Principle of operation
DCBWA-SSseriesconsistsofaheatpump,waterheater,
electrical module, circulation pumps and a control sys-
tem.DCBWA-SSseriesisconnectedtothecollectorand
heating medium circuits.
The heat from the heat source (rock,
soil, lake) is taken
up via a closed collector system in which a mixture of
water and antifreeze circulates. Groundwater can also
be used as a heat source, but this requires an inter-
vening heat exchanger.
The brine emits its heat to the refrigerant in the heat
pump’s evaporator. It then vaporises and is com-
pressed in the compressor. The refrigerant, the tem-
perature of which has now been raised, is passed to
the condenser where it gives off its energy to the heat-
ing medium circuit and, if necessary, to the water
heater. After the condenser there is a built-in electrical
module which cuts in if there is a high demand.
The heating medium side and
the hot water side must be fit-
ted with the necessary safety
equipment in accordance with
the applicable regulations.

Unit Description
In order to get the best results from the climate system DC BWA-SS series you should read through the
section For the System manager in these Installation and Maintenance instructions.
DC BWA-SS series is a climate system for heating houses and apartment buildings as well as industrial
properties.
Ground, rock or lakes can be used as the heat exchange source.
DC BWA-SS series
is a complete heating installation for heating and hot water .
It is fitted with new design on the market to be developed specifically for heat pumps. A new evaporator enables
a
new and impr oved cir culation system for the r efrigerant. The heat pump has an integrated 150 or 200 litr e water
tank and
an immer sion heater . The T ap W ater Stratification system impr oves the ef ficiency of heat transfer by keeping
the water in
distinct thermal layers in the water tank.
The unit is fitted with a r egulating computer , which is contr olled over a graphic display unit.
Heat is distributed thr oughout the house over a hydr onic heating system r eferr ed to as low temperatur e
system with a maximal water temperatur e to radiators (Feed line temperatur e) of 65°C. Most of the heating
demand is taken car e of by the heat pump (compressor unit), the auxiliary heater being star ted only when
demands exceed available heat pump capacity .
DC BWA-SS series consists of five main components:
a. Heat Pump Unit
Rotary or Scr oll-compr essor
Stainless steel heat exchangers
Cir culation pumps for Brine system (brine) and heating systems
V alves and safety equipment for r efrigerant system, complete with necessary electric components
b. W ater Heater
150 or 200 litr e
Lined
with copper sheet against corr osion or made of stainless steel
Maintenance fr ee as no anode is used
c. Reversing V alve
Opening or closing the connection to water heater accor ding to operating mode: heating or warm water
pr oduction
d. Auxiliary Heater
3 / 6 / 9 kW electric heating element
Three-step capacity contr ol
Fitted on Feed line
Delivers back-up heat in case of gr eat heat demand that exceeds heat pump capacity
Star ts automatically , pr ovided operating mode “AUTO” has been selected
e. Regulating Equipment
The r egulating system contr ols heat pump components (compressor , cir culation pumps, auxiliary heater and
r eversing valve). Based on data r eceived fr om sensors, it star ts or stops heat pump operation and determines
whether he a ting or warm water shall be pr oduced. The system consists of:
Control computer with graphic display unit
T emperatur e sensors (outside air ,room, Feed line, r eturn line, and Brine system)

System description 4
Principle of heat pump
A heat pump can exploit the ener gy contained in natural heat sour ces. Or , to put it dif fer ently , the heat
pump ”collects” heat ener gy fr om the heat sour ce. This makes the heat pump a very environmentally friendly and
economically sound alternative for space heating.
a. A hose filled with liquid (Brine system) is immersed into a lake, dug into the gr ound or sunk into the r ock. The
Brine sytem absorbs the heat ener gy of the heat source so that the temperatur e of the water cir culating in
the hose is raised a few degr ees.
b The Brine system is cir culated to the heat pump’ s evaporator . Here the heat ener gy of the Brine system causes
the
r efrigerant, cir culating thr ough the evapo rator , to boil and turn into a gas – it evaporates.
c The r efrigerant, having absorbed heat ener gy , is cir culated to the compr essor wher e pr essur e and temperatur e
ar e raised.
d The r efrigerant continues to the condenser . When condensing, it r eleases heat ener gy to the heat carrier ,
cir
culating thr ough the condenser . The temperatur e of the r efrigerant sinks, and it r eturns to its liquid state.
e The heat ener gy r eleased is carried by the heating cir cuit to water heater and radiator or floor heating systems.
f
At last the r efrigerant is led thr ough the expansion valve, wher e its pr essur e is r educed, and then con tinues to
the
evaporator
.
The pr ocess is r estar ted.
The heat pump has three separate liquid circuits
Brine system circuit
– a water-based mixtur e (brine) transporting ener gy fr om heat source to heat pump.
Refrigerant circui
t
– cir culating inside the heat pump. Thr ough evaporation, compr ession and condensation it
absorbs ener gy fr om the Brine system and r ele ases it to the heat carrier . The r efrigerant is chlorine-fr ee.
Heating circuit
– water transporting heat ener gy to the heating system (radia tors/floor coils) and the water
heater .

Functions
The right-hand button on the control panel is used to open the desired menu.
The left-hand button is used to return to the previous menu.
The up and down buttons are used to navigate between the parameters of a menu.
A cursor (arrow) on the left-hand side of the display indicates which menu can be opened.
The up and down buttons are also used if you wish to increase or reduce a preset value.
The control computer is operated with the help of a user friendly menu system that is displayed on the control
panel. There is a main menu and several sub-menus accessible from the main menu. The menus are
described in detail further down.
To be able to select the desired menu and increase or reduce preset values, you will use the five buttons.
Symbols
For you to know at a glance the actual operating mode of the heat pump, one of the following symbols will be shown in the lower
part of the display depending on which part of the unit is working:
The heat pump is running.
The auxiliary heater is activated.
The figur e next to the symbol indicates
capacity step.
There is a room heating demand.

When this symbol appears, the heat pump
is not running due to external signal stop it;
heat pump will restore running as soon as
signal input again
When this symbol appears, the
compressor was not running due to
high pressure of refrigerant system;
the compressor will be stopped as soon
as water temperature over 50 °C and
refrigerant system pressure over 4.0MPA,
electrical heater will start as supplementary;
compressor will restores as soon as water
temperature less than 50 °C and refrigerant
pressure get right.
During heat pump running, if the water tank symbol twinkles once in every second, it means water tank
temperature is too low and it is in antifreezing protection. At the time warm water heating will forcibly start until
water temperature get to 20 ć, then go back to previous running mode.
NOTICE

General information for the installer
7
Current regulations require the heating installation to
be inspected before it is commissioned. The inspec-
tion must be carried out by a suitably qualified person
and should be documented. The above applies to
closed heating systems. If the heat pump is replaced,
the installation must be inspected again.
DC BWA-SS series is placed on a firm base, preferably a
concrete floor or foundation. Install DC BWA-SS series
with its back to an outside wall, ideally in a room where
noise does not matter. If this is not possible, avoid
placing it against a wall behind a bedroom or other
room where noise may be a problem. Any wall that
backs on to a bedroom should be fitted with sound
insulation. Route pipes so they are not fixed to an inter-
nal wall that backs on to a bedroom or living room.
Installation
Guideline values for collectors
Inspection of the installation
For use with 40 x 2.4 PN 6.3 PEM hose.
The length of the collector hose varies depending
on the rock /soil conditions and on the heating sys-
tem, i.e. radiators or floor heating.
Max length per collector should not exceed 400 m.
Where there is more than one collector, they must be
connected in parallel, with a means of adjusting the flow.
For surface soil heat, the hose should be buried at a
depth of about 1 metre and the distance between the
hoses should be at least 1 metres.
For several bore holes, the distance between the
holes must be at least 15m.

Factors to be taken into account when designing the
collector layout are geographical position, type of
rock/soil and cover factor of the heat pump.
When installing the collector hose ensure it rises con-
stantly towards the heat pump to avoid air pockets. If
this is not possible, install high points to vent the air.
All collector pipes in heated rooms must be insulated
against condensation. The level vessel (NK) must be
installed as the highest point in the collector system
and on the incoming pipe before the brine pump. Note
that condensation may drip from the level vessel.
Position the vessel so that this does not harm other
equipment.
As the temperature of the collector system can fall
below 0 °C it must be protected against freezing down
to -15 °C. One litre of ready mixed brine per meter of
collector hose (applies when using PEM-hose 40 x
2.4 PN 6.3) is used as a guide value when making the
volume calculation.
Details of the antifreeze used must be shown on the
level vessel.
Pipe installation must be carried out in accordance
with current norms and directives. The heat pump can
operate up to a return temperature of about 58* °C
and an outgoing temperature of about 70* °C from the
heat pump. The compressor produces up to 65* °C,
the rest is obtained using additional heating.
The other heat pumps has a max return temperature
of approximately 50 °C and an outgoing max tempera-
ture from the heat pump of approximately 60 °C.
Since the DC BWA-SS series is not fitted with shut-off
valves, these must be fitted outside of the heat pump
to make future servicing easier.
During assembly the pipes for the heat medium
and water heater and possibly hot water circulation
are routed backwards. The distance between
DC BWA-SS series and the wall ought to be 50 mm.

Shut-off valves should be installed as close to the heat
pump as possible. Fit the supplied particle filter on the
incoming pipe.
In the case of connection to an open groundwater sys-
tem, an intermediate frost-protected circuit must be
provided, because of the risk of dirt and freezing in the
evaporator. This requires an additional heat exchang-
er.
Pipe connections (collector)
The collector circuit may be connected from the left or
from the right. The lower side panels are swapped
over to suit the chosen connection option. The
enclosed connecting pipes for the brine are secured
using the clips in the punched tabs that are folded
down on the side in question.

Pipe connections
9
Pipe connections for the heat medium side are made
at the top. All required safety devices, shut-off valves
(as close to the heat pump as possible), and particle
filter (supplied) are fitted.
When connecting to a system with thermostats on all
radiators, a relief valve must be fitted, or some of the
thermostats must be removed to ensure sufficient
flow.
Pipe connections (heating
medium) The heat pump´s water heater must be fitted with the
necessary valve equipment.
Pipe connections (water heater)
The heat pump should be supplemented with an elec-
tric water heater if a bubble pool or other significant
consumer of hot water is installed. The valve coupling
in COMPACT (electrical water heater) can be divided.
The mixing valve stays in COMPACT and the remain-
ing valve coupling can be used for incoming cold
water in DC BWA-SS series.

Commissioning and adjusting
Before starting up the system, check that the heating,
collector and hot water circuits are full and thoroughly
vented. Check the pipe system for leakage.
Filling and venting the
heating medium system
Internal air vent valve, brine
Preparations
When filling the brine system mix the water with
antifreeze in an open container. The mixture should
be protected against freezing down to about -15 °C.
The brine is filled by connecting a filling pump.
1. Check the brine system for leakage.
2. Connect the filling pump and return line on the
brine's system's service connections as shown in
figure.
3. Close the valve under the level vessel.
4. Close the valve between the service connections.
5. Open the valves on the service connections.
6. Start the filling pump, and fill until there is fluid in
the return pipe.
8. The filling pump and the heat pump's brine pump
are now operational.
The fluid should circulate via the mixing container
until it emerges from the return hose without being
mixed with air.
9. Stop the filling pump and clean the particle filter.
10. Start the filling pump, open the valve between the
service connections.
11. Close the valve on the service connection's return
line. Now pressurise the system (to max 3 bar)
with the filling pump.
12. Close the valve on the service connection closest
to the level vessel.
13. Stop the filling pump.
14. Fill the level vessel with liquid up to around 2/3.
15. Open the valve below the level vessel.
16. Select the auto operating mode using the
operating mode button.
