Lämmityssäädin Busch-Jaeger 6224/2.0, uppoasennus, 24 V, LCD, 71×71×30 mm

The Busch-Jaeger 6224/2.0 is a flush-mounted heating actuator with an integrated LCD display, designed to control room heating valves within smart-home and building-automation setups. It operates at 24 V and its compact dimensions (71×71×30 mm) make it suitable for standard mounting boxes. The unit provides direct valve actuation and an informative display for status and basic adjustments, enabling precise control of radiator or underfloor heating actuators.

Advantages

The device offers compact flush-mounted installation and a clear LCD for on-site readout, allowing installers and users to verify status without additional tools. Operating at low-voltage 24 V improves electrical safety in domestic installations and simplifies integration with common control systems. Its standardized dimensions facilitate replacement or retrofit in existing switch boxes while providing consistent mechanical and electrical interfaces for reliable valve control.

Key specifications

How to use

Install the actuator into a compatible flush-mounted box following local electrical codes and the manufacturer's wiring guidelines. Connect the 24 V supply and control signals from the room thermostat or building controller. After mounting and wiring, use the integrated LCD to confirm power and observe valve position or status indicators. Commission the actuator by following system-specific procedures for calibration and control integration so that the actuator responds correctly to temperature setpoints and control commands.

Recommendations

Use the actuator with compatible valves and control systems rated for 24 V operation. Ensure secure electrical connections, protect against moisture where required, and perform initial commissioning and periodic checks to verify correct operation and to maintain energy-efficient temperature regulation.
