AEROMAT VT WRG 1000 Operating and Care Instructions
Intended use
• The AEROMAT VT WRG 1000 is intended for installation in the exterior windows/walls of permanent structures in accordan-
ce with our installation and design documents as well as the specifications of our assembly instructions and is only suitable
for the ventilation of enclosed rooms.
• Do not use the AEROMAT VT WRG 1000 in environments with corrosive or explosive atmospheres (dust, vapour or gas).
• If the AEROMAT VT WRG 1000 is to be used in a room with a heating unit that draws air from the room, prior authorisation
must be obtained from the proper authorities, such as the officially appointed district chimney sweep. Intended use requires that
any combustion air lines and exhaust gas systems of solid fuel heating units must be able to be shut off.
• Only operate and/or store the AEROMAT VT WRG 1000 at temperatures between -15 °C and +40 °C.
• Use the AEROMAT VT WRG 1000 only with genuine accessories from SIEGENIA.
• Use the AEROMAT VT WRG 1000 only when it is in a technically sound condition. Do not modify the unit's components in any
way.
• Ventilation openings must be kept free and must not be blocked by other equipment, furniture or objects.
• If the AEROMAT VT WRG 1000 is fitted with filters, you must make sure that these cannot become the source of elements that
are odorous and harmful to health; this also includes regular inspection and replacement of filters.
• In the event of a fault, only have the AEROMAT VT WRG 1000 repaired by experienced specialists with training and practice
in the repair of ventilation units.
Safety notices
• This unit can be used by children aged 8 and above as well as by people with physical, sensory or mental difficulties or with
a lack of experience and knowledge as long as they are supervised or have been instructed in how to use the unit safely and
understand the resulting risks. Children must not play with the unit. Cleaning and user maintenance must not be carried out by
children without supervision.
• Only insert the Euro plug of the network connection cable into a suitable 230-V AC mains power supply.
• If the network connection cable is damaged, it may only be replaced by SIEGENIA, its customer service department or a qua-
lified electrician.
• Work on a 230-V AC mains power supply may only be performed by a qualified electrician.
• All work on the 230-V AC mains power supply must be carried out in compliance with the current German VDE regulations
(e.g. VDE 0100) and any relevant country-specific requirements.
• All-pole safety isolation should be used when fitting the network connection cable on-site.
• Should a solid object or any liquid get inside the unit, stop operation immediately and disconnect the AEROMAT VT WRG
1000 from the mains power supply:
- Check whether the AEROMAT VT WRG 1000 has become damaged.
- Have the unit repaired by a specialist if necessary.

Operating and Care Instructions AEROMAT VT WRG 1000
Function
Ventilation with blowers and heat recovery (schematic diagram)
• The outdoor air (1) is drawn in through the outdoor air filter (2) or insect grille (2, optional) using the supply air blower (3) and
enters the room as supply air (4).
• The exhaust air (5) is drawn in through an exhaust air filter (6) using the exhaust air blower (7) and makes its way outside as
outgoing air (8).
• Both streams of air are drawn through the heat exchanger (9). Here, particularly during cold times of the year, the outdoor air
is pre-heated by the warm exhaust air before it enters the room as supply air.
Ventilation without blowers
• When the blowers are switched off and the locking bolts are open, the unit equalises the pressure of the indoor and outdoor
air to allow fresh air from the outside to flow into the room (pressure differential principle). Because the blowers are not moving,
the air in both air canals flows in the same direction, meaning that air is generally drawn in from the outside into the room –
depending on the weather, the wind pressure increases the air flow into the room. Heat recovery does not take place when
the blowers are not used for ventilation.
Operation in automatic mode (only for units with sensors)
• Depending on the CO2and VOC content as well as the temperature and air humidity, the AEROMAT VT WRG 1000 switches
to blower levels 0, 1 or 2 automatically.
• In automatic mode, the blowers are controlled according to the humidity and temperature inside the room if an indoor sensor
has been installed. The levels are based on comfort criteria.
• If indoor and outdoor sensors are connected, the room is ventilated if the absolute water content of the air outside is lower than
that of the air inside.
• If a CO2/VOC sensor is connected, the blowers switch to the next level depending on the CO2/VOC content.
• If several sensors are connected, the highest required blower level is always selected.
• In automatic mode, the blowers are not switched off, but continue to run at a minimum level.
•Note: VOCs are volatile organic compounds in the form of gases, such as cigarette smoke, perspiration, kitchen odours, etc.

AEROMAT VT WRG 1000 Operating and Care Instructions
Commissioning
Automatic calibration of the CO2and VOC sensors (if installed)
Important: The membrane key must not be pressed during the process in order to prevent incorrect calibration.
• The sensors are calibrated automatically as soon as the AEROMAT VT WRG 1000 is connected to the mains power supply
(and also following a power failure).
• The calibration is signalled via LED indicators.
Operation
Ventilation without blowers
1. Open both locking bolts
2. Position 0 - blower off
Ventilation with blowers
Note: Depending on the design, the membrane key is positioned on either the left or right of the AEROMAT VT WRG 1000.
If it is on the right, the membrane key is turned 180° (see figure).
1. Open both locking bolts
2. Depending on the unit design, set the required blower level using either the membrane key or the external switch

Operating and Care Instructions AEROMAT VT WRG 1000
Setting the blower level (using the membrane key)
• By pressing the membrane key several times, you can activate the required blower levels and automatic mode (relaying).
• Automatic blower mode is only available if the unit has been fitted with sensors.
• Following a power failure, the AEROMAT VT WRG 1000 switches to the last level to be used (automatic sensor calibration is
performed first in units with sensors, see page 4).
*In automatic mode, the blowers are not switched off, but continue to run at a minimum level.

AEROMAT VT WRG 1000 Operating and Care Instructions
Setting the blower level (using the external switch)
• By pressing the external switch, you can activate the required blower levels and automatic mode directly (without relaying).
•Attention! If the membrane key is pressed when an external switch is installed, the next blower level will be activated (for
sequence see page 5). Pressing the external switch again takes you back to the required blower level or automatic mode.
• Automatic blower mode is only available if the unit has been fitted with sensors.
• Following a power failure, the AEROMAT VT WRG 1000 switches to the last level to be used (sensor calibration is performed
first in units with sensors, see page 4).
*In automatic mode, the blowers are not switched off, but continue to run at a minimum level.

Malfunctions and warning messages
Care and maintenance
Important: When cleaning the AEROMAT VT WRG 1000, do not allow liquids to get inside the unit.
• Clean the AEROMAT VT WRG 1000 with a cloth moistened with a mild soap solution or cleaning agent.
• Never use cleaning agents that are aggressive or contain solvents or sharp-edged objects, as these may damage the surfaces
of the casing.
Cleaning and/or replacing the unit and its parts
• Condensation does not generally develop. If the surface of the heat exchanger becomes wet for a short period, as can happen
in damp locations, for example, the moisture will dissipate quickly with the outgoing air.
• For units without filters, we recommend randomly checking and, if necessary, cleaning the insect grille every 6 months.
• The air passages and heat exchanger are to be randomly checked for contamination and, if necessary, cleaned every 12
months.
• The filters should be replaced if the LED indicator lights up. However, we recommend replacing the filters at least every 12
months.
* Important: Filters must be replaced not cleaned. Only use genuine filters from SIEGENIA. You can purchase replacement filters
from SIEGENIA or from specialist retailers.
