TYPICAL OPERATION

How your EVO unit works in cooling

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’s cooling capacity decreases
as the outdoor temperature increases. This causes the
EVO to work harder and longer to hold the selected room
temperature. Your evo unit will operate in cooling down to
41°F (5°C)

Indoor Coil Freeze Protection

• Frost may form on the indoor coil during cooling
operations when the outdoor temperature below 50°F
(10°C). Prolong operation may cause ice to form on the
indoor coil and block airfl ow. If the EVO indoor unit
microcomputer detects ice on the indoor coil it will stop the
compressor to defrost the coil and protect the unit.

How your EVO unit works in heating

In heating mode, your EVO outdoor unit will absorb heat
from the outdoor ambient, then the EVO indoor unit will
discharge the heat to the room. The EVO’s heating capacity
decreases as the outdoor temperature decreases. Your evo
unit will heat down to 5°F (-15°C).

During extreme cold outdoor temperatures, you may need
an additional heating source to supplement the EVO
heating output.

Defrost Function

• In heating mode, frost may form on the outdoor coil during
humid and low outdoor temperature conditions. Prolong
operation may cause ice to form on the outdoor coil and
block airflow. This will reduce the EVO’s heating capacity.
If the EVO microcomputer detects ice on the outdoor coil,
it will switch automatically to defrost mode to melt the ice
and clear the coil. During defrost mode, heating will be
discontinued and the EVO indoor unit will flash the Defrost
indicator. The compressor will continue to run while
indoor and outdoor fans will stop. It is normal to see steam
or vapor coming from the outdoor unit during defrost
mode. Defrost mode will terminate 12 minutes after
initiation of defrost cycle or when the outdoor coil
temperature is 50°F (10°C) or greater.
