Notes (1) Fan motor speed for model 200 and 250 are same for both top and bottom lines
(2) Value in ( ) are for the model 125, 140.
(3) Value in ( ) are for the model 250.
(b) Fan tap control during Cooling/Defumidifying operation
Fan taps are selected depending on the outdoor unit heat exchanger temperature (Tho-R1, R2) and the outdoor air temperature (Tho-A).
Note (1) It is detected by Tho-R1 or R2, whichever the higher.

(d) Outdoor unit fan control at cooling low outdoor air
1) When all the following conditions are established after the start of compressor, the following control is implemented.
If the outdoor air temperature (Tho-A) is in the zone in the cooling/dehumidifying mode, it has elapsed 20
seconds from the start of outdoor unit fan and the outdoor unit fan is at the tap 1 speed, the outdoor unit fan speed is
controlled according to the outdoor unit heat exchanger temperature (Tho-R1, R2).
Note (1) It is detected with Tho-R1 or R2, whichever the higher.
