SYSTEM OPERATION COOLING OPERATION How it works: In cooling mode, your evo+ indoor unit will absorb heat from the room, then the evo+ outdoor unit will discharge the heat to the outdoors. The evo+ cooling capacity decreases as the outdoor temperature increases. This causes the evo+ to work harder and longer to hold the selected room temperature.
ENERGY SAVING TIPS 1. Relaxing room temperature at night is OK: During the nighttime hours you don't require the same level of conscious cooling or heating. Try using Sleep Mode to gradually relax room temperature and allow the unit to run less and save energy. 2. Curtains and shades: In the summer, you need to block the effects of the sun. Close window curtains and shades on the south and west side of your home to help block solar heat. In winter, the sun is your friend.
