When the
remote
controller
installation site
is bad.
If the cold or warm air blown out from the air conditioner
directly contacts the thermostat section of the remote
controller, the outlet temperature of the air conditioner
may be sensed and room temperature control will be
different from the room temperature, and “not cooled” or
“not heated” or other trouble may occur.
In addition, there is the possibility that the same kind of
trouble may also occur when the remote controller is
effected by direct sunlight.
1. Install the remote controller
where it will not be directly
exposed to the cold or hot air.
2. Install the remote controller
where it will not be directly
exposed to sunlight or strong
lighting.
When
installation
environment is
quiet.
When the wall mounted type was installed in a bedroom,
living room, or other quiet place, the sound of the
refrigerant flow may be sensed as noise and must be
taken into account.
1. Plan installation of a model
with external expansion valve.
2. Plan installation of a branch
box farther from indoor unit.
3. Plan installation using another
air conditioner.
When using the
wireless
remote
controller.
Signals may not be received when using it in a room
illuminated by an inverter fluorescent lamp.
Turn on the fluorescent lamp and
check if the indoor unit receives the
signals from the remote controller.
If the indoor unit does not receive
the signals, consult an authorized
service personnel.
When installing
the inverter
type.
It may generate noise in TV sets, stereos and PCs. The inverter type should be
installed at a sufficient distance
from these equipments.
