Program 576 - Cascade: S4  S1  S2 + burner requirement
Program 576: Feed 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:
 S4 is greater than the threshold min2  and S4 is greater than S1 by the difference diff2

and S1 has not exceeded the threshold max2.
Output A3 switches on when S4 falls below threshold min3.
Output
A3 switches off (dominant) when S3 exceeds max3.
A1 = S1 > (S2 + diff1) & S1 > min1 & S2 < max1
A2 = S4 > (S1 + diff2) & S4 > min2 & S1 < max2
A3 (on) = S4 < min3 A3 (off) = S3 > max3
All programs +1:
The burner requirement (A3) only occurs via sensor S4.
A3 (on) = S4 < min3 A3 (off) = S4 > max3 (dominant)
Required settings:
max1 … limit CYL 3 S2  A1
max2 … limit CYL 2 S1  A2
max3 … burner req. off CYL 1 S3  A3
min1 … switch-on temp. CYL 2 S1  A1
min2 … switch-on temp. CYL 1 S4  A2
min3 … burner req. on CYL 1 S4
 A3
diff1 … CYL 2 S1 – CYL 3 S2  A1
