System
3.1
System characteristics
The solar system is described in the operating instructions.
3.2
Combination with system controller
The product can be combined with the
auroMATIC VRS
620/3
system controller or the controller for the
geoTHERM
heat pumps.
If you combine the product with the
auroMATIC VRS 620/3
system controller, we recommend that you install a
VPM ../2
W
drinking water station.
3.3
Combination with cylinder
The solar charger can be combined with the following cylin-
ders:
–
allSTOR
–
auroSTOR
The cylinder charging circuit must be fitted on-site with a
safety device and expansion vessel. If an
auroSTOR
is in-
stalled, a safety device and expansion vessel are also re-
quired between the
auroSTOR
and solar charger.
Two diverter valves can be installed in the solar system.
1.
The UV4, which is connected to the
auroMATIC VRS
620/3
:
First priority:
allSTOR
Second priority: Swimming pool or other cylinder
2.
The UV5, which is connected to the solar charger:
Switches between heating circuit and hot water circuit
for improved stratified charging
3.4
System conditions
The following conditions must be met by the solar system to
ensure correct operation:
–
The solar charger must be installed below the collector
field
–
The height difference between the bottom edge of
the solar charging system and the top edge of the
collector field must not exceed 6 m (VPM 15 D) or 9 m
(VPM 30 D).
–
The solar lines must be installed with a downward gradi-
ent
–
The maximum number of collectors must not be
exceeded
–
The pipe diameters and lengths of the solar lines must be
observed
More precise information and hydraulic schemes can be
found in the planning information.
