Hi, I have a Fujitsu inverter heat pump. The numbers are AOT12LFBC & AST12LSBCW.
It's a pre-owned unit and I'm currently fitting it to my house.
My query is with the wiring connections/terminals on the outside unit. These are marked N, L & 3. Also a screw for earth. There's a four core wire running to it.
My first thought is: N for neutral, L for live & 3 for signal? Can anyone confirm or correct me please.
kindest regards
