that cannot be easily resolved.

system:
• Select a comfortable thermostat setting and leave it at chosen

depending on indoor air quality.
• Use drapes, curtains or shades to keep direct sunlight from heating
the room on very hot days.
• Limit the unit's run time by using the TIMER function.

• Turn on the air conditioning unit before the indoor air becomes too
uncomfortable.
