Program 336 – Solar system with 2 consumers and layered cylinder charging
Layered system only practical with speed control activated!
(Absolute value control: mode „Normal“ and sensor input S1)
Program 336:
The solar pumps
A1
run, if:
•
S1
exceeds the threshold
min1
• and
S1
is greater than
S2
by the difference
diff1
• and
S2
has not exceeded the threshold
max1
.
The solar 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 three-way valve
A3
switches
upwards,
if:
•
S5
exceeds the threshold
min3
•
or,
if
S5
falls below the threshold
min3
,
S5
is greater
than
S4
by the difference
• 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 > min3 or S5 > (S4 + diff3)) & S4 < max3
All pr2:
If
S4
has reached the threshold
max3
, the rapid warm-up phase is complet
-
ed and the speed control is blocked, which achieves optimal efficiency.
If control Output A4 is activated, the analogue level for maximum speed will be output. Con
-
trol Output A5 is not affected and continues regulating.
All pr4:
Both solar circuits receive separate activation thresholds
S1:
Output
A1
re
-
tains
min1
and
A2
is regulated via
min2
.
The
Priority Ranking
between
CYL1
and
CYL2
can be parameterized in the menu
Settings/
Technician level/Parameters/Priority ranking
. Additionally, a solar priority function can be
set up in the menu
Settings/Expert level/Solar priority
(further details in chapter „Solar Pri
-
ority“).
