Códigos de error en modelos de velocidad constante
Cuando el aire acondicionado falla, el receptor de temporización de la placa controladora, la luz de
avería de la placa PCB de la unidad exterior y el panel LCD del control remoto mostrarán el código de
avería correspondiente de acuerdo con las diferentes indicaciones de avería.
La respuesta específica es la siguiente:

POSSIBLE CAUSE
Refrigerant leakage
TA (indoor unit temperature
sensor) is abnormal
TWD (defrosting sensor sensor)
is abnormal
TE(indoor unit coil sensor) is
abnormal
Drainage system failure
Communication failure
Outdoor protection (phase
sequence)
TL(outdoor condensing tempe-
rature sensor) is abnormal
TP(Discharge temperature sen-
sor) is abnormal
Low pressure protection.
Outdoor protection (Discharge
temperature is too high.)
Communication failure between
indoor unit and outdoor unit.
Exhaust overtemperature pro-
tection.
Outdoor fan 1 # is abnormal
Indoor fan is abnormal
Outdoor temperature sensor
Compressor over-current pro-
tection
