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.

Suitable for

  • Automating central heating radiators in residential apartments and houses
  • Retrofitting traditional thermostatic radiator valves for smart-home control
  • Integrating radiator control into a DuoFern-based heating or home automation system
  • Rooms requiring zone-based temperature regulation such as bedrooms, living rooms or offices

Key specifications

  • Wireless protocol: DuoFern
  • Power source: battery-operated motor (replaceable batteries)
  • Mounting: fits standard thermostatic radiator valve interfaces for retrofit installation
  • Function: motorised valve travel to adjust radiator flow for temperature control
  • Control modes: supports remote commands, schedules and sensor-driven adjustments when connected to a compatible controller

How to use

Attach the actuator to the thermostatic radiator valve following the adapter and mounting procedure applicable to the valve type. Insert batteries and pair the actuator with a DuoFern-compatible gateway or thermostat according to the controller’s pairing instructions. Once paired, use the control unit or app to configure operation modes, schedules, and temperature setpoints. Regularly check battery status and replace batteries as prompted to maintain reliable operation.

Usage recommendations

For best results, install the actuator on radiators in easily accessible locations and avoid mounting behind curtains or furniture that can obstruct temperature sensing and wireless signal. Use compatible DuoFern controllers and follow manufacturer pairing and safety instructions. Verify valve compatibility and, if necessary, use the correct adapter to ensure secure mounting and accurate valve travel.
