Programmable Precision PID Temperature Controller
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 would 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 controller surface which is used to vent
excess heat during its operation.
 When opening the cover of a rice cooker or slow cooker that has been running for
extended period of time, the cover will carry a lot of condensation that can drip
everywhere. Avoid dripping the water over the controller.
 The maximum electric current this controller can handle is 12 amperes. For 120
volt AC in US and Canada, this limits the heater power to1440 watts. In addition, if
the heater power is more than 1400 watts, the volume of the pot is also limited to
less than 10 gallons (or 38 liters). Due to its compact size and the splash proof

    Weight: 2.2 lb (1 kg) without power cord. Note, for international orders (except Canada), the input power cord is not included due to its weight and different plug requirement. The controller has standard IEC 320 C13/14 socket. Users can use a power cord that meets the local standard to power it. Please make sure the wire gauge can carry the maximum current required.

Based on the response time of the whole cooking system, the controller will calculate and set the PID parameters for your cooker. Figure 4 Before using the auto-tune function, you must set the cooking equipment up in the exact configuration it will be used.
  • Page 10 If you tried auto-tune and the parameters we provide but feel the performance is not ideal, the following sections discusses the definition of these parameters and how to change them.  LCK. Parameter lock. This function is used to prevent user from changing the critical parameters on accident.

Mark the outside of your package “ATTENTION CUSTOMER SERVICE”. We are constantly striving to improve our products and therefore the specifications contained herein are subject to change without notice.
  • Page 16 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 17 In addition to these solutions, the following information will also help you 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.
  • Page 18 Appendix 2 Controlling the Temperature of Bradley Smoker 1) Connecting the controller There are two ways to power up the controller and smoker. a) Using two power cords and a power strip. This set up is good for the “Original”, Stainless Steel, and Digital Bradley Smoker.
  • Page 19 Fig 4. Power connection of the controller and smoker. The generator is connected to the power strip by the power cord from Bradley (green arrows). The input of the controller is connected to the female receptacle on the generator by the power jumper cord provided by the Bradley (blue arrows).
  • Page 20 Fig 5. 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 with 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).
  • Page 21 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 a longer time to drop if it is overshot during initial heat up.
