ABB i-bus ® KNXGeneralTR/A 1.1 | 2CDC509082D0201 51.2 Overview of product and functionsThe Time Receiver GPS is used to receive the current time and to send it on the KNX bus. This allows theTime Receiver GPS to act as the internal clock for every time switch or also for devices with time-dependent logic. Furthermore, its integrated brightness and temperature sensor can transmit additionalexterior conditions on the KNX bus.The device can be operated anywhere in the world by using the GPS signal.The device is intended for surface mounting on the outside wall of a building. It connects to theABB i-bus® via a bus connection terminal inside the device. The device can be operated, e.g. forcommissioning, by applying an auxiliary voltage to the bus terminal. The physical address is assigned andthe parameters are set using the Engineering Tool Software ETS.The following information can be sent on the KNX bus:• Time• Geographical coordinates• Time progression of the solar irradiation angle over the course of the day• Sunrise time• Sunset time• Brightness value (via integrated brightness sensor)• Outside temperature (via integrated temperature sensor)Furthermore, a simple time switch and an Astro time switch are available. It is also possible toparameterize switching thresholds based on measured temperature and brightness values and to send asignal on the KNX bus if these thresholds are exceeded. This allows, for example, exterior lighting to beswitched on/off based on the brightness or the heater to be switched on when the outside temperature fallsbelow a certain value.
