Program 544 - Cascade: S1  S2  S3  S4
Program 544:
Solar 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:
 S2 is greater than the threshold min2  and S2 is greater than S3 by the difference diff2
 and S3 has not exceeded the threshold max2.
The feed pump A3 runs when:
 S3 is greater than the threshold min3  and S3 is greater than S4 by the difference diff3
 and S4 has not exceeded the threshold max3.
A1 = S1 > (S2 + diff1) & S1 > min1 & S2 < max1
A2 = S2 > (S3 + diff2) & S2 > min2 & S3 < max2
A3 = S3 > (S4 + diff3) & S3 > min3 & S4 < max3
Required settings:
max1 … limit CYL 1 S2  A1
max2 … limit CYL 2 S3  A2
max3 … limit CYL 3 S4  A3
min1 … switch-on temp. coll S1  A1
min2 … switch-on temp. CYL 1 S2  A2
min3 … switch-on temp. CYL 2 S3  A3
diff1 … coll. S1 – CYL 1 S2  A1
diff2 … CYL 1 S2 – CYL 2 S3  A2
diff3 … CYL 2 S3 – CYL 3 S4  A3
