Program 224 - Solar power system with 3 consumers
Program 224: 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.
Pump A3 runs when: S1 is greater than the threshold min1  and S1 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 = S1 > (S4 + diff3) & S1 > min1 & S4 < max3
Program 225: Instead of both pumps A1 and A2 one pump A1 and a three-way valve A2 are
deployed (pump - valve system between TK1 and TK2). Speed control: Observe the comments on
page 7!
A1 ... common pump A2 ... valve (A2/S receives power when filling tank TK2)
Program 226: Instead of both pumps A1 and A3 one pump A1 and a three-way valve A3 are
deployed (pump - valve system between TK1 and TK3). Speed control: Observe the comments on
page 7!
A1 ... common pump
A3 ... valve (A3/S receives power when filling tank TK3)
Program 227:
All three tanks are fed via one pump (A1) and two serially connected three-way valves (A2 and A3).
When both valves have no power, TK1 is fed. Speed control: Observe the comments on page 7!
A1 ... common pump
A2 ... valve (A2/S receives power when filling tank TK2)
A3 ... valve (A3/S receives power when filling tank TK3)
If there is an active priority allocation in menu VR, then the two valves A2 and A3 are never
switched on simultaneously: when filling into tank 2, only pump A1 and valve A2 are switched on,
when filling into tank 3, only pump A1 and valve A3 are switched on.
The priorities for TK1, TK2 and TK 3 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.
