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 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, 35, 36) will reset to “No correction” [0.0°F
(0.0°C)].
