1. Pump station with integrated controller
•With Grundfos Direct SensorsTM
•High efficiency pump (product version F l o w C o n
S e n s o r HE) funded by a number of national incentive
programs
•Precise measurement of temperature, pressure and
flow rate
•Advanced error diagnostic system
•Heat quantity measurement
•Full graphic display
•RESOL VBus®
The F lo w C o n S e n s o r / S e n s o r H E is a complete
pump station that is delivered with all the electric and
hydraulic core components of the solar system, including
the sensors required, pre-assembled in one easy-to-mount
unit. The separate installation of collector and store sen-
sors is not required.
The F l o w C o n S e n s o r / S e n s o r H E offers the effi-
ciency and the functional range of a standard solar system
while being much more reliable and requiring less instal-
lation effort.
The station is equipped with important components and
safety assemblies for operating the solar thermal system:
•Ball valves in flow and return in combination with check
valves to prevent gravity circulation
•Digital sensors for measuring temperature, pressure
and flow rate
•AirStopp for manual bleeding of the solar thermal system
•Manometer for displaying the system pressure
•Safety valve to prevent inadmissible overpressure
•High-efficiency pump (F l o w C o n S e n s o r H E only)
In order to optimise the time frame, the algorithm takes a
range of parameters into account, e. g. the tilt and the ori-
entation of the collector, the geographical position as well as
the season. Furthermore, the testing time frame is adjusted
to the typical identified store temperature.
Sequence of control phases of the F lo w C o n S e n s o r :
Loading
yes
no
no
30 min pause
Identification The testing time frame begins with an identification
phase. The controller activates the pump at minimum
speed to check whether a solar gain might be possible.
If a solar gain is possible, the stabilising phase is started,
during which the pump remains active and the controller
continues to test for the possibility of an efficient solar gain.
The pump station commences normal operation, i. e. it
enters the loading phase. The store is loaded as long as
an efficient solar gain is possible.
yes
Stabilising
What makes the F l o w C o n S e n s o r so special is its con-
trol algorithm. For each individual operating day, it calculates
a specific time frame during which it is sensible to start the
pump for testing purposes. The integrated sensors then
identify the collector and store temperatures by experi-
mentally activating the pump.
If no solar loading is possible, a 30 min pause is run in
order to give the collector time to heat up.

The installation and commissioning of the solar station as
well as the connection of electrical components requires
technical knowledge commensurate with a recognised
vocational qualification as a fitter for plumbing, heating and
air conditioning technology, or a profession requiring a com-
parable level of knowledge. The following must be observed
during installation and commissioning:
• the relevant regional and national regulations
• the accident prevention regulations of the trade association
• the technical and safety instructions of these instructions
Safety instructions
WARNING: Risk of scalding
There is a danger of steam emission with safety val-
ves. Therefore a discharge pipe must be connected
to the ¾“ internal thread of the safety assembly.
Please observe the enclosed instructions regarding
the safety valve when doing this.
Attention: Damage to property
The group of fittings must be installed with suffi-
cient spacing to the collectors because tempera-
tures in the vicinity of the collectors can be very
high. An intermediate vessel may be necessary for
installation in the attic.
Attention: Damage to property
It is imperative that you make sure the EPDM
sealing elements of the solar station do not come
into contact with substances containing mineral oil.
Mineral oil products cause lasting damage to the
material, whereby its sealant properties are lost.
If necessary, ask the manufacturer whether the
solar fluid, fats or installation aids contain mineral
oils.
The manufacturer does not assume liability nor
provide warranty for damage to property resulting
from sealants damaged in this way.

WARNING! Scald danger!
Danger of severe application damage!
Flushing and/or filling the system on a
very sunny day can lead to a sudden
volatilisation of heat transfer fluid.
ÎDo not flush or fill the system
during p e r io d s of strong
sunshine!
ATTENTION! Frost damage!
It is impossible to completely empty a
solar system once it has been flushed.
If water is used for flushing the system,
frost damage can occur. Use heat trans-
fer fluid to flush and fill the system.
ÎUse a mixture of water and propyle-
ne or ethylene (max. 50 % propylene/
ethylene) as a heat transfer fluid!
Note
If the pump is to support the flushing and filling
process, the controller has to be commissioned
first! For detailed information see chap. 11.2.

ÎOpen the fill valve (3) and the drain valve (5)
ÎTurn the ball valves in flow (1) and in return (2) with
an open-ended spanner (wrench width 14) to a 45°
position. The non-return valves in the ball valves are
now open (fig. 4)
ÎFlush the solar thermal system by means of the flushing
and filling station until the discharged solar fluid is free
of dirt particles.
During this process, the solar pump may run in “Max.” ma-
nual mode. (Observe note in chap. 3!)
ÎSwitch off the filling pump
If the steps described in chapter 3.1,1 have not been carried
out yet, please do so before proceeding with the following
steps
ÎFlush the solar thermal system using the flushing and
filling station for at least 15 minutes to remove all air
from the system.
During this process, the solar pump may run in “Max.” ma-
nual mode. (Observe note in chap. 3!)
ÎDuring flushing, bleed the solar thermal system several
times at the AirStopp until the discharged solar fluid is
free of air bubbles
ÎConnect the expansion vessel to the solar thermal
system
ÎClose the drain valve (5) of the flushing and filling unit
with the filling pump running and increase the system
pressure to approx. 5 bar
The system pressure can be read from the manometer
ÎClose the fill valve (3) and switch off the pump of the
flushing and filling station as well as the solar pump
ÎCheck the manometer to see whether the system
pressure reduces (approx. 15 minutes) and eliminate
leaks where necessary
ÎSet the operating pressure of the solar thermal system
(approx. 0.5 bar higher than the inlet pressure of the
expansion vessel) by opening the drain valve (5)
ÎClose the drain valve (5) and open the ball valve (4)
ÎRemove the hoses of the flushing and filling station and
screw the caps onto the fill and drain valves

solar thermal system, where available
ÎDispose of the heat transfer fluid in observance of local
regulations
3.2 Emptying the solar thermal system
The AirStopp (manual bleed valve) is a device for bleeding
the solar fluid in the solar thermal system. The air preci-
pitated from the solar fluid gathers in the upper area of
the manual bleed valve (see diagram) and can, if required,
be discharged at the bleeding valve. To guarantee faultless
bleeding of the collector circuit the flow rate in the flow
must be at least 0.3 m/s.
ÎCheck the system pressure after bleeding and, if neces-
sary, increase it to the specified operating pressure
4. AirStopp
Bleeding the solar thermal system directly after
commissioning
After commissioning, bleed the solar thermal system daily,
then decrease the bleeding interval to a weekly or monthly
frequency, depending on the volume of discharged air.
WARNING! Scald danger!
The discharging liquid may be very hot.
ÎLocate the collecting vessel so
that people standing nearby
are not endangered while the
system is emptied.
WARNING! Scald danger!
Discharging fluid or gas may be very hot.
ÎKeep all body parts away from
the opening of the bleeding valve
during bleeding!
Information for the operator of the system
Bleed the solar thermal system every six months
with the manual bleed valve to achieve optimal
efficiency!
ATTENTION! Pressure surge damage!
Activating the pump regardless of a
collector stagnation may cause system
damage!
ΓAssign static pressure ! ”
must only be selected if no
stagnation is possible!
ÎPress button 3 for approx. two seconds
ÎSelect “Status”
ÎScroll to “Assign static pressure!” by pressing buttons
1 and 2
ÎSelect “Assign static pressure!”
The controller will now store the current system pressure
as the new static pressure.
For more information about stagnation see chap. 14.

ÎBriefly press button 3 to confirm the selection
ÎTo store the adjustment and get back to the commissi-
oning assistant , press button 3 again
If “Adjust” is selected, the adjustment channels for the vo-
lumes of the different system parts appear as shown below.
Pipe material: Select from “Copper” or “Steel”
Diam. Col->St: Diameter of the pipes between collector
and pump station
Diam. HX- >St: Diameter of the pipes between heat
exchanger and pump station
Length Col->St: Length of the pipes between collector
and pump station
Length HX->St: Length of the pipes between heat ex-
changer and pump station
Volume CF: Volume of the collector field
Volume HX: Volume of the heat exchanger
As soon as “Volume HX” has been entered and confirmed,
the commissioning assistant can be completed and exited
(see below).
If “Automatic” is selected, the controller adapts the ne-
cessary volumes automatically. The adaptation process runs
until in at least five identification phases, the maximum flow
temperature has exceeded the initial flow temperature by at
least 20 K. This means that for a successful adaptation, the
standstill temperature of the collector must be significantly
higher than the temperature of the pump station.
During winter or long-term periods of weak irradiation,
the adaptation process may take up to several weeks to
complete. While the adaptation is in progress, the system is
operable and can be used at a near-normal level of efficiency.
The main difference to the regular control cycle lies in the
identification phases: they start at a later time of the day and
have a longer runtime than during normal operation.
As long as the adaptation process is in progress, the mes-
sage “Adaptation in progress” is displayed in the status
menu (see chap. 15.1). As soon as the adaptation process
has been successfully completed, the controller automati-
cally switches to its regular control cycle.
If “Automatic” has been selected, the commissioning assi-
stant can be completed and exited (see below).

During normal operation, the parameters adjusted by me-
ans of the commissioning assistant can be accessed in the
expert area of the adjustment values menu (see chap. 15).
If they are to be changed, this can be done in the following
submenus:
•Volume adaptation (pipe parameters etc.)
•Country parameters (country, time zone etc.)
•System parameters (tilt angle, orientation etc.)
11.3 Adjusting the minimum pump speed
Note:
The adjustment values in the expert area should
only be altered by qualified personnel. Other-
wise, the system may not function faultlessly!
After the commissioning assistant has been successfully
completed, the minimum speed of the pump must be adju-
sted. To do so, proceed as follows:
ÎKeep button 3 pressed for approx. two seconds
The main menu appears.
ÎSelect “Adjustment values”
ÎScroll down to “Relay mode” by pressing button 2
ÎSelect “Relay mode” by pressing button 3
ÎSelect “Min.” and confirm by pressing button 3 again
In the menu line below “Relay mode”, the adjustment
channel “Min. speed” appears, in the line below that, the
current flow rate is shown.
ÎSelect “Min. speed”
ÎAdjust the minimum pump speed so that the flow rate
reaches the desired value
ÎConfirm by pressing button 3

Adjustment values
Note:
Observe the specifications of the pump and
the collector manufacturer when adjusting the
minimum pump speed!
If the flow rate remains below 100 l/h at the
adjusted minimum pump speed, the control-
ler will increase the pump speed until the flow
rate surpasses 100 l/h.
After the adjustment of the minimum pump speed,
the relay mode should be set back to “Auto”.
Otherwise, the efficiency and reliability of the system will
not be optimal.
To do so, proceed as follows:
ÎSelect the menu item “Relay mode” as described above
ÎSelect “Auto”
ÎConfirm by pressing button 3
For more information about the different relay modes see
chap. 15.3.
Note:
The system takes about 30 seconds to adjust to
a new minimum speed. Always wait for 30 se-
conds before readjusting the minimum speed!

In the system display, the fl ow and return temperatures as
well as the pump speed are displayed.
Above the store symbol, the current operational status is
displayed (“Standby”, “Pause”, “Identifi cation”, “Stabilising”,
“Loading”, “Readiness”, “Store cooling”, “Overrun”, “Stagna-
tion”, “Inhibition”).
If the operational status is “Standby”, “Pause”, “Identifi ca-
tion”, “Stabilising” or “Overrun”, the remaining runtime of
the corresponding phase is displayed as a countdown.
See below for more information about the different status:
System display
During normal operation, the controller display shows the
info area. The info area consists of a range of displays that
allow a close monitoring of the sensor and system data.
ÎTo switch between the different displays of the info
area, press buttons 1 and 2
The status is displayed graphically by means of a smiley. The
different smiley faces have the following meanings:
System ok everything is alright
Warning an error has occured, system operation
is not aborted (except for “Leakage”
and “Overpressure”, see chap. 16.2)
Error an error has occured, system operation
has been aborted
For more information about the possible error and warning
messages see chapter 16 “Messages”.
Operational status Outside the testing time frame, the controller is in standby
phase. In the system display and the status menu, the remai-
ning time until the next testing time frame is displayed as a
countdown (hh:mm).
Standby
A pause is run whenever
•an identifi cation phase has been unsuccessful
•a stabilising phase has been unsuccessful
•the DT does not rise to > 5 K during an overrun phase
•Tstmax is exceeded (resp. Tstsec if “Readiness” is active)
•an error-induced inhibition has ended
In the system display and the status menu, the remaining
time of the phase is displayed as a countdown (mm:ss).
Pause
After every pause, an identifi cation phase is run. The pump
is activated at minimum speed in order to identify the coll-
ector temperature. If a suffi ciently high difference between
the collector and the store temperature, the so-called DT,
(minimum 5 K) is measured, a stabilising phase follows. If the
DT measured is not suffi ciently high, a pause is run.
In the system display and the status menu, the remaining
time of the phase is displayed as a countdown (mm:ss).
The duration of the identifi cation phase adjusts itself to the
current fl ow rate. This may lead to sudden changes in the
countdown displayed if the fl ow rate fl uctuates.
Identifi cation
Note:
System pressure is measured at the pump inlet.
Therefore, the values measured at the digital
sensor may differ from those shown on the ma-
nometer when the pump is active.
Note:
In most cases, the pause has a duration of 30
minutes. During summer, the controller may
shorten the pause in order to avoid a collector
stagnation caused by stillstand periods.
