Program 80 - Single solar power system and cylinder load from boiler
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):
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.
