The Gira Control 19 Client 2, a touch screen PC for control of the KNX installation via the Gira HomeServer or FacilityServer, is provided with completely revised hardware. Thanks to technical progress in the computer field, components are available, from the display through the mainboard to the power supply unit, which perform their tasks in a reliable and energy-efficient manner. The maximum energy requirement was reduced from 39W to 24W, in standby mode even from 5W to just 1.1W. Less power loss also means less waste heat and therefore a higher and longer service life. The Gira Control 19 Client 2 is operated using a large and brilliant display with a screen diagonal of 47 cm (18.5"), which clearly displays all building technology functions via the Gira interface.
