Landis & Staefa Controls offers DESIGO PX building automation and control system controls which monitors heating, ventilation, air conditioning and other building services plants. It is distinguished by its unique scalability of freely programmable automation stations, range of graded operator units as well as a high degree of system openness.

DESIGO PX can adapt to the requirements and needs at hand thanks to its modular system design. The DDC technology can even be used economically and at low cost in small HVAC plants. The investment is limited to the system components that are actually needed for both new construction and remodeling. Thanks to its innovative system design, DESIGO PX can be extended at any time and in stages to a comprehensive building automation and control system.
