Sorry before i startbut from your description i think you mean
will the data transfer if you swap the controler between units then no the controller simply programes the indoor pcb.

Field settings 10/11/12/13-?-?? will programme all indoors connected to the controller by P1P2 wiring but will always indicates factory settings.

Field settings 20/21/22/23-?-?? are used for individual unit programming and indicates actual programmed settings.

Thanks for quick reply .Individual unit A ,I made changes in field setting & replace the remote controller (A1) with another same model remote controller which is factory set (B1).Can it (B1)shows the existing field setting of unit "A" In mode no 20/21/22/23/24/25 if not how to identify the second code number

the remote controller will not store the field settings. if you program a field setting then this is transferred to the indoor printed circuit board and not the wall controller.
Swapping the controllers between the two units will not have any effect on the field settings..
