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 the 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.
