disable the AL (Pit) alarm, you can set it to a small number, such as 0° F
(default).

Note 3. AH (Food): This is the high temperature alarm for the food probe
(Probe 2). When food probe reading is higher than AH (Food) value, the
buzzer on the controller will go off and the LCD display will flash between the
normal display and the alarm display showing in Figure 12. The alarm has 1°
hysteresis. The user can mute the buzzer by pressing either the Up key or
the Down key. For example, if AH (Food) is set to 130° F, the buzzer will go
off when Probe 2 reads 131° F, and the buzzer will stop when Probe 2 reads
129° F or lower. To disable AH (Food) alarm, you can set it to a large
number, such as 999° F.
When smoking multiple pieces of meat of different sizes or thickness, you
can put the probe in the thinnest piece first. Set the AH (Food) alarm to the
temperature when meat is ready. It will let you know when it is done. Then,
you can move the probe to the second thinnest pieces and so on. To use this
feature, you can set the ending criterion to time. If you prefer to set the
ending criterion to food temperature, then the Food Temp should be set to
higher than the AH (Food).

Note 4. P: Proportional Constant. The unit is 1 degree. This parameter control
the output of the controller based on the difference between the measured and
set temperature. Larger the P number means the weaker the action (lower
gain). If P = 7, the proportional band is 7 degree. When the sensor
temperature is 7 degrees below the proportional band (10 degrees below the
setting), the controller will have 100% output. When the temperature is 5
degree below the set point, the output is 71%. When the temperature is equal
to the setting, the controller will have 0% output (assuming integral and
derivative functions are turned off). This constant also affects both integral and
derivative action. Smaller P values will make the both integral and derivative
action stronger. Please note the value of the P is temperature unit sensitive. If
you found an optimized P value when operating the controller in Fahrenheit,
you need to divide the P by 1.8 when changing the temperature unit to
Celsius.
Note 5. I: Integral Time. The unit is in seconds. This parameter controls the
output of controller based on the difference between the measured and set
temperature integrated with time. For example, if I = 1000, it means if the
temperature difference between the pit temperature and set temperature stays
constant, the output will be doubled after 1000 seconds. Integral action is
used to eliminate temperature offset. Larger number means slower action.
Note 6. 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 its rate of change. The larger the number is, the stronger the
2019.07
action will be. For example, when the door of oven is opened, the temperature
will drop at 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.
Note 7. T: Control Cycle Time. The unit is second. This unit determines how
long for the controller to calculate each action. It is only meaningful in the
PWM mode. e.g. if T is set to 15 seconds, when controller decide the output
should be 10%, it will turn on the heater 1.5 second for every 15 seconds. This
parameter is set to 15 seconds by default.
Note 8. OL Switch: Open-Lid Detection Switch. This parameter works as an
on/off switch to enable or disable the Open-Lid Detection function. When OL
Switch is set to "on", the Open-Lid Detection function is enabled; otherwise,
disabled.
When the lid or dome of a smoker is opened during smoking, the pit
temperature will drop quickly. The derivative function (d) of the PID controller
will force the blower to run, probably at the maximum speed, in order to stop
the trend of temperature-dropping. This action would blow up ashes, blow the
flame stronger, and cause a big temperature overshot after the lid is closed.
The open-lid detection function is designed to prevent these problems.
When the smoker's lid or dome is opened, this function will detect the sudden
temperature drop and stops the blower. After the lid is closed and the pit
temperature is recovered by the residual heat stored in the smoker, the blower
will resume running. However, after 7 minutes, if the temperature still hasn't
been recovered yet, the controller will resume sending its output to the blower.
This open-lid detection function is inactive when you starting the fire at the
beginning. It will be activated after the pit temperature less than 5 degree
lower than the set temperature. Sometimes the open-lid detection might be
triggered accidently by a temperature drop not related to lid-opening during
smoking. In that case, you can cancel this activation by pressing the
Time/Back key on the controller, or tap the "X" (Cancel) symbol appeared near
the "Open-Lid Detection" on the SYL-2615 device info page from the
AuberSmart app. In situations where the open-lid detection is activated by
actual lid-opening action, we recommend you not to cancel this function to
avoid getting a pit temperature overshot. The controller can take care of this
issue and minimize the disturbance. But if you are cooking at a higher
temperature range (> 300° F), the pit temperature many not be able to recover
by itself. In this case, cancel the activation.
If you want to manually pause the fan output temporarily, you can press and
hold Up key for 3s. To resume the fan output, press Up key again
momentarily. (firmware 1.9 or newer).
Note 9. Save & Recall: This controller allows the user to save and recall up to
6 sets of the P, I, D, and Control Mode settings. The user can tune the settings
for cooking at different conditions (e.g., different smokers/grills, different
ambient temperature, or cooking temperature) and save them for future use.
Three sets of settings for 18.5'' Big Green Egg, 22.5" Weber Smoky Mountain,
and 18.5" Weber Smoky Mountain has been pre-saved on the controller as
"BGE", "WSM22", and "WSM18" respectively. Another 3 sets of settings
named as "4", "5", and "6" are available for custom tuned parameter settings.
The names for those sets cannot be changed at this moment. Please see
Table 3 for the name and the values of each group of settings.
