2 Product description
Heat pump AW OR is included with the unit Compress 5800i 12 E in a
series of heating pumps that extract energy from the outdoor air to
provide water-borne heat and hot water. By turning the process over and
taking up heat from the water and placing it in the outdoor air, the plant
can produce cooling if necessary. However, this requires that the heating
system is intended for cooling operation.
The heating system is controlled by a control unit located in the inside
unit. The control unit controls and monitors the system with the help of
various settings for heating, cooling, hot water and other operations. The
monitoring function closes e.g. of the outdoor unit in case of any
malfunctions so that no vital parts are damaged.
2.1 Protection zone
The product contains the refrigerant R290 that has a density greater
than air. If a leak occurs, the refrigerant could accumulate near the
ground. The refrigerant must therefore be prevented from collecting in
niches, drains, gaps, other sinks, hollows or depressions in the building.
No building openings such as light shafts, hatches, valves, open down
pipes, cellar entrances, windows, doors, roof vents and roof drainage
systems, pump shafts, inlets in sewers, waste water shafts, etc. are
permitted within the defined protection zone around the product. The
protection zone must not overlap general areas or adjacent plots.

No sources of ignition such as contactors, lamps or electrical switches
are permitted within the protection zone. The defined protection zones
are also applicable for installations on pitched roofs, with the addition
that no openings to the building and no sources of ignition are allowed
below the product.
No structural changes are allowed in the protection zone that violates the
rules mentioned above for the protection zone.

2.2 Data plate
• AW OR: The data plate is located on the rear side of the heat pump.
• Compress 5800i 12 M: The data plate is located inside of the indoor
unit. For the exact location (the installation instructions of the
appliance).
The data plate contains information on output, item number, serial
number and date of manufacture.
2.3 Heat pump (outdoor unit)
The heat pump is inverter operated, which means that it will
automatically change the compressor speed to deliver the exact amount
of energy required at the moment. The fan is also RPM controlled and will
change its speed as needed. This provides the lowest possible energy
consumption.
The speed changes have an effect on the sound emissions, as higher
speed results in higher sound emission.
Defrosting
Ice might form on the evaporator during lower outside temperatures. In
case there is enough ice to inhibit the air flow through the evaporator, an
automatic defrosting will start. As soon as the ice is gone, the heat pump
returns to its normal operation.
If the outside temperature is above +5 °C the defrosting will be
performed alongside continued heat production, however if the
temperature is lower, the defrosting is done by ways of a 4-way valve
turning the heat medium direction in the circuit so that the hot gas from
the compressor melts away the ice. The duration of the defrost cycle
depends on the actual outdoor temperature and the amount of frost on
the evaporator.
2.3.1 Range for heat pump without booster heater
In heating mode the heat pump switches off at approx. – 23 °C or +45 °C
outdoor temperature. The indoor unit or an external heat source then
takes over the heating and domestic hot water production. The heat
pump restarts if the outdoor temperature exceeds roughly – 17 °C or
falls below +42 °C.
In cooling mode, the heat pump switches off at roughly +45 °C and
restarts at roughly +42 °C.

2.4 Indoor unit
The task of the indoor unit is to distribute the heat from the heat pump to
the heating system and the hot water cylinder. The circulation pump in
the indoor unit module is RPM controlled, and will automatically
decrease in speed when demand is low. This decreases energy
consumption. When the heating demand is higher during cold outdoor
temperatures, an additional heat source - a booster - may be required.
This booster heater is integrated, an its on/off is controlled by the user
interface in the indoor unit. Please note that when the heat pump is
running, the booster heater will only provide the heating output that the
heat pump cannot produce itself. When the heat pump is able to provide
all the heating needed, the booster is automatically turned off.
Compress 5800i 12 E
When heat pump AW OR is connected to indoor unit Compress 5800i 12
E, an external domestic hot water cylinder is required if the purpose of
the heat pump is also to produce domestic hot water (DHW). In this case,
switching between heating and DHW is managed by an internal 3-way
valve. The integrated booster in the indoor unit will turn on if needed.

2.5 Hints on energy saving
• Use the normal heating mode, thus the heating system will use the
least energy. Set the desired room temperature according to your
personal comfort needs.
• Open the thermostatic vents fully in all rooms. Increase the
temperature setting on the control only when the desired room
temperature has not been reached for some time. Close the
thermostatic valve in a specific room, only if that room is warmer then
the others.
• If there is a room controller installed, this can be used to set the
optimal room temperature. Avoid influence of external heating (i.e
sunlight or wood stove). Otherwise unwanted fluctuations in the
room temperature may occur.
• Avoid placing big objects e.g. a sofa in front of the radiators
(minimum 50 cm distance). This will block the circulation of the
heated air in the room.
• Do not set a too low temperature for cooling. Cooling will also
consume energy.
Vent the room correctly
Open the windows fully for a short period instead of leaving them ajar.
Leaving the windows ajar will let the heated air out of the room constantly
without increasing the air quality. Close the thermostatic valves or lower
the heating setting on the room controller while the room is vented.
2.6 Control unit
If a room controller is installed, the thermostatic valves in the reference
room (the room in which the remote control is installed) must be fully
open!
Depending on the software version of the user interface, the texts shown
in the display may differ from the texts in these instructions.
The adjustment ranges, default settings and functional scope may differ
from the information in these instructions, depending on the system
installed at the site.
• If special system components and modules are installed,
corresponding settings are available and necessary.

5.1.1 Check system pressure
▶ Check the pressure on the pressure gauge. The pressure is also
shown in the system overview on the display (Chapter 2.6.1).
▶ If the pressure is lower than 0.6 bar, slowly increase the pressure in
the heating system by adding water through the filling valve to a
maximum of 2 bar.
▶ Contact your installer or reseller if you are insecure how to perform
the filling.
5.1.2 Particle filter
WARNING
Strong magnet!
Can be harmful to pacemaker wearers.
▶ Do not clean the filter or check the magnetite indicator if you are a
pacemaker wearer.
The filter prevents particles and contamination from entering the heat
pump. Over time, the filter may become blocked and must be cleaned.
The system does not need to be emptied to clean the filter. The filter is
integrated into the shut-off valve.
Cleaning the strainer
▶ Close the valve (1).
▶ Unscrew the cap (manually) (2).
▶ Take out the strainer and clean it with running water over it or by
pressure cleaning.
▶ Check attached debris on the cap’s magnet (3) and clean it.
▶ Reinstall the strainer (4). For proper assembly, make sure that the
guide bumps fit into the recesses in the valve.
▶ Screw the cap back on (hand tight).
▶ Open the valve (5).
Fig. 14 Cleaning the strainer
Check and clean the magnetite filter

exceeded. Contact the installer if water is coming from the safety
valves below the maximum allowed pressure.
5.2 Heat pump (outdoor unit)
The following inspection and maintenance steps are carried out several
times per year in order that the heat pump's maximum output will be
maintained:
▶ Housing (casing)
▶ Cleaning of the evaporator
▶ Snow and ice
5.2.1 Housing (casing)
Dust and other dirt particles concentrate in the heat pump's outdoor unit
over time.
▶ Remove dirt and leaves from the heat pump with a brush.
▶ If required, clean the outside with a damp cloth.
▶ Spot repair cracks and damage on the casing with anti-corrosive
paint.
▶ Standard car wax can be applied to protect the paint.
5.2.2 Evaporator
Any layers of dust or dirt, for example, deposited on the surface of the
evaporator must be removed.
CAUTION
The aluminium fins are thin and sensitive.
They can be damaged easily due to careless handling.
▶ Never use hard objects.
▶ Never rub the fins directly with a cloth.
▶ Wear protective gloves.
▶ Never use water pressure that is too high.
Damage to system due to use of unsuitable cleaning agents!
▶ Do not use acidic or alkaline cleaning agents or cleaning agents
containing chlorine or abrasive products.
▶ Do not use strong alkaline cleaning agents, e.g. sodium hydroxide.
Cleaning of the evaporator:
▶ Spray a cleaning agent on the evaporator fins on the back of the heat
pump.
▶ Rinse off coatings and detergent with water.
In some regions, the cleaning agent must not be flushed into gravel beds.
If the condensate tube discharges into a gravel bed:
▶ Remove the flexible condensate tube from the drain pipe prior to
cleaning.

can get stuck on the back and the roof of the heat pump. Make sure to
clear the snow to prevent icing-up.
▶ Carefully brush the snow off the fins.
▶ Clear the snow off the roof.
▶ Hot water can be used to rinse off the ice.
Moisture can form under the heat pump due to condensate not falling
into the condensation catch pan. This is normal and no special action is
required.
5.3 Faults
Faults can be of different kind and severity, indicated by the colour of the
fault icon and the text associated with it. If present, the four digit number

9 Display of consumption values in relation to the
funding guidelines for federal funding for
efficient buildings - individual measures (BEG
EM)
The displayed energy consumption, heat quantities and device
efficiency (hereinafter "consumption values") are calculated from
device-specific data and measured values. The consumption values
displayed are only an estimate (interpolation).
In real operation, many different factors influence energy consumption.
The specific consumption values are among others influenced by:
• Installation / execution of the heating system,
• user behaviour,
• seasonal environmental conditions,
• components used.
The consumption values displayed relate exclusively to the heating
appliance. Consumption values of other components of the entire
heating system (complete heating system with all its associated
components), such as i.e. external heating circulation pumps or valves
are not taken into account. The deviations between the displayed and the
actual consumption values can therefore be considerable in real
operation.
The representation of the consumption values enables the operator to
make a relative comparison of the energy consumption over time. In
addition, excess or reduced consumption can also be determined. A use
for binding billing purposes is not possible.
10 Technical terms
Heat pump (outdoor unit)
The central heat source. Installed in the open air. Alternative
designation: outdoor unit. Contains the cooling circuit. Heated or cooled
water is channeled from the outdoor unit to the heat pump module
(indoor unit).
Indoor unit
Installed in the building and distributes the heat from the outdoor unit to
the heating system or the DHW cylinder. Contains the control unit and
the pump in the heat transfer medium line for the outdoor unit.
Heating installation
Designation for the entire installation, comprising the heat pump, heat
pump module, DHW cylinder, heating system and accessories.
Heating system
Comprises the heat source, container, radiators, underfloor heating
system or fan convectors or a combination of these elements if the
heating system is made up of several heating circuits.
Heat. circ.
The part of the heating system that distributes the heat throughout the
various rooms. Consists of pipework, pump and radiators, heating hoses
of the underfloor heating system or fan convectors. Only one of the
specified alternatives is possible within a circuit. However, if for example
the heating system is equipped with two circuits, radiators can be
installed in one and an underfloor heating system installed in the other.
Heating circuits can be configured with and without mixers.
Heating water/domestic hot water
If domestic hot water is connected to the system, a distinction is made
between heating water and domestic hot water. The heating water is
channeled to the radiators and the underfloor heating system. Shower
and water taps are supplied with domestic hot water.
If a DHW cylinder is present in the system, the control unit switches
between heating and DHW mode so that maximum comfort is achieved.
The DHW or heating mode can be prioritised by selecting an option on
the control unit.
Heating circuit without mixer
In a heating circuit without mixer the temperature in the circuit is
controlled purely by the energy from the heat source.
Heating circuit with mixer
In a heating circuit with mixer, the mixer mixes return water from the
circuit with water from the heat pump. This allows heating circuits with
mixer to be operated at a lower temperature than the other heating
system, e.g. so that underfloor heating systems that operate at lower
temperatures can be separated from radiators that require higher
temperatures.
Mixer
The mixer is a valve that steadily mixes colder return water with hot water
from the heat source in order to achieve a specific temperature. The
mixer can be situated in a heating circuit or in the heat pump module for
the external auxiliary heater.
3-way valve
The 3-way valve distributes thermal energy to the heating circuits or the
DHW cylinder. It has two defined settings so that heating and DHW
heating cannot occur at the same time. This is also the most effective
operating mode, as the DHW is always heated to a specific temperature,
while the heating water temperature is continuously adjusted to the
outdoor air temperature in each case.
External auxiliary heater (extra)
The external auxiliary heater is a separate heat source which is
connected via pipework to the indoor unit. The heat produced in the
auxiliary heater is controlled via a mixer. It is therefore also referred to as
an auxiliary heater with mixer. The control unit controls the activation
and deactivation of the auxiliary heater according to the existing heat
energy demand. Heat sources are electric, oil-fired or floor standing gas
boilers.

Heat transfer medium circuit
The part of the heating system that transports the heat from the outdoor
unit to the indoor unit.
Cooling circuit
The main part of the outdoor unit that obtains energy from the outdoor
air and transfers this as heat to the heat transfer medium circuit.
Consists of evaporator, compressor, condenser and expansion valve.
The refrigerant circulates in the cooling circuit.
Evaporator
Heat exchanger between air and refrigerant. The energy from the air that
is drawn in through the evaporator causes the refrigerant to boil and turn
to gas as a result.
Compressor
Moves the refrigerant through the cooling circuit from the evaporator to
the condenser. Increases the pressure of the gaseous refrigerant. The
temperature also increases as the pressure increases.
Condenser
Heat exchanger between refrigerant in the cooling circuit and water in
the heat transfer medium circuit. During the heat transfer, the
temperature of the refrigerant falls as it changes into the liquid
aggregation state.
Expansion valve
Reduces the pressure of the refrigerant after it is discharged from the
condenser. The refrigerant is then channeled back to the evaporator
where the process starts again.
Inverter
Located in the outdoor unit and enables the speed of the compressor to
be controlled based on the heat energy demand in each case.
Setback phase
A period during the time-controlled operation involving the setback
operating mode.
Time-controlled operation
The heating system is heated in accordance with the time program and
switching between the operating modes occurs automatically.
Operating phase
The heating operating phases are: heating and setback. They are
depicted by the symbols and .
The operating phases for DHW heating are: Comfort, Eco and Eco+. A
temperature can be set for each operating phase (except for Off).
Frost protection
Depending on the type of frost protection selected, the outdoor unit is
switched on if the outside temperature or room temperature falls below
a certain critical threshold. Frost protection prevents the heating system
from freezing up.
Desired room temperature
The room temperature to be achieved by the heating system. It can be set
individually.
Default settings
Values saved permanently on the control unit, which are available at all
times and can be reset as necessary.
Heating phase
A period during the time-controlled operation involving the heating
operating mode.
Parental lock
Settings in the standard display and in the menu can only be changed if
the parental lock (key block) is switched off.
Mixer/mixing valve
Assembly that automatically ensures that DHW can be drawn from the
draw-off points at a temperature no higher than the temperature set on
the mixing valve.
Normal Operation
In normal mode, automatic mode (the heating system time program) is
not active and the home is steadily heated at the temperature set for
normal mode.
Reference room
The room in your home where the remote control is installed is the
reference room. The room temperature in this room acts as the control
variable for the assigned heating circuit (which can include several
rooms or the entire house if only one circuit is present).
Switching time
A particular time when the heating temperature, for example, is
increased or reduced. A switching time is a component of a time
program.
Temperature during an operating phase
A temperature that is assigned to an operating phase. The temperature
is adjustable. Refer to the explanations about the operating mode.
Flow temperature
The temperature that the heating water in the heating circuit retains from
the heat source through to the radiators or the underfloor heating system
in the room.
Hot water cylinder
A DHW cylinder stores large volumes of heated potable water. Sufficient
hot water is available at the draw-off points (e.g. water taps) as a result.
Time program for heating
This time program ensures automatic switchover between the operating
phases at defined switching times.
