10.4.12 High work-intense protection

Outdoor display LED1 flash 21 times

Method of High work-intense control is activated in the heating mode if the temperature

Malfunction being sensed by the heat exchanger thermistor exceeds the limit.

Detection

Malfunction Activated when the temperature being sensed by the heat exchanger

Decision rises above 65 .

Conditions

Supposed

Faulty electronic expansion valve

Causes

Dirty heat exchanger

Faulty heat-exchange sensor

Insufficient gas

Troubleshooting * Caution Be sure to turn off power switch before connect or disconnect connector, or

else parts damage may be occurred.

Electrify the machine again and turn it on with the

remote controller, check whether the wind

temperature is below 65

The malfunction is reported

after the machine has run

for some time?

Check room temperature and

pipe temperature sensor.

2 the temperature monitoring circuit

of the indoor mainboard

The indoor unit blows poorly

due to blocked filters or poor

condition of the fan?

1) Clean the filters

2) Reinstall the fan.

Use some tools to measure the pressure of system

YES

Service diagnosis
