Steps
1. Connect power supply: use single-phase AC220V/50Hz power supply.
2. Setting parameters: Select Chinese or English through the LCD display, set the temperature (0~ 65 ° C), humidity (40~ 95% R. H), and time (0~ 99 hours or 0~ 9999 minutes).
3. Start operation: After confirming the setting, the device starts to work, and the controller displays the status of temperature, wind speed, running time, etc.
4. Monitoring and adjustment: Multiple devices can be connected through the RS485 interface for real-time monitoring, or remotely controlled using optional software.
5. End operation: stop automatically after completion of operation, or stop manually.
Notice
• Ambient Temperature should be kept at 10~ 30 ℃ and humidity below 70%.
• Avoid opening doors frequently to maintain a stable temperature.
• Regularly clean liners and shelves to ensure hygiene.
• Check whether the over-temperature protection function is normal before use.
• Disconnect the power supply during maintenance, and the electrical control components are located at the back of the box.
• Follow safety standards and deal with alarms promptly.
