Yes. In standby mode, press and hold the "UP" and "DOWN" keys for 5 seconds, and the SET window will display "PO"--P5. Then press the "DEFROST" key to adjust the window to display the "P4" value {range 1-10, press the "UP" and "DOWN" keys to adjust the value}. The user can adjust it to around 05 degrees. After 10 seconds, do not press any key to exit. The system automatically saves the parameters and returns to standby mode.
