Outdoor unit alarm codes
If indoor unit filter lamp is flashing four times, this indicates an
outdoor unit fault. This is identified by the number of flashes on
LD 301, please see the table right.
If LD 303 is on permanently this is normal operation. If LD 301 is
lit in conjunction with LD 303 this indicates an overload (1)
condition but not an alarm. If LD 302 is lit in conjunction with LD
۳۰۳ this indicates an overload (2) condition but not an alarm and if
LD 301 and LD 302 are lit in conjunction with LD 303, this indicates
an overload (3) condition but not an alarm.
On Multizone systems only, if LD 301 is lit permanently and LD
۳۰۲ is flashing a number of times, this indicates a thermistor fault.
Please refer to the table right for the thermistor that is faulty.
If LD 304 is flashing, the number of flashes indicates a
communication error with the corresponding indoor unit circuit
number. Check cable connections, cable is not short circuited
or open circuit and PCB operation.
