Description 1. Temperature setting: The ambient temperature required by the user can be adjusted on the thermostat or via the APP. The adjustment range is 40 to 99 degrees Celsius. 2. Temperature difference setting: Set the difference between heating and cooling target temperature. For example, when working at a constant temperature, the target temperature is 40 degrees Celsius and the temperature difference is set to 2 degrees Celsius. Heating stops after heating to 40 degrees Celsius and goes to constant temperature mode. When the temperature drops to 38 degrees Celsius, it returns to heating mode. This value differs by 2 degrees Celsius and can be adjusted by the user or via the APP. 3. Compressor delay: This function is generally used for compressor cooling. If the temperature controller is used for a refrigerator or freezer, this value must be set. The general setting value is 3-6 minutes according to the back pressure of the compressor. The APP adjustment range is 0 to 10 minutes. 4. Temperature correction: Used to correct the temperature value currently detected by the thermostat. The correction range is 0 to 10 degrees Celsius.
