Channel 1 is also available on a physical relay, the other eight act on the bus, and together they hold 450 programs with 900 switching events including sunrise\/sunset times offset by up to ±120 minutes.\u003c\/p\u003e\n\u003cp\u003eThe clock keeps time with a replaceable CR14250 battery, handles daylight-saving changes automatically, can be synchronized from the ES01A00ACC GPS module, and is operated from the front in five languages with password protection. It suits facade lighting, retail opening hours and any installation that must run fixed schedules independently of a visualization server.\u003c\/p\u003e\n\u003cp\u003ePrograms are entered on the front panel or copied between devices, and each channel sends its state to the bus as a 1-bit object that any actuator or scene controller can use. Holiday periods and one-off date programs override the weekly schedule, and the astronomical function uses the site coordinates (entered manually or received from the GPS module) to calculate daily sunrise and sunset. Because the schedules are stored in the device, they continue to run if a visualization server or network is down.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e9 channels: channel 1 on relay and bus, channels 2–9 on the KNX bus\u003c\/li\u003e\n\u003cli\u003e450 programs \/ 900 events; weekly, date and holiday schedules\u003c\/li\u003e\n\u003cli\u003eAstronomical function with ±120 min offset on sunrise\/sunset\u003c\/li\u003e\n\u003cli\u003eAutomatic daylight-saving switching; GPS time sync via ES01A00ACC\u003c\/li\u003e\n\u003cli\u003eFront-panel programming in 5 languages; password protection\u003c\/li\u003e\n\u003cli\u003eCR14250 backup battery for the clock\u003c\/li\u003e\n\u003cli\u003eDIN-rail mounting\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eChannels\u003c\/td\u003e\n\u003ctd\u003e9 (channel 1 relay + bus; channels 2–9 bus)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePrograms \/ events\u003c\/td\u003e\n\u003ctd\u003e450 \/ 900\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAstronomical offset\u003c\/td\u003e\n\u003ctd\u003e±120 min\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTime synchronization\u003c\/td\u003e\n\u003ctd\u003eES01A00ACC GPS module (optional)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBackup battery\u003c\/td\u003e\n\u003ctd\u003eCR14250\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLanguages\u003c\/td\u003e\n\u003ctd\u003e5\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMounting\u003c\/td\u003e\n\u003ctd\u003eDIN rail\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCertifications\u003c\/td\u003e\n\u003ctd\u003eKNX certified; CE\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eETS application\u003c\/td\u003e\n\u003ctd\u003eES01A00KNX time switch application\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight (net)\u003c\/td\u003e\n\u003ctd\u003e0.2 kg (0.44 lb)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eManufacturer part no. \/ GTIN\u003c\/td\u003e\n\u003ctd\u003eES01A00KNX \/ 8054144521145\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003ch3\u003eRelated Products\u003c\/h3\u003e\n\u003cp\u003eAccessory: ES01A00ACC GPS receiver for time synchronization.
