Outdoor fan control
(a)
Outdoor fan speed and fan motor rotation speed
The 7th outdoor fan speed in the following table is specified as the rated speed. Under the normal control, the speeds up
to 9th level are used.
Note (1) Heating 9th speed changes it depending to outdoor air temperature Tho-A as follows.
(b)
Fan control during cooling
During cooling and dehumidifying, fan speed is controlled in accordance with the high pressure (sensed by PSH) and the
outdoor air temperature (sensed by Tho-A).
(i)
Initial fan speeds are as follows.
Initial ourdoor fan speed at cooling
(ii)
Speed changes depending on high pressure value.
(iii)
Under low outdoor air temperature condition, the stepless fan control between 130-300min
-1
is performed.

The fan speed control is performed based on the low pressure (detected with PSL) during heating operation.
Initial fan speed is 6th speed.
Speed changes depending on low pressure value.
