7 outdoor fan speeds are determined for each model. 3 speeds for cool and dry modes, and 3speeds
for heat mode, and a very low speed.
Outdoor fan speed is a function of compressor frequency and outdoor air temperature (OAT).
4 routines for fan control are determined. The control routine selection depends on operation mode,
compressor speed, outdoor air temperature (OAT) and heat sink temperature (HST).
