Wireless remote controller kit
Reason
Due to electrical noise
other than that from the
air conditioner, the
communication between
the units is cut off and the
unit stops.
When the noise is gone,
the unit automatically
restarts.
Reason
When operation
changeover is under
control, the control is set
to the mode that cannot
be carried out.
Reason
When the room
temperature reaches the
indoor unit set
temperature, the outdoor
unit stops and the air flow
rate of indoor unit drops
to the minimum.
This is to avoid the cold
air from getting in contact
with the people in the
room.
Reason
Because it is controlled
by microcomputer. Refer
to "AIR FLOW
DIRECTION ADJUST" on
page 5.
