Product Details
For proportional modulation of dampers and control valves in HVAC systems. The AFB24-MFT provides mechanical spring return operation for reliable fail-safe application.
Default parameters for 2 to 10 VDC applications of the AFB24-MFT actuator are assigned during manufacturing. If required, custom versions of the actuator can be ordered. The parameters noted in the Technical Data table are variable. These parameters can be changed by three means:
- Pre-set configurations from Belimo
- Custom configurations from Belimo
- Configurations set by the customer using the MFT PC tool (version 3.4 or higher) software application.
- Handheld ZTH-GEN
