Discharge Temperature Sensor (Td)
The temperature of the compressor discharge hot gas will
be monitored by the Discharge Temperature Sensor. If the
sensor reads too hot or cool, the frequency/status of the
operation will be adjusted as needed.
The hot gas will leave the oil separator and enter the 4-way
valve. The 4-way valve will direct the hot gas to ALL of the
indoor coils.
Note: Any indoor unit that is in heating mode will have it’s
louver open and indoor fan running. Non-calling indoor
units will receive hot gas but their fans will remain on
very low speed with the louver open. When demand for
heat increases, the indoor fan will speed up to meet the
increased demand.

Gas Pipe Temperature Sensor (Tc1) & Indoor Heat
Exchanger Temperature Sensor (Toci)
The temperature of Tc1 should now be hot. This will indicate
the 4-way valve is directing hot gas to the indoor coils. The
PCB will detect the temperature dierence and generate an
Error Code.
The indoor heat exchanger temperature sensor will
monitor the temperature of the indoor coil to ensure it is
hot enough to prevent blowing cold air. Once adequately
warm temperature is sensed at the indoor coil, the PCB will
increase the fan speed if needed to meet the demand.
The hot gas entering the indoor coil will condense into a
saturated mix and then be subcooled. The refrigerant will
return to the outdoor unit via the liquid line.
3
Liquid Pipe Temperature Sensor (Tc2)
This sensor monitors the temperature of the refrigerant liq-
uid returning from the indoor coil. The indoor EEV opening
angle is adjusted according to the degree of superheat.
As the outdoor coil absorbs heat from the surrounding
air, the very cold liquid refrigerant is changed to a cool
vapor. This vapor travels through the 4-way valve to the
accumulator.
4
Defrost Temperature Sensor (Te)
The outdoor coil temperature will be sensed by the Defrost
Sensor. The sensor will use this temperature to to adjust
EEV open angle and to calculate when a defrost cycle is
necessary.
5
Suction Temperature Sensor (Ts)
The temperature of the suction gas entering the
compressor is monitored by the Suction Temperature
Sensor.
As the demand becomes less while the indoor temperature
rises toward the desired temperature, the compressor will
reduce speed. When the set temperature is reached, the
compressor and outdoor fan will shut o. The circulating fan
of each indoor unit continues to run.
