6. Installation
6.1 Prerequisites for installation
• The position from which the outdoor air is drawn in must be selected so that any nearby emission sources have as little
impact as possible on the quality of the air being drawn in.
• The maximum permissible area load is 1,000 kg per running metre of ventilator length.
• Installation options:
Installation in the window sill Concealed installation in the wall
with wall duct
Installation in the window lintel Concealed installation in the window lintel
6.2 Additional requirements for AEROMAT VT WRG 1100 smart
• The AEROMAT VT WRG 1100 smart should be installed to be as free from interference as possible.
The following interferences can have a negative influence on the WLAN signal:
- Water pipes
- Stone and concrete walls
- Metal objects
- Air conditioning units
- Wireless devices (e. g. radio telephones, baby monitors, Bluetooth loudspeakers, etc.)
- WLAN networks on the same wireless channels (e. g. the neighbour's WLAN router)
• If energy-carrying cables are routed in parallel to data cables (ISDN, DSL, etc.), this could lead to interference e.g. in the
speed of the data transmission.

6.3 Installation sequence
1. Remove the AEROMAT VT WRG 1100 carefully from the packaging and do not place it on the weather grille or front
panel. We recommend storing the unit on a soft surface (e.g. cardboard or sheet) during installation.
2. Close the sliders on the front to prevent dirt (e.g. dust) from entering the unit during installation. If the
AEROMAT VT WRG 1100 does not have sliders, tape up the recesses in the front panel with film.
3. Make sure that no dirt and liquids can get inside the AEROMAT VT WRG 1100 including the weather grille prior to the
installation of the exterior insulation or cladding.
Attention! According to the installation location, it is therefore necessary to adhere the AEROMAT VT WRG 1100 at points
where rain could permeate.

7. Mains supply
Depending on the design, the AEROMAT VT WRG 1100 is connected to a suitable socket of the 230-V AC mains power
supply using the Euro plug or directly to the 230-V AC mains power supply using an external switch.
7.1 Socket connection
Important: When installed in damp locations, the socket for the AEROMAT VT WRG 1100 must be installed in at least
protection class3.
› Insert the Euro plug into a suitable 230-V AC mains power supply.
7.2 External switch connection
Exposed electrical components.
Risk of fatal injury from electric shock or fire.
› 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.
› Switch off or unscrew the security devices.
Important: If the AEROMAT VT WRG 1100 is connected directly to the 230-V AC mains power supply, the customer must
install a mains isolator.

AEROMAT VT WRG 1100 Original operating instructions

8. Unit function
8.1 Ventilation with fans and heat recovery (schematic diagram)
• The outside air (1) is drawn in through the outside air filter (2) or insect grille (2, optional) using the supply air fan (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 fan (7) and makes its way outside as
exhaust air (8).
• Both streams of air are drawn through the heat exchanger (9). Here, particularly during cold times of the year, the outside
air is pre-heated by the warm exhaust air before it enters the room as supply air.
No. Element No. Element

2F7 outside air filter or insect grille (optional) 7Exhaust air fan
3Supply air fan 8Exhaust air
4Supply air 9Heat exchanger
5Exhaust air 10 Power supply, control, cable outlet, membrane key
8.2 Ventilation without fans
• When the fans are switched off and the sliders 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 ventilation). Because the fans 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 fans are not used for ventilation.
8.3 Operation in automatic mode (only for AEROMAT VT WRG 1100 Var. 2 and Var. 4 - with sensors)
• AEROMAT VT WRG 1100 automatically switches to blower levels 0, 1 or 2 according to the air quality, the temperature
and the air humidity.
• In automatic mode, the fans 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 (Example: Automatic ventilation will not take place if the outside air is relatively warm and
humid).
• If several sensors are connected, the highest required blower level is always selected.
*
VOC are volatile organic compounds in the form of gases, e.g. cigarette smoke, perspiration, kitchen odours, etc.

• The calibration is completed after approx. 20 min.
Requirements for a faultless calibration
• The room must be well aired before the calibration.
• The room temperature must be between 5°C and 40°C.
• There should be no persons or animals in the room.
• The membrane key must not be activated during the process.
11. Operation
11.1 Ventilation without fans
1. Open both sliders
2. Set the blower level to 0
11.2 Ventilation with fans

11.2.1 Adjustment of 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).
• The automatic mode is only available in designs with sensors
(AEROMAT VT WRG 1100 Var. 2 and Var. 4).
• Following a power failure, the AEROMAT VT WRG 1100 switches to the last level to be used (automatic sensor
calibration is performed first in units with sensors, see page14).

11.2.2 Adjustment of 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 switching sequence see page 15). Pressing the external switch again takes you back to the required blower level
or automatic mode.
• The automatic mode is only available in designs with sensors
(AEROMAT VT WRG 1100 Var. 2 and Var. 4).
• Following a power failure, the AEROMAT VT WRG 1100 switches to the last level to be used (sensor calibration is

12. Care and maintenance
Electrically operated unit.
Risk of fatal injury from electric shock or fire.
To prevent personal injury or damage to property, always comply with the following instructions:
› Pull the mains plug out of the socket prior to every cleaning process or maintenance work. Never pull at the cable to
disconnect the device from the electricity grid.
› For all devices with a fixed connection to the 230 V AC mains power supply, switch off all poles of the feeder. The fuses
may need to be removed.
12.1 Cleaning
Important: When cleaning the AEROMAT VT WRG 1100, do not allow liquids to get inside the unit.
• Never use cleaning agents that are aggressive or contain solvents, or sharp-edged objects, as these may damage the
surfaces of the casing.
• Never clean the unit with a high-pressure cleaner or steam-jet cleaner.
• Clean the AEROMAT VT WRG 1100 with a cloth moistened with a mild soap solution or cleaning agent.
12.2 Maintenance intervals
Component Check and clean Replace
Insect screen Every 6 months ―
Air ducts and heat exchanger3) Every 12 months ―
Filter4) ―Every 12 months or when the filter
change notification illuminates
3) 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.
4) Filters must be replaced, not cleaned. Only use genuine filters from SIEGENIA. You can purchase replacement filters from
SIEGENIA or from specialist retailers.
