N/A For proportional modulation of dampers in HVAC systems. The AHKX24-MFT-100 provides electrical power off operation for reliable fail-safe application.
The default parameters for 2 to 10 VDC applications of the AHKX24-MFT-100 actuator are assigned during manufacturing. If necessary, custom versions of the actuators can be ordered. The parameters can be changed by: pre set or custom configurations provided by Belimo or on-site using the PC-Tool software.
