10. PROCESSES AND FUNCTIONS

(4)Outdoor Fan Speed Control (CL1852) Low ambient fan speed control

This function protects the compressor from being damaged due to flowback of the liquid refrigerant to the compressor when the outdoor temperature is very low.

When the air temp. thermistor (TH) on the outdoor units detects a change in tem- perature, the controller on the electrical component box activates to control the fanspeed automatically.

If the outdoor temperature falls below 57°F, the fan speed switches to MED.

If the outdoor temperature falls below 30°F, the fan speed switches to LOW.
