(ii) Fan speed control when the unit started
1) During heating and defrosting fan control
a) The outdoor unit’s fan is started in 4th speed simultaneously with the start of compressor operation.
b) After 20 seconds of operation in 4th speed, outdoor fan control in item (iii) is executed.
2) During cooling, dehumidifying
a) When the ambient air temperature (Tho-A) is 20°C or higher, the outdoor unit fan starts simultaneously with
the compressor. The fan operates at 4th speed for 20 seconds, and then outdoor unit fan control in item (iii) is
executed. (Normal control)
b) When the ambient air temperature (Tho-A) is lower than 20°C, the outdoor unit fan starts 10 seconds after the
compressor starts. The fan operates at 3rd speed for 20 seconds, and then outdoor unit fan control in item (iii)
is executed.
c) When the ambient temperature (Tho-A) is lower than 10°C, the outdoor unit fan starts 10 seconds after the
compressor starts. The fan operates at 2nd speed for 20 seconds, and then outdoor unit fan control in item (iii)
is executed. (only case of 302 model)
d) When the ambient air temperature (Tho-A) is less than –5°C, the outdoor unit fan starts 10 seconds after the
compressor starts. The fan operate 1st speed for 20 seconds, and then outdoor unit fan control in items (iii) and
(iv) is executed.
(iii) Outdoor unit fan control
1) Fan speed control during cooling and dehumidifying
The fan speed is changed in accordance with the outdoor unit heat exchanger temperature (Tho-R1, R2) and ambient
air temperature (Tho-A).
Note (1) Either the Tho-R1 or R2 temperature, whichever temperature is higher (Tho-R2 in models 802 and 1002 only).
