press the “SET” button, the controller will run the auto
-
tuning program, the “A
U
T”
indicator flickers. After auto-tuning end, the indicator stops flickering, PID parameter
value is saved automatically. In the auto-
tuning process, press the “SHIFT” button for
another 6 seconds, the controller will stop the auto-tuning program.
During the Auto-tuning process, if over temperature alarm, the buzzer does not beep,
"ALM" indicator is not lit, the heat output will be cut off; the “SET” button is invalid,
the under window always displays temperature set point value.
