Happy to help! We might need to reboot the system. Please turn the unit to the off setting for about 10 minutes to clear any errors. Afterward, please turn it back on and set it to "Low" and "Cool", and at about 70 degrees. It'll likely display the word "Wait" at that time - please don't alter any settings, as it will clear on its own. Let me know if that does the trick - standing by.
