2. Safety Features
Compressor three-minute delay at restart
Compressor functions are delayed for up to ten seconds
upon the first 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 nine seconds, the compressor ceases operation.
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 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 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 is
malfunctioning, the air conditioner ceases operation.
