Program 304 – Solar system with 2 collector charging pump (boiler)
Program 304:
Pump
A1
runs, if:
•
S1
exceeds the threshold
min1
• and
S1
is greater than
S3
by the difference
diff1
• and
S3
has not exceeded the threshold
max1
.
Pump
A2
runs, if:
•
S2
exceeds the threshold
min2
• and
S2
is greater than
S3
by the difference
diff1
• and
S3
has not exceeded the threshold
max1
.
The charging pump
A3
runs, if:
•
S4
exceeds the threshold
min3
• and
S4
is greater than
S3
by the difference
diff2
• and
S3
has not exceeded the threshold
max2
.
A1 = S1 > (S3 + diff1) & S1 > min1 & S3 < max1
A2 = S2 > (S3 + diff1) & S2 > min2 & S3 < max1
A3 = S4 > (S3 + diff2) & S4 > min3 & S3 < max2
All pr1:
If the difference between the two solar panel sensors
S1
and
S2
exceeds
the difference
diff3
, the colder panel‘s circuit is deactivated. This prevents heat from being
lost on the colder panel when temperatures are mixed.
All pr2:
Instead of the pumps
A1
and
A2,
one pump
A1
and a three-way valve
A2
are used. Without priority allocation, solar panel 2 will be preferred.
WARNING:
This program is not intended for systems with two solar panels fields, since the
usage of a three-way valve always leaves one solar panel field idle.
Note:
The additional application of the priority circuit „All pr1“ is recommended.
