Safety Features
Compressor Three-Minute Delay at Restart
Compressor functions are delayed for up to ten seconds upon the
first start-up 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 226F (108C)
for nine seconds, the compressor ceases operation.
Automatic shutoff based on fan speed
If the indoor fan speed registers below 300RPM or over 1500RPM
for an extended period of time, the unit ceases operation and the
corresponding error code is displayed on the indoor unit.
Inverter module protection
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 when the
louver is in place.
• If the unit is in HEATING mode, the indoor fan is regulated by the
anti-cold wind function.
Compressor Preheating
Preheating is automatically activated when the T4 sensor is lower than
setting temperature.
Sensor redundancy and automatic shutoff
• If one temperature sensor malfunctions, the air conditioner
continues operation and displays the corresponding error code,
allowing for emergency use.
• When more than one temperature sensor malfunctions, the air
conditioner ceases operation.
