Press the "Settings" button once, and the "Stop Temperature" will start flashing. Use the "-" and "+" buttons to set the desired temperature value, ranging from -40 ℃ to 120 ℃. (There is a decimal point display from -9.9 ℃ to 99.9 ℃, with a resolution of 0.1 ℃. If not in this range, there is no decimal point display, with a resolution of 1 ℃.) Press the "Settings" button again, and the "Start Temperature" will start flashing. Use the "-" and "+" buttons to set the desired temperature value, ranging from -40 ℃ to 120 ℃. Press and hold the numbers to quickly change, with a user-friendly design. Press the "Settings" button again to exit the settings mode. For example, if the "stop temperature" is set to 28.8 ℃ and the "start temperature" is set to 25.5 ℃, the LCD screen will display the "sun" icon (if the stop temperature is greater than the start temperature, the heating control mode will display the "sun" icon). When the probe senses that the "measured temperature" is 24.2 ℃, the green indicator will light up and the output socket will have power output; When the probe senses that the "measured temperature" is 28.8 ℃ or above, the green indicator light will turn off and the output socket will be powered off. Then wait until the measured temperature value is less than or equal to 25.5 ℃ before cycling the above working process. At this moment, the temperature value of the controlled area is stable between 25.5 and 28.8 ℃, and this mode is the heating control mode.

Press the "Settings" button once, and the "Stop Temperature" will start flashing. Use the "-" and "+" buttons to set the desired temperature value, ranging from one

Between 40 ℃ and 120 ℃. There is a decimal point display from -9.9 ℃ to 99.9 ℃, with a resolution of 0.1 ℃. There is no decimal point display outside of this range, with a resolution of 1.

C) Press the "Settings" button again, and the "Start Temperature" will start flashing. Use the "-" and "+" buttons to set the desired temperature value, ranging from -40 ℃ to 120 ℃. Press and hold the numbers to quickly change, with a user-friendly design. For example, if the "stop temperature" is set to 25.5 ℃ and the "start temperature" is set to 28.8 ℃, the LCD screen will display the "snowflake" icon. When the probe senses that the "measured temperature" is 30.2 ℃, the green indicator light will light up and the output socket will have power output; When the probe senses that the "measured temperature" is 25.5 ℃ or less, the green indicator light will turn off and the output socket will be powered off. Then wait until the measured temperature value is greater than or equal to 28.8 ℃ before cycling the above working process. At this moment, the temperature value of the controlled area is stable between 25.5 and 28.8 ℃, and this mode is the cooling control mode.

Press and hold the "Calibration" button for more than 3 seconds to enter temperature calibration mode. When the temperature is between -5.9 and+5.9 ℃, select 0 to not calibrate. The default value is 0 at the factory.

All parameter settings have a memory function, which can be remembered within 10 seconds without operation and will never be lost.

This thermostat is a universal thermostat suitable for temperature control in places such as boilers, water pumps, water heaters, heating equipment, geothermal water heating, geothermal films, underfloor heating, heating cables, electric beds, electric heating paintings, hot and cold ventilation fans, insulation boxes, breeding farms, breeding rooms, bacterial fermentation, seed germination, etc. When the set temperature control value is reached, there is no delay function and it responds immediately. The minimum hysteresis is 0.1 ℃ (hysteresis=stop temperature start temperature or start temperature stop temperature), and it is recommended that the hysteresis be greater than 0.2 ℃.

Avoid frequent device startup. The mode has corresponding "snowflake" or "sun" icon indications, which are clear at a glance. If the values of "stop temperature" and "start temperature" are the same, the thermostat will not have an output.

Sensor malfunction open circuit or short circuit, or temperature below -40 ℃, or above 120 ℃, the digital display shows "Err." buzzer alarm, cuts off output, and the green indicator light goes out.
