NOTE:
When either of following operation is performed while A/C switch indicator is OFF, compressor control
change to ON but A/C switch indicator is not turned ON.
• AUTO switch is turned ON.
• Air outlet is set to D/F by MODE switch operation.
• Air outlet is set to DEF by DEF switch operation.
• Air inlet is changed to recirculation (REC) by intake switch operation.

OFF switch

Air conditioning system turns OFF and changes to the following status when switch is pressed while
air conditioning system is in the ON position.
• Air outlet: Foot
• Air flow: OFF
• Air inlet: Fresh air intake
• A/C switch: OFF

Temperature control dial

Setting temperature can be set within a range of 18

C (60

F) – 32

C (90

F) at a rate of 0.5

C (1

per adjustment using this dial.
• Clockwise rotation: Set temperature increases
• Counterclockwise rotation: Set temperature decreases
NOTE:
When air conditioning system is OFF position, setting temperature can be selected only while air con-
ditioning system state (when MODE switch is pressed) is indicated on the display.

AUTO switch

“AUTO” is indicated on display and air conditioning system operates according to the following setting
when switch is pressed.
• Air outlet: Automatic control
• Air flow: Automatic control
• Air inlet: Automatic control
• A/C switch*: ON
NOTE:
• When air outlet or air flow is manually operated while “AUTO” is indicated on display “AUTO” indi-

cation turns OFF. However, automatic control continues for other functions than air outlet or air flow.

• *: A/C switch (compressor control) is turned ON when AUTO switch is turned ON while A/C switch

indicator is OFF, but A/C switch indicator is not turned ON.

MODE switch

When each MODE switch is pressed, air outlet is switched and VENT, B/L, FOOT, or D/F

*1,2

can be

selected manually. (Switch indicator indicates air outlet status during automatic control.)
*1: Air inlet is set to fresh air intake (FRE) and A/C switch turns ON, when D/F is selected while air
conditioning system is in the ON position.
*2: A/C switch (compressor control) is turned ON when D/F is selected while A/C switch indicator is
OFF, but A/C switch indicator is not turned ON.
NOTE:
• Air outlet can be changed when air conditioning system is in the OFF position.
• Air outlet automatic control is released (“AUTO” turns OFF) when each MODE switch is pressed

while “AUTO” is indicated on display.

*1, 2

switch indicator ON: Fresh air intake

• Switch indicator blinks 2 times and air inlet is set to automatic control when switch is pressed and

held for 2 seconds or more. (Switch indicator indicates air inlet status during automatic control.)

*1: A/C switch turns ON when recirculation (REC) is selected while air conditioning system is in the
ON position.
*2: A/C switch (compressor control) is turned ON when recirculation (REC) is selected while A/C
switch indicator is OFF, but A/C switch indicator is not turned ON.
NOTE:
• Air inlet can be changed when air conditioning system is in the OFF position.
• Air inlet cannot be changed to recirculation (REC) when air outlet is in the D/F or DEF position.
• Air inlet automatic control is released when A/C switch is in the OFF position.
