1. Press the SET key to display "SC", and the green display will display the value of this parameter. Select shift, increment and decrement keys to set or modify this parameter. This function can be used to correct the measurement deviation when the thermostat runs for a long time. If the measured value is less than 2 degrees Celsius, this parameter can be set to 02; If the measured value is greater than 2 degrees Celsius, this parameter can be set to minus 2.
2. Select shift, increment and decrement keys to set or modify this parameter.
3. When the temperature controller produces measurement deviation after long-term operation, you can use this function to correct the error.
4. When the measured value is less than 2 degrees Celsius, you can set this parameter to 02.
5. If the measured value is greater than 2 degrees Celsius, you can set this parameter to minus 2.
