Function and Control
3.2.15 Discharge Pipe Temperature Protection Control
Electronic expansion valve opening degree and the compressor operating frequency will be
controlled in order to avoid abnormal high compressor temperatures.
Td: Discharge pipe temperature
Compressor Operating Frequency Control
Electronic Expansion Valve Opening Degree Control
Td: Compressor discharge pipe temperature (°C)
3.2.16 Capacitor Electric Discharge Control
After the operation stopped (the stop caused by the remote controller, an error, and the
compressor and outdoor unit fan motor when retry thermo. is off), open phase waveform is
output for about one minute for electric discharge of the capacitor.
Afterwards, electric discharge will continue due to discharge resistance until the capacitor
voltage becomes 0 V. At this time, operation sound may be heard from the outdoor unit.
