1-8. Setting the 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)].
‡
Temperature Correction
When changing Function 95, perform this setting before other Room temp.
control settings (Function 30, 31, 92, 93).
If Function 95 is not set fi rst, Room temperature control settings (Function 30, 31, 92, 93)
ill be reset and you must re-do them again.
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)].
