Program 176 – Solar system with 2 consumers and charging pump functionality
Program 176:
Pump
A1
runs, if:
•
S1
exceeds the threshold
min1
• and
S1
is greater than
S2
by the difference
diff1
• and
S2
has not exceeded the threshold
max1
.
Pump
A2
runs, if:
•
S1
exceeds the threshold
min1
• and
S1
is greater than
S3
by the difference
diff2
• and
S3
has not exceeded the threshold
max2
.
The charging pump
A3
runs, if:
•
S5
exceeds 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 pr1:
Instead of the two pumps
A1
and
A2,
one pump
A1
and a three-way valve
A2
are used.
Without priority allocation, cylinder 2 is filled by default.
All pr2:
If both cylinders have reached their maximum temperatures due to the so
-
lar system, pump
A3
is activated (re-cooling function).
All pr4:
Both solar circuits have separate activation thresholds at
S1:
Output
A1
retains
min1
, and
A2
is regulated via
min3
.
