Program 80: 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.
A1 = S1 > (S2 + diff1) & S1 > min1 & S2 < max1
A2 = S3 > (S4 + diff2) & S3 > min2 & S4 < max2
Program 81 (all programs +1):
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.
A2 = S3 > (S2 + diff2) & S3 > min2 & S2 < max2
All programs +2:
If sensor S2 has reached max1 (or if S4 has reached threshold max3 along with all programs +4),
pump A2 is switched on, and pump A1 keeps running. This provides a cooling function for the boiler /
heater without causing standstill temperatures in the collector.
All programs +4:
In addition, if S4 exceeds the threshold max3, pump A1 is switched off.
All programs +8: With re-cooling activated (all progr. +2) A3 runs concurrently.
