The controller provides not only the correct speed for the outdoor fan, it also decides whether the fan should stop and for how long, to give an optimum control to the system. Furthermore the control avoids an overcondensing even with outdoor temperatures down to -20°C and no iced-up Indoor coils. Due to decreased compressor running time, a higher efficiency will be achieved.
