d. INT69HBY motor protector and PTC temperature sensor
In order to protect compressors, every RC2-AV series compressor has four PTC temperature sensors (thermistors),
three embedded in motor coil and one at the discharge port of the compressor. These sensors are connected to
INT69HBY protection module to monitor the motor coil temperature and discharge temperature. If the temperature in
one of the positions monitored exceeds the target temperature (for standard PTC thermistor: 110
o
C), the sensor
resistance increases dramatically and the protector INT69HBY output relay trips.
