Specifications

(16) Self diagnosis function

When something abnormal happens on the outdoor unit, indoor unit fan motor and each sensor (heat exchanger, room tempera-

ture,) it will be indicated by flashing lamps.

(a) Abnormality of outdoor unit:

1) Cooling operation

When the indoor heat exchanger temperature does not fall to 25˚C or below for 40 minutes after 5 minutes have elapsed since

the compressor operation start, the abnormality stop occurs. (The timer lamp flashes 5 times.)

(b) Abnormality of indoor fan motor:

When the status that the fan motor speed is 300 rpm or under continues for 30 seconds or more during the indoor fan motor

operation, the unit is stopped. The fan motor operation is restarted after 10 seconds, however, if the fan is stopped again, the

air-conditioner is completely stopped as the indoor fan motor abnormality and the abnormality indication is displayed. (The

operation lamp flashes 6 times.)

RUN lamp will flashing when the input temperature of the heat exchanger thermistor measures less than –20˚C for more than

3 seconds with the air-conditioner “OFF”. (will not flashing during operation)

(d) Abnormality room temperature thermistor:

RUN lamp will flashing when the input temperature of the room temperature thermistor measures less than –20˚C for more

than 3 seconds with the air-conditioner “OFF”. (will not flashing during operation)

Note (1) If the above abnormalities happen concurrently, the lamp will flashing in the order of item number (a) through (d) above.

(15) Economy operation (Remote controller “ECONO” button on)

(a) Cooling economy operation

The set temperature is raised by 2˚C and the unit is operated in cooling mode.

(b) Thermal dry economy operation

Thermal dry operation carried out at 2˚C higher than the set temperature.

The indoor fan is controlled as follows.

(13) Three-minute forced operation

When the compressor begins operating the thermal operation is not effective for 3 minutes, so operation continues as is in the

operation mode. (After 3 minutes has passed the thermal operation is effective.)

However, stopping the compressor via a stop signal or protection control has priority.

(14) High power operation (Remote controller “HI POWER” button on)

The indoor unit fan rotates at speed 6 for 15 minutes, and carries out continuous cooling and Fan.
