4) Checking the current step and display the time
This is done by pressing the Time Key (“6)”) once. The display will show T0X for one
second before it displays the time it has been on. e. g., it will display t03 for a second, if
the controller is in step 3 of cooking.
When “8)” is on (lit) and “7)” is flashing at the same
time, LED is in timer mode and shows the actual time passed since the controller was
last powered up. Please note that this is the total time, not the time that has passed in the
current step. Press Time key again will switch the display to the current temperature.
Both “7)” and “8)” will be off.
6) Tuning the controller
This controller is shipped with the system parameters set for the Bradley
Smoker. The user should not need to change these parameters. If you feel the
performance is not ideal, you can try to use the recommended PID parameters listed in
Table 1. These are the parameters we obtained from tuning the system manually. Fig 5
shows how to change them.
