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 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 15 ampere. For 120 volt AC
in US and Canada, this limits the heater power to1800 watts. Due to its compact size
and the splash proof design for kitchen applications, the controller has a limited ability
to dissipate the heat generated by the internal solid state relay during the initial heat
up. The initial full power heat up process cannot be more than 90 minutes. If the
system needs a longer time to warm up, please read Appendix 1 “Managing the heat
generated by the controller”
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 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. It will not only overheat
the controller, but also damage your appliance, and possibly even cause a fire. If the
