Setup

1. Mounting: The control box features mounting points for easy installation. Secure the unit in a stable, dry location away from direct heat or excessive moisture.
2. Sensor Placement: Insert the L-shape temperature sensor into the environment or substance you wish to monitor and control. Ensure the sensor tip is fully immersed or positioned correctly for accurate readings. The L-shape design helps protect wires from direct heat.
3. Connecting the Device: This is a plug-and-play device. Connect your heating or cooling appliance (e.g., electric smoker, heater, cooler) to the output receptacle on the control box.
4. Power Connection: Plug the control box's power cord into a standard 100-120V AC/DC electrical outlet.
5. Circuit Breaker: Ensure the integrated 15 Amp circuit breaker is in the "ON" position.

Operating Instructions

Basic Operation

• The large LCD display will show the current temperature.
• Use the "Set" button to enter the setting mode.
• Use the Up and Down arrows to adjust values.
• The device supports dual heating and cooling functions.

Setting Temperature

1. Press the Set button once. The display will show the current set temperature.
2. Use the Up or Down arrows to adjust the desired temperature set value.
3. Press Set again to confirm and exit, or wait a few seconds for it to auto-save.

Adjusting Temperature Difference (Hysteresis)

The hysteresis setting determines the temperature range within which the device will operate before activating or deactivating the connected appliance. This prevents rapid cycling of the appliance.

1. Press and hold the Set button for approximately 3 seconds to enter advanced settings.
2. Navigate through the settings using the Set button until you find the hysteresis setting (often labeled as "d" or "dif").
3. Use the Up or Down arrows to adjust the value (range: 0.1 - 25 degrees).
4. Press Set to confirm and move to the next setting, or wait to exit.

Temperature Calibration

If you suspect the temperature reading is inaccurate, you can calibrate the sensor.

1. Press and hold the Set button for approximately 3 seconds to enter advanced settings.
2. Navigate to the calibration setting (often labeled as "CA" or "P7").
3. Use the Up or Down arrows to adjust the offset (up to 9 degrees in each direction).
4. Press Set to confirm.

Timer Function

The device includes a timer function (0-999 minutes) with two types of timer actions.

1. Access timer settings through the advanced menu (press and hold Set).
2. Locate the timer setting (refer to the specific menu code in the full manual if available, otherwise experiment).
3. Adjust the desired timer duration and select the timer action type.
4. Confirm settings.

Switching Between Celsius and Fahrenheit

The unit supports both Celsius and Fahrenheit display modes.

• Refer to the device's specific button combination or menu option for switching temperature units. This is typically found within the advanced settings.

Audible Alarms

The control box is equipped with audible alarms for high and low temperature limits.

• Set the high temperature alarm (AH) and low temperature alarm (AL) values in the advanced settings.
• An alarm will sound if the measured temperature exceeds the high limit or falls below the low limit.

Maintenance

• Cleaning: Wipe the control box with a soft, damp cloth. Do not use abrasive cleaners or solvents. Ensure the device is unplugged before cleaning.
• Sensor Care: Handle the temperature sensor with care. Avoid bending the cable sharply or exposing the sensor tip to extreme physical stress.
• Storage: When not in use, store the device in a cool, dry place, away from direct sunlight and extreme temperatures.
• Circuit Breaker: The integrated 15 Amp circuit breaker protects the device from overcurrent. If it trips, disconnect the appliance, reset the breaker, and investigate the cause of the overload before reconnecting.
