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.
Ô
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.
- 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.

The above figure shows the case of a 4-way cassette type indoor unit. The figures for other
models are different partially.
