Name
Used to detect liquid pipe temperature of air heat exchanger. Used
to make judgements on defrost operation.
This detects temperature of gas pipe for air heat exchanger.
Used to detect discharge pipe temperature.
Detects compressor surface temperature, this switch is activated at
surface temperature of 120°C (248°F) or more to stop the
compressor.
Used to detect discharge pipe temperature.
Detects compressor surface temperature, this switch is activated at
surface temperature of 120°C (248°F) or more to stop the
compressor.
Detects the air temperature inside the electrical component box.
