Screen cleaning

Press SCREEN to lock the screen for cleaning. The

screen will remain locked for 30 seconds so you can

clean the screen without changing any settings.

After 30 seconds, press DONE to resume normal opera-

tion, or press SCREEN again if you require more time for

cleaning.

Note: Do not spray any liquid directly on the

thermostat. Spray liquids onto a cloth, then use

the damp cloth to clean the screen. Use water or

household glass cleaner. Avoid abrasive cleansers.
