ac jr temp and firmware update question

[flapjack1439]

If the temp adjustment on my ac jr is at zero, how accurate is the temp reading?

How do I find my firmware version and why should or shouldn't I update it?

The typical jr temperature cal offset is -1.0. The version of the firmware is found by doing a selftest. If you want the new features of later versions of firmware then you should upgrade. Version 3.2 adds, multiple feed cycles, and power failure statements. Version 3.3 adds support for AquaSurf.
