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 only to be used 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 the top of controller surface which is used to vent
excess heat during its operation.
The maximum electric current this controller can handle is 15 ampere. For 120
volt AC in US and Canada, this limits the heater power to 1800 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. If the sensor is left outside, 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. It will not only overheat the controller, but also

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 high or low limit alarm of probe 1 is on, this window will flashing
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 high limit alarm of probe 2 is on, this
window will flashing 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 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
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 it lit, the smoker
generator control output is on. When it is off, the output is off.

2. Connecting and operating the controller
Install the sensor.
(Note: If you ordered wall mount sensor instead of free hanging sensor, please see the
separate instruction in the CD for its installation)
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.

3. Programming the smoking temperature profile
A total of 6 steps can be programmed for this controller. Each step contains the set
temperature (C-X) and an ending criteria setting (E-X), where “X” is the step number (e.g.
Step 4 temperature is represented by C-4 and step 4 ending criterion is represented by
E-4). The ending criterion determines how does controller finish the current step and
start the next step. There are two options for the user, t and F. Set E-X to t if you want
step X to be end by a preset time. Set E-X to “F” if you want step X to end by a preset
temperature of the internal probe.
After you set E-X to “t”, you will be asked to set t-X 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 resolution. Each 0.1 hour equals to 6
minutes.
If you set E-X to F, you will be asked to set F-X for the temperature of the internal probe.
When all of the E-X 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 C-1 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 E-1 on the left window and the ending criterion setting on the right
window. Use “+” and “-” keys to change the setting. When finished, press the SET again
to confirm the change. The left window will display t-1 or F-1 depending whether t or F is
selected for the E-1. The right window will display the setting for t-1 or F-1. 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 step for the recipe, you can program rest of the steps of E-X to t
and set t-X 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 T-6 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 you to pick the food. If you set C-3=0 and t-3=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.

The smoker generator power is controlled by parameter R1 and R2 that can be
accessed by code 166 (see section 7-1). 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 P-X. For instance, it will display P-3 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
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. Press 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 if you want to control a Bradley
Smoker. Otherwise, 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 for tuning the controller.
