Symptom

Possible cause

Solution

The LED indicator of the unit

displays ER16 and the wired

controller displays 16

Overload of compressor or

fan in #1

1. Over current of the

compressor #1, the overload

protector triggered.

1. Check whether the

electric current parameter

of the overload protector

is configured correctly by

referring to the electric circuit.
2. Check whether the

resistor of the malfunctioned

compressor meets

specification requirements.

2. Over current of the fan

#1, the overload protector

triggered.

1. Check whether the

electric current parameter

of the overload protector

is configured correctly by

referring to the electric circuit.
2. Check whether the

resistor of the malfunctioned

fan meets specification

requirements.

The LED indicator of the unit

displays ER17 and the wired

controller displays 17

Overload of compressor or

fan in #2

1. Over current of the

compressor #2, the overload

protector triggered.

1. Check whether the

electric current parameter

of the overload protector

is configured correctly by

referring to the electric circuit.
2. Check whether the

resistor of the malfunctioned

compressor meets

specification requirements.

2. Over current of the fan

#2, the overload protector

triggered.

1. Check whether the

electric current parameter

of the overload protector

is configured correctly by

referring to the electric circuit.
2. Check whether the

resistor of the malfunctioned

fan meets specification

requirements.

The LED indicator of the unit

displays ER18 and the wired

controller displays 18

Overload of pump

Over current in the pump

has triggered the overload

protector.

1. Check whether the electric

current parameter of the

overload pump is configured

correctly by referring to the

electric circuit.

2. Check whether the

resistor of the malfunctioned

pump meets specification

requirements.

The LED indicator of the unit

displays ER19 and the wired

controller displays 19

Lack of water flow

1. Pump is too small

Replace the pump

2. Blocked of water filter

Clean water filter

3. Air inside water system

Discharge air by opening the

pump

4. Water pressure drop to

large, water system is not

balance

Optimize the water system

5. Blocked of other parts in

water system

Check and repair
