Receiver
The signal receiver, with the exception of the separately installed signal
receiver, is mounted on the unit.
A: Receiver
This section picks up infrared signals from the wireless remote control unit
(transmitter).
Indication lamps
One of these lamps will blink when trouble has occurred. When an indicator lamp
starts to blink, refer to “Troubleshooting” on page 16.
B: Operation lamp
This lamp lights when the appliance is turned on.
C: Timer lamp
This lamp lights when the system is being controlled by the timer.
D: Standby lamp
•
This lamp lights at the following times during heating operations:
When operation has started, when the thermostat has been activated, during
a defrosting operation
•
The lamp blinks when trouble has occurred.
E: Emergency operation
button
This is used when operation cannot be performed due to trouble with or loss of
the wireless remote control unit.
F: ADDRESS switch
This switch is used in order to prevent the sending of signals to the wrong indoor
unit when a multiple number of indoor units that can be operated by the wireless
remote control units have been installed in the same room.
G: SWING button
When this button is pressed, the airflow sweeps up and down automatically.
H: FILTER lamp
This lamp lights to indicate that it is time to clean the filter.
•
If two beeps are heard, the operation lamp among the indication lamps has lighted and the timer lamp
and standby lamp blink alternately in cases where heat pump models are used, this indicates a
cooling/heating mode mismatch and, as such, operation in the desired mode cannot be performed.
(The same beeps will be heard and the same operation lamps will light when auto cooling/heating has
been selected on a model which does not have the auto cooling/heating function.)
•
When local operation has been set to disable because the centralized control mode is established, for
instance, pressing the ON/OFF operation button, MODE button or temperature setting buttons results
in the sounding of five beeps, and the attempted change in the operation will not be accepted.
