Product Description
AEROTOP T
High Degree of Efficiency and
Optimized Defrosting
Thanks to the correspondingly
dimensioned air heat exchanger as well
as the unique defrosting system, the
AEROTOP T heat pump is especially
efficient and a cost-saver.
This heat pump always exceeds the
required degree of efficiency
(coefficient) of3.0 (COP at A2W35).
Frost forms on the air exchanger, the
evaporator, if the exterior temperature
is less than 5°C. This results in ice
formation and as a consequence
reduces the heat exchange and with
that the efficiency of the heat pump.
The evaporator must be defrosted to
remove this frost or ice. However, the
defrosting process, carried out by the
AEROTOP T by reversing the cooling
circuit, is cumbersome since the heat
pump does not yield any energy during
the defrosting process but still uses
electricity. This is frequently
unnecessary since frost formation
depends on the humidity in the air.
Instead of the unnecessary defrosting
at timed intervals, the AEROTOP T
determines the correct time to defrost
the unit using a progressive and well
thought out logic with different performance parameters in the cooling
circuit. Thanks to this procedure, the
unit rarely requires any defrosting
during the winter, if any at all, which is
a great advantage.
Cooling with AEROTOP TR
The purpose of heat pumps is primarily
to supply a building with heat. However,
the technology can also be used to
cool a building in the summer.
This involves actively generating the
cooling energy through a process
reversal of the heat pump. In case of
distributor systems specifically
designed for cooling (fan coil or
similar), the cooling capacity of the
heat pump can be transferred optimally
to the building. Cooling ceilings also
have a good cooling capacity and
comfort level. Floor heaters, however,
are only partially suited and provide a
limited cooling effect. Radiator heaters
are unsuitable.
Cascade
Thanks to the new heat pump controller
LOGON B WP61, it is possible to link
and operate several heat generators of
a system in a cascade arrangement.
Cascades with up to 4 heat pumps, or
a bivalent operation in combination with
fossil heat generators are feasible.
When using a cascade formation, the
heat generators switch on or off
depending on the current energy
demand: If the currently running heat
pump cannot satisfy the energy
demand within a specific time, an
additional heat pump/heat generator
switches on.
Quiet Operation
Regardless whether installed indoors
or outdoors, the air-water heat pump
AEROTOP T is characterized by
comparatively very low noise
emissions. This is possible thanks to
the high-performance fan, the very
advantageous air routing, the
noise--dampening insulation of the
cladding, as well as the
multi-dampened support of the cooling
circuit. Additional noise insulation
elements are available for most
variants to reduce sound emissions
further. AEROTOP T heat pumps are
quiet and efficient. However, incorrectly
integrating constructional components
may result in undesired noise increases
if the conditions are unfavorable.
Flexible and Space-Saving
Thanks to the clever utilization of the
geometric properties of the radial fan,
AEROTOP T heat pumps are among
the most flexible, space saving
air--water heat pumps. Especially
noteworthy is the fact that the heat
pump can be placed into the left or right
corner of the utility room when not
using the air ducts. The exhaust
opening is easily moved on-site from
the left to the right and even to the top
without having to use any additional
tools. The intake openi
selected as desired without special
accessories. AEROTOP T heat pumps
are also suitable for outdoors
installation when using the
corresponding accessories.

Product Description
AEROTOP T
Enclosure and Special Components
The enclosure consists of a frame that
is completely free of thermal bridging,
sound dampened, and specifically
developed for use with heat pumps.
The cladding and panels feature a
high-grade insulation to sound-dampen
and thermally insulate the unit.
A pedestal or base is not required since
the feet of the unit feature a vibrationdampening design. All panels can
be detached for easy access to the
internal elements of the unit and for
control or configuration tasks.
The high-performance radial fan
ensures the unit runs efficiently and
quietly. The high performance cooling
circuit is mounted on a vibrationdampened support and features a
thermostatic expansion valve, filter
dryer, inspection glass, high-pressure
pressure controller with manual reset,
and a low-pressure pressure controller
with automatic reset function. The
hermetic scroll compressor is mounted
on a double vibration dampened s
upport. The evaporator consists of a
large-area finned tube heat exchanger
made from aluminum and copper; the
condenser consists of a welded
chromium steel high performance plate
heat exchanger. The environmentally
friendly refrigerant R407C is used as
the working medium. A flow monitor on
the consumer side ensures trouble-free
cooling for reversible heat pumps.

Heat Demand and Heat Capacity
The correct dimensioning of the
air-water pump is a key task. The heat
pump must meet the heat demand of
the building. This demand increases as
the exterior temperature drops but the
heat capacity of the air-water heat
pump decreases at the same time. The
two charts illustrate this opposing trend.

Correct Dimensioning and
Bivalence Point
This makes it clear that a monovalent
system with an air-water heat pump as
the only heat generator has a clearly
overdimensioned heat pump during
most of the year and especially during
the intermediate season. Not only does
this result in higher investments costs,
the more frequent switching (on, off) of
the heat pump also has a negative
effect on the pump's efficiency and
thereby increases operating costs
(see chart A).
A somewhat smaller heat pump is
selected for a bivalent system. This
pump is dimensioned not for the
exterior design temperature of the
system but a slightly higher exterior
temperature instead, the so-called
bivalence point. If the exterior temperature drops below the bivalence point,
an electrical auxiliary heater is
switched on, this then covers the
missing heat output. The heat pump
continues to have priority and, together
with the additionally activated
electrical heater, delivers the required
heat (see chart B).
With a bivalence point, the heat pump
is dimensioned exactly to meet the heat
demand of the building. With lower
exterior temperatures, the electrical
auxiliary heater is activated; with higher
exterior temperatures, the heat pump is
still overdimensioned but to a lesser
degree. An optimal annual degree of
efficiency (coefficient) is achieved if the
bivalence point is set to be slightly
below the temperature most frequently
occurring at the building location.

Operating Limits
General Information
The rated throughput values for
evaporator and condenser are
minimum values. Set points and
adjusted parameters may not fall below
these values to ensure the indicated
performance.
Pipes, tubes, and air ducts must be
kept as short as possible and routed in
such a way that pressure and heat loss
are minimized. Incorrectly or badly
installed or dimensioned pipes, tubes,
or air ducts may damage the heat
pump.
Area of Application
The following chart depicts the
application area of the air-water heat
pump AEROTOP T. Please consult the
performance overview for more
detailed operating specifications for
various heat pump models. The
temperature difference at the
condenser must be between
7 and 10°C.
flow temperature [°C]
Operating the heat pump is prohibited
if the following conditions exist:
• Construction drying
• System/unit used in unfinished
buildings
• Windows or exterior doors
unfinished and locked
These cases require the use of a
specific construction heating system.
Functional heating or surface-ready
heating with the heat pump acc. to
DIN EN 1264 is only permitted when
complying with these conditions.
source inlet temperature [°C]
Furthermore, it must be noted that the
design of the heat pump concerning its
standard operation may not yield the
full extent of the required heat output.
The following notes must be observed
as well:
• Comply with the corresponding
standards and rules of the
floor/screed manufacturer!
• Proper function is only ensured
with a correctly installed system
(hydraulics, electrical, settings)!
• Deviations may damage the
floor/screed!

Planning Notes
Cooling with Heat Pump Systems
Active Cooling
The cooling energy is produced actively
using the heat pump to cool. The
purpose of heat pumps is primarily to
supply a building with heat. However,
the technology can also be used to
cool a building in the summer.
This requires a process reversal during
the cooling cycle. In this case, the heat
emission side (condenser) becomes
the heat absorption side (evaporator).
During this phase, the heat pump
functions like a refrigerator.
The cooling and heating cycle cannot
run at the same time. The use of a cool
store is recommended in any case
to prevent the heat pump from
switching on and off and switching to
water heating too often. Depending
on the system concept, the heating
storage can also be used as cooling
storage. In case of distributor systems
specifically designed for cooling (fan
coil orsimilar), the cooling capacity of
the heat pump can be transferred
optimally to the building. Cooling
ceilings also have a good cooling
capacity and comfort level. Floor
heaters, however, are only partially
suited and provide a limited cooling
effect. Radiator heaters are unsuitable.
Active Cooling Insulation
Water at a temperature less than 17°C
is considered to be cold water. In the
presence of cold water, the usual
heating system insulations cannot be
used. Suitable insulation, especially
when using active cooling, is
necessary. Insulation suitable for cold
water is primarily used to avoid
condensation but also to prevent cold
water absorbing any of the heat, and
also to protect against external
mechanical stresses. Condensation
must be avoided with a suitable
insulation to prevent surface corrosions
on the distributor system or mold in
moist layers.
Insulation for cold water must be
vapor-- proof and installed to all
distributor system elements (pipes,
tanks, pumps, cocks, valves, etc.) in a
vapor-proof manner. Special insulating
materials are commercially available in
different designs (e.g. Armaflex,
Tubolit). Standards SIA 380, DIN 4140
describe the insulation techniques.
Please comply with the guidelines of
relevant local professional associations
(VSI, VDI, FESI).
General Cooling Information
1. The cooling cycle always must be
monitored. If the room air is cooled
unchecked, condensation water will
emerge.
This may damage the equipment
or building components. The flow
temperature in conjunction with the
humidity (dew point contact
temperature detector or room
sensor for humidity and tempera
ture) is best for monitoring.
2. A separate cooling circuit should
be planned for the cooling mode.
This circuit can be combined with a
cooling ceiling or ventilation system,
for example. Partial cooling via the
floor heater or convectors is also
possible if the need for cooling is
limited.
3. Water flow must be ensured or
cooling is not possible. When
cooling via the heating surfaces,
thermostatic individual controls
must be used that can be switched
to cooling mode. The valves are
otherwise closed in summer and
cooling is impossible.
Measures to Reduce the Building
Cooling Capacity
The room cooling capacity is calculated
based on the sum of the individual room
demand. If the cooling demand exceeds
the available cooling capacity, the
following reduction measures may be
used:
1. Direct sunlight through the window
areas can be restricted through
constructional measures (shutters,
window shades, blinds).
2. The amount of sunlight received by
each room frequently differs due to
the different cardinal points.
is means that not the entire
Th
cooling capacity must be available
at the same time. This can reduce
the max. simultaneous cooling
demand.
3. Nighttime cooling of constructional
elements can also lower the
daytime cooling demand.
Calculating the Cooling Capacity
The cooling demand is calculated in
accordance with national and local
standards.
E.G.:
VDI 2078 : Real estate and buildings
DIN 18599: Energetic assessment of
nonresidential buildings (also includes
air-conditioning or cooling)
DIN EN ISO 13790 Energetic
assessment of buildings (similar to
DIN 18599) only across Europe
DIN EN 255
SIA382/2: Room temperature
requirements.
SIA382/3: Determining the cooling
requirement of building.
Cooling is differentiated by internal
cooling capacity (e.g. thermal discharge
of equipment, persons, lights) and
external cooling capacity (sun exposure,
heat from building components, and
ventilation gains due to exterior air).
The estimate acc. to HEA can be used
for approximate calculations. However,
the conditions listed below must
be taken into account as well. The
calculations of the implementation
phase must be based on national
and local standards.

Planning Notes
Cooling with Heat Pump Systems
Comfortable Room Temperature
A room is considered to be thermally
comfortable when the room temperature in the summer is below 28°C.
This does not apply to air-conditioned
rooms. Other factors are affecting
thermal comfort ranges as well.
Thermal comfort requirements are
defined in standard DIN EN 15251,
which provides a general guideline
when implementing construction
projects.
Recommendations for Surface
Temperatures of Cooled Floors
When using a floor area for cooling, the
comfort requirements and the weather
data can be used to estimate the
condensation risk so that the surface
temperatures should generally be in a
range of 20°C to 29°C.
Special attention must be paid to floor
surfaces that are used when barefoot,
for example, in bathrooms, since the
surface temperatures perceived as
being comfortable may be significantly
higher depending on the floor covering.
Rooms with high humidity loads,
especially bathrooms and kitchens,
should not be cooled or only by
considering the dew point threshold.

Cooling with Heat Pump Systems
Monitoring Function to Prevent
Condensate Precipitation
To avoid condensation, the integrated
Logon B WP61 controller features
different monitor functions.
1. Flow Temperature Monitor
The temperature is set at the factory to
18°C. This temperature value ensures
in almost all cases that condensation
does not occur. A dew point monitor
should always be used in addition.
2. Dew Point Monitor
This device is attached to critical points
such as the floor heating distribution
box. As soon as the connected dew
point monitor detects condensation, it
closes the contact and thereby
switches cooling off.
3. Hygrostat
To prevent condensate due to a room
humidity that is too high, a hygrostat
can be connected, which then realizes
a fixed flow temperature increase.
As soon as the value set at the
hygrostat is exceeded, the hygrostat
closes the contact and this triggers the
flow temperature set point increase
set here.
High-End Solutions
4. Humidistat
To prevent condensate due to a room
humidity that is too high, a humidistat
can be connected, which then realizes
a continuous flow set point increase.
If the relative room humidity exceeds
an adjustable value, the flow set point
is increased steadily.
5. Room Sensor for Humidity and
Temperature
The dew point temperature is
determined based on the relative room
humidity and the associated room air
temperature.
To prevent water condensation on
surfaces, the flow temperature is min.
limited by an adjustable value that is
above the dew point temperature.

Compact Heat Pump
Water Heat Exchanger Pressure Loss
The thermal mixing valve integrated
into the compact heat pump routes a
part of the flow water back to the
accumulation tank at flow temperatures
below +30°C. This way the storage
tank is heated immediately and the
energy depot is available for the
defrosting of the evaporator. This
upholding function ensures a
continuous defrosting process and the
system can be operated even when
the heating system is cold.

Reduction table for sound:
This table can be used to estimate the noise level at the measuring location on
the basis of the noise level at the emission location (noise level according to
page 16 and 17). Depending on the legal requirements, further correction factors
have to be considered. In cases of doubt, the emission values should be
calculated by an acoustic specialist.

Checklist
Correct Installation of an Air-Water Heat Pump
AEROTOP T heat pumps are quiet
and efficient. However, incorrectly
integrating constructional components
may result in undesired noise increases
if the conditions are unfavorable.
A careful assessment of the noise
emissions is required when planning
the installation of heat pump systems.
To be considered when installing an air-water heat pump
Each reflecting surface doubles
the noise (acoustic power).
One wall increases this value by
+3dB, one corner by +6dB.
Rooms with reverberant or
sound-reflecting floor coverings
and walls increase the noise
level.
Be careful with dropping the
washing
Adherence with the min.
clearances reduces noise
reflection and air short-circuits
and improves airflow near the fan.
Construction measures can
reduce noise, plants cannot.
Noise reduction measures considered
early on in the development process
result in the fewest additional costs.
Subsequent measures usually are
extremely expensive and cumbersome
to implement. [Heat Pump Manual,
Federal Energy Agency, Switzerland]
The following points apply to the
interior and exterior installation of
air-water heat pumps.
one corner by +6dB.
Avoid solid-borne noise transmission by avoiding reflecting surfaces. Never route air
intake or outlet into closed or partially closed spaces such as a corner, foyer, entrance
area, covered patio, etc.
Avoid rooms with reverberant or sound-reflecting floor coverings and walls. When
installing the heat pump in a room with reverberant or sound-reflecting floor coverings
and walls, reflections may increase the sound level. Cover one or two walls with
noise-absorbing material if this is the case.
Dropping the washing from lived-in rooms to the place of installation of the heat pump
can lead to noise transmission when unfavourably positioned.
Make sure the min. distances and clearances to the air intake and outlet as well as the
min. size of the light wells are applied. Avoid walls or flow barriers around the
circumference of the heat pump to ensure air can reach the fan evenly.
Less pressure losses = low peripheral speed = reduction of the fan noise.
Use constructional measures to interrupt the flow of noise from the heat pump
(direct noise propagation). Use solid walls, fences, palisades, etc. to reduce noise
levels. Plants, however, do not reduce noise.
Consider different noise
sensitivity levels.
Sound absorbing materials
reduce noise.
Separation from the structure
minimizes structure-borne
sounds.
Correct installation of pedestal
or base reduces structure-borne
sounds.
Correct installation of the ducts
reduces air and structure-borne
noise transference.
Avoid air short-circuits and airflow
barriers.
Always comply with all rules,
regulations, and applicable laws.
Avoid placing the heat pump where it may cause problems due to its noise emission
(bedrooms, living rooms, neighbors, etc.). Position heat pumps in areas where noise is
less likely to be an annoyance. If installed indoors, do not install underneath or next to
living or sleeping quarters.
Additional sound absorbing materials or measures must be planned for and used in
cases where extreme noise reductions are desired or when installing model Forever
GREEN 20C or later. Use only original accessories and spare parts. in extreme cases,
it may be advisable to consult a noise expert.
Always use flexible connections throughout: Flexible hoses and tubes for heat
distribution, flexible electrical connections, sound isolation of the air ducts by using
elastic sleeves or Compriband products.
The base or ground must be level or made level and able to support the load of the
equipment. Use the adjustable feet of the heat pump to level the equipment after
installation.
All wall openings and ducts must be equipped with the corresponding noise-absorbing
materials. Comply with the specified cross-sections and dimensions.
Air intakes and outlets cannot be installed next to each other without using a
separating wall. Avoid any airflow obstacles that favor an air short-circuit.
