Program 128 – Burner request and solar system (or charging pump)
Program 128:
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
.
Output
A3
is activated, if
S4
falls below the threshold
min3
.
Output
A3
is deactivated (dominantly), if
S3
exceeds the threshold
max3
.
A1 = S1 > (S2 + diff1) & S1 > min1 & S2 < max1
A3 (on) = S4 <min3 A3 (off) = S3 > max3
All pr1:
The burner request (
A3
) is regulated only via
S4.
Output
A3
switches on, if
S4
falls below the threshold
min3
.
Output
A3
switches off (dominantly), if
S4
exceeds the threshold
max3
.
A3 (on) = S4 < min3 A3 (off) = S4 > max3
All pr2:
Additionally, pump
A1
switches between sensors
S4
and
S2,
if the difference
diff2
is
reached (for applications such as a boiler-buffer-cylinder system).
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
,
or
•
S4
has exceeded the threshold
min2
• and
S4
is greater than
S2
by the difference
diff2
• and
S2
has not exceeded the threshold
max1
.
A1 = (S1 > (S2 + diff1) & S1 > min1 & S2 < max1)
or
(S4 > (S2 + diff2) & S4 > min2 & S2 < max1)
