Building Management System

The Modbus interface allows the EcoBreeze System to communicate with a building management system (BMS).

The Modbus connection is available in two locations on the Modbus hub:

•RJ-45 In port

•3-wire on terminal block

For an RJ-45 connection, wire as follows:

Pin 4	D(A)
Pin 5	D(B)
Pin 8	Ground

For a direct 3-wire connection, connect to the corresponding contacts on the green terminal block on the side of the Modbus hub. No connection is necessary to the 0V contact.
