h. INT69 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 INT69
control module to monitor the motor coil temperature and discharge temperature as well. 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 INT69 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.
