f. INT69HBY control module and PTC temperature sensor
In order to protect compressor, each RC2 series compressor has been installed three PTC temperature sensors
inside motor coil and another one at the discharge side of compressor. These sensors are connected to an
INT69HBY control module to monitor the motor and discharge temperature. If the temperature in one of the positions
monitored exceeds the nominal response temperature of the respective PTC thermistor, the sensor resistance
increases and the INT69HBY control module output relay trips. The module resets when the temperature drops
below the response temperature by approx. 5K. The output replay provides a potentialfree changeover contact and
is energized as long as the nominal response temperature is not exceeded.
