2.3. Overview of components
With the ventilation unit LG100 you can provide a maximum degree of flexibility to your ventilation concept. Depending on the design
variants of the flush-mounted housing, further rooms can be integrated via the KOMFLEX air duct system. The used air is extracted
from the living areas, and fresh, filtered outdoor air is supplied. In this process, the high-quality enthalpy exchanger allows for
ecient heat and moisture recovery and ensures a well-balanced room humidity and a pleasant room climate.
Highly ecient and low noise EC radial fans allow for extremely energy-saving and low-noise operation. In the switched o state,
the outdoor and exhaust air openings are automatically closed mechanically. The integrated sensors record the VOC and eCO2
concentration of the extract air and, in automatic mode, allow for an operation depending on the room air quality.
The decentralised compact ventilation unit LG100 is controlled easily and intuitively via a pushbutton that is positioned directly on the
unit, or via the PICHLER APP. Therefore the unit comes with a WLAN connection as a standard feature. Optionally you can additionally
connect an external control unit via cable connection.
3. Functionality of the ventilation system
4. Designated use
4.1. Intended use
The compact ventilation unit LG 100 is intended for the installation into ventilation and air conditioning systems for controlled
domestic ventilation in small and medium-sized residential units (approx. 80 m²). The purpose of controlled mechanical ventilation
and deaeration of domestic areas is to improve air quality and reduce the heating energy demand through the use of a highly ecient
heat recovery system, and to influence indoor air humidity. The scope and intended use of the unit is limited to the application in
residential and recreational spaces for the suction of used air and the supply of fresh, tempered outdoor air at maximum air flow
temperatures of -15°C to +35°C. Furthermore the airflow must be free from aggressive vapours and substances causing increased
wear. Any other use shall be deemed contrary to designated use. The manufacturer shall accept no responsibility for damages
or consequential damages arising from improper use. Designated use also includes adherence to our prescribed operating and
installation manual. This unit is available to the general public and is intended for installation in residential or industrial buildings. The
unit is used for mechanical aeration and ventilation of indoor air and, when combined with a heater battery, is also used to preheat
air. The compact ventilation unit LG100 is not suitable for outdoor installation and may be installed in suitable and frost-free interior
areas only. The ventilation unit is not suitable for drying new buildings.
This unit can be used by children from an age of 8 years and furthermore by persons with reduced physical, sensory or mental
capabilities or a lack of experience or knowledge, if they are supervised or if they have been instructed on how to use the unit safely
and if they understand the hazards resulting therefrom. Children must not play with the unit. Cleaning and user maintenance must
not be carried out by children without supervision.

The compact ventilation unit is not a ready-to-use product. It must not be put into operation until it has been properly installed and
connected. Only qualified and instructed personnel may carry out connection and service work on the unit.
B
In order to prevent uncontrolled condensate formation in the unit, continuous operation at outdoor temperatures
below 0°C with an extract humidity of more than 60% must be avoided (e.g. private spa area).
B
Persons transporting, installing or working on the unit must have read and understood the operating instructions, in
particular Section5 "Safety". The end user must also be instructed on potential hazards.
4.1.1. STIPULATIONS FOR OPERATION WITH FIREPLACES
4.1.2. STIPULATIONS FOR OPERATION WITH EXTRACTOR HOODS
4.1.3. LIABILITY
Local requirements must be taken into consideration by compliance with corresponding standards, laws and directives.
The decentralised compact ventilation unit LG100 may only be installed in rooms, flats or utilisation units of a comparable size in
which fireplaces dependent on room air are installed, if:
• simultaneous operation of room air-dependent fireplaces and the air extraction unit is prevented by safety devices, or
• the flue gas evacuation of the room air-dependent fireplace is monitored by special safety devices. In the case of room-air
dependent fireplaces for liquid or gaseous fuels, activation of the safety device must lead to the switch-o of the fireplace or
ventilation unit. In the case of room-air dependent fireplaces for solid fuels, activation of the safety device must lead to the switch-o
of the ventilation unit.
The ventilation units for the controlled aeration and ventilation of a flat or a comparable living unit must not be installed if room
air-dependent fireplaces in the living unit are connected to exhaust gas systems, which themselves have multiple connections.
Normal operation of the ventilation systems requires the possibility of shutting potentially available combustion air ducts as well as
exhaust gas systems o from room air-dependent fireplaces. In the case of exhaust gas systems of fireplaces for solid fuels, it must
be ensured that the shut-o device can only be operated manually. The position of the shut-o device must be identifiable by the
setting of the operating handle. This specification is considered as complied with if a shut-o device against soot is used.
Fire protection requirement: With regard to the fire protection installation regulations for the set-up of the ventilation unit, the
provisions of national law, in particular the building regulation concerning the fire protection requirements with regard to ventilation
systems in the relevant latest version must be observed.
Due to the heavy load as well as the irregular operation, the extract air of an existing kitchen extractor hood must not be integrated
into the dwelling's ventilation system. Extract air from such extractor hoods must be conducted separately by means of an exhaust
air pipe via the roof. The supply air must be provided for separately (e.g. by window ventilation).
If an extractor hood without the separate provision of supply air is operated, the balance of the air volume in the dwelling is no longer
provided for and the proper function of the dwelling's ventilation system is no longer ensured (odour diversion, etc.). Another option is
to operate the extractor hood in recirculation mode.
The compact ventilation unit LG 100 has been developed and manufactured for controlled mechanical ventilation and deaeration of
spaces with purposes similar, for example, to seminar rooms and small oces. Proper use of the ventilation systems have the facility
to be shut o from fireplaces dependent on ambient air.
Any other use than the one described in Section4 shall be deemed improper and may cause personal injury or damage to the
compact ventilation unit, for which the manufacturer shall accept no liability.

The ventilation unit is switched on by pressing the operating button twice and starts running at ventilation level 1. The LED blinks
three times at frequent intervals with one green flash in each case. The outdoor air and exhaust air flap opens and the fans convey the
selected operating volume flow of ventilation level 1. With every further push of the button the ventilation unit is switched to the next
higher ventilation level. When the “Automatic” ventilation level (LED flashing green 4 x) has been reached, the ventilation unit switches
back to the “Standby” mode, and switching starts again from the first level. In the Standby mode, the fans switch o, and the outdoor
air and exhaust air flap closes. The current operating state is indicated by the flashing patterns specified in the table below.
Wake-up call:
After showing the respective flashing pattern, the LED changes to the “Sleeping mode”, the ventilation unit continuing its operation at
the ventilation level currently set.
By pressing the operating button, a “wake-up call” is carried out first and the sleeping mode of the LED is stopped. The LED indicates
the current operating status (ventilation level, error and filter messages) by the dierent flashing modes. The flashing modes are
repeated 3x, then the LED returns to the sleeping mode again.
In order to change the ventilation level, the button on the ventilation unit must be pressed after the “wake-up call” and within the flashing
pattern (3 repetitions).
The ventilation unit can be operated without a control unit via a button on the bottom side of the unit. A green LED indicates the dierent
operating states of the ventilation unit. A red LED indicates an error or a warning message of the unit. A detailed description of the error
codes can be found in Section 19.2.
