2. INTENDED USE
This unit is designed for use as an exhaust air heat pump in multi-storey residential buildings. It may only be
operated in exhaustair systems with normal air (low dust content) up to 40°C conveying medium temperature.
For proper and efficient use, the unit requires a minimum exhaust air volume that is always present (see the
Technical data/minimum exhaust air volume flow section).
On the heating side, the lowest possible system temperatures are an advantage. If the operated heat sink is
not extremely large, a stratified storage tank must be connected to the device to ensure efficient operation
and long heat-pump running times. We recommend a capacity of 300 litres and use in conjunction with a low-
temperature heating system. The unit can only provide heat input if a sufficiently large heat sink is available.
The unit’s operating limits must be taken into account here. It is not possible or permitted to preparedomestic
hot water using this unit alone. The applicable regulations for domestic hot water hygiene must always be
observed.
The unit is approved exclusively for outdoor installation on the flat roof of a building with a maximum
building height of 60 m (Eco+ 111/ Eco+ 121) & 50m for Eco+ 131. Installation in zones other than
wind zones 1-3 (DIN EN 1991-1-4:2005) is not permitted.
The procedures described in these assembly instructions for assembly, operation and maintenance must
also be observed when using the unit for its intended purpose. Please read all the assembly instructions
before starting work. Modifications and alterations are only permitted with our written approval.
The unit warranty shall not cover the cost of motor ladders, scaffolding or other lifting systems which may be
necessary to provide the services covered by the warranty. The unit must be installed by trained personnel
in compliance with the national legislation in force in the country of destination.
The unit must be installed in such a way that maintenance and/or repair work can be carried out. The warranty
shall become void if work is carried out on the unit contrary to the instructions given here or in any other way
without professional care.
Approved refrigerants
It is forbidden to fill the refrigerant circuits with a refrigerant other than the one specified.
Using another refrigerant can seriously damage the compressor.
System logbook
We recommend that you keep a system logbook, which can be used to trace the operations carried out on
the unit. In this way, interventions can be organised more easily, searches can be made easier and machine
defects can be avoided. The date, type of intervention carried out (regular maintenance, inspection or repair),
description of the intervention, measures taken, etc., should be entered in the system logbook.
Disposal
The unit must be disposed of in accordance with the regulations in force in the individual countries.

TF7039GB_A_NOT

3. SAFETY REGULATIONS
The unit is not a complete machine and is therefore not a ready-to-use product. It may only be operated if it
is connected to an air conditioning system and a permissible heat sink in accordance with these instructions.
Assembly, electrical installation and repair may only be carried out by trained specialist personnel. Only op-
erate the device in the areas indicated on the type plate or in the technical data.
Only use the device for its intended purpose. Planners, system constructors or operators are responsible for
proper and safe installation and operation. Safety components, e.g. protective grids, must not be bypassed
or rendered inoperative.
Before starting any work, read this manual carefully and undertake any necessary safety checks
to prevent any risk.
All persons carrying out work on the device must be physically, healthily and professionally apt,
and must be equipped with suitable personal protective equipment (PPE). Adequately ensure it
is not possible to fall off the building.
The unit is largely made of sheet metal and has sharp-edged components due to the production
process. These do not represent a hindrance or risk of injury when used as intended. During
assembly, however, contact with these components can lead to injuries. Therefore, fitters should
always wear protective gloves when working on the unit.
Only open the unit when it is switched off. During operation, and when the fan is running on, there
is negative pressure in the housing.
The device generates heat. Parts of the unit, especially inside the compressor housing, can be-
come very hot.
When working on the roof, ensure that all parts detached from the unit cannot be blown away or
fall.
This unit contains fluorinated greenhouse gases covered by the Kyoto Protocol. Maintenance and disposal
work may only be carried out by qualified personnel.
With regard to the selection of protective devices (e.g. miniature circuit breakers), cable cross-sections, earth-
ing, measurements to be carried out, etc., DIN VDE, BG, EVU and VDS regulations, as well as the generally
recognised rules of technology must be followed and observed. The planning/exercise or the observance of
these is carried out exclusively by specialist planners/engineering offices/installers.

4. UNIT DESCRIPTION
The AWN Eco+ is an exhaust fan with integrated exhaust air heat pump for outdoor installation. The exhaust
fan is intended for conveying exhaust air from apartments at a constant negative pressure. The AWN Eco+
continuously adjusts its output to the existing exhaust air volume flow.
The unit includes a water-cooled heat pump that operates with R410A refrigerant in a hermetic cooling circuit
with inverter rotary piston compressor. It is a single-circuit unit with hermeticcooling circuit and inverter rotary
piston compressor, as well as a plate heat exchanger on the system side and a lamella heat exchanger on
the source side (direct evaporator). Two automaticvent valves as well as asafety valve(3.0 bar) are installed
on the sink side as standard. Microprocessor-controlled regulation including LCD display allows the heat
pump components to be operated easily via the user menu. The exhaust fan can be regulated via a separate
control unit.
TYPE PLATE
The unit is labelled with a technical type plate.
Do not modify or remove the type plate.
LOAD-BEARING CONSTRUCTION AND ERECTING DEVICE
The construction is based on a hot-dip galvanized steel frame of appropriate thickness. All other parts in
contact with the environment are made of sufficiently corrosion-resistant materials. To lift the unit, eye bolts
must be attached to the top corners of the frame. (These must be removed after installation and the remaining
openings must be closed with the enclosed cover caps.)
During the design phase, it was ensured that all interior components are easily accessible. All inner surfaces
on the exhaust side are lined with sound-absorbing material of suitable thickness.
The unit is equipped with feet which are each fitted with a base plate with two holes for
mounting fasteners. Each foot sits on a 20-mm-thick anti-vibration mat, which also pro-
tects the roof skin from damage and reduces the transmission of structure-borne noise
to the installation surface.

4.5.2. REFRIGERANT CIRCUIT COMPONENTS
COMPRESSOR
A hermetic inverter rotary piston compressor that is highly efficient and uses an energy-saving DC electric
motor. Mounted on elastic vibration-damping compensators.
COMPRESSOR INVERTER MODULE
The inverter module infinitely controls the compressor speed using the sensor-controlled power specification
on the system controller. This means the compressor motor is continually monitored and protected from
damage.
CONDENSER (SINK SIDE)
Plate structure (stainless steel, 1.4401), with closed cell insulation material to reduce heat loss
EVAPORATOR (SOURCE SIDE)
Cooling fin structure (copper/aluminium), surrounds the fan in a circle
REFRIGERANT COLLECTOR

TF7039GB_A_NOT
Page 17 of 48
4.5.3. HEATING WATER CIRCUIT COMPONENTS
SAFETY VALVE (3 BAR)
In the event of pressure faults in the heating water pipes, a safety valve is triggered and excess pressure is
released. This can be connected to a drain on site.
VENTILATION VALVE
Used to manually vent the system.
DRAIN COCK
To drain the system, a drain line is provided at the lowest point of the heating water pipe in the unit for service
and decommissioning purposes.
BUFFER CHARGE PUMP
A hot water feed pump provides an available external feed pressure to overcome pressure losses outside
the heat pump in the heating circuit between the heat pump and the hot water buffer. The feed volume of this
high-efficiency energy-efficiency pump is adjusted by the electronic system control by means of a PWM sig-
nal.
VOLUME FLOW SENSOR AND HEAT METER
A heat meter determines the volume flow of the heating water in the heat pump and its temperature at the
heat pump heating water outlet. An additional temperature sensor is fitted at the heating water inlet. The
respective measurement data is transferred to the unit control system. The quantity of heat discharged is
calculated from the volume flow and the temperature difference.
4.5.4. HEAT PUMP CONTROL AND SAFETY COMPONENTS
LOW-PRESSURE PRESSURE SWITCH
This device fixed on the low-pressure side of the cooling circuit stops the compressor from running if the
normal operating pressure range is undershot.
HIGH-PRESSURE PRESSURE SWITCH
This device fixed on the high-pressure side of the cooling circuit stops the compressor from running if the
normal operating pressure range is overshot.
ELECTRONIC CONTROL AND SWITCH PANEL
The unit is equipped with a switch and control cabinet (IP65), including:
•Terminals for connecting the external temperature sensors
•Terminals for connecting external components such as heating circuit pump or heating circuit mixer
•Terminals for boiler/heating resistor alarm signal input
•Terminals for public authority approval and Smart Grid approval
The heat pump can be switched on and off via the public authority approval. The exhaust fan is in-
tended for continuous operation. A corresponding release line is therefore not provided for the venti-
lation components.

TF7039GB_A_NOT
Page 18 of 48
ELECTRONIC CONTROL (UVR 1611)
The unit control panel allows plant operating parameters to be adjusted quickly and intuitively. The display
shows various indications of the operating mode, set parameters and any alarms triggered. All standard
settings and any changes are saved in the controller control panel.
After a power failure, the unit is able to restart automatically and retains the original settings.
Some accesses are password-protected and are only available for technical customer service.
The electronics also include a range of protection algorithms to prevent damage to key plant components.
For more information on operation and control logic, see the Control manual operating instructions
(UVR).
