Compressor three-minute delay at restart
Compressor functions are delayed for up to ten seconds upon the fi rst startup of the unit, and are delayed for up
to three minutes upon subsequent unit restarts.
Automatic shutoff based on discharge temperature
If the compressor discharge temperature exceeds a certain level for a period of time, the compressor ceases operation.
Automatic shutoff based on fan speed
If the indoor fan speed registers below 200RPM or over 2100RPM for an extended period of time, the unit ceases
operation and the corresponding error code is displayed on the indoor unit.

The inverter module has an automatic shutoff mechanism based on the unit’s current, voltage, and temperature. If
automatic shutoff is initiated, the corresponding error code is displayed on the indoor unit and the unit ceases operation.
Indoor fan delayed operation
• When the unit starts, the louver is automatically activated and the indoor fan will operate after a period of setting
time or the louver is in place.
• If the unit is in heating mode, the indoor fan is regulated by the anti-cold wind function.

• If one temperature sensor malfunctions, the air conditioner continues operation and displays the corresponding error
code, allowing for emergency use.
