Dear Friends,

I've few MHI FDURA45KXE4R which uses old 3-core remote controller (X-Y-Z) but need to replace remote controllers.

14818

New remote controllers are having 2-core wire style.
So, I've tried to connect RC-EX1A X-Y to indoor X-Y but nothing happened, when connected RC-EX1A XY to indoor XZ, the remote controller shows on screen "Searching IU" but can't find anything as the data cable (Y) from indoor is not connected anywhere...

Is there any way to connect latest RC-EX1A (2 core wire) remote controller to indoor which has X-Y-Z (3 core wire) terminals? Resistors, gateways or something?

Thank You for your help and support in advance...
