14.3. Safety devices
B
To ensure safe operation of the system, safety devices and covers must by no means be rendered inoperative; nor
may measures be taken to bypass or dismantle them.
In the event of any errors or defects on the ventilation system, which may cause harm to persons or property, the system must be put
out of operation immediately or be protected against restart. Further use must be actively prevented until the unit is fully repaired.
The unit may only be repaired by a specialised company.
14.2. System diagram
1. Supply air (SUP)
Supply air is the air supplied to the room.
2. Extract air (ETA)
Extract air is the air that is extracted from the room.
3. Outdoor air (ODA)
Outdoor air is the air that is drawn in from outside.
4. Exhaust air (EHA)
Exhaust air is the air that is blown out into the open.
5. Enthalpy exchanger
Serves to transfer heat and recover humidity from the warmer to the colder air.
6. Outdoor air fan
Provides for the required air volume flow in the supply air.
7. Exhaust air fan
Provides for the required air volume flow in the extract air.
8. Controller
The ventilation unit is regulated in a demand-oriented fashion via the VOC/eCO2 sensor system integrat-
ed into the ventilation unit. The ventilation unit can be controlled optionally by using the pushbutton on
the unit, via Pichler APP or via the “MINI” control unit.
9. Outdoor air flap
Closes the outdoor air connection of the unit when the unit is switched off.
10. Exhaust air flap
Closes the exhaust air connection of the unit when the unit is switched off.
11. Outdoor air filter ISO Coarse 70%
Serves to pre-filter the outdoor air and to protect the unit interior.
Furthermore the filter replacement intervals of the supply air filter are prolonged.
12. Supply air filter ISO ePM1 55 %
Serves to filter particulate matter in the supply air.
13. Exhaust filter ISO Coarse 70 %
Serves to filter the coarse impurities from the extract air, in order to protect the unit’s interior from
being contaminated.
14. Cable inlets
Electric connecting cable
15. Supply air connections for multi-room
applications
Serves to provide the KOMFLEX system connection with the possibility of ventilating further rooms.
16. Extract air connections for multi-room
applications
Serves to provide the KOMFLEX system connection with the possibility of air extraction from further
rooms.
17. Electric pre-heating battery
Provides protection against the formation of condensate and against freezing in the heat exchanger at
very cold outdoor temperatures. The optional electric pre-heating battery serves to preheat the outdoor
air as a function of the outdoor and exhaust air temperature.
