Program 432:
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
.
The feed pump
A2
runs when:
S3
is greater than the threshold
min2
and
S3
is greater than
S4
by the difference
diff2
and
S4
has not exceeded the threshold
max2
.
Output
A3
switches on when
S5
falls below threshold
min3
.
Output
A3
switches off (dominant) when
S4
exceeds
max3
.
A1 = S1 > (S2 + diff1) & S1 > min1 & S2 < max1
A2 = S3 > (S4 + diff2) & S3 > min2 & S4 < max2
A3
(on)
=
S5
<
min3
A3 (off) = S4 > max3
Program 433:

A1 = S1 > (S2 + diff1) & S1 > min1 & S2 < max1
A2 = S3 > (S2 + diff2) & S3 > min2 & S2 < max2
A3
(on)
=
S5
<
min3
A3 (off) = S4 > max3
All pr2:
The burner requirement (
A3
) only occurs via sensor
S5
.
A3 (on) = S5 < min3
A3 (off) = S5 > max3
(dominant)
All p4:
if sensor
S2
has reached the threshold
max1
pump
A2
is activated and
pump
A1
continues running. A "cooling function" to the boiler or the heating is thereby
achieved without the occurrence of standstill temperatures at the collector.
All pr8:
An active solar circuit blocks the burner requirement. After switching off the
solar circuit the release of the requirement occurs with a delay of 5 minutes.
