Features:
Brand new and high quality.
Can select cooling or heating operating mode.
Set the highest/lowest maximum 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 element Voltage: DC 12V/24V/110-220V (optional) Power: 120/240/1500W (optional) Weight: Approx. 48g/1.7oz Package list: 1 x Digital thermostat temperature alarm controller sensor Circuit connection: Refer to the circuit diagram to connect the power supply and load. At this time, the digital tube (top) displays the actual measured temperature, 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 check if 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 is automatically disconnected in protection mode.
Key Functions: The thermostat panel has three keys: + Key, - Key, and SET Key.
+ Key: Quickly increases the value.
- Key: Quickly decreases the value.
Press Restart: Restarts the button.
SET Key: Accesses the temperature setting interface and the two-layer interface parameter setting interface.
SET: Briefly press the digital tube (at the bottom) to quickly set the temperature. Default values ​​are 20°C and 0°C, 20°C and 40°C, 60°C, 80°C, 100°C, and other values, providing convenient quick access for the user. For example: users need to set 68.8°C, first briefly press SET at 60°C, then use the buttons to precisely adjust the 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. Press and hold 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 and p5. To change a parameter, 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. Reminder: 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 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, P5 can be set to ON to prevent others from changing it at will. Once set to ON, the data will be locked and the P5 will be set to OFF when it needs to be set again.
