Human Sensor Operation; Base Heater Operation; Peak Cut Operation - Fujitsu ASU30RLE Service Instruction

1-22. HUMAN SENSOR OPERATION

The HUMAN SENSOR functions by pressing SENSOR button on the remote controller.
When the sensor detects that there is no one in the room for 20 minutes or more,
it automatically changes the operation as below settings.
When someone comes back into the room, the human sensor will detect this, and
automatically revert to the original settings.

The sensor unit should detect when the human body (estimate: 150cmX30cm) or the object
which has more than 8 °F( 4°C) temp, difference from the background and are crossed
with1.0m/s speed in front of the sensor unit.

1-23. BASE HEATER OPERATION

The base heater is operated as shown in Fig. 13 .

When the compressor stops, Base heater is OFF.
When the outdoor fan motor stops, Base heater is OFF.
In the cooling mode, Base heater is OFF.
After defrost, it will turn OFF the heater (Comp Accumulated operation time) after 15 minutes.

1-24. PEAK CUT OPERATION

The Current Value is limited to reduce the power consumption by External Input.
During the PEAK CUT OPERATION , "CURRENT OVERLOAD OPERATION",
"ECONOMY OPERATION" and "LOW NOISE OPERATION" are effective,
and the outdoor unit operates by lowest current of them.
However, this function becomes invalid during DEFROST OPERATION.
