2. Safety Features
Compressor three-minute delay at restart
Compressor functions 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.
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.
• If the unit is in heating mode, the indoor fan is
regulated by the anti-cold wind function.
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.
Low pressure check function(for some models)
The low pressure switch should be always closed. If it is
open, the air conditioner ceases operation until the fault is
cleared.
