The other steps follow according to the ventilation curve. A step is
added each time a new stage is activated by the temperature controller.
Figure 2 below shows an example of this.

Stage 2
Stage 1
This example has two constant-speed ventilation stages. Step 1
corresponds to the activation of the first ventilation stage at
" temperature set point + differential 1 ". Step 2 corresponds to the
activation of the second ventilation stage at " temperature set point +
differential 1 + differential 2 ".
