How do I safely clean the thermostat screen?
Use the Clean Screen option to disable the touchscreen for 30 seconds while you clean it. To activate it, touch Menu, navigate to CLEAN SCREEN, and touch Select — a countdown timer will display the time remaining until reactivation. To clean, spray water or household cleaner onto a cloth and use the cloth on the screen; avoid abrasive cleaners and do NOT spray liquid directly on the thermostat. (Page 24)
