Programmable PID Temperature Controller with Dual Probe
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.
• 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 the controller surface as it is used to vent
excess heat during its operation.
• The maximum electric current this controller can handle is 13 ampere. For 120
volt AC in US and Canada, this limits the heater power to 1450 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

    • 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.

(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.

  • Page 9 3. Programming the smoking temperature profile A total of 6 steps can be programmed with 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).
  • Page 10 hours, waiting for you to pick up 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. Table 1.
  • Page 11 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.

  • Page 18 8. Auto-Tune This section can be ignored if you are using the controller to control the Bradley Smoker because the controller is already set for it. The controller's most powerful feature is its ability to regulate virtually any cooker with stable temperature control.
  • Page 19 Before using the auto-tune function, you must set the cooking equipment up in the exact configuration it will be used. For example, to tune a rice cooker, place the sensor in the pot filled with water at room temperature and plug the cooker into the controller. If the cooker has its own thermostat or power control, turn both as high as they’ll go.

If you press “+” (or “-” key) repeatedly, you will see “End”, “b1”, “b2”, “C1”, “C2”, “F1”, “F2”, “P1”, “P2” one by one. Press the SET key again to store your current program under the selected recipe name.

  • Page 22 Figure 12. Single-step mode flow chart. In single-step mode, the save and recall function (Section 9) can still work. But the change can only be applied to C-1, i.e., you can only store your current set temperature to the C-1 in a selected recipe, or recall the C-1 temperature from a selected recipe to the current set temperature.
  • Page 23 Before you input your set temperature, check the PrG = off (accessed by LCK code “3”). Press SET key once, and then set C-1=150, press set again to confirm and exit. The controller will go back to the normal operating mode and start running on this single-step program.

  • Page 27 Appendix 1 Managing the heat generated by the controller The heat dissipation of the controller is directly related to the electric current drawing power of the heater. If your cooker consumes less than 10 ampere of current or your pot is less than 5 gal (19 liters), you do not need to worry about the heat generated by the controller.
  • Page 28 In addition to these solutions, following information will also help you to manage the heat. Place the controller in the right place. The SSR of Auber WS series controller is mounted in the bottom of chassis. The chassis is made of 3 mm thick aluminum for good heat dissipation.
