CAL Controls 3300 - Autotune Setpoint and Reminders; Tune at Setpoint Program Operation; Starting and Exiting Tune at Setpoint

Autotune
The TUNE AT SETPOINT program will now start. The
controller will alternately display TUNE and the
process temperature.
Note: During tuning the main setpoint (SP1) LED will flash.
When the TUNE AT SETPOINT program is complete the
alternating display stops and the process temperature is
displayed. The PID values are entered automatically. The
process temperature will rise to setpoint and control should
be stable. If not, this may be because optimum cycle time
is not automatically implemented. To set the cycle time see
PROPORTIONAL CYCLE-TIME.
