Program 432: 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.
Output A3 switches on when S5 falls below threshold min3.
Output
A3 switches off (dominant) when S4 exceeds max3.
A1 = S1 > (S2 + diff1) & S1 > min1 & S2 < max1
A2 = S3 > (S4 + diff2) & S3 > min2 & S4 < max2
A3 (on) = S5 < min3 A3 (off) = S4 > max3
Program 433:
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 S2 by the difference diff2
and S2 has not exceeded the threshold max2.
Output A3 switches on when S5 falls below threshold min3.
Output
A3 switches off (dominant) when S4 exceeds max3.
A1 = S1 > (S2 + diff1) & S1 > min1 & S2 < max1
A2 = S3 > (S2 + diff2) & S3 > min2 & S2 < max2
A3 (on) = S5 < min3 A3 (off) = S4 > max3
All programs +2:
The burner requirement (A3) only occurs via sensor S5.
A3 (on) = S5 < min3 A3 (off) = S5 > max3 (dominant)
All programs+4: if sensor S2 has reached the threshold max1 pump A2 is activated and
pump
A1 continues running. A "cooling function" to the boiler or the heating is thereby
achieved without the occurrence of standstill temperatures at the collector.
All programs +8: An active solar circuit blocks the burner requirement. After switching off the
solar circuit the release of the requirement occurs with a delay of 5 minutes.
