<Indicating a failure on the indoor
unit side>
<Indicating a failure on the outdoor
unit side>
Description
•
The “timer lamp” indicates a mode of failure detected
on the indoor or outdoor unit side by blinking
frequency.
•
A failure detected on the outdoor unit side will be
indicated by the “timer lamp” blinking 4 times after a
retry operation has been performed several times.
Note: In some failure modes, only the retry operation is
repeated without lamp indication.
<Failure modes that will repeat a retry operation without
the indoor unit lamp indication are as follows:>
OH thermistor temperature rise
Outdoor unit communication error
Power voltage abnormal
Less frequent defects
•
The “LD301” indicates a mode of failure detected on
the outdoor unit side by blinking frequency.
Upon failure detection, the outdoor unit will shut down
and the LD301 continues to blink until the unit is reset.
(In the event of communication errors, the LD301
continues to blink until communication is restored.)
