5  Equations 16 and 17—calculating part load compensation factor for controller of fan, CC,i
 (1) For equation 12, if paragraph (a) of the definition of CC,i is applicable, CC,i is worked out using the equation (equation 16):

 (2) For equation 12, if paragraph (b) of the definition of CC,i is applicable, CC,i is worked out using the equation (equation 17):

 (3) For this section, for fan i:
ai is a regression coefficient, and is:
 (a) if the motor input power (PE,i) of the fan is less than 5 kilowatts—0.030; and
 (b) otherwise—0.
ln(PE,i­) is the natural log of the motor input power (PE,i), in kilowatts, of the fan.
PE,i is the motor input power, in kilowatts, of the fan, and is:
 (a) if the model of the fan was tested with the same drive, motor and transmission as the fan—the motor input power of the fan in kilowatts, as referred to in subsection 3(1) of this Schedule; and
 (b) otherwise—the motor input power of the fan in kilowatts, as referred to in subsection 3(2) of this Schedule.
bi is a regression constant, and is:
 (a) if the motor input power (PE,i) of the fan is less than 5 kilowatts—1.088; and
 (b) otherwise—1.04.
