Unit Description
In order to get the best results from the climate system AWA-SS series you should read through the
section For the System manager in these Installation and Maintenance instructions.
AWA-SS series
is
a
climate system
for
heating
houses
and
apartment
buildings
as
well
as
industrial
properties.
Air
is
used
as
the
heat
exchange
source.
AWA-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
(supply

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
.
