max1 max2
Program 176: 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.
Pump A2 runs when:
 S1 is greater than the threshold min1  and S1 is greater than S3 by the difference diff2
 and S3 has not exceeded the threshold max2.
The feed pump A3 runs when:
 S5 is greater than the threshold min2  and S5 is greater than S4 by the difference diff3
 and S4 has not exceeded the threshold max3.
A1 = S1 > (S2 + diff1) & S1 > min1 & S2 < max1
A2 = S1 > (S3 + diff2) & S1 > min1 & S3 < max2
A3 = S5 > (S4 + diff3) & S5 > min2 & S4 < max3
All programs +1: Instead of both pumps A1 and A2 one pump A1 and a three-way valve A2 are
deployed. Speed control: Observe the comments on page 7!
Without a priority allocation, cylinder 2 is filled by priority.
A1 ... common pump
All programs +2: When both cylinders have reached their maximum temperature via the solar
system, the pumps A1 and A3 are switched on (re-cooling function).
All programs +4: Both solar circuits have separate switch-on thresholds on S1.
The output A1 continues to retain min1 and A2 switches with min3.
All programs +8: The limiting of cylinder CYL 1 is made via the independent sensor S6 and the
maximum threshold max1 (no more maximum threshold on S2)
The priorities for CYL 1 and CYL 2 can be set in the parameter menu under PA. In addition, a solar
priority function can be set for this diagram in the menu PRIOR.
