integrated with time. Integral action is used to eliminate temperature offset. A

larger number means slower action. e. g. assuming the difference between the

measured and set temperature is 2 degrees and remains unchanged, the output

will increase continuously with time until it reaches 100%. When temperature

fluctuate regularly (system oscillating), increase the integral time. Decrease it if

the controller is taking too long to eliminate the temperature offset. When I=0, the

system becomes a PD controller. For very slow response systems such as slow

cookers and large commercial rice cookers, setting I = 0 will significantly reduce

the temperature overshoot.

 d. Derivative time. The unit is in seconds. Derivative action contributes the output

power based on the rate of temperature change. Derivative action can be used to

minimize the temperature overshoot by responding to its rate of change. The

larger the number is, the faster the action will be. e.g. when the door of an oven is

opened, the temperature will drop at a very high rate. The derivative action

changes the controller output based on the rate of change rather than the net

amount of change. This will allow the controller to act sooner. It will turn the heater

to full power before the temperature drops too much

 AT, Auto Tune.

Every type of cooker has its own unique set of tuning parameters. For the

controller to heat with stability, it should have programmed with the tuning

parameters for the cooker currently being used.

When Should the Controller be Tuned?

The auto-tuning function (it's often known as self-tuning) can automatically

optimize the PID parameters for your chosen cooking system. The auto-tuning

function will heat up your cooker then let it cool down. It will repeat this heat/cool

cycle several times. Based on the response time of the whole cooking system, the

controller will calculate and set the PID parameters for your cooker.

Before using the auto-tune function, you must set the cooking equipment up in the

exact configuration it will be used. For example, to tune a rice cooker, place the

sensor in the room temperature pot filled with water and plug the cooker into the
