measure actual pressure by a pressure gauge to adjust the output failure
Lack of refrigerant, charge additional refrigerant
and check if piping leaks, if yes, replace piping
check if high pressure is low,too
yes
check if piping is blocked
dredge piping
yes
replace pressure switch
low pressure abnormal
no
yes
check if the wiring between outdoor PCB and module is correct
compressor not start up, outdoor alarms, check if there is other failure
outdoor indicator flashes 22 times
yes
no
no
eliminate other failures
replace PCB
yes
if problem is solved
no
outdoor indicator flashes 24 times
adjust wiring
replace module
Alarm condition: outdoor system pressure is lower than 0.05MPa
no
yes
no
refrigerant charging amount is not appropriate,
recharging or remove some refrigerant
yes
repair 4-way valve
no
relpace outdoor PCB
check if the direction of 4-way valve is correct
clean indoor/outdoor heat exchanger
check if indoor evaporator or
outdoot condenser is too dirty
yes
check if the 4-way valve
port of PCB output 230V
check if outdoor pressure is normal
no
yes
outdoor failure lamp indicates 28
(12) 4-way valve reversing failure, systerm lack of refrigerant or discharging side dirty and blocked
Alarm condition: alarm and stop the unit when Td-Tci<=25 and lasts for 1 minute after the compressor has
started for 10 minutes check in heating mode, confirm the failure if it occurs 3 times in 1 hour
(13) systerm lack of refrigerant or discharging side dirty and blocked
Alarm condition: alarm and stop the unit when Td-Tci>=25 and lasts for 1 minute after the compressor
has started for 10 minutes in cooling mode, confirm the failure if it occurs 3 times in 1 hour
outdoor failure lamp indicates 29
check if outdoor pressure is normal
refrigerant charging amount is not appropriate,
recharging or remove some refrigerant
no
yes
check if indoor evaporator or
outdoot condenser is too dirty
yes
yes
clean indoor/outdoor heat exchanger
10) Communication failure between outdoor PCB and module
11) Outdoor low pressure abnormal
