Autotuning
If a tune error condition occurs, the upper display will toggle
between and a numeric error code for three seconds before
the tune process terminates. The controller will then automatically
go into Standby mode when a tuning error occurs. Possible error
codes are:
02 = No PID Device Configured
03 = Incorrect Output Action
05 = Insufficient Setpoint-Process Value Deviation
08 = Invalid Tune Results
09 = Tune Timeout

Note: Keep in mind that the setpoint value must be at least 1%
of span above or below the initial setpoint, and that the process
value must be stable prior to initiating the tune.
