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 226F (108C) for
nine seconds, 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 appears 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 appears 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 operates after a period of setting time or when the louver is
in place.
• If the unit is in the 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
to operate and displays the corresponding error code, allowing for
emergency use.
• When more than one temperature sensor malfunctions, the air
conditioner ends the operation.
