5.1.5 Over-riding Autotune Values

After AT/PT, any Autotuned parameter may be changed to an
Option from the table. The original Autotuned value is retained in
memory.
Subsequent Autotune AT or PT replaces manual
selections with new calculated values (except Cycle
Time).

5.1.6 Autotune Hints

For Autotune error messages, see EE5 through EE7 in Section
4.1. Latched: Press
AT/PT tunes most applications satisfactorily, but if tuning fails and
error messages repeatedly occur, the application has unusual
characteristics requiring manual tuning.
Tuning with setpoint near ambient temperature: Difficult both to
control and Autotune. Use PT. If tuning fails, try using Function
.5/Option 1. Otherwise increase setpoint or tune manually.
