Pump
A1
runs, if:
•
S4
exceeds the threshold
min1
• and
S4
is greater than
S1
by the difference
diff1
• and
S1
has not exceeded the threshold
max1
.
or
•
S5
exceeds the threshold
min2
• and
S5
is greater than
S1
by the difference
diff3
• and
S1
has not exceeded the threshold
max1
.
Pump
A2
runs, if:
•
S4
exceeds the threshold
min1
• and
S4
is greater than
S2
by the difference
diff2
• and
S2
has not exceeded the threshold
max2
.
or
•
S5
exceeds the threshold
min2
• and
S5
is greater than
S2
by the difference
diff3
• and
S2
has not exceeded the threshold
max2
.
All pr4:
The burner request (
A3
) is only regulated via
S4.
A3 (on) = S4 < min3 A3 (off) = S4 > max3
(dominantly)
All pr8:
(Not usable in conjunction with +2)
Both charging pump circuits have separate activation thresholds at
S4
:
Output
A1
retains
min1
and
A2
is regulated via
min2
.
The
Priority Ranking
between
CYL1
and
CYL2
can be set in the menu
Settings/Technician
level/Parameters/Priority ranking
.
