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 close to your normal cooking temperature.
You should always write down your old PID parameters, before letting the
controller 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 the 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 heaters/cookers/smokers with great result.
To activate auto-tuning, set A to 1 then exit the menu (see Fig 5). The display will
start to flash alternately between A 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 when the
controller is restarted.
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 the controller decides
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 be 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 can be accessed by input code 166. Figure 4 is the flow chart
that shows how they can be changed.
