3 System
3.1 System characteristics
3.1.1 Basic principles of the system
The auroFLOW plus solar system acts as a heat generator
in a hot water heating installation with a buffer cylinder. In or-
der to cover the basic load and potential peak loads of the
heat demand, various heat generators are used in solar-sup-
ported heating installations, e.g. heat pumps, block heating
and generating plants and gas boilers. The hot water gener-
ation can be combined with the buffer cylinder.
The auroFLOW plus solar system comprises:
–Collector field
–auroFLOW plus solar charger
–Buffer cylinder
–Solar lines
–Heating water pipes
In addition, a system controller can be used to control all
components of the heating installation, e.g. the auroMATIC
VRS 620.

solar-supported production of hot water in multiple-occu-
pancy houses. Cylinder cascades and swimming pool heat-
ing are possible.
For even larger applications, up to four solar chargers (basic
module and expansion module) can be cascaded. The col-
lector field can then be made up of up to 48 collectors.

System 3
0020160592_00 auroFLOW plus Instructions for use 5
3.1.3 Functionality
The way the auroFLOW plus solar system operates is dif-
ferent to many other solar systems. The auroFLOW plus
solar system is not completely filled with solar fluid and it is
not under pressure. For this reason, some of the otherwise
standard components for solar systems, such as the expan-
sion vessel, pressure gauge and air vent, are not fitted.
When the solar pump is idle, the solar fluid is collected in
the storage tank. The collector field and all solar lines are
installed with downward gradients, to ensure that the solar
fluid flows back to the solar charger. The solar lines and the
collector field are then filled with air. The solar fluid is a spe-
cial ready-mixed water/glycol fluid that is added to the solar
system during installation by the competent person.
When the solar control activates the solar pump, the solar
pump pumps the solar fluid from the storage tank through
the solar return into the collector field. The solar fluid is
heated at this point, before flowing back to the solar charger
via the solar flow pipe.
–When the solar pump is idle, there is air in the collectors
and solar lines. Frost protection measures are therefore
only required for the installation site of the solar charger.
–The collector field and solar lines, and especially the
downward gradient of the lines, must be installed as spe-
cified to ensure that the solar system functions correctly.
–The fluid capacity of the collector field and the solar lines
is precisely designed with the solar system in mind.
–The minimum length and the maximum length of the
solar lines must be observed
–All solar lines have defined diameters in relation to
the number of collectors
–The use of corrugated hoses impairs the functionality
of the solar system
–The design and number of collectors must not be
changed
–The physical properties of the solar fluid are also an im-
portant contributing factor to the fault-free operation of
the system. Therefore, only original Vaillant solar fluid
without additives may be added to the system.

The way the basic module of the solar charger operates is
described below.
If the expansion module is also installed,
–the solar fluid volume is doubled by a separate storage
tank connected in parallel
–the pump output is higher as a result of two solar pumps
connected in series
The way the solar charger operates remains the same, how-
ever.
When the solar pump is idle, only the storage tank (8) con-
tains solar fluid. The collectors (1) and solar lines (2) and (9)
are then filled with air.
The solar control in the solar charger activates the solar
pump whenever
–the temperature difference between the collector temper-
ature sensor (T5) and cylinder temperature sensor (T6) is
at least 15 K (if a system controller is connected, the cyl-
inder temperature is transmitted to the solar control via
the eBUS line)
–the cylinder temperature is lower than the set maximum
cylinder temperature

3 System
6Instructions for use auroFLOW plus 0020160592_00
–the anti-cycling time of ten minutes after the last cylinder
charging has expired
–the safety temperature limit of 110 °C in the solar circuit
is not exceeded (STW2)
–the safety temperature limit in the buffer cylinder (4) is
not exceeded (STW1)
–the temperature has fallen by at least 15 K following ac-
tivation of a safety cut-out
–there are no faults (e.g. sensor faults, activated safety
temperature monitor)
–activation of the solar pump is enabled (only if a system
controller is connected)
The solar control in the solar charger deactivates the solar
pump whenever
–the maximum cylinder temperature is reached
–current solar radiation is < 250 W
–there is a fault, see fault message (→Page 9)
Every time the solar pump is switched on, a filling phase is
started. The solar pump ((P1) and/or (P2)) is now working
at maximum power and pumps the solar fluid via the solar
return (2) into the collector field. The solar fluid then forces
the air out of the solar return and the collector field into the
solar flow pipe and the storage tank.
In the collector field, the solar fluid is heated up, some of
which can then evaporate. The vapour mixes with the air that
is still present.
The continued flow of the solar fluid is supported by the
downward gradient of the solar flow pipe (9). The air and
solar fluid mixture passes through the solar flow pipe to the
heat exchanger (3) in the solar charger. The heat exchanger
transfers the heat energy of the solar fluid to the heating
water in the buffer cylinder charging circuit. After a specified
filling time, the solar control reduces the output of the solar
pump. The filling phase is then completed.
If (T1) measures a temperature > 50 °C and > activation
temperature (default setting: 15 K), the solar control activ-
ates the cylinder charging pump (P3) in the solar charger.
The heating water then circulates from the heat exchanger to
the buffer cylinder.
The temperature sensors (T3) and (T4) in the flow (5) and
return (6) of the buffer cylinder charging circuit as well as a
flow sensor (Flowsensor) enable the solar control to meas-
ure the solar yield.
The solar fluid flows back from the heat exchanger into the
storage tank. The tank volume dimensions are such that the
air bubbles from the solar fluid are separated out before the
solar fluid is pumped further by the solar pump.
When the solar system heats up, the solar fluid and the air
expand. The pressure of the air enclosed in the solar sys-
tem increases slightly as a result. The enclosed air in the
system therefore fulfils the role of an expansion vessel. The
increased pressure is necessary and must not be discharged
in any way. For this reason, an air vent must not be fitted in
the solar system.
If there is a fault, an expansion relief valve (7) protects the
solar plant from prohibited overpressure.
3.2 Control functions of the system
With the help of the solar control integrated in the solar char-
ger, the solar charger can charge a buffer cylinder. Whether
or not the buffer cylinder is charged depends on the cylinder
temperature and the current solar radiation.
If coordination with other heat generators of the heating in-
stallation is required, a system controller is needed.
3.2.1 Range of available functions for the
integrated controller
The auroFLOW plus solar system is regulated by the integ-
rated, microprocessor-controlled solar control.
3.2.1.1 Differential temperature control system
The solar control works according to the differential tem-
perature control principle. When the temperature difference
(temperature of collector - temperature of cylinder) is greater
than the switch-on differential, the solar control switches on
the solar pump. The internal sensors in the solar charger de-
termine the power through the collector field. When power is
no longer available from the collector field, the solar control
switches off the solar pump.
3.2.1.2 Annual calendar
The solar control is fitted with an annual calendar that en-
ables automatic adjustment between summer and winter
time. During installation, the competent person enters the
current date to activate the annual calendar.
Note
Note that, in the event of a power failure, the solar
control is equipped with a reserve power supply
of 30 minutes. The internal clock stops after 30
minutes. The calendar does not continue run-
ning once the voltage supply is restored. In this
instance, the time must be reset. Check the cur-
rent date.
Note
If a system controller is connected, it is not neces-
sary to set the date, time or summer time.
3.2.2 Combination with system controller
The product can be combined with the auroMATIC VRS 620
system controller or the controller of the geoTHERM heat
pumps.
If the product is combined with the auroMATIC VRS 620
system controller, we recommend the installation of a VPM
Wdrinking water station.

occurs in the solar system, the solar system switches itself
off. The display of the solar charger displays a fault code in
place of the basic display. A plain text display explains the
displayed fault code.
If multiple faults occur at the same time, the display shows
the corresponding fault codes for two seconds each in se-
quence.
▶If the solar charger displays a fault message, contact
your approved competent person.
Note
Status messages about the condition of the
solar system can be called up using the Live
Monitor (→Page 12) function.
5.1.1 Fault message

7 Maintenance
7.1 Servicing the solar system
Danger!
Risk of injury and material damage due to
incorrect maintenance and repairs.
Failure to carry out maintenance, or in-
correctly completed maintenance, may
adversely affect the operational reliability of
the solar system.
▶Never attempt to carry out maintenance
work or repairs on the solar system your-
self.
▶Always employ a competent person.
Permanent operational readiness and safety, reliability and
a long working life require inspections and maintenance
work to be carried out annually on the solar system by an
approved competent person.
Regular maintenance ensures maximum efficiency and eco-
