iSMA-B-FCU-HH | GC5

Room controllers

To meet the market needs, Global Control 5 built a range of fully programmable room controllers and wall panels. To minimise time and simplify commissioning process the controller is delivered with universal application, which supports the most popular types of FCU. The controller is factory-equipped with the two most popular open communication protocols Modbus and BACnet.

iSMA-B-FCU-HH

iSMA-B-FCU-HH, fully 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

In te case, if the application does not meet the project requirements, it can be modified or created from scratch. Changing of the application is possible in real-time by USB port. There are three hardware versions which have  different types of Triac Outputs and power supply.
