The air ow setting other than the default value of 0.1inWG (25 Pa) may be changed to the
required external static pressure.
Setting of the air ow can be changed with the wireless remote controller, wired remote
controller, and simple remote controller.
How to set air ow (external static pressure)
W ● ireless remote controller
Air ow is set by function number 26 (static pressure).
Refer to "BUTTON NANE AND FUNCTION", "FUNCTION SETTING" and "FUNCTION
DETAILS" in 5-3 INDOOR UNIT (setting by wireless remote controller).
Wired remote controller ●
Air ow is set by function number 26 (static pressure).
Refer to "BUTTON NANE AND FUNCTION", "FUNCTION SETTING" and "FUNCTION
DETAILS" in 5-4. INDOOR UNIT (setting by wired remote controller).
Simple remote controller ●
Air ow is set by function number 26 (static pressure).
Refer to "BUTTON NANE AND FUNCTION", "FUNCTION SETTING" and "FUNCTION
DETAILS" in 5-5 INDOOR UNIT (setting by simple remote controller).
FAN PERFORMANCE CURVE ●
Refer to Chapter 4. INDOOR UNITS
Note
If air flow setting is unmatched, it is caused to be air flow down or water leakage due to ●
wrong operation.
Range of static pressure at ARU24 model is different from the others. ●
