Programmable fan-coil (FCU) controller with pre-loaded application

Product Details

The fully programmable controller FCU, is built with the aim of controlling the FCU. The controller is factory-equipped with the two most popular open communication protocols Modbus RTU/ASCII and BACnet MS/TP, which are selected using DIP switches. To minimize time and simplify the commissioning process the controller is delivered with a default application, which supports the most popular types of FCU. A dedicated DIP switch allows for adjusting the parameters of the application. Additionally, in the BACnet protocol, the application has a built-in function that allows automatically to bind Master and Slave controllers in the groups (20 groups on the bus, up to 6 devices in one group).
If the default application does not meet the project requirements, it can be modified or created from scratch by the freeware Tool. Changing the application is possible in real-time by USB. There are three hardware versions with different types of Triac Outputs and power supplies.
