My installer never installed the original Mitsubishi heatpump controller for my ducted unit, since I have airtouch. I've given up with them, so will do it myself.
I purchased my own PAR-40MAA controller and I'm lost how to connect it to my PEAD 50 unit. The manuals are a bit confusing. Supposedly I need to connect it to the CN90 connector on the motherboard, but that's a 9-pin header connector, where the controller is just 2-core 22AWG wire...I must be missing something.
Anyone have any insight?
