Fujitsu AOU36RLX Service Instruction

10. ELECTRONIC EXPANSION VALVE CONTROL
The most proper opening of the electronic expansion valve is calculated and controlled under the
present operating condition based on the following values.
The compressor frequency, the temperatures detected by the discharge temperature sensor
and the outdoor temperature sensor.
The pulse range of the electronic expansion valve control is between 50 to 480 pulses.
At the time of supplying the power to the outdoor unit, the initialization of the electronic
expansion valve is operated (1000 pulses are input to the closing direction).
11. TEST OPERATION CONTROL
Under the condition where the air conditioner stops, press the MASTER CONTROL button and
the FAN CONTROL button simultaneously for 5 seconds or more, and the test operation control
mode will appear.
During test running, " " will display on the remote controller display.
Set the test operation mode, and the compressor will continue to run regardless of whatever
the room temperature sensor detects.
The test operation mode is released if 60 minutes have passed after setting up the test operation.
The compressor won't enter operation status for 3 minutes after the compressor is stopped,
even if any operation is given.
At the time when the air conditioner is switched from the cooling mode to heating mode,
the compressor is stopped, and the 4-way valve is switched in 3 minutes later
after the compressor stopped.
When the power was interrupted by a power failure, etc. during operation, the operation contents
at that time are memorized and when power is recovered, operation is automatically resumed with
the memorized operation contents.
When the power is interrupted and recovered during timer operation, timer operation is canceled,
but only setting time is memorized.

Under the condition where the air conditioner runs, short two metal contacts under the battery
compartment lid, and the test operation control mode will appear.
During test running, the operation lamp and timer lamp of the air conditioner body twinkle simultaneously.
Set the test operation mode, and the compressor will continue to run regardless of whether the room
temperature sensor detects.
The test operation mode is released if 60 minutes have passed after setting up the test operation.
