Suction
Temperature
Sensor
The outdoor heat exchanger thermistor is used for controlling target discharge temperature.
The system sets a target discharge temperature according to the outdoor and indoor heat
exchanger temperature, and controls the electronic expansion valve opening so that the
target discharge temperature can be obtained.
Exhaust
Temperature
Sensor
The discharge pipe thermistor is used for controlling temperature of the discharge pipe.
If the temperature of discharge pipe (used in place of the inner temperature of the
compressor) rises abnormally, the operating frequency drops or the operation halts.
Indoor heat-

Sensor
1.The indoor heat exchanger thermistor is used for controlling target discharge
temperature.
The system sets a target discharge temperature according to the outdoor and indoor heat
exchanger temperature, and controls the electronic expansion valve opening so that the
target discharge temperature can be obtained.
2.The indoor heat exchanger thermistor is used for preventing freezing.During the cooling
operation, if the temperature drops abnormally, the operating frequency becomes lower,
then the operation halts.
3.The indoor heat exchanger thermistor is used for anti-icing control.During the cooling
operation, if the heat exchanger temperature in the room where operation is halted
becomes -1°C, it is assumed as icing.
