Program 48: 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.
All programs +1:
Instead of the two pumps, one pump and a three-way valve are used (pump-valve system). Speed
control: Observe the comments on page 7!
Without a priority allocation, tank 2 is filled by priority.
A1 ... common pump
All programs +2:
In addition, if S4 exceeds the threshold max3, pump A1 is switched off.
All programs +4: Both solar loops have separate switch-on thresholds at S1:
output A1 retains min1, and A2 switches at min2.
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.
