Program 528 – 2 independent differential circuits & independent burner request
Program 528: Pump A1 runs, if:
• S1 exceeds the threshold min1 • and S1 is greater than S2 by the difference diff1
• and S2 has not exceeded the threshold max1 .
Pump A2 runs, if:
• S3 exceeds the threshold min2 • and S3 is greater than S4 by the difference diff2
• and S4 has not exceeded the threshold max2 .
Output A3 is activated, if S6 falls below the threshold min3 .
Output A3 is deactivated (dominantly), if S5 exceeds the threshold max3 .
A1 = S1 > (S2 + diff1) & S1 > min1 & S2 < max1
A2 = S3 > (S4 + diff2) & S3 > min2 & S4 < max2
A3 (on) = S6 < min3 A3 (off) = S5 > max3
All pr1: The burner request ( A3 ) is regulated only via sensor S6 (deactivation dom -
inant).
A3 (on) = S6 < min3 A3 (off) = S6 > max3
necessary settings:
max1
max2
max3
