Control Specification
SiBE04-824
42
Function and Control
3.11.1 Fully Closing 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
A maximum electronic expansion valve opening : 480 pulses
A minimum electronic expansion valve opening : 52 pulses (25/35 class), 54 pulses (50 class)
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 to be super heated or moistened.
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 to 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 is disconnected, open the electronic
expansion valve according to the outdoor air temperature and the operating frequency, and
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 5 times (25/35 class) or 4 times (50 class) in succession, then the
system will be 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 (25/35 class : 810 sec., 50 class : 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 tempe6°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 tempe6°C < indoor heat exchanger temperature
