Note: When replacing the controller, make sure insert the wire jumper into the new controller, otherwise the
unit will display C5
The breaker trips at once when it
is set to "ON".
Measure insulation resistance
to ground to see if there is any
leakage.

The circuit or the part of the air conditioner has
malfunction. They heat and break the insulation
and lead to short circuit or creepage. Measure
the insulation resistance or eliminate the mal-
function one by one. If the breaker itself has
malfunction, then replace the breaker.
Check the voltage. If it is lower than 10% of the
rated voltage, check the cause, improve the power
supply condition and add the stabilized voltage
power supply.
First, press the manual switch button
AUTO, if there is no response,check
based on the above methods. If it runs
normally after pressing the button,
check again whether the installation
position and the connection wire
of the reception head is correct. If it is
correct,then replace the receiver or the
remote controller.
The transformer connection is loose or
has bad contact or the transformer
has malfunction
Fasten the wiring; measure the
output voltage of the transformer, if
it is incorrect, change the
transformer
The air condition-
er does not react
after it is power-
ed ( after the plug
is inserted,
the buzzer does
not sound and
the remote star-
tup has
no response)
The remote con-
troller does not
receive signals
(after it is
powered, the
buzzer will
sound, unless it
has malfunction)
