(1) When the TS is changed.
(2) When the operation mode is changed from other mode to "COOL".
(3) When the fan control is changed from other position to "AUTO".
The fan speed is determined automatically in accordance
with the condition "(TR(corrected room temperature) - TS
(corrected set temperature)" as shown on the right.
However, the fan speed zone is determined in the manner
as the room temperature increases for the following cases.
Same as Cooling operation, fan speed is decided by the
difference between the room temperature and the set
temperature.
(1) The indoor fan starts operation 5 seconds after the electric expansion valve opens. However, when the indoor unit just
starts its operation or the operation mode is changed from other to "DRY" and the refrigerant circulation is not stopped,
the fan will rotate immediately without a delay time of 5 seconds.
(2) The indoor fan will stop in 30 seconds when the refrigerant circulation stops.
(3) The indoor fan will stop immediately when the indoor unit is stopped by pushing the stop button or by a setting of ON timer.
(4) When the refrigerant circulation is stopped due to a lower room temperature for more then 3 minutes, the fan will rotate
1 minutes at intervals of 3 minutes.
(5) When the indoor unit just starts its operation or the operation mode is changed from other to "DRY" and the refrigerant
circulation is stopped, the fan will rotate for 1 minute and then it will operate according to the statement (4).
