Program D1:
Threshold
min2
is active at sensor
T6
and switches output
A4
.
Program D2:
instead of the independent temperature difference between
T6
and
T5
the dif-
ference between
T6
and
T4
applies. Hence it is possible to heat one consumer from four
generators.
A4 = T6 > (T4 + diff4) & T4 < max4
Program D4:
Sensor
T3
will be compared with
T5
additionally to sensor
T4
. Hence the boiler
can feed tank
TK1
(
T4
) as well as tank
TK2
(
T5
).
A1 = T1 > (T4 + diff1) & T4 < max1
A2 = T2 > (T4 + diff2) & T2 > min1 & T4 < max2
A3 = T3 > (T4 + diff3) & T3 > min2 & T4 < max3
A4 = T6 > (T5 + diff4) & T5 < max4
or T3 > (T5 + diff4) & T3 > min2 & T5 < max4
