when turned on /off

Check if the power is connected properly to
RV


off

Check if the power has good connection
from roof unit to plenum
2.
Cooling not good

Select correct cooling mode and confirm
light is showing

The set temperature should be lower than
room temperature

There is three minutes delay on compressor

Make sure filters are clean

Select max fan to achieve best performance

Be sure all door and windows are closed

Draw curtains to help reduce incoming
heat
3.
Heating not good

Select correct heating mode and confirm
light is showing

The set temperature should be higher than
room temperature

There is three minutes delay on
compressor

It needs more time to start heating on an
extremely cold winter day

Make sure filters are clean

Select max fan to achieve best

Curtains should help to introduce cold air
in
E0 Communication fault
E1 Room temperature sensor
Fault in connection to temperature sensor or other damage.
E2 Indoor coil temperature sensor
Fault in connection to temperature sensor or other damage.
E3 Outdoor coil temperature sensor
Fault in connection to temperature sensor or other damage.
E4 Insufficient refrigerant
Capillary tube fracture leads to coolants leakage, compressor fault or sensor failure.
E5 Temperature anomaly-outdoor coil
Temperature too high when cooling or too low when heating. (When cooling, the display of E5 indicates
the outdoor temperature exceeds 68
℃
. It is likely due to the reduction of air flow of the condenser,
poor working of condenser fan or sensor failure; when heating, if the outdoor temperature is higher
than 18
℃
, the external air blower may rotate between on and off. The occurrence of this is not a fault,
but the self-protection of the system for avoiding overheating of the unit.)
