From the developer:
PHWIN is the possibility of accessing the user interface of the Kieback&Peter building automation system from any MS-Windows operating system. This means that the GLT central unit can be operated without restriction from any MS-Windows PC via a network or modem connection.
This is possible thanks to the client-server concept of the Kieback&Peter GLT central units.
