To add a terminal in the pLAN or change the settings, follow this procedure:
1 Press the UP, DOWN and ENTER buttons for at least 10 seconds.

I/O Board Adr:
3 You can choose between the different boards (1, 2, 3, 4 for the compressors and 5, 7, 9, 11 for the
electronic valve drivers) using the UP and DOWN buttons.
4 Select in correspondence of "I/O Board Adr" number 1(Board with address 1) and push ENTER.
After 2 seconds the following screen will appear:

6 If you want to add a second terminal (remote terminal), change the line "Trm2 None -" into Tmr2
17 sh". To enable the new configuration, put the pointer on "No" using the ENTER button and
change it into "Yes" using the UP and DOWN buttons and push ENTER again.
Repeat the operations from 1 to 6 for all the compressor boards. ( "I/O Board" from 1 to 4)
At the end of operations, turn off and restart the system.
It is possible that the terminal is stuck on a unit after restart. This is due to the fact that the memory of
the Drivers remains fed by the buffer battery and keeps on to contain the data of the preceding
configuration. In this case, with the system not fed, disconnect the batteries from all drivers and
therefore connect again.
