29EcoBreeze System Operation and Maintenance

Building management system (BMS)

The Modbus interface allows the EcoBreeze to communicate with a BMS.

The Modbus connection is available in two locations on the Modbus hub of the Frame

controller:

• RJ-45 In port

• 3-wire on terminal block

See the EcoBreeze Frame Installation Manual for more information.

Configure Modbus. If you are using a building management system with EcoBreeze, set the

following values:

OTE: The EcoBreeze requires two TargetIDs. The second TargetID is automatically assigned

to one greater than the value entered. When polling the EcoBreeze, always use the TargetID

entered. Do not assign TargetID + 1 to any other device.

• Target ID: Each Modbus device must have a unique target identification number. Enter a

unique number from 1 to 247.

• Baud rate: Select from 1200, 2400, 4800, 9600, 19200

• Parity: Select from None, Even, Odd
