Modbus

12.1 Modbus communication

The controller includes a Modbus slave communication protocol, type Modbus
RTU RS485.
Connection between BMS (building management system) and Micro 3000
requires two polarized wires on C+ and C-, respectively labelled 25 and 26 on
controller C Bus terminal.

The connection via shielded cable is not required but can be performed with
the terminal 24 if long wire distance or electromagnetic disturbances into the
heating room. For this, it is necessary to unscrew the front panel.

12.2 Connecting multiple Micro 3000 control boxes

Rules to respect

Max length between BMS and farer control box: 500 meters
Connection continuity (C+ and C-) has to be done directly on the controller C Bus
terminal, without using derivation boxes. Respecting this, there are two wires per
terminal, except the farer control box.
