Discharge Pipe Control

Outline

With the internal compressor temperature used as a substitute of the discharge pipe
temperature, when the
discharge pipe temperature exceeds the specified level, the discharge pipe control regulates
the upper limit of the output frequency to prevent the internal pressure from rising.
(This function serves the same purpose as the discharge pipe high temperature control that
regulates the motorized valve.)

Details

With each operation of the discharge pipe temperature malfunction operation counter, the
above zone judgment temperature is decreased by 2.5°C.
