Answer: 
You will need a timer capable of separate settings for each day, and set it so that the charging only occurs one day a week, for 3 hours. The DT620 15-Amp Heavy Duty Plug-In Digital Timer is a good fit for this application.

Answer: 
The maximum capacity of the timer is 15 amps so provided the fixtures and line length resistance is within this capability it should work fine; however, this is an indoor timer and must be protected from the elements.

Answer: 
It should, as it will handle 15 amps. However, this is an indoor timer and should be well protected if used outside!

If the amperage of the BUT 6000 is less than 15 amps and the timer is placed indoors, the answer is yes; however, note the unit will operate only during the period the timer is on.

Answer: 
A modern air conditioner of this BTU rating should consume approximately 5 to 6 amps at 110VAC so, yes, this timer can safely control a 6000 BTU air conditioner.

I see that most new timers do have a manual override, but they don't automatically turn off when it hits the next off time. An older sears timer allows this. Do any new timers have this feature?

Rated 4.6 out of 5 by 52 reviewers.
Rated 1.0 out of 5.0 by Did Not Work Very simple to install so it could not have been an incorrect installation that caused the timer not to work. I am going to return it when the digital timer that I ordered as a replacement arrives at the store. October 18, 2016
Rated 5.0 out of 5.0 by Excellent product and easy to set up. I highly recommend it. Just purchase 2 more timers. This product is very long lasting and is very easy to install and use. August 9, 2016
Rated 5.0 out of 5.0 by Great Timer I love mechanical timers. Failure rate on digital are to high. Bought 2 digital and 1 did not work. These a basically fool proof. August 16, 2016
Rated 5.0 out of 5.0 by Good reliable timer. This heavy duty Intermatic timer is used to switch several lamps on and off daily. It is well made, very reliable and trouble free. August 9, 2016
Rated 5.0 out of 5.0 by Fine timer This timer is easy to set and use. The option of using three different "on" periods is a great plus. And it is a heavy duty product, too. August 2, 2016
Rated 5.0 out of 5.0 by Excellent Product Works just as advertised. Solid made and very dependable June 28, 2016
Rated 2.0 out of 5.0 by Time is what you make of it the first timer i ordered was 50% slow, and would run 1/2 day in a day. The second one was right on the mark, and the third one runs a half hour slow in a day. if you can get one that is correct timewise it is very durable. June 21, 2016
Rated 5.0 out of 5.0 by Fantastic purchase for our LG window AC unit. I needed a timer to run our LG window AC unit to cool our apartment down before we got home from work on summer evenings. This timer is exactly what I was looking for. It is programmable for up to three different times per day. The manual override is also a nice feature. The only downside is you have to order it online and ship it to the store or your home. I would definitely recommend this to someone looking to use it with an AC unit. June 23, 2016
