1 Introduction
The iSMA-B-FCU is a fully programmable controller, 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 MS/TP, which are selected using DIP switches.
To minimize time and simplify the commissioning process the controller is delivered with
universal application, which supports the most popular types of FCU. Dedicated DIP
switch allows adjusting 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
groups.
In cases if the standard 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 (iSMA-B-FCU-HH, iSMA-B-FCU-HL, iSMA-B-FCU-LL).
