window and send an audio beeping sound. Turning off the power and on again will reset
the timer.
b) Use it as a clock. Instead of using the timer function, many users just use it as a clock
to find how long the food has been cooked. To use it as a clock, set the time longer than
you need to use, or, just set the timer at 9999 minutes. During the operation, press the
"time" button once will change the display from temperature of the pot to the time that
has elapsed since powered up. Pressing the "time" button again will change the display
3.4 Tuning the controller
This controller is shipped with parameters set for commercial rice cookers. You can try to
use these settings for other cooking device also because they are suitable for a typical
slow response and balanced system. 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
obtain from tuning the system manually. If your cooker is not listed in the Table 1 of our
pre-selected cookers, or the PID parameters we provided are not working for your liking,
you can use the auto-tuning function to let the controller to determine the PID
parameters automatically. You can also manually tune the PID parameter if you are
familiar with PID control technology. To activate the auto-tuning processes or change the
P, I and D parameters, please see the next section and Figure 7.

Please note that the P value in table is in Fahrenheit unit. If the controller is using
Celsius unit, divide the P value by 1.8. If you switch from Fahrenheit display to
Celsius, the controller will automatically convert all the settings.
