Multi-Function Technology

Multi-Function Technology, only from Belimo, allows you to create custom solutions for individual applications, using the same programmable actuator. You can modify voltage control, time proportional control, floating point, on/off and feedback signals too. In addition, MFT makes it easy to set parameters for running time, mechanical working range, address, status and diagnostics.


PC-Tool is a universal software application for setting, commissioning, monitoring and evaluating communications with Belimo actuators.

Hand Held Programming Devices

The ZTH directly connects to the Belimo Multi-Function Technology (MFT) series actuator offering the ability to quickly change the parameters of the actuator, such as control input, control feedback, runtime, and minimum and maximum values.
