Note: In the above table, the actual value of the electronic expansion valve and
the air speed is 10 times of the parameter displayed value. For example, when the
P20 defrost expansion valve opening degree shows 30, the actual value at this time is
300 steps; when P30 fan manual rotation speed shows 80, the actual value at this
time is 800. When the value is more than 100, A represents for 10, B represents for 11,
C represents for 12, and D represents for 13.

Solutions
Er 03
water flow failure
Check water flow /switch
Er 04
winter anti-freezing
Water pump will run automatically
for first grade antifreeze
Er 05
high pressure failure
1. Discharge redundant
refrigerant from heat pump gas
system
2.Clean the water exchanger or
water fifter
Er 06
low pressure failure
1.Check if there is any gas
leakage ,re-fill the refrigerant
2.Replace the filter or capillary
Er 09
communication failure between Display
and PCB
1. Check if the communication
connection wire between display
and PCB is disconnected or has
poor contact. Change the wire or
