For historical reasons, each of the UI410 temperatures (external Pt1000 sensor, register 12, and internal ADT75, register 13) has a different format.
The conversion is as follows:
external: (read value / 100) - 50
- eg 6230 means 12.3 Â ° C
internal: read value / 10
- eg 295 means 29.5 Â ° C
You need to be careful about that.
