Function and Control
3.11.1 Fully Closed with Power ON
Initialize the electronic expansion valve when turning on the power, set the opening position and
develop pressure equalizing.
3.11.2 Pressure Equalization Control
When the compressor is stopped, open and close the electronic expansion valve and develop
pressure equalization.
3.11.3 Opening Limit
Outline
Limit a maximum and minimum opening of the electronic expansion valve.
Detail
Maximum opening : 480 pulses
Minimum opening : 10 pulses
The electronic expansion valve is fully closed in the room where cooling is stopped and is opened
with fixed opening during defrosting.
3.11.4 Starting Operation Control
Control the electronic expansion valve opening when the system is starting, and prevent the
system from being super heated or producing condensation.
3.11.5 High Temperature of the Discharge Pipe
When the compressor is operating, if the discharge pipe temperature exceeds a certain value, open
the electronic expansion valve and remove the refrigerant from the low pressure side and lower
discharge temperature.
3.11.6 Disconnection of the
Discharge Pipe Thermistor
Outline
Disconnection of the discharge pipe thermistor is detected by comparing the discharge pipe
temperature with the heat exchanger temperature. If any are disconnected, open the electronic
expansion valve according to the outdoor air temperature and the operating frequency, operate for
9 minutes, and then stop.
After 3 minutes of waiting, the compressor restarts and the same process is carried out again. If the
disconnection is detected 4 times in succession, then the system will be shut down.
When the compressor runs for 60 minutes without any error, the error counter will reset itself.
Detail
Detect Disconnection
When the timer for open control (630 sec.) is over, and the 9-minute timer for the compressor
operation continuation is not counting time, the following adjustment must be made.
1. When the operation mode is cooling:
When the following condition is fulfilled, the discharge pipe thermistor disconnection is
ascertained.
Discharge pipe tempe10.8°F(+6°C) < outdoor heat exchanger temperature
2. When the operation mode is heating:
When the following condition is fulfilled, the discharge pipe thermistor disconnection is
ascertained.
Discharge pipe tempe10.8°F(+6°C) < indoor heat exchanger temperature
