Overview
For proper data transfer to occur between the Building Management System (BMS) and the Flōi-Controller 2.0, the BACnet
communication connection must be properly configured. If the two controllers are not communicating and if the BMS
Communication Status displays ‘Offline’ in the BMS Status screen of the i-Controller, verify the following information.
CAUTION: Before connection, ensure there is no earth ground on the wires used for the RS485 connection.
Do not ground any of the wires connected to the RS485 terminal blocks inside the unit. Doing so will result in damage to
the i-Controller hardware.

Verify the i-Controller protocol, address, and baud rate.
Figure 1. i-Controller BMS Status screen
The “BMS Status” screen displays the current Flōi-Controller BMS protocol, BACnet address, baud rate and the status of
the connection to the BMS. If the Flōi-Controller is connected, the BMS status will display “Online”. The BMS status will
