Product Overview

The ET8000 Series 7-Day Astronomic Time Switches by Intermatic feature independent 7-day programming to provide flexibility for applications where load switching differs each day of the week. They provide dependable and uncomplicated performance plus to-the-minute programming for accurate load control and reduced energy costs. Up to 56 set points (28 on/28 off 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. All models come with 2 industrial grade AAA alkaline batteries to provide time keeping and automatic carryover for a minimum of three years. The batteries are easily replaced. Each time switch is housed in a lockable enclosure to protect from vandalism and unauthorized tampering.

I want to replace my Intermatic mechanical timer Model T101P, which is housed in a plastic all-weather case, with this programmable, Astronomic switch

1) Will the Astronomic switch fit in the existing outdoor enclosure, and 2) Can I buy just the switch without the indoor box shown?
Asked by: PAF
I've done exactly the same thing - ONLY indoors:-) I'm sure it will fit (the guts) inside your weatherproof (NEMA 3R) box. My free advice: Ask Intermatic if they have one with weather proof (NEMA 3R) enclosure. If they do (I am sure of that), then ask the good people at Home Depot to get it for you. For your Q#2: Again ask Intermatic first, then Home Depot will get it for you! I have a PDF telling you all about it, but this silly site refuses to load it up (only 986KB), so here is p1 as a JPEG...I hope they will fix this page! .

how does it know when to shut off and turn on. Do I put in zip code or some location info.

Asked by: Metz
Yes, they ask you (in the setup) and you enter NORTH (for Michigan) or wherever your State falls in the little map you see there. Also, you can leave it alone and it will follow the sun thru the seasons. Or you set, say, the sunset as the actual time (as listed for the date on many sites on the Internet), then deduct 30 minutes to allow for any dark, stormy afternoons. So, if the listed sunset time for Dec. 04 is 17:02 (or 5:02 PM), you set it for 4:32 PM (16:32) so the lights come on 30 mins before the actual sunset! You can do same for the sunrise... It is a lot simpler than it sounds :-)
