5.2. Temperature correction
NOTES:
When changing Function 95, perform this setting before other Room temp. control settings
(Function 30, 31, 35, 36).
If Function 95 is not set fi rst, Room temperature control settings (Function 30, 31, 35, 36)
will be reset and you must re-do them again.
■
Heat Insulation condition (building insulation)
Heat insulation conditions diff er 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, 35, 36) 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 of the room temperature sensor is corrected as follows:
Corrected temp. = Temp. of room temp. sensor - correction temp. value
Example of correction :
When the temperature of room temp. sensor is 78 °F and the setting value is
“03” (-2 °F), the corrected temp. will be 80 °F (78 °F [-2 °F]).
The temperature correction values show the diff erence from the “Standard setting” (00)
(manufacturer’s recommended value).
