5. Temperature, Humidity Range and Set value at factory

6. How to correct the temperature value

To correct the temperature value, locate a short bar on the bottom left of the unit when the back cover is open. Shorting the GND and UP terminals will increase the displayed temperature by 1 degree. Shorting the GND and DOWN terminals will decrease the displayed temperature by 1 degree.

7. A simple troubleshooting technique

If an error is displayed while using the product:

• Er: Displayed when the DATA memory element is damaged inside the product due to powerful external noise. Contact the company for customer service. While the controller has supplementary measures for outside noise, it cannot endure infinite noise. Noise (2KV) abnormality may damage the unit's interior.
• E (Open Error) or 5-E (Short Error): The sensor has a defect. Please check the sensor.
