Customer Information
These operating instructions are part of the unit and must remain with it. This manual contains important notes and tips on operating your compact unit, which protect you from personal injury and
also guarantee a long service life of the unit. The fi gures all depict the right-hand version of the
device (supply air connection located on the right). All instructions are equally applicable to the
left-hand version (supply air connection located on the left). Please keep the operating instructions for future reference. Please pay attention to the safety instructions!
Product Description
The devices in the aerosmart series are compact units which consist of a ventilation
module with heat recovery, a domestic water storage tank and a heat pump. The unit is
used to heat the supply air and the domestic water. The aerosmart S, aerosmart M und
aerosmart L units are operated via a micro-processor controller. Although the unit types
differ in terms of their appearance, weight and managed air quantities, these differences
do not affect their operation.
Proper Application
The unit is designed for the ventilation, heating and warm water generation of living rooms
and lounges in passive houses and, if applicable, for near-passive buildings depending
on the calculation and building design.
Unsuitable Applications
No applications other than those specifi ed under proper application are permissible.
The unit must not be used to dehumidify buildings under construction. Drying and heating
a building structure can cause considerable damage to the unit. The ventilation of rooms
with extremely high humidity levels, such as saunas, or heavily contaminated extract air
is also not permitted.
Safety Instructions
WARNING: Indicates that the non-adherence to the recommended safety
procedures could lead to damage to the unit or personal injury.
CAUTION: Indicates that the non-adherence to the recommended safety procedures could lead to damage to the unit.
NOTE: Helpful information and useful tips.

Operation
The unit is controlled, managed and operated via a micro-processor controller on the unit and a
room operating panel. Two types of room operating panels are available:
•
Analogue room operating panel with heating mode
Digital room operating panel•
If the analogue room operating panel is used, the basic settings must be made on the compact
unit (micro-processor controller) during commissioning.
If the digital room operating panel is used; the settings can all be made on either the room operating panel or the micro-processor controller.
Micro-Processor Controller
The micro-processor controller is located on the ventilation module. It manages the ventilation, room heating and the heating of the domestic hot water.

Analogue Room Operating Panel with Heating Mode
Use this room operating panel to set the room temperature and activate the special 'Party'
mode. The LED indicator lights show if the heating is activated and if a fi lter change or
fault is pending.
Setting the Room Temperature
The dial can be used to adjust the set-point temperature by +/- 3°C. On delivery of the
system, the middle setting is 21.5°C.
This means that the temperature can be adjusted from 18.5°C (dial fully to the left) to
24.5°C (dial fully to the right).
Note: Do not turn the dial too far! The left stop point is at approx. 8 o'clock, the right-
hand stop point is at approx. 4 o'clock.
What room temperature is right for me?
The setting basically depends on your needs. Temperature sensitivity in humans is subjective and differs from one person to the next. Standard settings are between 20 and
23°C.
Environmental infl uences
As the room operating panel has a temperature gauge to measure the room temperature,
no heat-emitting devices should be placed beneath it or in its immediate vicinity (e.g. televisions or computers).
Such heat-emitting devices would substantially infl uence the temperature measure-
ments.

aerosmart - Operation, Maintenance and Commissioning
A handy hint for greater system effi ciency
If possible, fi nd your desired temperature at the start of the heating period.
The system works most effi ciently if the set-point temperature is set once and then left
unchanged. Regularly changing this setting uses the top up heater in the room more than
necessary.
Special 'Party' Mode
Pressing the 'Party' button sets the ventilation to fan level 3 for a predetermined period.
Once this period has passed, the fan level automatically returns to the currently set level.
On delivery of the system, the default period is 60 minutes, but this can be adjusted on
the micro-processor controller. The special 'Party' mode cannot be reset by pressing the
button again.

Maintenance
System maintenance by users is mainly limited to regularly changing the coarse particle fi lters
in the ventilation module and the fi ne particle air fi lter in the outside air unit. The operating unit
provides regular fi lter change notifi cations as the system operating hours are counted in the
background. A reminder to change the coarse particle fi lters is displayed approx. every 60-180
days, according to the managed nominal air quantity (depending on the environment and the fi lter
class). The fi ne particle air fi lter only has to be changed approx. once or twice a year. As the fl ow
capacity and acoustic level generated by the compact unit are affected by the amount of dirt in the
fi lters, we recommend that fi lters are changed regularly. No tools are required.
Caution: Possible damage to the unit resulting from dust and contamination. The coarse
particle fi lters in the unit not only improve your air quality, but also protect the entire ven-
tilation system. The system must not be operated without a coarse particle fi lter.
Note: The fi lter should be changed within 2-4 weeks of the 'Filter change' message
appearing..
Safety Instructions for Filter Changes
Caution: The fi lter change intervals are only valid for a completely run-in system. After
the initial commissioning, the fi lters can sometimes become very dirty after a relatively
short time (construction dust). In this case, no error message is displayed.
Caution: Filters cannot be washed or vacuum cleaned as this would drastically affect
their functionality . Contaminated fi lters must always be replaced with clean fi lters. Filters
should be disposed of in the residual waste.
Caution: For uninterrupted operation of the ventilation unit, we recommend that the
system is serviced by an authorised service partner after two operating years. Local
laws and regulations governing maintenance intervals and procedures must be adhered to.
Changing Coarse Particle Filters
Do not switch off the device or unplug it from the mains as the controller will not detect the change
of fi lter .

the error message 'Change fi ne particle air fi lter' is displayed, replace the dirty fi ne particle
air fi lter (within 2 - 4 weeks) with a new fi lter of the same type. For some
fi lter types, the ventilation direction must be taken into consideration
(marked by an arrow). The fi lter change must be ac- knowledged

BW-Sollwert
The DW set-point (domestic water set-point) can be set from 37°C to 50°C. If, for example,
the set-point is set at 42.0°C, domestic water heating is enabled as soon as the temperature
in the lower area of the boiler (actual value) falls below this point. On reaching 47.0°C, i.e.
5°C above the set-point, the domestic water heating process is switched off again.
What domestic water temperature is right for me? The usual domestic water temperature is
36-38°C for showering, 37 to 42°C for having a bath and 40 to 45°C for washing dishes. Depending on the temperatures you are used to, we recommend a DW set-point temperature
of between 38 and 48°C.
Page 16
Note: If no warm water is removed for an extended period during the heating period, the do-
mestic water temperature can exceed the predetermined set-point.
Zyklisches Aufheizen
This parameter makes it possible to regularly heat domestic water to 60°C. (immersion heater must be switched on).

Tr Current room temperature measured by the sensor on the control unit or
an external room sensor
Tb Temperature on the heat pump evaporator register
Tu Current temperature in the lower area of the boiler. Depending on this
temperature, the heat pump is activated.
Tm Current temperature in the middle area (centre) of the boiler. Depending
on this temperature, the domestic water heating can be given priority and
the room heating can be temporarily disabled by the heat pump.
Verd. Current status of the compressor or the heat pump
MV-FL Current status of the liquid line's solenoid valve. This valve is only closed
at the start of thawing; it otherwise opens when the compressor operation
starts.
MV-HG Current status of the hot gas line's solenoid valve. It is open during the
compressor's start phase (unloaded start) and during the thaw process.
MV-LU Current status of the air capacitor line's solenoid valve. Air heating is ena-
bled when this valve is open.

Faults
Error Messages
The messages described here are displayed on both the micro-processor controller and
the digital room operating panel. The faults cannot be acknowledged until they have been
resolved. If several faults occur simultaneously, use the up
to scroll through the error messages.
If a fault cannot be acknowledged by holding down the Enter button (2 sec), please contact your customer service technician.
Warning: Electrically conductive components can cause serious personal injury! Improper working procedures could damage unit components. The inner inspection cover
may only be opened by authorised technicians.
Alarm Niederdruck-Pressostat:
Check if the air quantity is too low due to a closed air line. (E.g. very dirty exhaust air fi lter,
contaminants in the air line).
The following operating conditions are not permissible for the heat pump: room temperature
too low; outside air entrance temperature from the ground source heat exchanger too low;
lack of cooling agents
'↑' and down '↓' arrow buttons
Alarm Hochdruck-Pressostat:
Air quantity too low. The heat cannot be dispersed via the air. (E.g. minimum air quantity set
too low, frozen outside air grid in winter)
Zuluftventilator ausgefallen / Abluftventilator ausgefallen
A valve has failed. If the fault cannot be acknowledged by holding down the Enter button
(2 sec), please contact your customer service technician.
Blocktemperatur zu tief
The following operating conditions are not permissible for the heat pump: room temperature
too low; outside air entrance temperature from the ground source heat exchanger too low;
block gauge faulty; extract air fan faulty or dirty.
Low air quantity and very damp extract air
Closed extract or exhaust air line
Fühlerfehler Verdampfer / Boiler unten / Mitte
Temperature gauge/cable faulty / connector loose; all the system's temperature gauges are
monitored. If the lead to a sensor is disconnected, a gauge provides meaningless values
or a short-circuit occurs, a relevant error message is issued and an emergency program is
enabled.
Übertemperatur Boiler Wärmepumpe aus
1. Storage tank temperature above 68°C - unit automatically switches to fan level 3; blocked
supply air fi lter or fi ne particle air fi lter, authorised technicians to check ground source heat
exchanger.
2. Storage tank temperature above 73°C - storage tank overheats, system switches off;
shortly after the initial commissioning (approx. 20 minutes), check if the DW storage tank is
fi lled with water. If necessary, fi ll the DW storage tank with water.
While heating the building envelope; if no warm water has been taken from the DW storage
tank for a long time. Remove warm water.
If the fault reoccurs within a short timeframe, check if the coarse particle fi lter and the fi ne
particle air fi lter have become extremely dirty (possibly through construction dust). If the fault
reoccurs, contact customer service technician.

No Link (or no text in the digital room operating panel)
Fault with addressing the digital room operating panel; the digital room operating panel is
already correctly addressed on delivery. It is, however, possible that the message 'No link'
appears after commissioning or changing the room operating panel. To create a link to the
micro-processor controller, the address must be corrected on the operating panel:
Hold down the '↓', '↑' and '↵' buttons at the same time until the text: '
SETTING' appears.
DISPLAY ADDRESS
b
Confi rm your selection by pressing '↵' (cursor fl ashes on the address)
b
Use the '↓', '↑' arrows to set the correct address (I/O board address 00: display address: 00
or I/O board address 01: display address: 32)
b
Confi rm the new value by pressing '↵'.
The following message appears: 'DISPLAY ADDRESS CHANGED'
b
The room operating panel now has the correct address and operates alongside the microprocessor controller in the ventilation unit.

Noises
The unit is becoming louder by the day since its initial commissioning: exhaust air fi lter / sup-
ply air fi lter very dirty - fans working at an increased speed to try to achieve the minimum air
quantity. Check the condition of all fi lters.
Unit becomes louder during operation: impermissible resistance in an air line (e.g. contaminant blocking air inlets, outside air inlet frozen over in winter)
