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. 

 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 use it with a cook top or hot plate. 

  Do not place any objects on the top of controller surface which is used to vent 

excess heat during its operation. 

  When open the cover of a rice cooker or slow cook that has been running for 

extended period of time, the cover will carry a lot of condensation that can drip to 
everywhere. Avoid drip the water over the controller.   

  The maximum electric current this controller can handle is 15 ampere. For 120 

volt ac in US and Canada, this limits the heater power to1800 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 
design for kitchen applications, the controller has a limited ability to dissipate the
