Modbus address and communication parameters are set in Belimo actuators using
the Servicetool ZTH-EU programming unit from Belimo. The Modbus communication
protocol is 38.4 kBaud, 1 start bit, 8 data bits, 2 stop bits and no parity (see example
of ZTH-EU menu settings for VAV actuators in fig. 22). Instructions for setting Modbus
addresses in Belimo actuators can be found at www.belimo.eu.
LED indications "D" (see figs 3 and 15)
OJ GreenZone™ Module M is equipped with five LEDs, which indicate the status of the
Modbus actuators (see table 2).

NOTE!
• A flashing LED indicates that the actuator is correctly connected and addressed.
• An inactive LED indicates that the actuator is not installed, not connected correctly or
not addressed correctly on the actuator itself.
• LEDs 4 and 5 flashing simultaneously indicates that the actuator on the combination
valve/6 way valve is connected correctly and that Modbus communication is OK.
