How to Use:

1. Temperature setting: During measurement and control mode, press the upper or lower button to set the temperature (stop temperature). If no button is pressed for 5 seconds, the set stop temperature will be saved and the device will return to measurement and control mode. The temperature control output is described as follows: Cooling: When the freezer temperature is above the set temperature value (corresponding to the SET temperature setting value) + control deviation (E3), and the minimum compressor start interval has elapsed, cooling starts. When the freezer temperature is below the set temperature value (corresponding to the SET temperature setting value), cooling is deactivated. Resetting settings: Press and hold the upper and T buttons for more than 5 seconds; the display will show YES to restore factory settings. 2. Power On: In the power-on state, press and hold the power button for 5 seconds to switch to the power-off state; the interface will display "OFF". In the power-off state, press and hold the power button for 5 seconds to return to the power-on state; the measurement and control status will be displayed.

Note:

1. Strictly distinguish between sensor cables, power lines, and output relay interfaces, and do not connect them incorrectly. The supply voltage should not exceed the rated voltage range of 220V ± 10%. Wiring connections must be made with the power off. 2. It is forbidden to use this machine in environments where there is continuous spraying of water mist or excessive humidity (relative humidity > 90%, condensation present). It is forbidden to use it in high-temperature environments, areas with strong electromagnetic interference, or highly corrosive environments. 3. The supply voltage must be consistent with the voltage indicated on the machine, and the stability of the supply voltage must be ensured. 4.To avoid possible interference, it is recommended to keep an appropriate distance between the sensor wires and the power lines. 5. When installing the evaporator sensor, the sensor must be tightly fixed to the copper pipe 5 cm from the evaporator inlet to ensure good contact between the sensor and the copper pipe.
