Why can't I change parameters such as Proportioning Band, Reset or Rate?

Is the AT (Auto Tuning) light on or flashing?  You cannot manually change parameters such as Proportioning Band, Reset & Rate if the control is in Auto Tune or PreTune mode (AT Light on or flashing).  The PID control parameters are being controlled automatically and cannot be manually adjusted.  You will need to turn off both Auto Tune and PreTune to adjust the PID parameters.   If you wish you can reactivate Auto Tune and/or PreTune after you have manually adjusted the desired parameters.
