CTC GSi Heat pump modbus connection

That google sheet doc is awesome and it annoys me that I stumbled across this after converting those PDF to excel myself…
But I just wanted to give you a heads up that the linked document you referenced is no longer available on CTCs homepage, but they have a new version instead (to include newer model I guess?), that version also includes a new column “Name” for the functions.

Thank you for this information. Sadly it looks like that this document does not include more registers, or does it?
