Indoor or outdoor unit on Aquarea H-series

[mariavd]

Hello, I have an H-series heat pump, and I bought the small PCB from Tindie, together with the CN-CNMODE cable. Do I need to connect it to the indoor or the outdoor unit?

Thank you. I couldn’t find instructions online. Which side of the unit do I need to open?

Please don't do it by yourself, if this level of question is raised, find profesional who could install it, it's dangerous!

I have experience with electronics, I just didn’t find information online where it needs to be installed.
