4. Sending Commands from Controller
The operation commands are sent by
pressing the required operation switch by
facing the transmitter of the controller toward
the receiver of the indoor unit.
(1) When the commands are sent,
the “
” indication on the liquid
crystal display of the controller flashes
once.
(2) The indication lamp (yellow) on the
receiver part of the indoor unit turns
ON for an instant when the indoor unit
receives the commands.
ATTENTION:
In case that the indication lamp (yellow) does not turn ON although the commands are sent, the
commands are not received by the indoor unit. In such a case, send the commands again.
ATTENTION:
The transmitter of the controller has the vertical directivity to the receiver, and the permissible
angle for transmitting is within 50
o
. However, the capable distance for transmitting gets half when
the transmitting angle is 50
o
, and also get shorter in case that an electronic type light is used in
the room.
NOTE:
The above figure shows the case of a 4-way cassette type indoor unit. The figures for other models are
different partially.
LCD (Liquid Crystal Display) Indication
When viewed from certain angles the LCD can be difficult to read.
The viewing angle ranges from an optimal of 60
o
down to 30
o
, as
shown in the diagram on the right. If the viewing angle is below
30
o
, the indications not displayed are slightly faded so that makes
the indication be hardly readable. It is the characteristics of this
LCD, which is not abnormality.
