Program 576 – Cascade: S4 -> S1 -> S2 + burner request
Program 576:
The charging 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
.
The charging pump
A2
runs, if:
•
S4
exceeds the threshold
min2
• and
S4
is greater than
S1
by the difference
diff2
• and
S1
has not exceeded the threshold
max2
.
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
A2 = S4 > (S1 + diff2) & S4 > min2 & S1 < max2
A3 (on) = S4 < min3 A3 (off) = S3 > max3
All pr1:
The burner request (
A3
) is regulated only via
S4
(deactivation dominant).
A3 (on) = S4 < min3 A3 (off) = S4 > max3
