7-Day Electronic Astronomic Time Switch
The ET8415CR 7-Day Astronomic Time Switch features independent
7-Day programming to provide flexibility for applications where load
switching differs each day of the week. This time switch provides
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 combination 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 any
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. The ET8415CR comes with a 100 hour
supercapacitor to provide time keeping and automatic carryover with
no maintenance. The time switch is housed in a lockable enclosure to
protect from vandalism and unauthorized tampering.
