Note 2. Set alarm

The controller offers two alarms that can be set to turn on the buzzer at specific

temperatures. The first alarm is controlled by parameters AH1 and AL1. The initial

setting will turn on the buzzer at 250°F and off when temperature drops below 249°F.

The second alarm is controlled by parameters AH2 and AL2. The initial setting of the

second alarm is deactivated. It can be set as low alarm to send warning when

charcoal is low.

AH1 and AH2 are the temperatures to turn buzzer on; AL1 and AL2 are the

temperatures to turn buzzer off. When AH1(2) >AL1(2), the alarm is set for absolute

high alarm as shown in Figure 4 below. When AH1(2) <AL1(2), the alarm is set for

absolute low alarm as shown in Figure 5 below. When AH1(2)=AL1(2), the alarm is

deactivated.

Example, if AH1=250, AL1=249, when the temperature goes up to 250°F, the buzzer

will be on; when the temperature drops down to 249°F, the buzzer will be off. If

AH2=180, AL2=185, when the temperature drops down to 180°F, the buzzer will be

on; when the temperature goes up to 185°F, the buzzer will be off.

User can press the shift key (>) to temporarily mute the buzzer sound. The alarm will

buzz again if the alarm set temperature is reached again. To permanently deactivate

the alarm, set AH1=AL1 or AH2=AL2. Please see flow chart in Figure 3 on how to set

the value.

5.2 PID parameter setting (accessed by code 0036)

The values of P, I and D parameters are critical for good response time, accuracy and

stability of the system. The values of the PID parameters have been optimized for

charcoal grill application. User should not change it unless the result is not satisfactory.

In that case, you can use the Auto-Tune function to automatically determine these

parameters. If auto-tuning result is not satisfactory, you can manually fine-tune the PID

constants for improved performance.

Setting PID parameters is similar to the setting of the Temperature and Alarm

Parameter as shown in the flow chart of Figure 3. The difference is that these

parameters are accessed by enter code 0036 instead of 0001.

Note 3. Proportional Constant (P): When P increases, the system is more stable.

When P decreases, the system is less stable. If the P is too small, the system would

be oscillatory or even non-convergent.

Note 4. Integral time (I): Brings the system up to the set value by adding a constant to

the output that is proportional to how far the process value (PV) is from the set value

(SV) and how long it has been there. When I decreases, the response speed is faster

but the system is less stable. When I increases, the respond speed is slower, but the

system is more stable. When I is 0, then it turns to be PD control.

Note 5. Derivative time (d): Responds to the rate of PV change, so that the controller

can compensate in advance before |SV-PV| gets too big. A larger number increases

it's action. Setting d-value too small or too large would decrease system stability,

cause oscillation or even non-convergence.

Note 6. Damp constant (SouF): The parameter is controlled by the artificial

intelligence of the controller. This constant helps the PID control quality. When its

value is too high, the system will be over damped. When its value its too low, the

system may overshoot.

Note 7. Cycle rate (ot): It is the time period that the controller uses to calculate its

output. The initial value is set to 15 seconds for charcoal smoker control. Short time

causes the fan to pulse at higher frequency. Longer time may reduce the quality of

control

Note 8. Digital Filter (Filt): can be set as 0, 1, 2, 3. Filt=0, filter diabled; Filt=3, strongest

filtering effect. Stronger filtering increases the stability of readout display, but causes

more delay in the response to changes in temperature.

Note 9. The value of outy determines the control mode: When it is set to,

2: PID control mode.

3: On/off control mode.

6: Limit control mode.

Setting value for 0, 1, 4, 5 should not be used for this controller.

The new outy setting will not take effect if the outy is changed until the controller is

restarted .

Note 10. Hy is only used when controller is in on/off or limit control mode. It sets the

hysteresis band for the controller.

Note 11. The auto-tune offset will shift the SV value down by the Atdu value during the

auto tune process. It will prevent the system from damage due to overheating during

auto-tuning.

Note 12. Calibration offset, PSb is used to set an input offset to compensate

the error produced by the sensor. For example, if the meter displays 5 ºC

when probe is in ice/water mixture, setting PSb=-5, will make the controller

display 0 ºC. To set negative value, shift to the very left digit, press down key until it

shows "-".

Note 13. Rd is for system function selection, 1 for cooling, 0 for heating.
