By choosing the heat pump bravour you have decided to purchase a proven product. The unit
considers the knowledge acquired in many years of using heat pumps with state-of-the-art
technique.
The heat pumps of the SmartHeat product range distinguish themselves by an optimization
according to ecological points of view. The increasing performance as well as the use of
coolants which are very harmful to the environment are to important criteria which had been
taken into consideration when designing the units.
A high performance equals to a high ratio of regenerative environment (heat) energy, which is
used to heat living rooms - and thus complies with a little part
of CO
2
-emissions and little electrical power consumption. When operating a heat pump the
user thus contributes to the protection of our environment and saves heating cost.

3 Product description
Functional description / Application range
The compact heat pump bravour combines all main components for a heating and domestic hot water (DHW) system.
The required connection tubes can be connected from the right; the connections to the DHW system can be connect-
ed optionally from the right or left side. The integrated double-shell stainless steel tank consists of an interior DHW
tank with around 200l and a outer decoupling tank for heating water. The heat pump switches between heating and
DHW mode automatically. Priority is given to DHW production.
The SmartHeat bravour is designed for covering the heat demand without an additional electric heater. Also, an electric
heating element is integrated as standard for operating with the legionella protection mode (optionally) or heating sup-
port, if desired.
3.1 Direct expansion - Heat Pump: bravour DI
The SmartHeat bravour heat pump operates with direct evaporation of the refrigerant at the heat source and avoids
installation of a brine water circuit in this way. In this case, the refrigerant flows through many parallel polyethylene-
coated safety copper tubes and evaporates. The copper tubes have been routed over an area as ground collectors and
take the evaporation heat directly from the ground. As the refrigerant can evaporate well below freezing point, there is
no need to route the ground collector in a frost-free area. Not too deep routing has the advantage that rain, melt water
and sun radiation can become quicker effective at the ground collector (evaporator) and the energy supply is made
available as usable energy by the heat pump. The heat emitting side of the SmartHeat bravour heat pump operates with
a heat exchanger as a condenser and, in this way, heats the water for heating and domestic hot water (DHW).
3.2 Brine-water heat pump: SmartHeat bravour BW(i)
The SmartHeat bravour BW operates with an evaporator (plate heat exchanger) connected to a brine circuit. The heat
emitting side of the heat pump operates with a heat exchanger as a condenser. The geothermal collector of the BW-
system consists of PE-tubes with brine (monoethylene glycol / water mixture). These tubes are routed horizontally in
the frost-free area. An alternative (e.g. lack of space) are vertical earth probes for using geothermal heat. In both cases,
the brine is circulated as heat carrier medium by a pump through the closed circuit (brine water circuit).
The required brine circulation pump is integrated into the SmartHeat bravour, safety device and membrane expansion
tank is part of the delivery content. Insufficient heat transfer from the ground may lead to a fault and safety shut down
of the heat pump system (low pressure fault).
Provide for sufficient aeration of the heat source circuit!
3.3 Water-water heat pump: SmartHeat bravour WW(i)
The SmartHeat bravour WW is designed comparable to the bravour BW. However, instead of a brine water circuit
two groundwater wells will be connected, which supply the heat pump with groundwater. The ground water pump
and the safety devices are not installed in this case. They have to be installed in accordance to the requirements of the
ground water well. The integrated heat exchanger has to be protected against freezing of water.
Provide for sufficient aeration of the heat source circuit!

4 Options
4.1 Option R - Active cooling
General notes
The module active cooling allows you to operate your heat pump heating unit also with a cooling function in addition to
the known hot and warm water preparation functions. These cooling function enables the cooling of the building in
relation with an appropriate distribution system when it is operated in summer.
Since the module active cooling is based on the use of a cooling circuit of the heat pump there is a possibility of cooling
also at increased outside and earth temperatures.
Operation
The heat pump module active cooling is based on the reversibly designed refrigerating circuit which is integrated in the
heat pump basic unit, i.e. the heat pump is working in reverse operation. In this way it is possible to cool the heating
water in summer by means of a heat pump. The living rooms are cooled down and the ground is heated up.
Since the module active cooling is based on the use of the heat pump compressor the accruing power consumption is
comparable to the power consumption during the heating period.
Proper use
The module active cooling is an optional module for the upgrading of your heat pump device during production at the
factory. The indications for the following heat pumps are binding:
bravour serie: BW(i)/ WW(i)
The bravour module active cooling represents a firmly combined unit together
with the bravour heat pump.
The manufacturer cannot be held liable for damages and malfunctions which can
be traced back to non-observance of the operating and installation instructions.
It is necessary to install safety devices. Please request any further information at
the service hotline: +49 3843 / 2279-111.
Planning and dimensioning
For planning and dimensioning of heating and cooling spaces consider the common technical rules.
For maximum transferable cooling capacity it can be calculated with 100 W/m
2
for wall and sealing spaces. For under-
floor spaces, which are used for cooling, lower transferring capacities should be considered – at maximum 20 … 25
W/m
2
. The surface of the floor is only suitable in lower rate for cooling a building. Important for the optimum heat
transfer is the counter-flow principle inside the heat exchangers.
Remark: During cooling operation the relative humidity of the air is raising. This may lead to undershooting the dew
point temperature and therefore condensing of water at the cooled spaces. If the condensing takes place at the surface
or inside of the walls, there is the danger of damages by mildew.
Please consider that the room temperatur should not be lower than 6 K below
outside air temperature with respect to health!

Electrical connection
The module active cooling reveives the required electric power with the power supply of the heat pump. An additional
power supply is not required.
Hydraulic connection
For hydraulic connection there are no differences to heat pumps without the module active cooling. The outgoing and
backflow maintain their flow direction and are changing to cooling outflow and cooling backflow. Additional hydraulic
connections for cooling function are not available.
During start-up of the heat pump with module „Active Cooling“ take care of good
flow in heating circuit! Have a look at the data sheet of the heat pump! If this flow
is not ensured, there is the possibility of freezing of the heat exchanger, if the heat
pump operates in cooling mode during start-up unintentionally. This may lead to
damages at the heat exchanger! A flow monitoring in the heating system must be
guaranteed by the installation's operator.
During start-up with cold heating water this may be possible also at sufficient
volume flow! The water of heating circuit should not be colder than 25°C at the
first start-up!
4.2 Option N- Passive cooling
General notes
The module for externally/internal passive cooling extends the application range of your bravour heat pump by the
function to cool the building during the summer. This module is available for all bravour-models of the series BW
(brine/water) and WW (water/water). Cooling of the heating water during the summer months is achieved be transfer-
ring heat from the heating circuit to the brine circuit or the groundwater. When combining with a suitable heating and
cooling system in the house (combination of floor, wall and ceiling heating) the cooling effect can be realised for the
desired rooms. As the module for passive cooling goes without using the refrigerating circuit of the heat pump, this
gives a very reasonable possibility regarding energy consumption for cooling.
Application areas
The module for externally/internal passive cooling is based on a plate heat exchanger, as well as switching over compo-
nents (3-way-valve), which has to be installed externally/internal, and activating of cooling mode of the controller. Due
to this combination it is possible, to cool down the heating water during the summer via the plate heat exchanger. In
this case, the heat is taken up from the brine water or the ground-water and transported into the ground. The living
spaces will be cooled and the ground heated up.
By using the generously dimensioned heat exchanger, the separation of the heating water and brine water or ground-
water side continues to be kept. Filling of the heating side with antifreeze, like on the brine side, is not necessary. As
the module for passive cooling operates without using the heat pump compressor, the occurring electricity consump-
tion is low by comparison. Only the two circulating pumps of the heating side as well as the brine water side or ground-
water side will be operated.
As the function of the passive cooling is realised only via a heat exchange, a reduction of the cooling effect has to be
assumed with increasing ground or ground-water temperature. The heat, transferred into the ground will, at least in
part, be stored and taken back when need for heating starts. This leads to an improvement of the capacity and annual
operating data and can, by this, reduce the incurred electricity costs. In principle, the hot-water preparation has priority
over the cooling function.
The achievable cooling capacity cannot be given as a fixed value. It depends on the lay-out of the plate heat exchanger,
as well as dimensioning of the cooling surfaces and the brine water or well system. A reduction of the cooling capacity
during the summer can occur especially in brine water systems, as the ground continues to be heated up. With increas-
ing brine temperatures the transferable cooling capacity of the heat exchanger is decreasing.

The bravour-module for passive cooling is an optional module to upgrade your heat pump device during manufacture.
The information is applies for the following heat pumps:
bravour serie: BW(i) / WW(i)
The classic–module for passive cooling is a unit solidly connected with the classic-
heat pump.
The manufacturer will not be liable for damages and operation interruptions
caused by not observing the operating and assembly instructions.
Please request any further information as well as a commissioning log at the ser-
vice hotline: +49 3843 / 2279-111.
Planning
Observe the general technical rules for planning or lay-out of the heating and cooling surfaces. As maximum transfera-
ble cooling capacity, 100W/m² can be assumed for wall and ceiling surfaces. For floor surfaces, to be used for cooling,
smaller transfer capacities have to be assumed – at maximum 20 ... 25 W/m² - , as the energy cannot or only to a lower
degree be transferred by the floor.
Information: As the room air is also cooled down in cooling operation, the relative humidity of the air increases. This
leads, in case of undercutting the dew point temperature, to condensation of water on the cooled locations. If this
condensation occurs, for instance, on or inside the walls, there is the danger of damage to the building from moisture
and mould.
Please observe that the minimum room temperature, also for health reasons,
should not be less than 6 K below the respective outside temperature.
Electrical connection
The module for externally/internal passive cooling or the components, necessary for its operation are supplied via the
mains of the heat pump basic device. A separate supply is not necessary.
Hydraulic connection
There are no differences to the classic-heat pump series without cooling module regarding the hydraulic connection of
the heat pump device. The heating flow and return keep their flow direction and become refrigerant flow (outlet) and
return (input). Additional hydraulic connections (separate flow or return) for the cooling function do not exist.
Due to the possible mutual negative influence of the cooling operation in summer and the warming of domestic hot
water (DHW), also the planned storage systems should undergo a thorough check.
In principle, the use of combination storages cannot be recommended. Because of the large hot-water proportion and
the difficult to predict flow and layer conditions, a significant cooling of the drinking water may occur during cooling
operation. In principle, the tendency of heating water mixing and connected to this, cooling of the hot water is smaller
in double shell storages than in combination storages. However, it cannot be fully excluded. As a consequence, the
operating time of the heat pump, as well as the electricity consumption for hot-water preparation would be increased;
the cooling effect would be reduced.
For both storage variants is still valid that the connection of a solar thermal plant makes no sense if a cooling function
has to be realised. The solar plant would again heat up the cooled heating water in the lower storage region, due to
which the cooling will be significantly reduced and possibly even reversed.
Therefore, we recommend for an intended use of cooling also the use of two separate storages for hot-water prepara-
tion and as a heating buffer. A mutual influence of the cooling and hot water preparation will be avoided by this. Further
more, the possibility exists to integrate a solar thermal plant to support warming of domestic hot-water.

6 Transportation
Before delivery our products are checked if they are without damages and functional and finally they are packed.
In order that the cooling circuit and the function of compressors are not impaired it is necessary to transport the heat
pump vertically.
Imperatively avoid serious impacts. The sensitive spring-supported bearing of the compressors might get damaged.
Observe the weight of the heat pump and use appropriately dimensioned transportation means. It is recommended to
use a lift truck or a similar device in order to transport the unit to the installation place.
7 Installation
General notes
Install the heat pump in a way that the field service can easily perform commissioning and maintenance works and en-
sure free working space on all sides (refer to the recommended minimum clearances).
The installation space must be dry and frost-free and have a plane and horizontal ground. The ground must be dimen-
sioned according to the weight of the SmartHeat bravour heat pump. The connection to the heating and heat source

8 Assembly
General notes
The following connections must be made at the heat pump:
- Input/output heat source
- Flow/return heating
- Power supply
- Cold water, hot water, circulation
- Flow/return solar (option S)
Preparation
The connections for the heat pumps of the bravour series are to lead from the right side or from behind in the ma-
chine. Comprehensive hydraulic accessories such as e.g. connection kits, switching units, etc. (refer to product cata-
loguet) are available for the optimum connection in the SmartHeat system accessories. In the right housing part are
lasered circular openings which can be broken out according to need. For the line feeding the rear are located in the
rear of the machine also circular cutouts that must be sealed with the supplied insulating jacket when not in use.
The heat pumps are integrated in the heating network and for drinking water preparation it may be quite different
depending on the application. In any case it must be observed that it is necessary to work with spreading between the
flow and return from 3 – 4 K resp. 5 – 7 K on the heat source and heating side in order to attain the values indicated on
the data sheets resp. in order to avoid malfunctions. Compared to traditional incinerators of higher mass flows, i.e.
larger pipe cross sections and corresponding pump designs.
8.1 Connection at the side of the heat source
SmartHeat bravour DI
The sensor of the thermostatic expansion valve has to be removed from the tube before soldering, when connecting
the connecting line to the machine. The thermostatic expansion valve and the sensor have, absolutely, to be cooled
during soldering. After soldering, the sensor has to be reconnected to the tube at the original position.
Attention has to be paid to sufficient thermal contact.
When connecting the tying up line with the machine all corresponding EC- direc-
tives, DIN and VDE standards and regulations were kept.
SmartHeat bravour BW
Connect input/output heat source at the heat pump according to the designation.
Do not forget the safety devices and the expansion vessel when installing the heat
source!
A dirt trap should be mounted at the heat source input of the heat pump in order
to protect the evaporator against soiling. Additionally it is necessary to install a
micro air bubble separator in the heat source system.
Produce the brine before filling the system.
The brine concentration should have a frost protection of at least -15°C.
Only use anti-freeze on the basis of monoethylene glycol or propylene glycol basis.

SmartHeat bravour WW
Connect input/output heat source at the heat pump according to the designation.
Do not forget the safety devices and the expansion vessel when installing the heat
source!
A dirt trap should be mounted at the heat source input of the heat pump in order
to protect the evaporator against soiling. Additionally it is necessary to install a
micro air bubble separator in the heat source system.
The ground water which is used as heat source must comply with the minimum
requirements mentioned under item 3.
8.2 Connection of the heating system
Before connecting the heat pump to the heating system it is necessary to rinse the heating system in order to remove
possible soiling, remainders of sealing material or other materials. Accumulation of remainders in the condenser can
result in a complete failure of the heat pump. After having performed the installation of the heating system, fill, bleed
and squeeze off the heating system.
For the optimum connection comprehensive hydraulic accessories are available from the SmartHeat system, such as
e.g. connection kits, switching units, etc. If inappropriate connection material is used for the hydraulic installation strong
noise development, malfunctions or material damages might occur! The integration of the heat pump into the heating
network and for drinking water preparation may be very different depending on the respective application. The hy-
draulic connection scheme detailed in the annex shown a corresponding option.
Do not forget the safety devices and the expansion vessel when installing the heat-
ing system!
Before commissioning the heat pump, it is necessary to guarantee frost-
protection. It is necessary to make sure that the hydraulic system does not freeze
when the heat pump is switched off or fails.
The minimum heating water throughput of the heating pump must be made sure
in any operating status of the heating system.

lation connection. Optionally flexible tubes for these connections are available. They have each a length of 165cm.
On site a DHW safety device has to be installed (this is not in the delivery content). If necessary a circulation connec-
tion can be connected to the circulation system. If this is not required, the connection at the tank hast to be closed.

For installation of DHW safety device within the heat
pump a drain with siphon has to be used.
Close the circulation connection, if you do not use it.
If you set the DHW temperature with 60° or higher, on
site a safety protection against scalding has to be installed
(e.g. ESBE Serie 30MR).

8.4 Electrical connection
General notes
Work on the opened heat pump cabinet and connection box must only be carried out in dead switched status and by
an approved electrician or services technician. All components, necessary for the power supply and control, are in the
upper half of the heat pump cabinet.
The necessary cross section of the cable depends on the power consumption of the heat pump. Observe the technical
connection conditions of the corresponding energy utilities as well as the VDE 0100 and DIN EN 60204.
Make sure to apply a right rotating field when connecting the supply lines for the
main current (possibly special tariff). In case of a wrong rotating field the heat
pump does not have any output and is getting damaged.
The compressor is protected against thermal overload. The fusing and the motor
protective switch for the heat pump as well as the separator from the network
must be produced by the system builder.
In case of an extension of the sensor connection line, it is necessary to use a line
cross section of at least 0.75 mm².
Do not install the sensor cable together with the current-carrying conductions!
After installation and before commissioning of the system, it is necessary to check and document the earth conductor
resistance and the isolation resistance according to DIN VDE 0701 and DIN VDE 0702. These tests must be repeated
according to the intervals applicable on site or according to the DIN VDE regulations of the series DIN VDE 0701 and
0702 (commissioning, re-commissioning, etc.).
The terminal assignment diagram of the corresponding heat pump type applies. It
is available in the machine and at the appendix of this manual.
Responsibilities for the electrical cabling
For electrical installation of different connection, different responsibilities are applicable. Please observe the following
legal regulations:
 The local power supply company is responsible for the connection to a house connection (electricity meter).
 An electrical company approved by the power supply company is responsible fort he installation and connec-
tion of the supply line between the electricity meter, fuses, main switch, motor protective switch and terminal
box.
 Heating engineers authorizes by SmartHeat or correspondingly qualified electricians may perform the electri-
cal connection of the heat pump bravour . Further special knowledge which the installer gathers during training
at SmartHeat is required for such works.
 It must be possible to completely separate the heat pump bravour from the network and control tension via
one or, if applicable, several separate external main switches which are upstream to the terminal box. The in-
staller/operator is responsible for installing and connecting the external separator (main switch).

Electrical connections
The design of the electrical supplies and electrical main components are performed by the electrical specialized con-
tractor depending on the local conditions.
The following electrical supplies must be available at the installation site of the heat pump and can be either from the
back or the right side fed into the machine the necessary glands lie at:
Fig. heat pump controller
1-stage (fixed-speed)
1 x supply heat pump 3/ N/PE~50Hz/400V
1 x supply control voltage 1/N/PE~50Hz/230V
1 x heating coil 3/N/PE~50Hz/400V
Inverter 230 V
1 x supply heat pump 1/N/PE~50Hz/230V
1 x supply control voltage 1/N/PE~50Hz/230V
1 x heating coil 3/N/PE~50Hz/400V or
1/N/PE~50Hz/230V
Flow monitor source: The flow of the source circuit can be monitored and used for switching off the heat
pump. With water/water and air/water heat pumps, a flow switch must be used.
Non-compliance can lead to serious damage in the source area. In such a case, no li-
ability claims against SmartHeat may be invoked
 The outputs are capable of bearing maximum 1.0 A.
 Summarized the outputs must be charged at maximum 4.0 A.
 For higher connected loads uncoupling relays must be provided.
 When a residual current device (RCD) is installed upstream, this must be carried out
as universal current sensitive according to DIN-VDE 0100-530 and has to be of the
type B or B+.
