Outdoor heat exchanger thermistor : -50°C or lower
Ambient air temperature thermistor : -30°C or lower
Low pressure sensor:
0 V or lower, or 3.49 V or higher.
(ii) Discharge pipe temperature thermistor, suction pipe temperature thermistor, under-dome temperature thermistor. (models
802, 1002 only)
After the compressor goes ON, if the following is detected for 5 seconds continuously between 10 minutes and 10 minutes
20 seconds after the compressor goes ON, the compressor stops. After a 3-minute delay, the compressor is restarted, but
if this state is detected 3 times within a 40-minute period, an anomalous stop occurs.
Note (1) This is not detected during defrosting and for 3 minutes after defrosting.
Discharge pipe temperature thermistor: -10°C or lower
Suction pipe temperature thermistor:
-50°C or lower
Under-dome temperature thermistor:
-50°C or lower
(k) Test
operation
( i ) It is possible to operate the outdoor unit using SW3-3 (SW5-3) and SW3-4 (SW5-4) on the outdoor unit PCB.
Be sure to turn SW3-3 (SW5-3) OFF when operation ends.
(ii) Test operation control
1) The air conditioner is operated at the predetermined maximum speed for each model.
2) Each protective control and anomalous sensing control is activated.
3) If the setting of SW3-4 (SW5-4) is changed during test operation, and the compressor is stopped temporarily, and
operation mode is switched between cooling and heating.
4) Set point and indication on the remote controller follows the below table.
(i)
Silent mode control
Silent operation in done according to the remote control function setting.
( i ) Fan speed is reduced in comparison with normal operation mode specifi ed in item.
1) Fan speed during cooling and dehumidifying operation.
2) Fan speed during heating
(ii) Maximum compressor speed is limited as mentioned in the following table.
