Program 560 - Cascade: S1  S2 / S3  S4  S5
Program 560: Pump A1 runs when:
 S1 is greater than the threshold min1  and S1 is greater than S2 by the difference diff1
 and S2 has not exceeded the threshold max1.
The feed pump A2 runs when:
 S3 is greater than the threshold min2  and S3 is greater than S4 by the difference diff2

and S4 has not exceeded the threshold max2.
The feed pump A3 runs when:
 S4 is greater than the threshold min3  and S4 is greater than S5 by the difference diff3

and S5 has not exceeded the threshold max3.
A1 = S1 > (S2 + diff1) & S1 > min1 & S2 < max1
A2 = S3 > (S4 + diff2) & S3 > min2 & S4 < max2
A3 = S4 > (S5 + diff3) & S4 > min3 & S5 < max3
All programs +1: The pump A3 runs if:
 S3 is greater than threshold min2  and S3 is higher than S5 by the difference diff3
 and S5 has not exceeded threshold max3
or

S4 is greater than threshold min3  and S4 is higher than S5 by the difference diff3

and S5 has not exceeded threshold max3
A3 = (S3 > (S5 + diff3) & S3 > min2 & S5 < max3)
or (S4 > (S5 + diff3) & S4 > min3 & S5 < max3)
