Heat Insulation Condition ( Building Insulation ); Thermo Control ( For Indoor Unit Sensor ); Thermo Control ( For Wired Remote Sensor ) - Fujitsu R410A Service Instruction

20

. HEAT INSULATION CONDITION ( BUILDING INSULATION )

This setting can make the room temperature control more suitable for homes or buildings
with high insulation (Function Number 95).
When the thermo sensor is turned ON it controls the compressor frequency at
initial start to prevent overshoot in heating or cooling.
21

. THERMO CONTROL ( FOR INDOOR UNIT SENSOR )

When room temperature is controlled by the Indoor unit sensor, compressor operation
is as shown in Fig. 10 and 11 .
But, adjustment is possible by the room temperature correction function setting.
(Function Number 30 or 31)

. THERMO CONTROL ( FOR WIRED REMOTE SENSOR )

When room temperature is controlled by the Wired remote sensor, compressor
operation is as shown in Fig. 12 and 13 .
But, adjustment is possible by the room temperature correction function setting.
