00: When the outdoor unit is stopped, the indoor unit fan operates continuously following
the setting on the remote controller.
01: When the outdoor unit is stopped, the indoor unit fan operates intermittently at a very
low speed.
02: Enable or disable this function by remote controller setting.
*When using a wired remote controller without Indoor unit fan control for energy saving for
cooling function, or when connecting a single split converter, the setting cannot be made
by using the remote controller. Set to “00” or “01”.
To confirm if the remote controller has this function, refer to the operating manual of each
remote controller.

Temperature correction
NOTE:
When changing Function 95, perform this setting before other Room temp. control settings
(Function 30, 31, 92, 93).
If Function 95 is not set first, Room temperature control settings (Function 30, 31, 92, 93)
will be reset and you must re-do them again.
Heat Insulation condition (building insulation)
Heat insulation conditions differ according to the installed environment.
“Standard insulation” (00) allows system to rapidly respond to the cooling or heating load
changes.
“High insulation” (01) is when the heat insulation structure of the building is high and does
not require system to rapidly respond to cooling or heating load changes.
When “High insulation” (01) is selected;
• Overheating (overcooling) is prevented at the start-up.
• All room temp. control settings (Function 30, 31, 92, 93) will reset to “No correction” [0.0°F
(0.0°C)].

Room temperature control for indoor unit sensor
Depending on the installed environment, correction of the room temperature sensor may
be required.
Select the appropriate control setting according to the installed environment.
The temperature correction values show the difference from the “Standard setting” (00)
(manufacturer’s recommended value).
* When Function 95-01(High insulation) is set, the “Standard setting” (00) will be the same
as “No correction” (01) [0.0°F (0.0°C)].

Room temperature control for wired remote controller sensor
Depending on the installed environment, correction of the wire remote temperature sensor
may be required.
Select the appropriate control setting according to the installed environment.
To change this setting, set Function 42 to Both “01”.
Ensure that the Thermo Sensor icon is displayed on the remote controller screen.
