2 Information about the System
Congratulations on your purchase of the SolvisDirekt
system. The main feature of this system is the central,
hygienic and economic water heating.
General functional description (Figure on right)
The hot water station WWS-36 as part of the SolvisDirekt
system consists of components (1) and (2). The cold water
(CW) is heated via a plate heat exchanger (1) through the
heating circuit with the help of a buffer discharging station
(2) in direct flow to a constant usage temperature. The
heat is held in the SolvisStrato stratified buffer tank (3).
Instead of a large hot water volume which has greater
hygiene risks and requires considerable energy to maintain
the temperature, the demand is covered by an efficient
fresh water system. The boiler (4) charges the stratified
buffer tank. You can connect a room heating system (5).
You can easily expand the system into a thermal solar
system, consisting of a solar heat transfer station (6) and
a collector field (7).

Advantages of the SolvisDirekt system
With the SolvisStrato stratified buffer tank integrated in the
fresh water system (figure on right), you benefit from our
patented stratified charger technology: Compared to standard buffer tanks, you can use the heat more efficiently
(SERC comparative test, see SolvisStrato planning document P10) and heat water more conveniently (ITW comparative test).
The system solution is particularly unique thanks to:
• High savings potential for energy costs,
• Hygienic and fresh hot water provided at the target tem-
perature, even with low water levels or after extended
periods of standstill,
• Forward-looking upgrading, for example, with a thermal
solar system to optimise the return,
• A high degree of installation reliability due to the prefabri-
cation of the functional modules,
• Reliable adaptation to requirements through modules
with guaranteed high performance,
• Simple operational monitoring by saving results and
• integration of variable heat sources that can be
combined.

Information about the system
2.1 SolvisStrato stratified buffer tank
The SolvisStrato stratified buffer tank was designed especially for use in solar systems. It is the core element of
your heating system. In the Low-Flow System from Solvis,
your SolvisStrato can be used with all collector surfaces
up to 40 m².
In closed systems, an insulating jacket encases the steel
container. All connections are routed downward underneath
the insulation. The pipelines connect your SolvisStrato with
the hot water station (section 2.2), the boiler (see oper-
ating instructions of the manufacturer), the heating circuits and the solar heat transfer station (section 2.3).
The stratified charging system
One of the essential features of the stratified buffer tank is
the separation of the water into three zones:
• Hot water buffer layer
In the uppermost layer, there is hot water for heating of
drinking water. Depending on the tank size, 90 to 200 l
are stored here, so that enough water is heated for small
and average dispensable amounts even at times when
there is no auxiliary heating, e.g. at night.
• Heating buffer layer
The middle layer contains hot water for the heating.
• Solar buffer layer
The lower layer contains colder water to be heated by the
solar power system.
SolvisStrato Stratified Buffer Tank
The heat from the collector is delivered into the secondary
solar circuit using the solar heat transfer station. The solar
flow discharges into a pipe with membrane flaps in the
storage tank – the stratified charger. These two elements
work in the following way (figure on right):
The external solar heat exchanger transmits the heat generated by solar power to the water in the tank. The water in
the tank rises. Then the stratified charger ensures that it is
layered according to temperature: hot water at the top, hot
water below.
Please contact your installation firm if you have any
questions regarding the function and control of your
system.

Information about the system
2.2 Hot water station WWS-xx
The hot water station WWS-xx is as described in section 2
the core element of the SolvisDirekt system. It includes
all components required for heating drinking water to the
desired temperature.
The hot water station consists of a plate heat exchanger
(PHE) as well as a buffer charging station and it has an
integrated volume flow encoder to control the heating of
drinking water based on demand. It also includes thermometers to measure the flow and return temperature of
the primary circuit of the plate heat exchanger.
All components are mounted on a console that you can
either stand upright or mount on the wall using the appropriate mounting hardware. Use flushing valves at each connection to maintain the PHE.
Depending on the demand for hot water, you can choose
from two different hot water stations:
Client
• WWS-24, up to 24 l/min hot water flow rate
• WWS-36, up to 36 l/min hot water flow rate
with a temperature increase of 35 Kelvin.

Information about the system
2.3 Solar heat transfer station SÜS-xx
This optional component of your supply unit makes sure
that the heat from the sun can be used. A solar heat
exchanger functions as the central component to which the
solar collector and stratified buffer tank are connected (by
means of two hydraulically separate circuits). The SolvisControl system controller regulates the solar circuit and
buffer circuit pumps. It also controls the speed of each
pump.
Depending on the size of the connected collector area,
there are three different sizes:
• SÜS-20, up to 20 m² opening surface
• SÜS-40, 20 to 40 m² opening surface
• SÜS-80, 40 to 80 m² opening surface.
2.4 SolvisControl system controller
The system controller coordinates all components.
SolvisControl functions:
• Hygienic water heating with time-controlled auxiliary
heating of the buffer
• Time-controlled swimming pool heating in addition to
pure solar heating
• Solar circuit control with two speed-controlled pumps,
including a frost protection function in the secondary
circuit
• Control of two mixed heating circuits
• Heating circuit 1 with floor drying function
• Heat quantity counter for solar circuit
• Circulation
Special features:
• Calendar function with automatic daylight saving time
setting
• Output for reading the data using a data logger

3 Switching on the System
Start-up: Your heating contractor has installed and started
up your system. S/he should also have explained to you
how to operate the system.
Resuming operation: If you want to start up the heating
system after an extended period of standstill, observe the
following instructions:
1. Check that the system is filled and bled of air in accordance with regulations.
2. Ensure that the gas and oil valve on the supply line to
the boiler is open.
3. Switch on the boiler. Consult the operating instructions
for the boiler to ascertain the start-up procedure.
4. Switch on the system controller using the main switch
next to the control board (figure on right). The function
overview menu is called up approx. 30 seconds after
the version display. If the switch does not light up, the
power supply has probably been interrupted by the
emergency stop switch, which is usually next to the
boiler or (outside) on the heating room door.
Client
Main switch
Switch on the system
5. Please always check whether the time and date have
been set correctly. Set the time and date if necessary
(page 12).
If the boiler does not start immediately, check that there is
a heating requirement at the controller. There are two main
reasons for a missing heating requirement:
1. The storage tank is at the set temperature.
2. There is no heating or hot water requirement.
In both cases, the boiler remains switched off.
A heating requirement is indicated by Output 12 being
highlighted in black (see figure on right). In this case, the
boiler should start up automatically after a while. The hot
water or heating buffer in the storage tank (page 6) is then
heated and supplies the heat consumers. If the temperature in the heating buffer exceeds the target value, the
burner is switched off.

Output 12 is highlighted in black
(burner is on). This means the controller
is signalling a heating requirement.

(S13) , as circulation sensor (S11) or as hot water
return sensor lets you control the hot water circulation
with SolvisControl. With 3 m connection cable, including
heat-conducting paste, cable ties and insulation bush.
If S11 is connected, you may have to set the times for

• Volume flow encoder VSG-2,5 (figure on right)
for connection to SolvisControl, input S15. This allows
you to measure and display the current heat output
and the accepted heat quantity in the secondary solar
circuit.
Suitable for up to 1.5 m³/h. Including screw connections
for 18 and 10 CU pipe (solar line).
The impulse rate of the volume flow encoder is
0.5 l/Imp. and is installed on the relevant input (S15)
of the SolvisControl at the factory.
If you are using an on-site volume flow encoder, you will
have to set the impulse rate at input S15. . . .page 30

Limitation:
- You can connect only one room sensor.
- You may only operate this sensor at heat circuit 1.
- You are no longer able to heat a swimming pool.
You can also use the room sensor to control the
room temperature in the respective room based
on the flow temperature so that it takes into consideration external heat sources such as a fireplace or sun exposure. All radiator valves in that
room have to be open for that purpose. You will
also have to set the so-called “room influence
factor” on the SolvisControl. More information in
section “4.4 Using the room sensor”. .page 16

P32-EN – Subject to technical changes 04.11
Operating the System Controller
4.4 Using the room sensor (accessory)
You use the room sensor to conveniently set the room
temperature and heating program (figure on right) without
having to go to the heating system.
If it is too cold, for example, even when the radiator valves
are open, you can increase the room temperature by
turning the adjustment wheel clockwise. If it is too warm,
you turn the adjustment wheel anti-clockwise.
Taking the room temperature into consideration:
The room influence factor was set to zero at the factory so
that the flow temperature is independent of the room temperature and is only set by the heat curve depending on
the outside temperature. Any heat emission from external
heat sources (e.g. fireplace or sun exposure) is to be
offset by thermostat valves so that the room temperature
remains constant. However, the flow temperature remains
too high when compared to the outside temperature
resulting in more losses. You would save more energy if
you lowered the flow temperature to keep the room temperature constant when there is an additional heat supply.
This can be accomplished with the room sensor. By setting
the room influence factor to values greater than 0%, you
can control the influence of the measured room temperature on the value of the flow temperature. This works only
if the valves on the radiators in the room are fully open.
• Changing the room temperature
by plus/minus 5°C
• Selection of the following heating programs:
- Standby mode . . . . . . . . . . . . .
- Night (lowering) mode . . . . . . . .
- Normal mode . . . . . . . . . . . . . .
- Automatic mode . . . . . . . . . . . .
You need to adjust the controller after installation
of the room sensor. . . . . . . . . . . . . . . . .page 27
.
Client
If you set the room influence factor to the maximum value
of 90%, the flow temperature will basically be calculated
based on the measured room temperature. The flow temperature is then influenced by external heat sources so
that rooms without room sensors may not be heated adequately any longer, for example, because they are located
on the cooler north side of the house.
Setting the room influence factor
The room influence factor was set to 0% at the factory. To
save energy by altering the flow temperature, you will have
to change the room influence factor when there are room
sensors installed to 50% at the controller as follows:
Turn the adjustment wheel until you see the entry “HEAT
CURVE” of heating circuit 1 and press the adjustment
wheel.
Now turn the adjustment wheel to the entry “Room
influenc: 0%”. Press the adjustment wheel and set the
desired value by turning the adjustment wheel. Press the
adjustment wheel once at the end to save the value.

4.5 Overview of time programs
Use the following tables to plan the heating of rooms to a
target temperature, the times for auxiliary heating of the
hot water buffer, the operation of the circulation pump and
the heating of swimming pool water, then transfer the information to your controller.
For the heating circuits, you can define 3 time blocks with
3 heating times, where an individual target temperature
can be set for each time period (page 35). The auxiliary
heating times for hot water heating (page 43) and standby
times for circulation (page 46) can be defined using 3 time
blocks with 3 time windows each. You can set two time
windows for swimming pool heating (page 45).
You must first decide on which weekdays the common
time windows are to be valid and then enter them. To do
this, select the appropriate days of the week and set the
time window.

If the boiler does not start up, check that there is a
heating requirement (see page 9). If there is no heating
requirement but you believe that there should be one,
make sure that the time is set correctly (page 12). Next,
check the time programs: the heating circuit, water heating
or the circulation may be outside of the time windows
(page 16f). If the circulation is not working, make sure
that the operating mode is set to “Time” (page 46).
Finally, have a look at the top line on the display and
make sure that there is a hand symbol under one of
the numbers (figure on right). If there is a hand symbol,
the relevant output is set to manual mode and must
be switched to automatic mode (page 28).
If the SolvisControl display no longer responds when
you turn the rotary wheel, switch the control off,
wait 20 seconds, and then switch it back on again.

Each time after a setting has been changed on the system controller, you should wait a while (one or more days) before
making any further changes. As a result of physical conditions, changes to the parameters in the control system can
often cause fluctuations of the control area (room temperature), which, depending on the existing conditions, can reach
a constant value relatively quickly.
**
First of all, open all the heating valves fully. If all rooms are too warm or too cold, change the heating curve accordingly
on the system controller. If one or more rooms have the correct temperature and the other rooms are too warm, the
heating valves must be closed some more in these rooms. There must always be at least one room in which the
heating valves are fully opened (reference room). This is usually the room that is most difficult to heat.

* First of all, open all the heating valves fully. Only when one or more rooms have an adequate temperature and the other
rooms are too warm do you have to close the heating valves in those rooms some more. If it is too cold in a room, first
turn up the heating valves there before you change the heating curve.

“WARNING dT-Solar”
An additional continuous function check of these sensors
takes place together with the monitoring of sensors S3
(tank reference sensor “T.Ref.Sto”) and S8 (collector temperature sensor “T.Collector”) as required for the granting
of incentives according to the market incentive program of
the German federal government (www.BAFA.de):
The “WARNING dT-Solar” message (figure on right)
appears when the collector sensor is 60 K warmer than
the tank reference sensor for more than 30 minutes while
the solar pump is running. The sensor is reset automatically when the temperature difference drops below 60 K.
This message means that very little heat is being collected
by the solar heat exchanger.

“MESSAGE Excess Temp.”
The “WW buffer temp. (S1)” sensor at the top of the tank
is monitored for safety reasons. If the temperature is
greater than 98°C at this point, the solar pump and burner
are switched off. They can no longer be manually switched
on, even in the outputs menu. The following message
appears in the function overview: “MESSAGE Excess
Temp. since: dd.mm. at hh:mm” (figure on right) and
“PROTEC/OFF” is displayed instead of “AUTO” or “HAND”
in the outputs menu for outputs 1 (solar pump) and 12
(burner). This safety function has a hysteresis of 8 K that
can be set, i.e. the burner and solar pump can resume
operation when the temperature is once again below 90°C
(98°C minus 8 K).
For safety reasons, this safety function should
always be activated and its parameters should not
be changed.
“MESSAGE Puffer voll”
If the maximum temperatures at the top of the storage
tank (S1, “T.Lim.MAX“, factory setting 95°C) or at the
bottom (S3, “T.Ref.MAX“, 90°C) are reached, the solar
pump is turned off and the “MESSAGE Puffer voll”
(“buffer full”) appears. Further explanation on page 55.

temperature on the heating circuit flow against controller
values). Call the “Inputs” submenu in the main menu.
Sensor value “9999” means that no sensor is connected
or there is sensor/cable breakage. “-999” indicates a
short circuit.
• Perform a function check of the outputs (pumps). When
the volume flow sensor is attached, operate the relevant
pump in “HAND/ON” mode and check the volume flow
display on the SolvisControl. Set the quantity per impulse
(impulse rate), if necessary. . . . . . . . . . . . . . .page 30

are connected, check the opening direction at the mixer
module as follows:
Open the “Outputs” submenu in the main menu. Now
turn the rotary wheel until “AUTO/OFF” or “AUTO/ON”
is selected for the “Mix Heat Cyc1” output (if a second
heating circuit is connected, do the same for “Mix Heat
Cyc2”). Set this entry to “HAND” by pressing, turning
and pressing the rotary wheel. Now move the pointer
to the entry “op: OFF” (figure on right ) and press the
rotary wheel. The motor should now open the mixer as
long as the rotary wheel is pressed. If an incorrect run
occurs at plug “SM 1” or “SM 2”, swap the “op” and
“cl” connections (s. section “Wiring diagram Solvis-
Control control board”, p. 66).
Switch the outputs from “HAND” back to “AUTO”
after checking the outputs.
• Switch outputs to “AUTO”>:
Check that all outputs are set to “AUTO” to ensure the
fault-free functioning of the controller. Simply look at the
top line in the display field (see figure on right). If you
see a hand symbol below one of the numbers
(= numbers of outputs), the respective output is set to
manual mode and must be switched to automatic mode.
In the figure on the right output 6 and 7 (solar pumps)
are in manual mode and must be switched to “AUTO”
if collectors are connected.
In the main menu, select the “Outputs” menu item.
Select the operating status of the relevant output
(e.g. “solar pump”). Set the “AUTO/...” operating
status by pressing and turning the rotary wheel.
Press again to save the operating mode. Use the

9.2.2 Possible settings
1. Setting the heating program:
Various operating modes can be set for each heating
circuit:
Turn the rotary wheel until “OPERAT.: TIME/AUTO”
(see figure on right) is selected with the pointer. Set
the required mode by pressing, turning and pressing
the rotary wheel again.
Explanation of heating programs:
a) “TIME/AUTO” or “RAS”: If a room sensor is con-
nected, you activate it with the “RAS” setting.
At the room sensor, you can select the following
heating programs: “AUTO/TIME”, “NORMAL”,
“LOWERED” and “STANDBY”. With “TIME/AUTO”
The system automatically changes from normal to
lowering mode according to the set heating time
(see following page). The current operating mode is
then displayed as “NORMAL” or “LOWER” in the line
below. The flow temperature is reduced in lowering
mode. This results from the parallel movement
of the heating curve by the difference of
“T.Room.NORMAL” to “T.Room.LOWER”. In addition,
the heating pump is switched off in lowering mode
and the flow temperature is set to 5°C when the
outdoor temperature is above 10°C (factory
setting). For more details, see section
“4. Setting possibilities SWITCH-OFF

3. Setting the heat curve:
Call: “HEAT CURVE”: in the menu section “HEAT CIR.1”
of the function overview.
A systematic procedure is required to precisely set the
correct heating curve. Proceed as follows:
First open all radiator valves completely.
Set the slope of the heating curve according to one
of the tables on page 37 or 38. If a room cannot be
brought to the required room temperature despite the
fully opened heating valves, the radiator temperature is
too low and the target room temperature in the relevant
time windows must be increased at the SolvisControl
system controller. If all heated rooms are too warm, the
target room temperature in the time windows must be
lowered a little. If some rooms have the correct temperature and others are too warm, the radiator valves in
the rooms that are too warm must be closed some
more. Change the slope of the heating curve if the
target room temperature has to be continually adjusted
(page 21).
What is a heating curve?
The heating curve specifies how high the flow temperature must be for a measured outdoor temperature so
that the rooms can be heated to the required temperature. The controller can keep the temperature in the
heated rooms constant, regardless of the current
outdoor temperature. The controller distinguishes
between two different representations of the heating
curve. You can set it to “Slope” or “Temp.”:
In the heating curve menu turn the rotary wheel
until “HEAT CURVE: Slope” (figure on right) is
selected with the pointer. The form of representation can be changed by pressing and turning the
rotary wheel until the required value (“Slope” or
“Temp.”) appears and then pressing it again.

The differences between these two representations
are explained on the following pages.
Which setting options for the heating curve are
there?
You can increase the target room temperature in the
time windows at your SolvisControl. The heating curve
is shifted parallel to higher flow temperatures, i.e. for
the same outdoor temperature, the flow temperature
is increased and the rooms can be heated to a warmer
temperature.
Secondly, the slope of the heating curve can be
changed.
Every heating system requires an appropriate heating
curve setting due to the special properties of the
heating system and the building to be heated.

“Functions” Menu Overview
Setting the heating curve in “Temp.” mode.
The “Temp.” mode is used in the same manner as the
heating curves. The heating curves are selected using
a target flow (“pre-run”) temperature of 20°C and
outdoor temperature of 20°C and adjustable target
flow (“pre-run”) temperature of -20°C (figure on right).
The curvature can also be influenced by the point
adjustable target flow temperature for an outdoor
temperature of +10°C (figure in center).
The target flow temperature derived from the heating
curve are limited by the two values “T.Pre.Max” and

Setting the flow temperature limits
“T.Pre.MAX” and “T.Pre.MIN” limit the flow temperature:
The heating pump switches off when the calculated flow
(“pre-run”) temperature is lower than “T.Pre.MIN”. If the
calculated flow temperature is higher than “T.Pre.MAX”,
“T.Pre.MAX” is set as the flow temperature. This
ensures that overheating does not occur (which is
required for underfloor heating). Of course, thermostatic
flow temperature limiters must be installed where they
are prescribed.

• “Outside temp.” (see figure on right): The flow
temperature will be kept between “T.Pre.MIN” and
“T.Pre.MAX” depending on the outside temperature,
as described on pages 36ff.
You may have to change the slope and the parallel
shift (= target room temperature) of the heating
curve (page 37).
• “Fixed value” (figure center right): The flow tempera-
ture is controlled in normal mode at “T.Pre.-20°C”
and in lowering mode at “T.Pre.+10°C”. When “Fixed
value” has been selected (figure bottom right), the
mode of the heating curve automatically changes
from “Slope” to “Temp.” (temperature). The values
for “Room Influenc” and “Increasing on Start” are
then irrelevant. This setting is only permitted in
exceptional cases according to heating system
regulations.

4. “SWITCH-OFF COND.:” settings
You can determine when the heating circuit pump is to
be switched off in the switch-off condition menu (figure
on right). In order to set the switch-off conditions, the
controller must be in the “Technician” operating mode.
a) “T.Room”, room influence: The first switch-off con-
dition of the heating circuit (room temperature is
higher than target room temperature) is set to “no”
at the factory, because no room sensor is provided
for this system.
b) “T.Pre”, flow influence: In the second switch-off
condition, the controller switches off the heating
circuit when the flow target temperature determined
using the heating curve is lower than the set
minimum flow temperature “T.Pre.MIN”. This function is activated and set with a hysteresis of 2 K at
the factory. This means that the heating circuit is
switched on again when the target flow (“pre-run”)
temperature is higher than the set minimum flow
(“pre-run”) temperature “T.Pre.MIN” plus 2K.
Example for the activated switch-off condition:
Heating circuit 1 is within a time window with
“T.Room.NORMAL” = 20°C and “T.Pre.MIN” = 20°C.
The heating pump is switched off if the flow temperature (determined with the outside temperature and
the heating curve) is lower than 20°C. It is switched
on again starting at a target flow temperature of
22°C.
c) “T.Out”, outdoor temperature influence in normal
mode (summer/winter switch): You can use
“T.Out.MAX” to set the outdoor temperature at
which the heating circuit is switched off. The
average outdoor temperature is calculated over
30 minutes. The function is activated in the factory
and “T.Out.MAX” is 17°C. This means the heating
circuit is switched off when the outside temperature
is greater than 17°C + 2 K = 19°C. Hysteresis was
set to 2 Kelvin at the factory, which means the
heating circuit will not switch back on unless
the median outside temperature is less than
“T.Out.MAX” (= 17°C).
An example for the activated switch-off condition:
Heating circuit 1 is within a time window with
“T.Room.NORMAL” = 20°C, the heating pump is
switched off if the median outside temperature is
19.1°C or more. It is turned back on when the
median outside temperature falls to 17°C.

d) “T.Out”, outdoor temperature influence in lowering
mode: Use “T.Out.MIN” to specify the outdoor tem-
perature at which the heating circuit pump is to be
switched off during lowering mode. This function is
activated and “T.Out.MIN” is set to 10°C with a hysteresis of 2 K at the factory.
An example for active switch-off condition:
Heating circuit 1 is in lowering mode, and the
heating pump switches off if the current outdoor
temperature exceeds 12°C. It is turned on again
when the outside temperature drops below 10°C.
Depending on the insulation of the house,
you may want to set “T.Out.MIN”:
- poor insulation: up to 15°C
- good insulation: less than 10°C.
e) Finally, in the last line, set how you want the con-
troller to control the mixer in the heating circuit when
the heating circuit pump is switched off. Options:
Mixer set to “unchanged”, “control”, “closed”
(factory setting) or “open”.

same explanations apply as in section 9.2. However, you
cannot connect a room sensor to heating circuit 2 (contrary
to what is written there). The following inputs and outputs
are used for the second heating circuit: Outputs 4 (heating

9.4 Hot water requirement function “WW_REQ.1”
Description: This function controls the hot water heating of
your system. All factory settings enable convenient water
heating according to the hygienic continuous flow principle.
• “T.WW.ACT”: The temperature at S1 (buffer top).
Other parameters are explained in the section “Possible
settings”.
• “TIME PROG”: It is used to call up the time program
with the time windows for auxiliary heating of the hot
water buffer area to generate hot drinking water. The
factory settings are specified in the upper table on
page 17. Outside of these times, hot drinking water can
only be drawn off until the hot water buffer has cooled
down.
Possible settings:
• “T.WW.NOM”: for setting the individual target hot water
temperature, factory setting: 48°C.
The primary side of the system for water heating is
limited by a thermal mixing valve to 65°C. This is
why the target hot water temperature cannot be
higher than 55°C.

The lower the target hot water temperature, the
more energy you save. One degree lower results
in an increased solar coverage of approx. 1%.
Legionella are not a problem here as the hot water
is always freshly generated. If you chiefly take
showers, you can set the temperature to 42 to
44°C, depending on the insulation and length of the
hot water pipes. If you chiefly take baths, the temperature should be around 46 to 48°C.
In the Function overview, turn the rotary wheel until the
pointer is at “T.WW.NOM” (figure bottom right). Now
change the value by pressing, turning and pressing the
rotary wheel again.
• “T.WW.MIN”: The hot water minimum temperature is the
target value for the hot water temperature outside of the
auxiliary heating times. The hot water buffer temperature
is kept at 12 to 15°C for the lowest setting (0°C, factory
setting). This saves the most energy.

9.7 Circulation control function “CIRCU”
Description: When you have long hot water pipes, the
water needs to run for a while before it comes out hot
at the tap. This wastes precious drinking water.
You can remedy the situation with an additional water pipe,
called a circulation pipe, which circulates the drinking
water until it reaches its target temperature at the tap.
The factory settings ensure that you can immediately
get hot water from the tap when you need it.
• “OPERAT”: Do not change the “Time” controller mode
for the circulation pump. The “Time” controller mode
controls the circulation pump using a time-dependent
temperature controller. Hot water is immediately available at the tap at the times that you set. Outside of
those time windows, the circulation pump is always
switched off.
• “T.CR.ACT”: The current temperature of the drinking
water in the circulation return pipe.
• “T.CR.NOM”: Target temperature, corresponds to
T.WW.NOM.
The pump switches on when:
a) One of the time blocks is active and
b) the circulation sensor S11 has cooled to less than the
target temperature “T.CR.NOM” by the value “DIFF.ON”.
Example: According to the factory settings, “DIFF.ON” =
-12 K, “DIFF.OFF” = -9.0 K and “T.CR.NOM” = 48°C.
At: “T.CR.ACT” = 48 – 12 = 36°C, the circulation pump
switches on, and at: “T.CR.ACT” = 48 – 9 = 39°C, it
switches back off.
• “TIME PROG.”: You can set time windows to control the
circulation pump here. Outside of these times, the pump
will not operate and circulation will not take place.

To use this function, a volume flow sensor (VSM-SC,
item no.: 09499, please order separately) must be
installed in the solar line. Otherwise, “FLOW”,
“POWER” and “HEAT QUANT” will always be zero.
You may also use a different volume flow sensor with
impulse output. The volume in litre/impulse must then
be set correctly in the SolvisControl (page 30).
• “Status”: “CALIBRATED” or “UNCALIBRATED”.
We use extremely accurate temperature sensors for
measuring solar flow and solar return temperatures
(Pt 1000), which means calibration is not necessary.
• “FROST PROTECTION”: The amount of antifreeze in the
secondary solar circuit is fixed at 0%. The volume flow
sensor is located in the secondary side of the plate heat
exchanger (“PHU”). This circuit between the storage tank
and PHE is run using heating water.
• “T.Pre-run:” Flow temperature in secondary solar circuit,
sensor S5, “T.Solar Pre2”. Temperature of the heating
water after running through the plate heat exchanger.
The stratified charger stores the heated heating water
in the layer with the same temperature.

9.9 REQ. HEATING function
When necessary, the function “REQ. HEATING” will send a
requirement signal to the automatic firing system of the
boiler.
• “REQ. TEMPERATURE”:
- “T.Req.ACT.”: Current upper temperature in heating buffer
- “T.Req.NOM”: Target temperature for heat requirement
(= greatest flow (pre-run) temperature of heating circuits).
The burner starts when the actual temperature at the upper
heating buffer is lower than the flow (pre-run) temperature
“T.Req.NOM” increased by “DIFF.ON” (= 1 K).
• “SHUT-OFF TEMPERATURE”:
- “T. Off ACTUAL”: Current temperature in the lower heating
buffer – “T.OFF TARGET”: Target temperature corresponds
to “T.Req.NOM”.
The burner stops when the actual temperature in the lower
heating buffer is higher than the greatest flow (pre-run) temperature “T.OFF TARGET” by “DIFF.OFF” (= 0 K).
Example: “T.Req.NOM” = 47°C, “DIFF.ON” = 1 K and
“DIFF.OFF” = 0 K (factory setting). The temperature of the
heating buffer is at least 47°C (lower) and 48°C (upper).

Heating requirement menu overview
• “Base Temperature”: If the boiler temperature “T.Req.ACT”
drops below “T.Req.MIN” (= 0°C), the burner switches on
for “Minimum Runtime Burner” = 90 seconds.
“ECO OPERAT.:”
This function enables you to save even more energy.
You accept the fact that it might remain a bit colder
for a certain amount of time and that the burner
stays off, meaning only solar energy can be used.
• “Undercoverage”: Percentage of the flow (pre-run) for a
tolerated lowering of the same by 1 hour. Starting with full
heating operation, the burner switches off and solar heat
has priority. It switches back on when the target flow
temperature drops below the requirement threshold.
The course of the requirement threshold is calculated as
follows:
dT x dt = const = undercoverage x target flow (“pre-run”)
temperature, and is shown in the diagram below. “dT”
is the difference in temperature for the requirement
threshold and “dt” is the time change.
Example: You accept an undercoverage of 20% of the flow
temperature, meaning that for one hour, 40°C instead of
50°C suffices. If the current flow temperature is 30°C,
for example, the burner would resume operation after
30 minutes. If the flow temperature drops below 30°C,
the burner would start immediately. If during those 30
minutes solar energy warms up the tank enough to bring
the flow (“pre-run”) temperature up to 40°C, the burner
would restart after an hour. If the temperature were to
reach 45°C, the burner would remain off for two hours,
and so forth.

10.1 Checking functions
You can check functions quickly with the “FUNCTION
STATUS” subfunction that is available at the start of most
function menus (figure on right).
The following example explains the “FUNCTION STATUS”
menu using heating circuit 1 as an example:
• “ENABLE HEAT CIR.1/PUMP/MIXER”: If the line has a
check mark (✓), it means that the function can control
this object. In the figure below, for example, the pump is
not enabled. This can be due to many reasons. To find
out which ones, proceed to the next step by looking at
the input variables. For example, it shows that a hot
water priority is defined, which means the pump is
blocked when the hot water buffer requires auxiliary
heating. In the next step, you would need to determine
whether there is a requirement arising from the hot
water.
• “Status” of “HEAT CIRCUIT PUMP”/”MIXER”: Tells
the status of the output as controlled by the function.
Compare this information with the display of the statuses of the outputs in the first line (no. 3 is highlighted
in black: Pump “on” otherwise “off”, no. 8 black:
Mixer “op.”, no. 9 black: Mixer “cl.”, otherwise “off”).
Example: If the “HEAT CIR.1” function and the pump are
both enabled, “Status” of the heating circuit pump will
show whether or not the pump is operating. However, if
the “HEAT CIR.1” function is not enabled, (for example,
because the “Floor Dry” function is active), the pump
status will always be off, regardless of whether it was
activated by the “Floor Dry” function or not.
• “FROST PROTECTION MODE”: If the line has a check
mark (✓), it means that the respective heating circuit is
in frost protection mode.
• “LIMIT T.Pre.NOM”: A check mark (✓) behind the
queries means that the target flow (“pre-run”) temperature is within the limits “T.Pre.MIN” and “T.Pre.MAX”.
• “SWITCH-OFF COND.”: Here, the queries of the switch-
off conditions from the respective heating circuit are
given inversely, which means if all switch-off conditions
are met, the pump would not be shut off. Only the last
query “LOWERING MODE and T.Out.: ACT. < MIN” is evaluated when the heating circuit is in lowering mode.

10.2 Frequently asked questions about SolvisControl
10.2.1 How are the solar pumps controlled?
When does the primary solar circuit pump switch on?
Whenever the collector temperature (“T.Collector”, input 8)
is higher than the temperature in the lower part of the
storage tank (“T.Ref.Sto”, input 3) by SolvisControl set
switch-on difference (“DIFF.ON”). This only happens in the
“AUTO” operating function. “DIFF.ON” should be the same
as the switch-off difference “DIFF.OFF” plus a hysteresis
of approx. 5 K.
Explanation:
You should enter a hysteresis so that the pump does not
switch off immediately when the value drops below 15 K.
Factory setting on the SolvisControl: “DIFF.OFF” = 10 K
and “DIFF.ON” = 15 K.
Switch-on condition:
Solar circuit ON:
“T.Collector” – “T.Ref.Sto” ≥ “DIFF.ON”
When does the primary solar circuit pump switch off?
Whenever the “Collector temperature – Reference temperature” difference exceeds the set value of “DIFF.OFF” (factory
setting 10 K) on the controller.
Switch-off condition:
Solar circuit OFF: “T.Collector” – “T.Ref.Sto” < “DIFF.OFF”
How is the secondary solar circuit pump controlled ?
The pump in the secondary solar circuit is switched on
when the pump of the primary circuit switches on and the
flow (pre-run) temperature of the primary circuit T
VL1
(S7)
is higher than the temperature in the lower part of the
storage tank “T.Ref.Sto” plus a switch-on temperature
difference of 8 K. It is turned off when the primary solar
circuit pump switches off or T
< “T.Ref.Sto” + 5 K.
VL1
The speed is controlled so that the flow (pre-run) temperature of the secondary solar circuit T
(figure below)
VL2
is 7 K higher than the hot water target temperature
(T.WW.NOM). A frost protection function ensures that the
heat exchanger does not freeze in winter.

Principle of the solar heat transfer station
We recommend that “DIFF.OFF” = 10 K and
for “DIFF.ON” = “DIFF.OFF” + 5 K.
How does the speed control work?
The primary solar pump has a speed control. The flow is
set in such a way as to make water in the tank reach the
hot water standby temperature as quickly as possible
(12 K above target hot water temperature). Higher temperatures are not advisable, as they would make the collector
less effective. The pump runs at its highest speed for
90 seconds, then it drops down to the target temperature
on the collector sensor (S8). This is the quickest way to
raise the collector operating temperature. The collectors
reach an optimal minimum temperature that can be held
constant by raising or lowering the flow when temperatures
rise or fall. Higher temperatures can also occur when the
maximum speed has been reached. Do not reduce the
flow in the solar circuit; the flow meter must be completely
open.
This controller guarantees that the collectors warm up
quickly when the sun begins to shine. This, together with
the stratified charger, brings the tank to standby more
quickly. Compared with conventional systems, the burner
needs to provide less auxiliary heat.
When does the safety function deploy?
The maximum tank temperatures “T.Lim.MAX” (upper) and
“T.Ref.MAX” (lower) are factory preset to 95°C and 90°C.
Specifying a maximum tank temperature allows for a twofold safety function, meaning the solar pump switches off
when:
a) The temperature at the “T.WW.Buffer” (input 1) sensor
is greater than the maximum temperature “T.Lim.MAX”
or
b) The temperature at the “T.Ref.Sto” (input 3) sensor is
greater than “T.Ref.MAX”
A hysteresis (factory setting 3 K) is taken into account so
that the solar pump does not switch back on immediately
if “T.WW.Buffer” drops below its set value. The solar pump
switches back on when:
a) “T.WW.Buffer” < “T.Lim.MAX” – “Hysteresis”
or
b) “T.Ref.Sto” < “T.Ref.MAX” – “Hysteresis”.

10.2.2 How is the hot water pump controlled?
Hot water is produced in accordance with the continuous
flow principle using an external plate heat exchanger
(PHE). You can use SolvisControl to adjust the target
hot water temperature.
The “T.Warm Water” sensor (input 2) controls the hot
water exit temperature. To control it quickly, you must
use this temperature sensor as an immersion sensor in
the hot water output of the plate heat exchanger. Our
hot water station, WWS-36, is set up like that when it is
delivered.
10.2.3 How is auxiliary heating controlled?
If the solar system cannot provide enough energy, auxiliary
heating for the hot water buffer layer must come from an
external boiler. A requirement signal is sent to the automatic
firing system for this purpose. If you have an external boiler,
the boiler pump will be controlled automatically as well.
SolvisControl has four different functions that can require
auxiliary heating:
When you open the hot water tap, the control switches on
the hot water pump at output A2
SolvisControl controls the speed of the A2 hot water pump
based on temperature so that the target hot water temperature is constantly available when you open the tap.
1. Function: “10: Requirement WW”, “WW_REQ.1”
If the temperature at sensor S1 (“T.WW.Buffer”) drops
below the set temperature increase of 12 K to the target
hot water temperature, the boiler switches to service
water priority and loads this section of the tank.
2. Function: “11: Requirement WW”, “WW_REQ.2”
If the temperature at sensor S9 (“T.H. Buffer U”) drops
below the set temperature increase of 12 K to the target
warm water temperature, the boiler switches to service
water priority and loads this section of the tank.
3. Function: “21: Requirement Heating”, “HEAT_REQ”
The heating buffer layer lies below the warm water buffer
layer. If the temperature in the upper layer (sensor S4,
“T.H. Buffer U”) is lower than the target flow (“pre-run”)
temperature of the heating circuit plus the switch-on
temperature difference (“DIFF.ON” = 1 K), heat will be
requested. The boiler switches off when the temperature
in the lower layer of the heating buffer (sensor S9, “T.H.
Buffer U”) is higher than the target flow temperature plus
the switch-off temperature difference (“DIFF.OFF” = 0.1 K).
4. Function: “23: Requirement WW”, “WW_REQ.3”
If the temperature at the sensor heating buffer upper
“Temp. upper heating buffer” drops below the set
increase of 10 K to the target swimming pool temperature, the heating buffer is loaded.

Collector maximum temperature
This function protects the solar system components by
preventing the solar pump from restarting when steam
has formed in the collector.
The solar pump switches off when the temperature on
the S8 (input 8) collector sensor exceeds the maximum
collector temperature, “T.Coll.MAX”, which is set to 120°C
at the factory. The solar pump does not restart until the
collector cools below “T.Coll.MAX” minus a “hysteresis”
of 20 K (adjustable), assuming the other switch-on conditions (maximum tank limit or switch-on difference) have
been met.
You should only change “T.Coll.MAX” from 120°C
and the “hysteresis” from 20 K in exceptional
cases. To avoid accidental changes, you can only

10.3.3 Setting and checking the solar circuits
The minimum speed levels of 22 (primary circuit) and
10 (secondary circuit) ensure a minimum flow for the
greatest assumable pressure loss in the solar circuits.
If the loss of pressure in the solar circuits is small, you
should adjust the minimum speed level to save drive
energy. The maximum speed level must remain set to 30.
Professional installation is a prerequisite for setting
the solar pump. Both solar circuits (primary and secondary circuit) must be professionally flushed and
bled of air, and their safety equipment must be properly installed. Install the sensors as described in
the installation instruction for the solar heat transfer
station (Solvis document no.: P 40 or P 42).
Set the speed control on both solar pumps to level three
and open the adjusting valve in the primary circuit completely (delivery state).
Setting the primary circuit:
• Determine the minimum speed of the solar pump in the
primary circuit as follows:
- Calculating the minimum flow:
Absorber surface area [m²] x 10 [l/m² h]
60 [min/h]
- Determining the minimum speed:
Switch output 6 to “HAND/ON” (figure on right),
Lower the speed until the calculated volume flow has set.
This speed is the minimum speed level. Switch output 6
back to “AUTO”.
• Setting the minimum speed level:
In the “Technician” operating mode (page 25), set the
minimum speed level as follows:
Press the “SERVICE” button in the function overview
to go to the main menu. In the main menu, select the
“Functions” entry by turning and pressing the rotary
wheel. In the functions menu that has just been displayed, select the “PID SOLAR1 PAR?” entry under “3:
PID CONTROL”. In the PID control menu, turn the rotary
wheel until the pointer is at “Minimal: 22” (figure on

required number is displayed, and press it again to set
the minimum speed level. Press the “BACK” button
three times to return to the function overview.

10.3.4 “START FUNCTION”
Auxiliary start function for evacuated tube collectors
Activate this function only when use evacuated tube collectors from SolvisLuna. Sometimes heated heat transfer fluid
covers the sensors on these collectors too late, meaning
the solar pump starts too late. This function briefly activates the solar pump at specific intervals, transporting the
contents of the collector to the sensor to determine the
actual temperature for normal operation. To save energy,
flush intervals only occur when the weather makes them
necessary. The controller determines whether this is the
case based on the temperature measured at the collector.
You can activate this function beginning at “Technician”
(page 25) operating mode as follows:

11.1 Information on SolvisControl system controller
11.1.1 “Inputs” menu item
The sensors on the inputs are described here. The positions of the sensors are shown in the system diagrams
in the Appendix (p. 67f). The following measured quantities (“display name”/sensor designation) are displayed:
1: Hot water buffer temperature (“T.WW.Buffer”/S1)
The sensor is in the upper third of the storage tank, and
it displays the temperature of the water in that location
(hot water buffer). It must be at least 10 K to 12 K
above the target hot water temperature to guarantee
that the water that comes out of the tap reaches the set
hot water temperature. If that is not the case, you must
check (p. 43) the “DIFF.ON” temperature increase. In the
second step, check whether the auxiliary heating provided by the boiler is working correctly.
2: Hot water temperature (“T.Warm Water”/S2)
The sensor is directly in the output of the hot water
heat exchanger. It displays the temperature of the
heated drinking water after it has passed through the
heat exchanger.
3: Storage tank reference temperature (“T.Ref.Sto”/S3)
The sensor is at the bottom of the tank. It displays the
temperature used to switch on the solar pump when
there is a difference between the collector and the
storage tank (S8 – S3).
4: Upper heating buffer (“Temp. upper heating buffer”/S4)
The sensor is located at the top of the buffer below the
hot water buffer sensor S1. It limits the upper layer of
the tank, which holds heating water required for room
heating. The temperature it displays should be at least
as high as the higher target flow (“pre-run”) temperature
in the heating circuits.
5: Solar flow (“T.Solar Pre2”/S5)
Temperature sensor in the flow of the secondary solar
circuit (plate heat exchanger storage tank) necessary for
recording solar yields.
6: Solar return (“T.Solar Ret2”/S6)
Temperature sensor in the return of the secondary solar
circuit (plate heat exchanger storage tank), required for
recording solar yields.
7: Solar flow (“T.Solar Pre1”/S7)
The sensor is located in the flow (from the collector)
of the primary solar circuit.
8: Collector temperature (“T.Collector”/S8)
It displays the temperature measured at the hottest
part of the collector (at the collector outlet).
9: Lower heating buffer (“T.H.Buffer U”/S9)
The sensor is located about in the middle of the tank.
It limits the lower layer of the tank, which holds heating
water required for room heating. If the hot water demand
is particularly high at certain time, this sensor can
increase the hot water buffer area.
10: Outdoor temperature (“Outside temp”/S10)
Shows the outdoor temperature. The sensor should be
mounted roughly 2 meters above the ground on one of
the building’s exterior walls that does not receive direct
sunlight (such as the north side).
11: Circulation temperature (“T.Cir.Ret”/S11)
The temperature measured in the circulation pipe (if
applicable). The sensor must be mounted on the return
of the circulation pipe, between the pipe and the insulation. It should not be directly next to the pump.
12: Flow (“pre-run”) temp. Heating circuit
(“T.Heat.Cir.P1”/S12)
Temperature sensor on the flow of mixed heating circuit 1.
It uses the mixer to control the flow temperature.
13: Flow (“pre-run”) temp. Heating circuit
(“T.Heat.Cir.P2”/S13)
Temperature sensor on the flow of mixed heating circuit 2.
It uses the mixer to control the flow temperature.
14: Return temperature of the hot water heat exchanger
(“T.WW.Ret”/S14)
The sensor is located on the return of the primary
circuit of the hot water heat exchanger. It displays the
temperature of the storage tank water used for generating hot water when it returns to the tank.
15: Flow measurement (“Solar Flow.2”/S15)
Optional. display of the volume flow in the secondary
solar in l/h. The volume flow meter is located in the
return of the secondary solar circuit.
16: Room temperature (“T.Room1”/S16), alternatively:
Swimming pool temperature (“T. swimming
pool”/S16)
Connection of room sensor or temperature sensor for
swimming pool heating as immersion sensor in the
sequence of the filter circuit.

Appendix
11.6 Circuitry of the burner requirement
1. Version
Auxiliary heating contact on boiler requires 230 V
voltage signal:
In this case, you have to put a wire jumper between the
“L” and “T1” contacts on output 12 of the SolvisControl
mains circuit board (figure on right).
In addition to the safety equipment in the boiler, you can
install an additional safety temperature monitor or safety
temperature limiter at the “ST” connection.
Never use the 230 V voltage from the T2 contact
as a voltage supply for the boiler’s automatic firing
system. The safety measures in the boiler would
be by-passed and there would be no switch-off
safety in case of a malfunction.
2. Version
Auxiliary heating contact on boiler requires a floating
contact:
Control board
REQ. Burner
Boiler connection with 230 V voltage signal
Control board
Boiler or
sensor switch
module
You must remove the wire jumper mounted on the “ST”
contact (figure on right). This keeps the switch contact
between the T1 and T2 contacts a sufficient distance
away from the 230 V strip conductors.
3. Version
Modulating boiler with temperature controlled by
0-10 V interface:
The boiler connection for modulating boilers
with (0 to 10 V) can be implemented using analogue
output A15 (see page 70).

Appendix
Transfer of the boiler flow temperature to modulating boilers
The required boiler flow temperature is output as an
analogue voltage signal (0 to 10 volts) with function 39
via analogue output A15 to a modulating boiler.
Analogue output 15 must be set with the corresponding
scaling in the “Outputs” menu according to boiler type
and manufacturer.
Standard settings for scaling:
The factory-set controller scaling is the scaling for
a standard boiler
150 scale divisions (15°C) is assigned
0.6 V and 900 scale divisions (90°C) is assigned 10.0 V.
The relationship of the voltage signal to the boiler flow
temperature is shown in the adjacent diagram.
Setting the scaling:
The appropriate values must be taken from the specific
data provided by the boiler manufacturer, as shown in the
adjacent sample table or the diagram above.

Use the adjacent table to enter the values determined by
the boiler manufacturer.
The scaling is then set according to these values.
You can only change the scaling in the “Expert” operating
mode. To do so, use (see page 26).
In the function overview, press the “SERVICE” button. In
the main menu, select the “Outputs” entry by turning and
pressing the rotary wheel. In the Outputs menu, position
the pointer on “PAR?” beneath the entry “15: Analog
output” and press the rotary wheel. In the menu that then
appears, turn the rotary wheel until the pointer is at the
corresponding parameter values (figure on right). Press
and turn the rotary wheel to change parameters. Press the
rotary wheel again to save the value that you set. Press
the “BACK” button several times to return to the function
overview.
