INFO:
The pre-installed MODBUS Address is the last 2 numbers of the serial
number.
For example the EFOY Pro with serial number 123456-1234-56789 has
the MODBUS address 89. In the case where the serial number ends with
00 the address 100 is set.
The MODBUS address of each EFOY Pro fuel cell can be changed via the
Operating panel OP2 or with the MODBUS command:
CAUTION!
Wrong set addresses can cause conflicts within the communication net-

Make sure that every MODBUS address in an RS-485 network is only
given once. If one address is given to several components the network
can be disturbed.
