HVAC/R graphic touch-screen user interface

Design & Technology: graphic touch-screen user interface pGD2 and pGD3 are two extremely high-tech user interfaces, featuring a 5.7” touch screen display with 1/4 VGA resolution, and a 32-bit microprocessor that allows the management of complex graphic images (up to 320x240 pixels in size and with up to 256 colours), animated icons, non-proportional fonts in Unicode format, graphs of the alarm trends, temperature, humidity, pressure values and air speed. The touch screen function makes it easy for the user to manage more complex installation diagrams, without losing the overall view of the installation, as well as ensuring that the pages can be browsed in a fast and straightforward manner, thus reducing the use of manual instructions. A keypad on the side of the display can be used in all applications where the touchscreen is not the preferred solution. pGD2 and pGD3 can be connected to external keypad modules, thus offering more demanding manufacturers in the HVAC/R market various possibilities for customisation and differentiation. The higher technological content is also expressed by the appearance of this device, designed to exploit the wide screen and the shape that can be easily adapted to any installation (on board the unit or in the room). For lower-end applications, the black and white version is available, which still supports the same functions as the colour version
