4.8 DISCHARGE TEMPERATURE CONTROL
Performed by A3 board
The following control is performed to prevent the discharge temperature from rising abnormally in order to protect
the inverter compressor. In accordance with the temperature of the discharge sensor TD, such controls are
performed as to limiting the increase of inverter frequency, decreasing it or halting operation of the compressor.
* If the discharge temperature exceeds 111°C (or 115°C for 257 & 307 units), operations of the compressor are
halted and then restarted 3 minutes later.
If this start/stop activity is repeated 4 times consecutively, the alarm "P03" (abnormal discharge temperature)
occurs.
