All models are provided with a High Pressure Sensor to monitor the condensing
temperature. If the high-side pressure rises to operate the High Pressure Sensor, the
Compressor will not restart for at least 6 minutes to protect itself.
HFE series is also equipped with a backup High Pressure Switch. If the Condensing
Temperature Thermistor becomes defective, the High Pressure Switch operates to stop
and protect the Compressor.
