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.
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, tank 2 is filled by priority.
A1 ... common pump
All programs +2: When both tanks 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 tank TK1 is made via the independent sensor S6 and the maximum
threshold max1 (no more maximum threshold on S2)
The priorities for TK1 and TK2 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.
