iSMA-B-FCU-LLfully programmable controller, is built with the aim of controlling the FCU. The controller is factory-equipped with the two most popular open communication protocols Modbus ASCII/RTU and BACnet MSTP, which are selected using DIP switches.

To minimise time and simplify commissioning process the controller is delivered with universal application, which supports the most popular types of FCU. Dedicated DIP-switch allows to adjust parameters of the application. Additionally, in the BACnet protocol, the application  has the built-in function which allows automatically to bind Master and Slave controllers in the groups
