Cheers everyone,

I have two ( DMT80480T050-16WT ) on Astral pool heaters, One burned out beyond repair. I got one from china that needs to be programmed. The program is identical to the other one that is fully working. My query is. is there a way I can backup the program on the working module and then uploaded it into the new module? the module has a slot for sd cards, this is a common procedure used by the manufactory. I am not familiar with the workaround, any help will be fully appreciated. Kind regards
