i-Controller 2.0 BACnet Communication Settings
Title
Overview
For proper data transfer to occur between the Building Management System (BMS) and the Flō i-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.
