Precision PID Temperature Controller
Introduction
Thank you for shopping the Auber WS series temperature controller. We sincerely appreciate
your decision and trust that our controller will meet your expectations in both the quality of the
result and the value of the product. While we are delighted that you may be anxious to operate
the controller, please still spend a few minutes reading through this manual because this will
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
use, the process involves high temperature and high wattage appliances and your safety is
paramount.
•
This controller is designed only to be used with limited-power device and paring thermal
cutoff protection such as a thermostat or thermal.
•
Do not place any objects on the top of controller surface because that may prevent
venting excess heat during its operation.
•
The controller can handle a maximum current up to 15 Ampere. For 120 VAC in US or
Canada, this limits the heater power to 1800 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 you system need take longer
time to warm up, please read Appendix 1 "Managing the heat generated by the
controller"

Using it to control a not recommended device can be dangerous and even 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 usage. - Page 3 Operating Instructions 1. Controller Figure 1. Front Panel. The front panel of the controller is shown in Figure 1. The function of each item is described below: (1) Parameter Window (LED) - For displaying temperature values and controller's system parameters. (2) Output status indicator - In normal mode, this LED indicates the heater status.

(7) Alarm indicator - Lit when the alarm is on. (8) Timer status indicator – Lit when Time key is pressed. (9) Editing indicator – A dot at the lower right corner. When the dot flashing, the value is editable; pressing the “+” or “-“ key to change the value. The layout of the controller back panel is shown in Figure 2. - Page 5 A schematic wiring diagram of the controller and the device to be controlled is shown in Figure 3. The connection of the controller with the device and the sensor should be done with the following steps: • Plug the sensor into the sensor port on the back of the controller. •...

Each recipe file can have up to 6 steps (C-1 to C-6). For convenience, we have pre-named these 8 pieces of recipe files as B1 (beef), B2, C1 (chicken), C2, F1 (fish), F2, P1 (pork), and P2.

Even if the controller is powered off and turned on again, it will resume working in this mode. - Page 18 Figure 13. Single-step mode flow chart. In single-step mode, the save and recall function (Section 7) 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.

To store current program back to recipe b2, long press SET, set LoCK=2, choose b2, press set to confirm and exit. Now your current program is stored as recipe b2. Recall your recipe to current program (Single-step Mode) Before you input your set temperature, check the PrG = off (accessed by LoCK code “3”). Long press SET, set LoCK=1, choose b2, press set to confirm and exit. -
