Had a burn marks on both the main pcb and power pcb, as well as the inverter pcb. Ever since replacing the boards and attempting to auto address, the outdoor unit cannot find any indoor units or Hr boxes. Any reason why?
When he says "this only applies to heat recovery systems" what is he referring to? The entire process of using shielded wires, or landing the ground terminals to indoor units?
Your question is highly appreciated. To ensure proper installation, it is crucial for the installer to use the wire explicitly mentioned in the instructional video, irrespective of the system configuration. It is important to note that the section in the video where our host demonstrates the wiring process for the heat recovery box is solely applicable to systems equipped with heat recovery functionality. If your system does not include a heat recovery box, you may disregard that specific segment of the video.
In this situation, we need to connect the first two terminals on each condenser. Make sure to use an 18-2 shielded, stranded wire for this connection. Also, remember to ground the wire on the main condenser separately from the communication setup for the indoor units.
Do have to this if I don’t use the branch box?

What if there are two condensing units master and slave
