721

InUnit Clock
Abnormal
Alarm

The clock circuit of the main
control board of the indoor unit
is faulty.

Replace the main control board
of the indoor unit.

722

Smoke Sensor
Power Alarm

The voltage of the smoke
sensor circuit of the main
control board of the indoor unit
exceeds the preset threshold.

723

Evaporator
Coils Temp
Invalid

The temperature sensor
cable is not properly
connected.

The temperature sensor is
faulty.

Check the cable connection
to the temperature sensor.

Maintain or replace the
temperature sensor.

801

Return Air
High Temp
Alarm

The heat load is high, or the
cooling capacity is
insufficient.

The return air temperature is
high shortly after the unit is
started.

The ambient temperature
exceeds the upper threshold.

The return air high
temperature alarm threshold
is inappropriate for the
working conditions.

The temperature displayed
by the temperature sensor is
different from the actual
temperature.

Add smart cooling products.

Check whether other causes
exist if the alarm is not
cleared in a long time after
startup.

Check the ambient
temperature.

Adjust the return air high
temperature alarm threshold.

Calibrate or replace the
temperature sensor.

802

Return Air
Low Temp
Alarm

The heat load is low or the
cooling capacity is too high.

The ambient temperature is
too low.

The return air low
temperature alarm threshold
is inappropriate for the
working conditions.

The temperature displayed
by the temperature sensor is
different from the actual
temperature.

Reduce the number of smart
cooling products.

Check the ambient
temperature.

Adjust the return air low
temperature alarm threshold.

Calibrate or replace the
temperature sensor.
