Global Control 5 provides advanced building automation solutions developed by highly experienced specialists. iSMA Controllers including the iSMA – B – FCU controller is equipped with open communication protocols: Modbus ASCII/RTU and BACnet MSTP. By providing a large number of inputs and outputs, these controllers are able to communicate with a large number of other devices.
The iSMA-B-FCU is able to support the most popular types of FCU’s straight out of the box. With its dedicated DIP-switches, parameters can be adjusted as required.
