ENGLISH
E1
Phase loss or neutral wire and live wire
are connected reversely (only for three
phase unit)
1.Check the power supply cables should be conneted stable,aviod phase loss.
2.Check whether the sequence of neutral wire and live wire are connected reversely
E5
The condenser outlet refrigerant tempe-
rature sensor (T3) error
1. The T3 sensor connector is loosen. Reconnect it.
2. The T3 sensor connector is wet or there is water in. remove the water, make the
connector dry. Add waterproof adhesive.
3. The T3 sensor failure, change a new sensor
E6
The ambient temperature sensor (T4)
error
1. The T4 sensor connector is loosen. Reconnect it.
2. The T4 sensor connector is wet or there is water in. remove the water, make the
connector dry. Add waterproof adhesive.
3. The T4 sensor failure, change a new sensor.
E9
Suction temperature sensor (Th) error
1.The Th sensor connector is loosen. Re connect it.
2.The Th sensor connector is wet or there is water in. remove the
water, make the connector dry. Add waterproof adhesive.
3. The Th sensor failure, change a new sensor.
EA
Discharge temperature sensor (Tp) error
1. wire doesn’t connect between main control board PCB B and main control board
of hydraulic module. connect the wire.
2. Communication wire sequence is not right. Reconnect the wire in the right sequen-
ce.
3. Whether there is a high magnetic field or high power interfere, such as lifts, large
power transformers, etc.. To add a barrier to protect the unit or to move the unit
to the other place.
H0
Communication fault between main
board PCB B and main control board of
hydraulic module
.1 wire doesn’t connect between main control board PCB B and main control board
of hydraulic module. connect the wire.
2. Communication wire sequence is not right. Reconnect the wire in the right sequen-
ce.
3. Whether there is a high magnetic field or high power interfere, such as lifts, large
power transformers, etc.. To add a barrier to protect the unit or to move the unit
to the other place.
H1
Communication error between inverter
module PCB A and main control board
PCB B
1. Whether there is power connected to the PCB and driven board. Check the inverter
module PCB indicator light is on or off. If Light is off, reconnect the power supply
wire.
2. if light is on, check the wire connection between inverter module PCB and main
control board PCB, if the wire loosen or broken, reconnect the wire or change a
new wire
H4
Three times P6 (L0/L1) protect
The sum of the number of times L0 and L1 appear in an hour equals three.See L0 and
L1 for fault handling methods
H6
The DC fan failure
1. Strong wind or typhoon below toward to the fan, to make the fan running in the
opposite direction. Change the unit direction or make shelter to avoid typhoon
below to the fan.
2. fan motor is broken, change a new fan motor.
H7
Voltage protection
1. Whether the power supply input is in the available range.
2. Power off and power on for several times rapidly in short time. Remain the unit
power off for more than 3 minutes than power on.
3. the circuit defect part of Main control board is defective. Replace a new Main PCB.
H8
Pressure sensor failure
1. Pressure sensor connector is loosen, reconnect it.
2. Pressure sensor failure. change a new sensor.
HF
Suction temperature sensor (Th) error
1. The EEprom parameter is error, rewrite the EEprom data.
2. EEprom chip part is broken, change a new EEprom chip part.
3. Inverter module board is broken, change a new PCB.
