Mitsubishi Electric TRANE NTXFKS09A112AA Service Manual page 15

The multi-flow vane is automatically set to the appropriate position.
In HEAT, the multi-flow vane automatically changes its position according to the indoor fan speed.
Even if 2 FLOW is selected, air will blow only from the top of the unit in the following conditions:
• During COOL/DRY: The room temperature is close to set temperature.
The air conditioner has operated for 0.5 to 1 hour.
• During HEAT: The air flow temperature is low. (During defrosting operation, start of operation, etc.)
NOTE:
Movement at the start of the 2 FLOW operation
• COOL/DRY, HEAT: It takes 0.5 to 1 minute to start the 2 FLOW operation.
• HEAT: When cold air blows out from the air outlet, the multi-flow vane may stop moving for up to 10 minutes to
make and blow out warm air.
(5) VANE AUTO ( ) mode
In VANE AUTO mode, the microprocessor automatically determines the horizontal vane angle to make the optimum
room temperature distribution.
In COOL, DRY and FAN operation
2 FLOW: Vane angle is fixed to position 2.
1 FLOW: Vane angle is fixed to position 1.
(6) STOP (operation OFF) and ON TIMER standby
In the following cases, the horizontal vane returns to the closed position.
(a) When STOP/OPERATE (OFF/ON) button is pressed (POWER OFF).
(b) When the operation is stopped by the emergency operation.
(c) When ON TIMER is ON standby.
(7) Dew prevention
During COOL or DRY operation with the vane angle at Angle 3 or 4 when the compressor cumulative operation time
exceeds 1 hour, the vane angle automatically changes to Angle 1 for dew prevention.
(8) SWING ( ) mode
By selecting SWING mode with VANE CONTROL button, the horizontal vanes swing vertically.
The remote controller displays "
(9) Cold air prevention in HEAT operation
The horizontal vane position is set to Upward.
(10) ECONO COOL ( ) operation (ECONOmical operation)
When ECONO COOL button is pressed in COOL mode, set temperature is automatically set 4 °F (2°C) higher by
the microprocessor. However, the temperature on the LCD screen on the remote controller is not changed. Also the
horizontal vane swings in various cycle.
SWING operation makes you feel cooler than set temperature. So, even though the set temperature is higher, the
air conditioner can keep comfort. As a result, energy can be saved.
To cancel this operation, select a different mode or press one of the following buttons in ECONO COOL operation:
ECONO COOL, VANE CONTROL, POWERFUL button.
OBHT752
In HEAT operation
2 FLOW: Vane angle is fixed to position 2.
1 FLOW: Vane angle is fixed to position 3.
". SWING mode is cancelled when VANE CONTROL button is pressed once again.
