Program 352 – Layered cylinder and burner request
Layered system only practical with speed control activated!
(Absolute value control: mode „Normal“ and sensor input S1)
Program 352:
Pumps
A1
run, 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 three-way valve
A2
switches
upwards,
if:
•
S5
exceeds the threshold
min2
•
or,
if
S5
falls below
min2
,
S5
is greater than
S4
by the
difference
diff2
.
• and
S4
has not exceeded the threshold
max2
.
Output
A3
is activated, if
S4
falls below
min3
.
Output
A3
is deactivated (dominantly), if
S3
exceeds the threshold
max3
.
A1 = S1 > (S2 + diff1) & S1 > min1 & S2 < max1
A2 = (S5 > min2 or S5 > (S4 + diff2)) & S4 < max2
A3 (on) = S4 < min3 A3 (off) = S3 > max3
All pr1: All pr1:
If
S4
has reached the threshold
max2
, the rapid warm-up
phase is completed and the speed control is blocked, which achieves optimal efficiency.
If control Output A4 is activated, the analogue level for maximum speed will be output. Con
-
trol Output A5 is not affected and continues regulating.
All pr4:
The burner request (
A3
) is only regulated via
S4.
A3 (on) = S4 < min3 A3 (off) = S4 > max3
(dominant)
All pr8:
If the solar circuit is active, the burner request is blocked. If the solar circuit
is inactive, the burner request is unblocked after a 5 minute delay..
