Program 160 - Inserting two boilers into the heating system
Program 160: 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.
Feed pump A2 runs when:
 S5 is greater than the threshold min2  and S5 is greater than S3 by the difference diff2
 and S3 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 = S5 > (S3 + diff2) & S5 > min2 & S3 < 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)
All programs +2: The burner requirement (A3) is only admissible if pump A1 is switched off.
All programs +4 (only makes sense together with “all programs+2”): Feed pump A2 runs
when:
 S5 is greater than the threshold min2  and S5 is greater than S4 by the difference diff2

and S4 has not exceeded the threshold max2.
All programs +8 (additional sensor S6): If S6 exceeds the threshold max1 (no longer on
S2!) A3 (burner requirement) is switched off. The sensor S6 is fitted to the flue tube or can be
replaced with a flue-gas thermostat.
