Introduction to the Preloaded Applications Introduction to the Preloaded Applications Distech Controls’ ECL-PTU controllers come preloaded with code containing standard applications. This code was created using EC- gfx Program, a Graphical Programming Interface (GPI) tool that en- ables visual assembly of building blocks and the design of custom programs that control Building Au- tomation Systems.
EC- gfx Program user guide, both of which are available on the Distech Controls website. This user guide only explains hardware installation in a general sense. Please refer to the individual device’s installation guides for specific hardware installation information.
