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 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.

• The maximum electric current this controller can handle is 15 ampere. For 120 volt AC in US and Canada, this limits the heater power to 1800 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. If the sensor is left outside, 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 even cause a fire.

• This controller is designed to control the devices recommended by Auber

internal temperature measurement (Probe 2). It needs to be plugged to the bottom sensor jack at the back of the controller. The tips of the probes are dropped into the damper hole. Place a piece of tape on the top of the smoker tower to hold them in place. The tip of Probe 1 should be placed close to the food but high enough so that it

does not touch the food. (See Figure 3). The tip of Probe 2 is to be inserted into the

meat.

11/31

4.1 Set the Cooking Profile

The controller’s cooking profile can be either set to multi-step mode (default) or singlestep mode. In the multi-step mode, up to 6 steps can be programmed. Each step has its own set temperature for cabinet probe (Probe 1), and its step-ending criterion. A cooking step can either end by timer or by food internal temperature (Probe 2). In the single-step mode, the controller will try to maintain the cabinet temperature at the set value of Step 1

(“Step 1 SmkrTemp”) as long as the controller is on. To switch between single-step mode and multi-step mode, please check section 4.1.3.

4.1.1 Multi-Step Mode

A total of 6 steps can be programmed on this controller. Each program step comprises a target temperature of cabinet (shown as “SmkrTemp: XXX”) and an ending criterion setting “ X-Ending ”, where “X” is the step number. For example, “ 1-Ending ” means the ending criterion of Step 1 . The “ending criterion” is a new concept to people who never used Auber’s controllers. It determines how a cooking step is considered finished. Two options are available: time and food internal temperature (Probe 2). If you want Step X to be ended after a pre-set time period, set “ X-Ending ” by “ Time ”; if you want Step X to be ended when food internal temperature reaches a pre-set value, set “ X-Ending ” to “ Fd

Temp ”.

After you set “ X-Ending ” to “ Time ”, you will need to set “ X-Time ”. Here, “ X-Time ” is defined as the time duration (in hh:mm format) of the current step. The timer will start counting even if the cabinet temperature has not yet reached the target cabinet temperature. So, please make sure that the step time is long enough. If the step time is too short, the controller may continue to the next step no matter what the actually cabinet temperature is. If you set “ X-Ending ” to “ X-Fd Temp ”, you will need to set “ X-Fd Temp ” to the desired food temperature (Probe 2), but only one setting is relevant to the current cooking step depending on the X-Ending setting (either X-Time or X-Fd Temp ).

Figure 17. For each cooking step, set the target cabinet temperature, ending criterion, and timer or target food temperature.

If “ X-Ending ” of a certain step is set to “ Fd Temp ” while the food probe (Probe 2) is not plugged in, this step will never end. Cabinet probe (Probe 1) should always be plugged in, otherwise controller will stop sending power to the heater as protection. When all of

12/31

the “ X-Ending ” are set to time, the controller can operate with only the cabinet probe

(Probe 1) plugged in.

Note: user can also use Aubersmart app to view and change both time and food temperature of each step.

The example program for the controller is listed in Table 1. This program will control the temperature of the cabinet at 120°F for 2 hours. Then, change the temperature to

190°F. It will stay at 190°F until internal temperature of the meat reaches 160°F. Then, the controller will drop the temperature to 130°F for 20 hours, waiting you to pick the food. If you change set temperature in step 3 (Step 3 SmkrTemp) to 0 and time for step

3 to 0, when food internal temperature reaches 160°F, the controller will shut off the heater and stop the program. it will give beeping sound until the buzzer is muted or the power input has been reset.

A flow chart of how to enter the cooking profile is shown in Figure 18. To start program the cooking profile, press SET key shortly to enter the Cooking Profile Programming mode.

The top line in the display shows the step number “Step: 1” and the current target of cabinet temperature “SmkrTemp 250”. To enter or edit the profile:

1) Use ▲ or ▼ key to move the cursor “>” to the parameter you want to edit.

2) Press SET key, the value to be edited should start blinking.

3) Use ▲ or ▼ arrow key to edit the value.

4) Then press SET key again to save the change. That parameter will stop blinking.

5) Use ▲ or ▼ key to go another parameter, repeat the previous operations till you have finished entering all the cooking steps.

Note: New setting will NOT be saved if SET key is not pressed. After programming the necessary steps for cooking, you can finish programming by pressing the Time/Back key

Note 1.

Smkr Hi Alarm : This is the high temperature alarm for cabinet temperature

(Probe 1). When cabinet probe reading is higher than Smkr Hi Alarm , the buzzer on the controller will go off and the LCD display will flash between the normal display and the alarm display showing in Figure 22. The alarm has 1 degree hysteresis. The user can mute the buzzer by pressing either the Up key or the Down key. Temperature must move out of the hysteresis zone to activate the alarm again. For example, if Smkr Hi Alarm is set to 290°F, the buzzer will go off when Probe 1 reads higher than 291°F, and the buzzer will stop when Probe 1 reads lower than 289°F. To disable Smkr Hi Alarm alarm, you can set it to a large number, such as 750°F.

Figure 22. The LCD display when Smkr Hi Alarm is triggered.

Note 2. Smkr Lo Alarm: This is the low temperature alarm for cabinet temperature probe (Probe 1). When cabinet probe reading is lower than Smkr Lo Alarm , the buzzer on the controller will go off and the LCD display will flash between the normal display and the alarm display showing in Figure 23. The alarm has 1 degree hysteresis.

The user can mute the buzzer by pressing either the Up key or the Down key.

Temperature must move out of the hysteresis zone to activate the alarm again. For example, if Smkr Lo Alarm is set to 180°F. The buzzer will go off when cabinet temperature drops to 179°F; it will stop when temperature rise above 181°F. The Smkr

Lo Alarm is suppressed when the controller is just powered up. It will be activated when the cabinet temperature has reached the target cabinet temperature. To disable

18/31

the Smkr Lo Alarm , you can set it to a small number, such as 0°F (default).

Figure 23. The LCD display when Smkr Lo Alarm is triggered.

Note 3. Food Hi Alarm: This is the high temperature alarm for the food internal probe

(Probe 2). When food probe reading is higher than Food Hi Alarm , the buzzer on the controller will go off and the LCD display will flash between the normal display and the alarm display showing in Figure 24. The alarm has 1 degree hysteresis. The user can mute the buzzer by pressing either the Up key or the Down key. For example, if Food Hi

Alarm is set to 130°F, the buzzer will go off when Probe 2 reads 131°F, and the buzzer will stop when Probe 2 reads 129°F or lower. To disable Food Hi Alarm , you can set it to a large number, such as 650°F.

When smoking multiple pieces of meat of different sizes or thickness, you can put the probe in the thinnest piece first. Set the Food Hi Alarm to the temperature when meat is ready. It will let you know when it is done. Then, you can move the probe to the second thinnest pieces and so on. To use this feature, you can set the ending criterion to time. If you prefer to set the ending criterion to food temperature, then the Food Temp should be set to higher than Food Hi Alarm .

Figure 24. The LCD display when Food Hi Alarm is triggered.

Note 4. Probe3 Hi Alarm: This is the high temperature alarm for probe 3. When food probe 3 reading is higher than Probe3 Hi Alarm , the buzzer on the controller will go off and the LCD display will flash between the normal display and the alarm display showing in Figure 25. The alarm has 1 degree hysteresis. The user can mute the buzzer by pressing either the Up key or the Down key. For example, if Probe3 Hi Alarm is set to

130°F, the buzzer will go off when Probe 3 reads 131°F, and the buzzer will stop when

Probe 3 reads 129°F or lower. To disable Probe3 Hi Alarm , you can set it to a large number, such as 650°F.

Note 5. Relay Action: This is smoke generator relay setting. This parameter determines which steps to turn on smoke generator output. Its configuration range is from 0 to 63. It is determined by the following formula:

Relay Action = A * 1 + B * 2 + C * 4 + D * 8 + E * 16 + F * 32;

If A = 0, smoke generator output is OFF at Step 1.

If A = 1, smoke generator output is ON at Step 1.

If B = 0, smoke generator output is OFF at Step 2

If B = 1, smoke generator output is ON at Step 2.

If C = 0, smoke generator output is OFF at Step 3.

If C = 1, smoke generator output is ON at Step 3.

If D = 0, smoke generator output is OFF at Step 4.

If D = 1, smoke generator output is ON at Step 4.

If E = 0, smoke generator output is OFF at Step 5.

If E = 1, smoke generator output is ON at Step 5.

If F = 0, smoke generator output is OFF at Step 6.

If F = 1, smoke generator output is ON at Step 6.

Example:

To turn on smoke generator output on step 2 and step 3 only, this parameter needs to be set to 6. (0 * 1 + 1 * 2 + 1 * 4 + 0 * 8 + 0 * 16 + 0 * 32 = 6.)

To turn on smoke generator output on step 1 only, set this parameter to 1.

Note 6. P: Proportional Constant. The unit is 1 degree. This parameter controls the output of the controller based on the difference between the measured and set temperature.

Larger the P number means the weaker the action (lower gain). If P = 7, the proportional band is 7 degree. When the sensor temperature is 7 degrees below the proportional band

(10 degrees below the setting), the controller will have 100% output. When the temperature is 5 degree below the set point, the output is 71%. When the temperature is equal to the setting, the controller will have 0% output (assuming integral and derivative functions are turned off). This constant also affects both integral and derivative action.

Smaller P values will make the both integral and derivative action stronger. Please note the value of the P is temperature unit sensitive. If you found an optimized P value when operating the controller in Fahrenheit, to use in Celsius, that optimized P value needs to be divided by 1.8. This controller will automatically convert the current P value if you change the temperature display unit.

Note 7. I: Integral Time. The unit is in seconds. This parameter controls the output of controller based on the difference between the measured and set temperature integrated with time. For example, if I = 1000, it means if the temperature difference between the

20/31

cabinet temperature and set temperature stays constant, the output will be doubled after

1000 seconds. Integral action is used to eliminate temperature offset. Larger number means slower action. E.g. assuming the difference between the measured and set temperature is 2 degrees and remain unchanged, the output will increase continuously with time until it reaches 100%. When temperature fluctuate regularly (system oscillating), increase the integral time. Decrease it if the controller is taking too long to eliminate the temperature offset. When I = 0, the system becomes a PD controller. For very slow response system such as slow cooker and large commercial rice cooker, set I = 0 will significantly reduce the temperature overshoot.

Note 8. d: Derivative Time. The unit is in seconds. Derivative action contributes the output power based on the rate of temperature change. Derivative action can be used to minimize the temperature overshoot by responding its rate of change. The larger the number is, the stronger the action will be. For example, when the door of oven is opened, the temperature will drop at very high rate. The derivative action changes the controller output based on the rate of change rather than the net amount of change. This will allow the controller to act sooner. It will turn the heater to full power before the temperature drops too much.

Note 9. T: Control Cycle Time. The unit is second. This unit determines how long for the controller to calculate each action. e.g. If T is set to 10 seconds, when controller decide the output should be 10%, it will turn on the heater 1 second for every 10 seconds. This parameter should be set at 2 second for heating with an electric heater.

Note 10. Auto-tune: This parameter can be used to initial the auto-tune process. Set

Auto-tune to ON then press SET key to confirm. Once exit (in normal display mode), the display will flash alternately between normal display and auto-tune notification (Autotuning Please wait…), which indicates auto-tuning is in progress. When the display stops flashing, the auto-tuning process is finished. Now, the newly calculated PID parameters are set and are used for the system. The new parameters will store in the memory even the power is off. To cancel the current auto-tuning process, please set this parameter to

OFF. For more information about auto-tune, please see section 10.

Note 11. Save & Recall Recipes: This controller can save up to 6 pieces of smoking recipe (programs). Each recipe file can have up to 6 steps (C-1 to C-6). For convenience, we have pre-named these 6 pieces of recipe files as B1 (beef), B2, C1 (chicken), C2, F1

(fish), F2. These recipe files are all the same except their names, so you can store your special recipe to any of them. These recipes can be stored in the memory of the controller even when it is powered off. You can overwrite the exist recipe with a new one.

Figure 27. Access the parameters in System Config menu.

Note 12. Program Mode: Multi-step program switch. By default, this controller is set to multi-step mode, and this parameter is set to “ON”. If you want to change it to single-step mode, please change this parameter to “OFF”. For details regarding multi-step mode, please check section 4.1.3

Note 13. Output Hi Limit: It is expressed as a percentage value. This function will allow you to control the maximum output power delivered by the heater. For example, if you set Output Hi Limit = 50 and your heater is 1000 watts, the output will use 50% of the

1000 watts as the full output. It thinks the 1000W heater as a 500W heater. When the

23/31

PID algorithm determines 50% output value, the actual power output will be 250 watts.

This function can be used in two situations.

1) When you have a very powerful heater and using a very small pot of water to cook at very low temperature, for example, a 1400 watts heater with a one litter (1 qt) pot of water at 130°F. The heater is too powerful for the small water volume. The moment it is on, it releases too much energy to cause the temperature to overshoot. Although it is still possible to stabilize the temperature with proper PID parameters, it is much easier to control if you limit the maximum output to 25%. Ideally, an optimized temperature control system should consume about 25% of the heater power at set temperature

(steady state), for example, if you found out that only 50 watts of energy is needed to maintain the temperature at 60°C (141°F), ideally you should use only 200 watts heater for this job. Too much power will make the system over react too quickly. Too little power will make the system too slow in response. By using the Out function, you can make the

1400 watts heater to act as a 200 Watts heater for stable temperature control.

2) When the cooker consumes more power than controller can handle, for example, if you have a 12A, 120V AC heater and your cooker contains more than 38 Liter (10

Gallon) of water. It might take more than 90 minutes of full power heating for controller to heat up the pot. Long time of full power operation might cause the controller to overheat. You can set the output to 80%. It will prevent the controller from over heat by staying a full power too long. For details, please see Appendix 1.

Note 14. Temp Unit: You can set the display either Celsius (°C) or Fahrenheit (°F).

Note 15. Probe calibration offsets: These parameters are used to make the input offset to compensate the error produced by sensor. e.g. if the temperature displays of cabinet probe (Probe 1) is 2°C in ice water mixture, set Smkr Probe Offset = -2 will make the display to shown 0 degree. Three offset parameters are available for three probes. Smkr

Probe Offset is for cabinet probe (Probe 1); Fd Probe Offset is for food internal probe

(Probe 2); Probe3 Offset is for Probe 3.

Note 16. Probe3 Enabled: Probe 3 Readout Option. When this option is set to “Yes”, right bottom parameter in normal display mode will show the temperature of probe 3.

When this option is set to “No”, that location will show the current power output percentage instead. Please check section 3.1 for details.

Note 17. Step End Alarm: Step ending alarm setting. When Step End Alarm is set to

“ON”, the buzzer will beep 4 times when each step is finished. It is useful to notify the user the cooking step is finished. User can turn it off if no buzzer sound is wanted at the finish of each step.

24/31

Note 18. Backlight Level: LCD backlight level setting. The higher the value, the brighter the LCD display. 0 is lowest brightness. 10 is highest brightness.

Note 19. Dwell Time: Data Logging Sampling Interval. This parameter controls the temperature sampling interval, which will be used for data export function and plot display on Aubersmart app. The controller will store 5 data traces in total: SV, Probe 1 reading

(cabinet), Probe 2 reading (food probe), Probe 3 reading and the output power percentage. Each trace can store up to 300 data points. The temperature plot of the

Aubersmart App has two scales. One can display the latest 300 data points and other can display the latest 120 data points. The default setting of Dwell time is 1 minute per sample.

At this setting, 300 minutes (or 5 hours) of data points can be stored. User can display the plot in either 5 hours or 2 hours. The dwell time can be set in the range of 1 minute to

5 minutes. Table 4 shows the available plot scales for the corresponding dwell time.

If you want to change the dwell time in the middle of cooking, you will lose all the data logged before the change. If you want keep the data, you should export the data before change this setting.

Note 20. Password: Device access password. This parameter is used to lock the access to parameter settings on Aubersmart app. Default password is 777.

Note 21. Factory Reset: Factory reset. This function will restore all the parameters

(including all the stored recipe settings in the memory) back to the factory default values.

This setting will not reset the WiFi configuration. To reset the WiFi setting on the controller, please press and hold SET key and TIME key for 5s, until the blue WiFi indicator starts to blink.

Note 22. nFlt: Power line digital filter. This filter is for rejecting the power line interference.

There are three settings: “Auto” for auto-detect mode (default), “A” for 50 Hertz interferences and “B” for 60 Hertz interferences. If you encounter fast fluctuating temperature reading issue, you can change this setting to “A” or “B” manually, based on

25/31

your local power line frequency.

8. Important consideration for better control results.

The following is a list of things that could affect the result of temperature control. 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 black color smoker. The controller should be placed away from direct sun light also..

Users should also avoid exposing the controller to water and rain, which could damage the controller. b) Low temperature control. The control result for temperatures below 125 °F will not be as accurate as for higher temperatures when the smoker generator is on. This is because there are two heaters in the smoker tower. One is the smoker heater controlled by the PID controller. The other is the heater from the generator that is not controlled.

Our test shows that the heater in the generator itself can raise the temperature of the smoker tower by 60 °F (2 hours, in the shade with damper open). That means when the ambient temperature is at 70 °F, the smoker can be heat up to 130 °F in 2 hours by the heater of the generator (without using the heater in the smoker). 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 longer time to drop if it is overshot during initial heat up. At higher temperature, closing the damper will not affect the performance much because the heat loss from the wall of the tower is increased.

Close the damper at high temperature will keep the moisture of the food. d) Temperature uniformity of the smoker tower. Our test shows that when the all the shelves were empty, the temperature inside the smoker tower is fairly uniform except the back half of the lowest shelf that is close to the heater. User should avoid placing the sensor too close to the heater because it does not represent the temperature of the rest area. When the shelves are filled, temperature variation might depend on how the foods were placed. The bottom shelf can become hotter if more food is placed in it to block the hot air from going up.

9. Tuning the controller

This controller is shipped with the system parameters set for the Bradley Smoker. The user should not change these parameters if you want to control a Bradley Smoker.

Otherwise, if you feel that performance is not ideal, you can try to manually tune the

26/31

system or run the auto-tune again. For detailed information on how to tune the controller, please read the section 10 for tuning the controller.

10. Auto-Tune

This section can be ignored if you are using the controller to control the Bradley Smoker because the controller already set for it.

The controller's most powerful feature is its ability to regulate virtually any cooker with stable temperature control. For stable temperature control the controller requires two things; (1) the controller must be set to the correct power level (see next section) and,

(2) that it must be tuned to the cooker being used. Tuning is the process that matches the control characteristics of the controller to the heating characteristics of the cooker.

The controller is said to be tuned to the cooker when its memory is programmed with values telling it how fast the cooker warms up, cools off, and how efficiently it transfers heat. For example, consider the difference between a heat lamp and a hot plate. When electricity is applied to a heat lamp it begins to heat instantaneously, and when it's turned off it stops heating instantaneously. In contrast, a hot plate may take several minutes to begin heating when electricity is applied and even longer to start cooling when electricity is turned off. But, to do this it must be programmed with the time constants. Describing how fast the heater heats when electricity is turned on and how fast it begins to cool when it's turned off. These time constants are called the tuning parameters.

Every type of cooker has its own unique set of tuning parameters. For the controller to heat with stability, it must have programmed with the tuning parameters for the cooker currently being used.

When Should the Controller be Tuned?

If the PID parameters we provided are not working for your liking, you can use the autotuning function to let the controller to determine the PID parameters automatically. Autotuning function (it’s often known as self-tuning) can automatically optimize the PID parameters for your chosen cooking system. The auto-tuning function will heat up your cooker then let it cool down. It will repeat this heat/cool cycle several times. Based on the response time of the whole cooking system, the controller will calculate and set the

PID parameters for your cooker.

27/31

Figure 28. Auto-tune

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 room temperature pot filled with water 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. Set the controller to the appropriate power level (see next Section). Turn the controller and cooker on, and then enter the desired set point temperature closed to your normal cooking temperature.

To activate auto-tuning, enter Control Config menu. Go to parameter "Auto-tune", and set it to ON then exit the menu. the display will flash alternately between normal display and auto-tune notification (Auto-tuning Please wait…), which indicates auto-tuning is in progress. When the display stops flashing, the auto-tuning is finished. Now, the newly calculated PID parameters are set and are used for the system. The new parameters will store in the memory even the power is off.

You should always write down your old PID parameters, before letting the controller to perform auto-tuning. This way if something goes wrong, you can always go back to your old PID parameters. Or you can use factory reset feature (note 21) to reset all the parameters. The water amount in the pot should be the same volume as you would have normally used. Basically, you must setup your cooking system close to your actual cooking environment.

The duration of auto-tuning depends on how fast the system is responding to the heating and cooling cycle. If the temperature of the cooker takes a long time to drop when heater is off- the auto-tuning could be a very long tuning process. This is especially true with a well-insulated cooker. The auto-tuning should be able to tune most of your chosen with fairly good result.

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.

Sometime, the AC current requirement might not be marked on the cooking appliance. To find out how much current it will draw, divide the power (in wattage) by the line voltage, for example, an 1800 watts 120V heater will draw 15 A. A 2000 watts 240 V heater will draw 8.3 Ampere.

Why the heat becomes an issue?

The solid state relay (SSR) used in the controller is a critical component for the precision temperature control. With SSR, the power can be switched at high speed with no noise and no life time limitation. Compared with electromechanical relay, however, SSR has one drawback. It generates heat when passing the current. SSR is made of semiconductor that has a limited conductance. When passing current, the heat will be produced from the resistance. Each ampere of current will produce about 1.3 watts of heat. When 15 Amp is passing through the controller, 20 watt of heat is produced in the controller. As more heat is produced, the temperature inside the controller will rise. If it reaches to higher than 70 C, it can shorten the life or even damage some the components in the controller. The temperature inside of the controller depends on the amplitude of the current, how long the controller needs to run at full power and the ambient temperature.

The heat is only an issue during the start of the heating when the heater is running at full power. Once the temperature is close to the set point, the controller will probably need less than 50% of the power to maintain the temperature. Since the heat is directly related to the current passing the controller, the heat produced at steady state will be insignificant and can be ignored.

When the heat becomes an issue?

This controller can run at 12 A continuously without worry of the temperature of the controller. At 15A, the temperature of the controller will increase with time. The bottom of the controller where the heat sink is located can rise by 63F (35 C) from ambient if running at full power continuously for 90 minutes. For this reason we don’t recommend running the controller at full power for more than 90 minutes. For 120 VAC, 15 A for 90 minute will provide enough energy to heat 10 gallon (38 liters) of water up by 108F (60 C). If you

31/31

have a pot that is bigger than 10 gallon and the heater is drawing 18 A, and you need to raise the temperature by 108 °F, you better use one of the methods mentioned below to reduce the heat in the controller. Otherwise, you might damage the controller.

Please note that when the ambient temperature is hot, as it is often the case in some commercial kitchens, the temperature of the controller will get hotter. This is because the heat dissipation is mostly determined by the temperature gradient (the temperature difference between the ambient and the controller) instead of absolute temperature of the controller itself. If the controller reaches 50 °C when the ambient is at 20 °C, it will reach

70 °C when the ambient is at 40 °C.

Solutions to reduce the heat stress on the controller .

1) Use hot water. If you fill the pot with hot water that has a temperature close to the set temperature, the heat dissipation of the controller is not an issue. As we have mentioned, once the temperature is close to the set point temperature, the controller starts to pulse

(PWM) the power. The effective current is much lower, making heat not an issue.

2) Limit maximum output power. If you set output reduction parameter to 80%, then, a

18A heater will become a 14.4 A heater. It will take 25% longer time to heat up the pot, but the controller will not over heat.

In addition to these solutions, following information will also help you to manage the heat.

Place the controller in 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. Do not cover the controller with any insulation. If you are running at 18 A with a large pot, place the controller in a well-ventilated area and tilt the instrument up with its front leg will help it to remove the heat better. However, the tilted position might allow the water to be collected at the back frame. Although the controller is splash proof, you should avoid water to be dripped to the controller when open the lid of the cooker.

Increase the P value. This can only provide limited help for reducing the heat. P is the proportional band. P=200 means the proportional band is 20.0 degrees. When the temperature is raised to less than 20 degrees from the set point temperature, the controller will start to reduce the power sooner. But if the integration time is set to very short, the controller might start to run at full power again soon.
