ERROR SIGNALLING

Error Reason
- - - - Probe interrupted
uuuu The measured variable is under the probe's limits (under-range)
oooo The measured variable is over the probe's limits (over-range)
ErAt Auto-tuning not possible because the process value is higher (with "Func" =HEAt)
than [SP- |SP/2|] or lower (with "Func" =CooL) than [SP+ |SP/2|].
noAt Auto-tuning not finished within 12 hours
ErEP Possible anomaly of the EEPROM memory
