Blizzard Turbo Split System Manual
To adjust low fan speed:
While in OFF mode, enter programming mode by pressing the MODE and minus (-) keys for three seconds. The display will
flash "PO" during the three seconds. After the three-second flash, a flashing 1 will appear on the display, which is function #1.
While in program mode, the OFF LED will flash, which indicates program mode. Scroll through the function numbers by
pressing the plus (+) or minus (-) key until #5 is displayed. Press the MODE key and the current value is displayed. The low fan
LED will flash. Factory default is 38. Range is 2 to 57. Use the plus (+) or minus (-) key to change value and then, press the fan
key once to save information and continue programming or press the fan key twice to save and exit program mode.
NOTE: For most efficient operation of your system, you should normally keep the low fan speed at the highest
possible setting consistent with a comfortable noise level. Running the fan speed too slow can damage the
compressor.
