Dears,
We are facing a problem with our Hitachi VRF RAS-20FS3. The inverter board (PCB3 - 17G34825A) is not working and, consequently, the compressor Nš1 (inverter) is not working as well.
However, the system has more 3 compressors (ON/OFF) that are working properly.
Therefore, I would like to know if there is a possibility of run the system without the inverter board (by making some wiring changes) and using only the 3 compressors (ON/OFF).
I have made some trials but I couldn`t let the system running with the 3 normal compressors.
I thanks in advance for any help.
Regards,
Rafael
