Question 1

What happens if the power goes out?  Does the timer remember the settings, or does it reset?

Accepted Answer

I just spoke with an AUBE tech (owns Honeywell) about this astro timer on 8/07/19. He told me they use a super capacitor now that will hold the time AND program settings for a period of approximately 2 hours during a power outage. After two hours of the power being off, the time of day will need to be reset, but the program should still remain intact.

Question 2

I know it can self adjust the time based on coordinates, but can you program it to leave the lights, etc. on for only 2 hours after being turned on?

Accepted Answer

Yes,

You can program 7 separate on/off times. In my case, I have it scheduled to turn on at sunset and off at sunrise (all week). This is 1 program. I still have 6 programs remaining.

So you could schedule random on off times for any day of the week you wish. For instance, on at 8:00pm and off at mid-night (Monday, Tuesday, and Friday). This would be 1-program.

Question 3

Can it be used to replace a switch in 3-way switch

Accepted Answer

It can be used to replace a 3-way switch!  The other switch becomes unusable is my understanding though.  I installed this switch in what was a 3-way configuration using the instructions from this review of this switch: http://www.amazon.com/gp/review/R1CGCNTF3U776D?ref_=glimp_1rv_cl

Question 4

Does this require a neutral wire? I only have 2 switch wires.

Accepted Answer

Yes, a Neutral is required.    You must have  3 wires in total.   Hot, Neutral, and Load.     You CANNOT use a ground as your Neutral.    If you are not sure which wire is wich then please consult an electrician.     Please be aware that not all switches require a Neutral.   Dumb switches only require a Hot and a Load.   Years and Years ago they only wired switches with the Hot and Load.   It was until around the 70s that the neutral was included at the switch point.  Prior it was only located at the load.    Load  = the device that you want to control with the switch such as a light, motor, etc..
