Operation flow and applicable data, etc.
The blowing air volume at the outdoor unit side is controlled.
Receiving the operation command from the controller of
indoor unit, the controller of outdoor unit controls fan speed.
* For the fan motor, a DC motor with non-stage variable
speed system is used. However, it is limited to 8 stages for
reasons of controlling.
Description
1) The operation command sent
from the remote controller is
processed by the indoor unit
controller and transferred to the
controller of the outdoor unit.
2) When strong wind blows at
outdoor side, the operation of air
conditioner continues with the
fan motor stopped.
3) Whether the fan is locked or not
is detected, and the operation of
air conditioner stops and an
alarm is displayed if the fan is
locked.
4) According to each operation
mode, by the conditions of
outdoor temperature (To) and
compressor revolution, the speed
of the outdoor fan shown in the
table is selected.
2) Fan speed ≥ 400
when the motor stopped.
