FlowCon Energy FIT System DN15-250 1B95086 - 03/2021 Quick Start-Up Sequence FlowCon recommends performing first start-up sequence of the FlowCon Intelligent Interface locally in the equipment room before installing the FlowCon Intelligent Interface in the system. All you need is a PC and an adaptor (e.g. a USB to RS485 half-duplex without Echo, 120Ω termi-nation) and a power supply to set 3 basic parameters for the FlowCon FIT System to communication with the BMS. The rest of the FlowCon FIT System (PICV valve incl. actuator and sensors) can easily and if required be installed beforehand.

Connect 24V AC/DC and GND and turn on power (middle gland). pressure sensors) or 4 (FN/FH actuator with pressure sensors). Setting should be according to system values and FlowCon instruction variables. Finally, label or in other way mark each FlowCon Intelligent Interface to specific location and identification in the project. From your BACnet interface program (e.g. YABE) connect to the Intelligent Interface and select parameters (default values are underlined): • MSV.1 Baud Rate: 9600, 19200, 38400, 57600, 76800 or 115200 • MSV.2 MS/TP MAC Address: 000-127 and • MSV.5 FIT Configuration: 1 (SM.0.0.0.5/6), 2 (SM.0.0.0.3/4), 3 (FN/FH actuator without Please wait 60 sec before switching power off to allow versatile memory to receive the MSVchanges. The MSV-changes will be implemented when the Intelligent Interface is re-powered.
