BWA-SS series
consists of five main components:
and
Brine sytem)
2.1 Heat Pump Principle
A heat pump can exploit the energy
contained in natural heat sour
ces. Or, to
put it
dif
fer
ently,
the heat
pump ”collects” heat energy from 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
energy of
the heat source so that the temperature 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
energy 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 energy, is
cir
culated
to
the compr
essor
where pressure
and temperature
are
raised.
d
The r
efrigerant continues
to
the condenser.
When condensing, it r
eleases heat
energy to
the heat carrier,
cir
culating thr
ough the condenser.
The
temperature of the r
efrigerant sinks, and it r
eturns
to
its liquid state.
e
The heat energy released 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, where
its pr
essure is reduced, and then con
tinues
to
the
evaporator.
The pr
ocess is r
estar
ted.
an immer
sion heater.
The Tap Water 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 referred to as
low temperature
system with a maximal water temperature to
radiators ( Feed line temperature) of 65°C. Most of the heating
demand is
taken care of by
the heat pump (compressor unit), the auxiliary heater being
star
ted only when
demands exceed available heat pump capacity.

Heater
BWA-SS series comes with a built-in water heater holding 150 or 200
litr
es. The temperature of
the water sent
to
the water heater is contr
olled by the r
egulating pr
essure switch and cannot be adjusted. Warm water pr
oduction is
stopped when the r
egulating pr
essure
switch r
eaches its
operating pr
essure,
which
corr
esponds
to
about 50-55°C warm
water temperature.
At r
egular intervals the water in the water heater will be heated
to as
much as 65°C
as a pr
eventive
measure
against bacteria. The pr
eset interval is 14 days. For more information, please r

Relation of outside

Feed line temperature
Outside air temperature
Most settings will be made by the installation contractor in connection with installation. Adjustments to be
made regularly by the user are the following:
• Selection of operating mode
• Adjustment of desired room temperature by changing the ROOM value.
• Adjustment of heat curve
• Adjustment of maximum and minimum values for feed line temperature
The indoor temperature should be adjusted by changing the heat curve of the installation. The control
computer determines the correct temperature of the water to be distributed to the heating system based on
the heat curve. The heat curve will be adjusted in connection with installation. It must be adapted later on,
however, to obtain a pleasant indoor temperature under any weather condition. A correct heat curve
reduces maintenance and saves energy.
The heat curve determines the feed line temperature depending on the outside air temperature. The lower
the outside air temperature, the higher the feed line temperature. In other words, the temperature of the
water feed to the radiators will increase exponentially as the outside air temperature falls.
If you select CURVE in the sub-menu named HEAT CURVE, a diagram will be displayed. It represents the
relation of outside air temperature to feed line temperature. This relation is referred to as heat curve.
• Adjustment of the value
for
HIGH T STOP or LOW T STOP
is possible. (Please r
efer
to
”Adjustment of HIGH T STOP
or LOW T STOP value” on p. 25).
.
Adjustment of the CURVE value
The heat curve will be adjusted by the CURVE value. This value indicates the feed line temperature
to the radiators at 0°C outside temperature. At outside air temperatures lower than 0°C, the water sent to
the radiators will be warmer than 40°C.
At outside temperatures higher than 0°C, the water will be colder than 40°C. When you increase the
CURVE value, the heat curve will become steeper and when you reduce it, it will become flatter.
This is the most energy and cost efficient way to set the indoor temperature and should therefore be
used for long term temperature settings. If you wish to make a temporary change of temperature, you
can simply change the ROOM value (see ”Adjustment of the ROOM value” on page21).

3.2.3 Adjustment of ROOM value
As mentioned above, you can also adjust heat curve and indoor temperature
by changing the ROOM value. If
you use ROOM value
to
adjust the heat curve, the
gradient does not change, i.e. it doesn’t become steeper or
flatter.
Instead, the
whole curve is moved by 1°C
for
every degree by
which the ROOM value is changed.
The r
elation feed line temperature to
outside air temperature
will not be affected. The feed line
temperature
will be incr
eased or r
educed by the same number of degr
ees all along the heat curve. See the
following diagram.
Adjustment of the ROOM value should only be used
for
temporary changes of the indoor temperature. For long
term settings, the CURVE value should be adjusted as this is the most energy
and cost efficient way
to
set the indoor
temperature.
For adjusting the heat curve, please r

When enter ‘Room heat’ mode, user could control compressor and electrical heater through
regulate heat curve or DM (degree minute).
under a certain ambient temperature ,the time start of compressor is determined by degree
minute(DM).
Now we are giving two situations to explain.
1. ‘start quickly’ is determined by FEED(heat curve)
Suppose now the feed water temperature is 25ć; regulate the heat curve to let the setting of water
temperature to be a higher value such as 55ć,that is FEED25(55). At that time, DM (degree
minute) decrease -30 per minute, when the DM reach -60, compressor will start right away.
(Notice: if the water temperature setting is lower than feed water temperature DM would turn
to positive number, and then compressor does not start. Of course, you also can regulate the DM to be
near the value for compressor start, such as -20.
turn it up
2. ‘start slowly’ is determined by FEED(heat curve)
Suppose now the feed water temperature is 25ć,if regulate the heat curve to let the setting of water
temperaturetobealowervaluesuchas30ć, that is FEED25(30); at that time, the DM would decrease -
10 per minute, the time to reach -60 is becoming longer, only after some time, then
compressor can start. You also can regulate the DM to be more far away from the value for compressor
start, such as (-100).

Adjustment of Part of the Heat Curve
At outdoor temperatures between -5°C and +5°C part of the heat curve may need adjusting if the indoor
temperature does not stay at the preset ROOM value. For this reason, the control system includes a
function adjusting the curve at three outside temperatures: -5°C, 0°C, +5°C. This function will allow you
to increase or reduce the feed line temperature, without affecting the heat curve, at three specific outdoor
temperatures. If, for example, the outside temperature is -5°C, the feed line temperature will
change gradually in the outdoor temperature range of 0°C to -10°C, maximum adjustment being reached
at -5°C. The diagram below shows an adjusted CURVE -5. The point of maximum adjustment is clearly
visible.
As we have seen, you can choose to adjust the heat curve at three specified out- side air temperatures:
-5°C,0°C and +5°C. The feed line temperature can be changed by plus/minus 3 degrees.
When outdoor ambient temperature is 5ć, this setting is available to change the feed water temperature,
it is adjustable by operator: heat curve is not change (the slope is no change), but the point near 5ć
(from 0ć to 10ć), curve can be change step by step; the variable is the biggest at 5ć,itis f3ć
.
When outdoor ambient temperature is 0ć,this setting is available to change he feed water temperature,
it is adjustable by operator: heat curve is not change ( the slope is not change), but the point near 0ć
(from -5ć to +5ć), curve can be change step by step; the variable is the biggest at 0ć,it is f3ć.
When outdoor ambient temperature is -5ć,this setting is available to change he feed water temperature,
it is adjustable by operator: heat curve is not change ( the slope is not change), but the point near -5ć
(from 0ć to -10ć), curve can be change step by step; the variable is the biggest at 0ć,it is ±3ć.

6. Raise or lower the value, using respectively the ”up” or ”down” button. To return to the main menu,
press the left- hand button three times.
Adjustment of the MIN and MAX value
The MIN and MAX value is the lowest respectively highest value that is allowed for the supply line
temperature. Adjusting the minimum and maximum supply line temperature is particularly important if
your home has floor heating. If your house has floor heating and parquet floor, the supply line
temperature should not be higher than 45°C. Else the floor might get damaged. If you have floor coils
and stone tiles, the MIN value should be 22-25°C in summer when no heating is required to obtain a
comfortable floor temperature.
MIN
MIN is the minimum setting of feed water temperature; it is adjustable by operator from10 to 30 ć,
factory setting is 22ć; if the room’s floor use ceramic tile, then the setting of MIN can not less than
22ć (this value can get a comfortable floor temperature); the heat pump will restart as soon as
actual feed water temperature less than MIN setting.
MAX
MAX is the maximum setting of feed water temperature, it is adjustable by operator from 30 to 70ć,
and factory setting is 70ć; if heat pump is using for floor heating, this setting is very important,
because at the time the feed water temperature can not higher than 70ć, otherwise could be
dangerous; the heat pump will stop as soon as actual feed water temperature more than MAX
setting.

ecommend that you call
your installation contractor.

3.5.4 Checking the Safety V
alves
Both safety valves of the heating system should be checked at least four times a
year
to prevent lime deposits
to
clog the mechanism. To
find out where
the safety
valves are
located.
The safety valve of the water heater protects the closed heater against positive pressure. It is
fitted on the cold
water inlet line, its outlet opening facing down- war
ds. If the safety valve is not checked r
egularly,
the water heater
might be
damaged. It is quite normal that the safety valve lets out small amounts of water
when the water heater is
being char
ged, especially if a lot of warm water was used previously.
To
check the safety valves, give the cap a quar
ter of a turn clockwise until the
valve lets out some water thr
ough
the overflow pipe.
If a safety valve does not work pr
operly, it
must be r
eplaced. Check with your
installation contractor.
See ”Refer
ences” on page 28.
The opening pr
essure of
the safety valve is not adjustable.
3.5.5 In the Event of Leakage
In the event of leakage in the warm water lines between unit and water taps, the
shut-off
valve on the cold water
inlet line should be closed immediately.
Call your installation contractor (see ”Refer
ences” on page 28). In the event of
leakage in the sytem
cir
cuit, turn
off
the heat pump and call your
installation contractor immediately.
See ”Refer
ences” on page 28.

4.1 Alarm Messages
In the event of an alarm message, try
to re-start
the unit with the safety switch.
If this does not work, try
to
solve the pr
oblem with the help of the table below. Call your installation contractor if
you need help. See ”Refer
