1-9. ELECTRONIC EXPANSION VALVE CONTROL
The compressor won't enter operation status for 3 minutes after the compressor is stopped,
even if any operation is given.
1-10 PREVENT TO RESTART FOR 3 MINUTES ( 3 MINUTES ST )
01-11
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 speed, the temperatures detected by the discharge temperature sensor, the
indoor heat exchanger sensor
, the outdoor heat exchanger sensor
, and the outdoor temperature sensor.
Pulse range
70 ~ 500 pulse
(1) Pulse range of EEV
(2) The EEV is set up at 500 pulses when the compressor is stopped.
(3) Initialization (Input of 528 pulses toward closing direction) is operated under
the following condition.
* When the power is turned on.
* 4 hours has passed since the last initialization, and 3 minutes has passed after
the compressor stop.
(If 12 hours has passed since the last initialization, the compressor is compulsorily stopped.)

Operation
60 ~ 500 pulse
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.
(Table 8 : Operation contents memorized when the power is interrupted)
