7-Day Electronic Astronomic Time Switch
The ET8000 Series 7-Day Astronomic Time Switches feature independent 7-Day programming to provide flexibility for applications where load switching differs each day of the week. These time switches provide dependable and uncomplicated performance, plus to-the-minute programming for accurate load control and reduced energy costs. Up to 28 ON/28 OFF (56 events) can be preset to automatically repeat. Each event can be applied to any combo of circuits and days. Each circuit is provided with an independently scheduled Astronomic ON event and Astronomic OFF event. The program can be disabled at an time by placing the time switch in the Manual operating mode. Control buttons provide manual control of each circuit independently regardless of the operating mode. All models come with two industrial-grade AAA alkaline batteries to provide time keeping and automatic carryover for a minimum of three years. The batteries are easily replaced in the eld without requiring removal of the time switch mechanism or eld wiring. Each time switch is housed in a lockable enclosure to protect from vandalism and unauthorized tampering.
