Features:

Brand new and high quality. Can select cooling or heating operating mode.

Set the highest/lowest temperature limit to prevent accidents. Automatically starts cooling or heating to maintain a constant temperature.

Temperature calibration; you can calibrate the temperature according to your needs.

High temperature alarm: When the measured temperature reaches the set temperature, the controller triggers an alarm. Specifications: Material: Electronic component; Voltage: DC 12V/24V/110-220V (optional); Power: 120/240/1500W (optional); Weight: Approximately 48g/1.7oz. Package List: Circuit connection: Refer to the circuit diagram to connect the power supply and load. At this point, the digital tube (top) displays the actual measured temperature value, and the digital tube (bottom) displays the preset temperature. If the temperature sensor is missing or damaged, the digital tube will display "---", and the buyer should verify that the temperature sensor is installed before use. The temperature control output is a 10A relay, which can handle various high-power loads. Please ensure the circuit is correct.

Indicator light, digital tube status:

Indicator light: off means the relay is disconnected, and on means the relay is closed.

Digital tube: displays "-- --",

1. Check if the temperature sensor is missing or damaged

2. High-temperature protection in heating mode

3. Low-temperature protection in cooling mode.

The relay in protection mode is automatically disconnected.

Operation

SET Keys + Key: rapid accumulation of values

- Key: for rapid decrease of the value

Press Restart:

Restart the button SET Adjustment Key: accesses the temperature adjustment interface and the parameter adjustment interface of the SET two-layer interface. Briefly press the digital tube (at the bottom) to quickly adjust the temperature. By default - 20°C and 0°C, 20°C and 40°C, 60°C, 80°C, 100°C and other data sets, convenient quick recall for the user.

For example: users need to set 68.8°C, first briefly press SET to 60°C, then use the buttons to precisely adjust the corresponding temperature. After setting, wait 5 seconds for the data to be automatically saved to memory. Compared to the first generation thermostat, the second generation is more convenient and flexible to use, and the dual LED display of the actual temperature and the set temperature is easier to monitor. Long press SET to access the parameter setting interface. P0-p5 are the corresponding parameter settings. In the parameter setting menu, a short press of SET can be used to switch between p0-p5.

5.

To change a setting, simply navigate to the corresponding item and adjust it by adding or subtracting keys.

Press and hold SET to save the settings after adjustment, or wait 6 seconds for automatic saving.

Note: Setting P3 1 means the thermostat will stop working for 1 minute. Press and hold SET to reactivate it. Setting P4 1 means the thermostat will start working after 1 minute.

After setting, the digital display will not illuminate for up to 1 minute after normal operation. Press and hold SET to reactivate it.

P5 is set to OFF by default.

Once the user has set the temperature, the P5 can be switched ON to prevent others from changing it at will. Once switched ON, the data will be locked and the P5 will be switched OFF when it needs to be set again.
