3) For AER522SCL3 only (3 phase and low ambient version)
• When the outside ambient temperature decreases, the rotation speed of the outdoor fan is regulated by
means of the outdoor heat-exchanger sensor to prevent liquid back.
• The rotation speed varies with indoor temperature conditions (Hatching area).
• The unit is protected against high pressure by means of the outside temperature sensor, and thus when
the outside ambient temperature reaches 30
° C respectively, the fan speed is forced to high.
