Solution
Water inlet temp. Sensor failure
P01
The water inlet temp. Sensor is
open or shortcircuit
Check or change thewater
inlet temp. Sensor
Water outlet temp. Sensor failure
P02
The water outlet temp. sensor is
open or shortcircuit
Check or change thewater
outlet temp. Sensor
Ambient temp. Sensor failure
P04
The ambient temp. sensor is
open or shortcircuit
Check or change the
ambient temp. Sensor
Pipe temp. Sensor failure
P05
The pipe temp. sensor is
open or short circuit
Check or change thepipe temp. Sensor
Evaporator temp.Sensor failure
P07
The evaporator temp. Sensor is
open or shortcircuit
Check or change the
evaporator temp. Sensor
High pressure protect
E01
The exhaust pressure ishigh ,
high pressure switch action
Check high pressure switch
and cooling return circuit
Low pressure protect
E02
The suction pressure islow,
Low pressure switch action
Check low pressure switchand
cooling return circuit
Flow switch failure
E03
No water or litterwater in
water system
Check the flow volume,water
pump is failure ornot
Temp. istoo much different
between water-inlet and outlet
E06
Water flow volume not enough,
Water system pressure difference is small
Check the flow volume,water
system is jammed ornot
Antifreezing under cooling mode
E07
Water flow volume not enough
Check the flow volume,water
system is jammed ornot
The primary anti-freezing
protection start.
E19
Ambient temperature is toolow
The second anti-freezing
protection start
E29
Ambient temperature is toolow
Communication failure
E08
Communication failure between remote
wire controller andmain board
Check the wire connection between
remote wire controller andmain board
