Description

The Intermatic ET8000 Series Electronic Astronomic 7-Day Time Switch automatically switches loads to a preset weekly schedule with to-the-minute accuracy.

• The astronomic feature provides an automatically adjusted sunset ON and sunrise OFF to eliminate the need for separate photo control devices.
• The independent 7-day programming provides complete flexibility forapplications where load switching differs each day of the week.
• Astronomic programming can be combined with independent programming to provide a sunset ON and timed OFF program.

Use the ET8000 series as an ON/OFF timer in applications requiring 7-day astronomic load control such as lighting, air conditioning systems, pumps, etc. Each load output of the Time Switch can support up to 14 timed ON and 14 timed OFF events per day as well as Astro ON and Astro OFF events. The program can be overridden by pushing the ON/OFF load override button(s). The ET8000 Series Time Switch is designed to directly switch tungsten or ballast loads up to its rating, and inductive or resistive loads up to 30A at 120, 208, 240, or 277 VAC.
