5. Dew prevention
During COOL or DRY operation with the vane angle at Angle 4 or 5 when the compressor cumulative operation time
exceeds 1 hour, the vane angle automatically changes to Angle 1 for dew prevention.
6 SWING MODE (
)
By pressing the SWING button, vane swings horizontally. The remote controller displays “
”.
SWING MODE is cancelled when any of the following operations are performed.
●
The unit is turned off.
The vertical vanes will return to their positions just before the swing operation was started.
●
The operation mode(AUTO, COOL, DRY or HEAT)is changed.
The vertical vanes will return to their positions just before the swing operation was started.
●
The SWING button is pressed.
The vertical vanes stop at the position when the button is pressed.
3. Positioning
The vane is once pressed to the vane stopper below to confirm the standard position and then set to the desired angle.
The positioning is decided as follows.
(a) When the OPERATE / STOP(ON / OFF) button is pressed.(POWER ON/OFF)
(b) When the vane control is changed AUTO to MANUAL.
(c) When the SWING is finished.
(d) When the test run starts.
(e) When the power supply turns ON.
4. VANE AUTO (
) mode
In VANE AUTO mode, the microprocessor automatically determines the vane angle and operation to make the optimum
room-temperature distribution.
(1) In COOL and DRY operation
(2) In HEAT operation
Vane angle is fixed to Angle 1.
Vane angle is fixed to Angle 4.
9-6. AUTO VANE OPERATION
1. Vane motor drive
These models are equipped with a stepping motor for the horizontal vane. The rotating direction, speed, and angle of the
motor are controlled by pulse signals (approx. 12V) transmitted from indoor microprocessor.
2. The horizontal vane angle and mode changes as follows by pressing the VANE CONTROL button.
