All pr8:
The limiting of tank TK1 is made via the independent sensor
S6
and the
maximum threshold
max1
(no maximum threshold on
S2!
)
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
(see solar priorities
more details).
Program 192 - Solar power system with 2 consumers and feed pump (heating boiler)
Only 1 tank
portrayable
Program 192:
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
.
The feed pump
A3
runs when:
S4
is greater than the threshold
min2
and
S4
is greater than
S3
by the difference
diff3
and
S3
has not exceeded the threshold
max3
.
A1 = S1 > (S2 + diff1) & S1 > min1 & S2 < max1
A2 = S1 > (S3 + diff2) & S1 > min1 & S3 < max2
A3 = S4 > (S3 + diff3) & S4 > min2 & S3 < max3
All pr1:
Instead of both pumps
A1
and
A2
one pump
A1
and a three-way valve
A2
are deployed.
Speed control: Observe the comments on page 9!
Without a priority allocation, tank 2 is filled by priority.
