Pichler control and regulation system
Modular central comfort ventilation units are equipped with integrated Pichler control and regulation as standard.
All the ventilation units settings are possible via the integrated Web server. The Web server has an integrated
for days and weeks. Current operating status and system settings such as control mode, ventilation
level, temperatures etc. are also shown on a control unit. Signal lamps will indicate
normal operation (green) or
malfunctioning (flashing red); these conditions are also displayed
in plain text. A graphic control unit with a touch
screen allowing more accurate settings to be made for the ventilation
unit is under development.
The PI-Air2 system is a simple, user friendly, intelligent controller for ventilation units. It will guarantee maximum comfort and minimum energy consumption. This system is included in all Pichler ventilation units, starting from LG750.
- Simple operation via control unit or integrated Web server
- Modular, demand-optimised system
- Clear overview of current operating parameters
- Simple integration into automated building systems
- Extensible via PI optimiser system for demand-optimised room zone regulation
- Safety functions: Fire Alarm shut down, Smoke detector integration and more

The newly developed Pichler System Optimiser will regulate the supply and extract air fans in central ventilation equipment to match demand, achieving energy efficient and optimised operation of the plant. LG750 - LG 6000.
25 zones (50 flow regulators) per section
may be controlled via a zone optimiser
system for the sections, developed
in-house. This system may, if
required, be extended to up to 5 sections,
each with 25 zones - i.e. 125
zones in total (250 flow regulators). The individual zones may each
be parameterised and monitored
or via the integrated Web
In addition to the air volume parameters Vmin, Vmax, additional flow regulator parameters may be controlled via the Web server. Current flow regulator operating parameters (e.g. flap position, current flows, etc.) will be passed on to the central optimiser via a Modbus system. These are used to calculate optimal fan speeds to thereby control all flaps in optimal operating position.
The central reference and control variable of this need-based system will be the flow regulator flap position. This will significantly reduce the power consumption of the fans. The reduced airflow noise over the flap wings will furthermore clearly benefit user comfort.
Advantages compared to constant pressure control: Significantly lower energy consumption of the fans, less airflow noise, optimised regulation achieved by central control of all flow regulators.
