controller. If the cooker has its own thermostat or power control, turn both as high

as they'll go. Set the controller to the appropriate power level (see next Section).

Turn the controller and cooker on, and then enter the desired set point

temperature closed to your normal cooking temperature.

You should always write down your old PID parameters, before letting the

controller to perform auto-tuning. This way if something goes wrong, you can

always go back to your old PID parameters. The water amount in the pot should

be the same volume as you would have normally used. Basically, you must setup

your cooking system close to your actual cooking environment.

The duration of auto-tuning depends on how fast the system is responding to the

heating and cooling cycle. If the temperature of the cooker takes a long time to

drop -when heater is off- the auto-tuning could be a very long tuning process. This

is especially true with a well insulated cooker. The auto-tuning should be able to

tune most of your chosen with fairly good result.

To activate auto-tuning, set AΓ to 1 then exit the menu (see Fig 5). The display will

start to flash alternately between AΓ and the current water bath temperature,

which indicates auto-tuning is in progress. When the display stops flashing, the

auto-tuning is finished. Now, the newly calculated PID parameters are set and are

used for the system. The new parameters will store in the memory even the power

is off.

• T, cycle rate. The unit is second. This unit determines how long for the controller

to calculate each action. e.g. If T is set to 10 seconds, when controller decide the

output should be 10%, it will turn on the heater 1 second for every 10 seconds.

This parameter should set at 2 second for heating with an electric heater. When

controlling a solenoid valve or a compressor of refrigerator, the T should set to

10-20 to reduce the frequency of on/off.

To prevent changing critical parameters by accident, an access lock, LCK is used.

Special code is needed to open the lock for these parameters.

This group of parameters is accessed by input code 166. Figure 4 is the flow chart that

shows how they can be changed.
