FBA-A Ducted system compatibility

[rafavaleros]

Hello there!

First of all, congrats to RevK and the rest of developers for the project, it is really amazing that you can manage to design a solution that is much better than the official product and maintain it just for the sake of it. Really appreciate it!

I have recently bought two FBA-A ducted units and was trying to see if this solution works for me. I have searched a lot about wiring, but it seems my units dont have an X50 or S21 ports, so I wanted to share a picture of the wiring diagram to see if anyone has used a similar unit succesfully, or if it could be done

From the picture, I guess that if possible, it should be done from the X33A connector, maybe also using X35A for power. Any ideas?
Also, as the unit is new, I wanted to ask you about potential damage to the machine. I am confident that I can connect it safely, but I am worried that it could damage the main board due to malfunction or something similar and bombard it with info until it broke. Could this happen?

Thanks a lot for the help!!

X35 is just for power. Some units can take an S21 adapter board Daikin do, no idea if this is one.

I'll try to see where the BRP069C81 is connected in these machines, as I know that one works for them. Thanks!!
