(7) Operation when the simultaneous temperature rise parameter is calculated
with self-tuning and auto tuning
(a) 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.
