We offer an assembly service for the actuator with fittings for this product. More information

Emergency Belimo actuator series NF for HVAC dampers or ball valves (e.g. Giacomini R250D with adapter). The actuator is designed for damper sizes up to approximately 2m². The actuator control is continuous DC 0-10 V.

Function

In the event of a power interruption, the return spring begins to rotate the actuator to the initial position. For example, in the event of a power failure, it closes the damper or ball valve. The same can be achieved in reverse, depending only on the initial position of the damper.

• The actuator can be operated manually using a locking button and a manual crank. 
• The actuator is equipped with remote communication via Belimo MP-Bus.
• The actuator is suitable for integration into the Loxone system.

Features

• The actuator is protected against overload, no end stops are necessary.
• Simple installation on the damper shaft using a universal bracket.
• Adjustable operating angle with mechanical stop.
• The actuator can be equipped with auxiliary switching contacts S...A or a feedback potentiometer.

Connectivity with the smart home system LOXONE 

The connection with the Loxone system is realised through the Belimo MP-Bus interface. To connect, you will need the product Loxone - Belimo Tree. Belimo Tree is an interface allowing the connection of up to 16 Belimo MP-Bus devices. Thanks to the native integration of MP-Bus, Belimo products become a direct part of Loxone Config and Miniserver, ensuring easy configuration and management. Belimo Tree significantly simplifies the connection of Belimo devices with the Loxone system, enabling quick and error-free setup of all functions. Its compact design and wide compatibility make this interface an ideal choice for modern and efficient building automation.
