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 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.

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)
