Re: city multi ymfc
Hi IM, could you please check outdoor units' SW2-1s all should be ON so that your G-50A will decide the grouping of indoor unit and remote controller.
If SW2-1s are OFF, outdoor unit will decide the grouping.
I think one of the outdoor unit's SW2-1 is OFF position (may be system 58).
Hope this help for this issue.

Re: city multi ymfc
sw2-1 is off( centralised controller) for all 8 outdoors- i checked system 51 and that picked up all indoor controllers,the g50 picked this up- with 51 and 58 connected only 51 exists on the g50, both outdoor pcbs were swapped to see if there was an issue,but still problems with 58

Re: city multi ymfc
SW 2-1 ON for (all) both outdoor units. And register again in G-50A for groups.
RC must shown on the G50A, check all the registered groups one by one.
G01 should shown 001 indoor, 101 remote controller and so on.
Check all 13 indoor units you have.

Re: city multi ymfc
As joe says the g50 wont picpk them up if it doesn't know it has to look for them.
Programme all units and initialise G50 again.
Cheers
StuTool's ? check ! Condom's ? check !
If you can't fix it , f*ck it !!!
