Introduction
Thank you for purchasing the Auber WS series temperature controller. We sincerely
appreciate your decision and trust that our machine will meet your expectations in both
the quality of the result and the value of our product. While we are delighted that you may
be anxious to operate the controller for your project, a few minutes of your time reading
through this manual will only serve to enhance your experience in the months and years
ahead. In particular, we urge you to read through the safety warnings below. Although
this plug-and-play controller is very easy to operate, the process involves high
temperature and high wattage appliances, and your safety is paramount.
SAFETY WARNINGS
This controller is designed to be used only with devices that have limited power
and their own thermal cut off protection, such as a thermostat or thermal fuse in
case of controller failure.
Do not place any objects on top of the controller surface as it is used to vent
excess heat during its operation.
The maximum electric current this controller can handle is 12 ampere. For 120
volt AC in US and Canada, this limits the heater power to 1440 watts.
Always place the sensor in the controlled subject when the controller is on. Before
turning on the controller, please make sure the sensor is placed inside the
container to be controlled. Leaving the sensor outside of the solution will form an
open loop operation, and the controller will assume the temperature is low even if
the controlled subject is already very hot. The controller will provide full power to
the heater which will not only overheat the controller, but also damage your
*Patent pending

2
appliance or even cause a fire.
This controller is designed to control the devices recommended by Auber
Instruments only. Using it to control a non-recommended device can be
dangerous and cause fire. Auber Instruments is not liable for damages caused by
misuse of the controller. If you are not sure the controller can be used, please
contact Auber Instruments before use.
If an abnormal display or noise is observed, turn the controller off, unplug the
power cord and contact the manufacturer before using it again.
Clean the controller only when it is cool and unplugged.
Do not allow children to operate the controller.
Operating Instructions
1.Description of the controller.
Figure 1. Front Panel
1) TEMP1, Left window - During normal operation, it displays the temperature values
of probe 1. When the high or low limit alarm of probe 1 is on, this window will flash
between the alarm type (AH1or AL1) and the temperature. In the parameter setting
mode, it displays the controller's system parameters.
2) TEMP2/TIME, Right window -During normal operation, it displays the
temperature value of probe 2 (food internal temperature probe) or the time passed
since the controller was powered up. When the high limit alarm of probe 2 is on,
this window will flash between AH2 and the temperature. In the parameter setting
mode, it displays the value of the parameter.
3) Output status indicator - This LED indicates the output status that should be
synchronized with the heater. When it is on (lit), the heater is powered. When it is
off, the heater power is off. When it is flashing, it means the heater is on and off

3
intermittently to reduce the power output. It should be synchronized with the power
light on the cooking device.
4) Smoker generator control output status indicator. When lit, the smoker
generator control output is on. When off, the output is off.
5) Timer status indicator - When lit, right window shows the time passed since
power up. When it is off, right window shows the current temperature detected by
the probe 2.
6) SET Key - For showing current temperature settings, entering parameters setting
mode and confirming various actions taken.
7) “-” Key - To decrement displayed values when controller is in the parameter
setting mode. During normal operation, press it to cancel the alarm.
8) “+” Key - To increment displayed values when controller is in the parameter setting
mode. During normal operation, pressing it will change the left window from
temperature to display which step the program is at.

The controller is supplied with two probes. The one with the short tip is for measuring the
cabinet temperature. We name it probe 1. It needs to be plugged to the top sensor jack
at the back of the controller. The long probe with a bend at the end is for the meat
internal temperature measurement. It needs to be plugged to the bottom sensor jack at
the back of the controller. The tips of the probes are dropped into the damper hole. Place
a piece of tape on the top of the smoker tower to hold them in place. The tip of probe 1
should be placed close to the food but high enough so that it does not touch the food.
(See Figure 3). The tip of probe 2 is to be inserted into the meat.
Figure 3. Sensor position. Left, the sensor should be placed close to the food but high
enough so that it does not touch the food. Right, hold the sensor in place by a piece of
tape.
For the “Original” and Stainless Steel Bradley smoker, the Temperature Heat Control
Switch on the smoker tower should be slid to the Hi position (Most right).
There are several ways to power up the controller and Bradley Smoker.
1) Connection for Bradley Original Smoker, with control of the smoker generator.
a) Connecting the controller to the power outlet, you should use the power cord that
came with the Bradley Smoker for connecting the smoker generator to the power outlet.
b) Connecting the controller to the smoker generator. You should use the power cord that
originally was used for connection between the smoker generator and smoker tower.

2) Connection for Bradley Original Smoker, without controlling the smoker
generator.
If you don’t need to control the smoker generator, connect the controller to the smoke
generator with the cable that used to be connected between the generator and tower.
Then, connect the controller heat output to the smoke tower with the cable supplied with
the controller.
Figure 8. Connection without controlling the smoker generator
3) Connection for Bradley Digital Smoker.
For the Bradley Digital Smoker, both controller and smoker generator should be
connected directly to the wall outlet. Connect the controller output with the smoker tower.

3. Programming the smoking temperature profile.
A total of 6 steps can be programmed with this controller. Each step contains the set
temperature (C0X) and an ending criteria setting (E0X), where “X” is the step number
(e.g. Step 4 temperature is represented by C04 and step 4 ending criterion is
represented by E04). The ending criterion determines how the controller finishes the
current step and starts the next step. There are two options for the user, t and F. Set E0X
to t if you want step X to be end by a preset time. Set E0X to “F” if you want step X to end
by a preset temperature of the internal probe.
If you set E0X to “t”, you will be asked to set t0X for the time. Time is defined as the
duration between the last step and the next step. Please make sure the time is long
enough for the heater to heat up the smoker. If the time is set too short, the temperature
may not be able to reach the current step temperature setting, before it jumps to the next
step. The time unit is in hours with 0.1 hour (6 minute) resolution.
If you set E0X to F, you will be asked to set F0X for the temperature of the internal probe.
If all of the E0X are set to t, the controller can operate with only the probe 1 plugged in.
To program the temperature profile, press SET key once. The display will show C01 at
the left window and temperature setting on the right window for step 1. Use “+” and “-”
keys to change the setting. When finished, press the SET again to confirm the change.
The display will show E01 on the left window and the ending criterion setting on the right
window. Use “+” and “-” keys to change the settings. When finished, press the SET again
to confirm the change. The left window will display t01 or F01 depending whether t or F is
selected for the E01. The right window will display the setting for t01 or F01. Use “+” and
“-” keys to change the setting. When finished, press the SET again to confirm the change.

The display will go the step 2 setting. It will repeat in the same way as the step 1. After
you program enough steps for your recipe, you can program the rest of the steps of E0X
to t and set t0X to zero.
The temperature setting will not be changed if SET is not pressed (confirmed). After
programming the necessary steps for cooking, you can finish programming by pressing
the SET continuously until it passed T06 and display the current temperature. You can
also leave the controller alone. The display will return to the normal display mode if no
key is pressed within 15 seconds.
The initial program setting for the controller is listed in
Table 1. This program will control the temperature of the cabinet at 120 °F for 2 hours.
Then, change the temperature to 190 °F. It will stay at 190 °F until internal temperature of
the meat reaches 160 °F. Then, the controller will drop the temperature to 130 °F for 30
hours, waiting for you to pick up the food. If you set C03=0 and t03=0, when meat
internal temperature reaches 160 °F, the controller will shut off the heater, flashing END
on both windows, and turn on the beeping alarm to notify you that cooking is finished.
Table 1. Initial program setting
Step # Temp (F) Step # F or T Step # value
C01 120 E01 t t01 2.0
C02 190 E02 F F02 160
C03 130 E03 t t03 30.0
C04 0 E04 t t04 0.0
C05 0 E05 t t05 0.0
C06 0 E06 t t06 0.0
The smoker generator power is controlled by parameters R1 and R2 which can be
accessed by code 166 (see section 7). The generator can be turned on for two steps. R1
is for the first step. R2 is for the second step. e.g. To turn on the smoker generator at step
1 and 3, set R1=1 and R2=3. If you only want to use one step, set either R1 or R2 to 0,
and set the other one to the step you want to turn on the smoker generator. The initial
setting for the controller is to turn on the generator at step 1 only.
4. Check the current step and display the time
To check which step the program is at during cooking, press the “+” Key (8) once. The
left window will show the current step in the form of P0X on. e.g. It will display P03 if the
controller is at step 3. The display will return to the temperature display automatically
after 8 seconds. To check how long the controller has been running since powered up,
press the Time key (9) once. The Timer status indicator will light. The right window will

10
show the actual time passed since the controller was last powered up. Please note that
this is the total time, not the time that has passed in the current step. Pressing the Time
key again will switch the display to the internal temperature.
5. Tuning the controller
This controller contains two sets of system parameters that can be changed for different
applications. This controller is shipped with the system parameters set for the Bradley
Smoker. The user should not change these parameters. However, if you feel that
performance is not ideal, you can try to manually tune the system or run the auto-tune
again. For detailed information on how to tune the controller, please read the section 7
and 8 of the main manual.
6. Important consideration for better control results.
The following is a list of things that could affect the results of temperature control.
a) The smoker and controller location. The smoker should not be placed directly in the
sun. Direct sun light can heat the smoker to above 140 °F in the summer time, making
controlling the temperature at 140 °F impossible. This is especially the problem for the
Bradley Original Smoker because of its black color. The controller should be placed
away from direct sun light also. Although the controller uses a high intensity LED display,
it will still be difficult to read when sun light is directly shined to its surface. Users should
also avoid exposing the controller to water and rain, which could damage the controller.
b) Low temperature control. The control result for temperatures below 125 °F will not be
as accurate as for higher temperatures when the smoker generator is on. This is
because there are two heaters in the smoker tower. One is the smoker heater controlled
by the PID controller. The other is the heater from the generator that is not controlled.
Our test shows that the heater in the generator itself can raise the temperature of the
smoker tower by 60 °F (2 hours, in the shade with damper open). That means when the
ambient temperature is at 70 °F, the smoker can be heat up to 130 °F in 2 hours by the
heater of the generator (without using the heater in the smoker).
c) Damper position. Keeping the damper open will result in better temperature stability
because more heat loss is created. This is important when the temperature is set below
140 °F. When the damper is closed, the temperature will take longer time to drop if it is
overshot during initial heat up. At higher temperatures, closing the damper will not affect
the performance much because the heat loss from the walls of the tower is increased.
Closing the damper at high temperature will keep the moisture of the food.
d) Temperature uniformity of the smoker tower. Our test shows that when all the shelves
were empty, the temperature inside the smoker tower was fairly uniform except the back
