What setting should this timer be on to run every day from dusk until dawn based on astronomic time? ON, Auto? or something else?

The HB880R timer needs to be set to Auto in order to operate from dusk to dawn, however sunset time (with sun and moon in the corner) has to be selected under Event "1" so the timer will follow astronomic time. Instructions are a little vague, but if you require assistance call Intermatic at 815-675-7000; they are very helpful.

I have mine on a timer, not dusk to dawn, so I really can't comment on that. My setting is on AUTO.

Yes, I set it every evening for 5:00 a.m. the next morning for my husband and he has coffee waiting for him when he gets up at 5:15! A blue dot lights up on the panel so you know the auto is set, and you can check the set time with a push of a button! Works perfectly every time!

Its always on. I bought an outdoor timer to turn it before dawn on snowy nights and late in the day on snowy days. In light of this real bad winter we're having, this is one of my better purchases.

If I remember correctly, you turn the dial to the current time (AM or PM) and then move the abs for the times you want it to run opposite of their current position. For example if it is 7 pm and you want it to come on at 8 move the tab/selector on the 8 pm one. Ours is outside in the dark and cold or I would go look. If no one has a better answer I will look at mine after work tomorrow. Does a great job running the pool filter all summer!! Set it and forget it!!

I plug mine into a timer that I got at the hardware store. It comes on at 10 and goes off at 12. The "nebula" will come on with the timer but you have to switch on the stars. They both go off with the timer though, 4 hours was just too long. Good luck

I just figured out how to shut off the AUTO SET and the DST settings. Thanks for your help!

just purchased this and have not set any daily modes for the week, but activated the vacation security mode to see how the random on and off light feature worked. I've also set the day and correct time in this unit,, so far for the last 2 nites, the unit has turned on the lamp at around 6PM but I've manually turned off the unit late at nite before I go to bed because it stays on. during the day, it stays off. I can only surmise that I have to set on and off times for each day & that the random timer works off of that,, otherwise it does not appear to do the random on and off.

This is an excellent timer, and I have installed several. However, if you use the automatic DST feature to constantly adjust the "ON" time as the seasons change, then the length of time that the lights remain "ON" will constantly change as well. What I means is that in the programming mode, you would have to select a specific time for the lights to turn back "OFF". If the current automatic DST sunset brings the lights on at 8:00pm, you could program the "OFF" time as 10:00pm. However, in a few months the sunset time will automatically adjust to 5:30pm (depending where you live of course) however the "OFF" program will remain at 10:00pm. In most cases this isn't a problem, in fact it's usually a convenient solution for most lighting control. Hope this helps. P.S.- I find these timers to be way easier to program than any other in the wall timer I've encountered, and there are no batteries to change.

If you are looking just to adjust for DST the is a switch on the bottom that handles that. If you are setting the time there are several buttons on the bott of the unit.

I did not try to set any times like you asked. I use it for 6 hrs per day 7 days per week. Works fine except for relay problem which is "sometimes". I slight knock fixes it for awhile.

Not sure about that, placed mine on automatic for when it became dark enough, and used the longest setting, whatever you think the item works very well!

If that is what you want a light sensor might be a better choice. There are socket adapters readily available with sensors. As 'crazy for christmas' pointed out, this timer can be programmed to come on at sunset and remain on a set number of hours, which could be changed as the season progresses to be close to dawn.

Yes, the easiest way is to plug it into day/night sensor plug. That way it comes on automatically in the evening and goes off at dawn.

When you go into the manual set up mode the first thing you see is either ST or DT in the day portion of the display. Use the up arrow or the down arrow to set it for DST or not. This does not appear to be in the instructions, but mine works this way.

It's just a timer. It doesn't do day or night time settings. You set it for however many minutes or hours you want and it simply counts down.

We run our system 24/7 so we have it on both. You just set the interval you want and the duration of each event.

My husband installed it and I remember him complaining about the sensor being only controlled by sunlight (dawn to dusk). So we ended up putting a programmable timer in the series and plugged that into the outlet. Involves some wiring but simple enough.
