As many as you like. There is the grey little swiches that let elecricity out. All you to is put up the grey swich and light will turn on for that time.

Any fifteen minute increment can be set to on or off.. So, I guess thats 96 - or 48, depending on whether you count On & OFF as one or two.

You can set it to turn on or off every 15 minutes of each hour for the full 24hr time period (there are 96 little switches), so it is very versatile and works quite well. I paid $6.99 here on Amazon and it was well worth it. It has been running flawlessly for the past 6 months.

Up to 8 times (every 4 hours). However, you can program it to be on continuously if you set each time for the full 240 minutes (4 hours).

Sure, it's like leaving any light on. Don't think about it much. I've had no problems at 18 hours a day for months at a time. It's a nice little unit.

Change once a day. Or every other day if you use the way I do which is only use at night

You can run individual zones on the timer up to 4 times a day. It also allows you to manually water any zone now by setting the zone you want, and pushing the "water zone now" button.

Yes. There are 7 on-off cycles that you can program to turn on and off any single day or MTWTF or SS or MTWTFSS. So you can have 7 separate on-off periods. But make sure your heater is not more than 15 amps.

I don't believe you can specify which days like your example. If your electronic is only plugged in the device during those days, it would still provide what you want. You can also hit a single button to turn it off on days you don't want it operate... You would just have to push it every day.

Yes. You can set on/off cycles for each day of the week, multiple days or all of the days.

No programmable days. It only has two on/off settings per day. So, program 1 and 2 are same seven days of the week.

Yes, you can set up to 3 on/off times on either different days or all on the same day.

If I am not mistaken they use AA, about 4 to 6 per light. They will actually program themselves to come on/off during the times you use them the most.

Though I don't actually use multiple programs, the instructions state that you can program the timer up to 7 different time periods. And using the same on/off times for every day of the week counts as one program, not seven. Hope that helps.

it can be set for two modes to feed a certain amount throughout the day or it could be set for one time a day at a certain time or up to three times a day at the times of your choosing. Be forewarned this item is very noisy when it runs. Also make sure you use premium alkaline batteries. It is very flexible in it's programming you can set it to feed A large amount in the morning or a small amount in the middle of the day and a large amount at night or any combination thereof. Personally I will give this unit three out of four stars. Only two things I wish it had A quieter mechanism and a AC power adapter using the batteries as a backup. it can be set for two modes to feed a certain amount throughout the day or it could be set for one time a day at a certain time or up to three times a day at the times of your choosing.

No. It will not do 24 on-off cycles per day. The limit is 8. Also it has a minimum on time of 1 minute.

One. I don't use it every day but when my skin gets sensitive I use it and it works well. Be sure to keep it clean. I think it is worth trying. good luck. Ed

I keep mine on for 30 minutes a day anyways. i just figure the longer they're on the better. 5 minutes seems a bit to quick to me.

Just turn it on at the time you want it to turn on each day. After the first time, it will do so at the same time each day and be off the other 19 hours.
