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 CYL 1 and CYL 2).
Speed control: Observe the
comments on page 9!
A1 ... common pump A2 ... Valve (A2/S receives power when filling cylinder CYL 2)
Program 226: Instead of both pumps A1 and A3 one pump A1 and a three-way valve A3 are
deployed. (pump - valve system between CYL 1 and CYL 3).
Speed control: Observe the
comments on page 9!
A1 ... common pump A3 ... Valve (A3/S receives power when filling cylinder CYL 3)
Program 227: All three cylinders are fed via one pump (A1) and two serially connected
three-way valves (
A2 and A3). When both valves have no power, CYL 1 is fed. Speed
control: Observe the comments on page 9!
A1 ... common pump
A2 ... valve (A2/S receives power when filling cylinder CYL 2)
A3 ... valve (A3/S receives power when filling cylinder CYL 3)
If there is an active priority allocation in menu PA, then the two valves A2 and A3 are
never switched on simultaneously: when filling into cylinder 2, only pump
A1 and valve A2
are switched on, when filling into cylinder 3, only pump
A1 and valve A3 are switched on.
All programs +4:
If all of the cylinders have reached their maximum temperature, loading to CYL 2 continues
regardless of
max2.
All programs +8: All solar circuits have separate switch-on thresholds at S1:
Output
A1 retains min1, but A2 switches at min2 and A3 at min3.
The priorities for CYL 1, CYL 2 and CYL 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 (see solar
priorities for more details).
