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!

Dear Valued HomeDepot Customer,
We reached out to the MFG for more information and below is their response.
"The TN311 is a 15amp indoor rated timer. It will control lighting as long as the timer is being used indoors and you are using less than the 15amp current rating. "

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?

15-Amp Heavy Duty Indoor Plug-In Dial Timer is rated 4.6 out of 5 by 65.
Rated 4 out of 5 by from Only kept 2 out of 6 Didn't realize plug into oulet was 3-pronged. House was built in 1961 so most outlets take 2-pronged plugs and this unit should not be used in extension cords.Exchanged 4 pieces for 2-pronged version which I hadn't noticed in my original search

Rated 5 out of 5 by from 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.

Rated 1 out of 5 by from I purchased a water distiller from Amazon which boils water to create clear water. It runs for 4 ... I purchased a water distiller from Amazon which boils water to create clear water. It runs for 4 hours and creates 4 liters of crystal clear water however the fan is noisy and they expect the water to boil dry which can't be good for the heating element. So I bought this timer so I could run it at night for 3 1/2 hours. Result is that I don't hear it and I am confident that the machine will last MUCH longer. It is also easier to clean since I just tip away the 'bad' water and don't have to scrub the container. Spending $4 to protect a $120 distiller is well worth it. VERY pleased.

Rated 5 out of 5 by from Excellent product... Timer is accurate, quiet, and is easy to set. My only complaint is with the directions. There is no explanation concerning the function of the "automatic override wheel". Despite that, the timer worked well. I was able to program three different on and off times, which worked well for me in my absence. I purchased three of these timers and I highly recommend this product.

Rated 1 out of 5 by from 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.
