〖Protect Functions〗
Protect functions can prolong the air conditioner’ s service life and provide more comfortable airflow.
Delay-starting protection for the compressor
The compressor will restart working at least 3 minutes (5 minutes in heating mode) after being turned off
to keep the pressure balance of the cooling system.
Remarks: There will be 1 minute for the compressor to work after the unit is electrified for the first time.
Defrosting (not available for cooling-only type air conditioner)
The outdoor heat exchanger may frost if the outdoor temperature is low and humidity is high. In this
case, auto-defrosting has operated for 3~10 minutes. pause indicator(red) will be on, indoor and
outdoor fan stop.
Heating overload protection (not available for cooling-only type air conditioner)
When the temperature of indoor pipe is too high, air conditioner enters heating overload protection. And
indoor fan speed should be adjusted to a higher gear automatically. Outdoor fan and compressor may
be stopped. When indoor pipe temperature drops to a rated value, air conditioner will exit heating
overload protection. Indoor fan motor resumes to the normal status.
Blowing residual heat function (not available for cooling-only type air conditioner)
Indoor fan will keep running at low fan speed for 80 second when air conditioner is stopped in heating
mode.
Cooling airflow proof (not available for cooling-only type air conditioner)
In the first several minutes of heating operation, PAUSE indicator lights; indoor fan doesn’t run and
louver blades can not be controlled. About 5 minutes later, air conditioner will blow heat airflow, PAUSE
indicator is off.
Freeze-prevention
To prevent indoor heat exchanger freezing in cooling and dehumidification operation, compressor or
outdoor fan may stop running; indoor fan speed will be adjusted to a higher gear automatically.
Dry for enzyme-prevention
Indoor fan motor will go on running for 3 minutes at low fan speed when turned off in cooling mode in order to
keep dry condition inside the unit.
Auto restart (optional)
The unit memories the operation mode, air flow setting, temperature setting etc., so that should there be
a power failure when the unit is in operation, it will automatically return the same operating conditions
when the power is restored.
