Operation of when the simultaneous temperature rise parameter is calculated
■When the simultaneous temperature rise AT is started before the simultaneous temperature
rise parameter is calculated with self-tuning
The simultaneous temperature rise parameter is not calculated neither with self-tuning nor auto tuning. PID constants are
changed.
