I do not know that timer.
Many older timers never had online manuals.

    I see you downvoted the free answer instead of adding a comment and giving the fixya community information about your timer that could help others. Which helps nobody. Next step would be to google your model timer and then go to one of those sites that sells the manual spyware. Download the manual spyware and then restore your computer. Afterward, post your manual for free on your website, that you pay for each month, and then send the web address of that manual to me so others can enjoy your generosity for free. Can we count on ya?

I have this timer switch also. It doesn't matter whether you push on/off button. It always runs the scheduled program ie. it automatically triggers the scheduled program at the time you have setup. This device has also the ability to setup ON or OFF at a specific time without being forced to select both.

How do you set upm model dt 420 electronic timer

Open UPM DT420 manual on following link:

The manual is longer than allowed for free answer and has important illustrations and options.
Please read the manual in addition to instructions given below.

Copied directly from the manual:
1) Select AUTO using the slide switch
2) Select the desired On-period (2, 4, 6, 8, 10 hours) using the dial switch
3) For continuous Dusk to Dawn operation, Select CONTINUOUS using the dial switch.
Timer turns ON automatically at dusk and turns off according to how you set 1 2 and 3.
If timer does not operate, or if it turns on at odd times, then it is broken.

Note: UPM manuals normally leave out important information, but this particular instruction matches closely with similar products and is probably accurate.

What is the purpose of the countdown timer? Can you program for just 1 program setting for the full week? When setting program time is the manual on/off switch in the on or off position?

You posted under UPM programmable timers
Open following link to identify product and download manual

Q1) Some UPM timers, and other brands, offer countdown feature in addition to regular programming.
So you choose between regular programming and countdown.
Countdown is for a bathroom fan for example.
Push the button and fan turns on for set amount of time.
After countdown is over, fan turns off automatically.

Q2) Yes all days of the week can be selected.
Set event 1 ON for all days.
Set event 1 OFF for all days.
Do not set more events unless you want more on-off events.

Q3) Switch position depends on model number.
Add a comment with model number to identify product and I will look at manual alongside you.
Or try the switch in different positions.

I am having a problem setting the UPM ETW350 timer, can't seem to have it go off at a certain time. What do I do about the countdown? IS that what I press to go to the time to shut it off?

You posted under UPM 350 programmable timer

Manuals for all UPM timers are missing key explanations, despite the lengthy manual.
I think there are 3 things to look for:
1) Program1 is ON and program2 is OFF and program3 is ON etc.
2) When setting days, be sure that ON and OFF are set for same days so there are no conflicting programs.
3) Timer gives three modes: Countdown and Random and Programming. Countdown is for a bath fan when you want to turn on fan with push of button and have timer turn off fan automatically after the countdown expires. Do not use countdown or random functions when you want timer to perform ordinary on-off functions.

I also am having trouble with this timer. I've got the program set for when I want it to go on but can't figure out how to put in the time I want it to stop. I don't understand where the countdown timer...

ETW350 is programmable timer that offers 3 different timer
functions: Program, countdown and random.
Timer has 20 different settings.
UPM site is not available recently, but UPM timers are still being sold.

Operation manual is not very clear how to program ON and OFF times.

That being said, usually with programmable timers, you program ON time. And then program OFF time.

I do not own this timer so I can't test ETW350 like I've tested other timers.
I think the way this timer works, is program1 is ON.
And program2 is OFF.
Again, manual is not CLEAR about ON and OFF times.

Following instructions assume timer is wired correctly, timer is set for current time, and you want to set 'timer' function and not 'random' function.
Here's how to set program1.
Press arrow buttons until 1 shows in display. This is program1.
Press Set button.
Select day for program1 ON using arrow keys
Press Set button.
Select hour for program1 ON using arrow keys.
Press Set button.
Select minute for program1 ON using arrow keys.
Press Set button.
Use arrow keys until 2 appears on display. This is program2.
I believe program2 is for OFF times.
Set program2 using same steps above.
Be careful to match ON and OFF days ... for example ON 7pm Monday and OFF 9pm Friday will keep lights on from Mon through FRI.
Conflicts in programming will cause timer not to work. For example program1 ON 7pm Monday, program2 OFF 9pm Monday ... but programs3-4 say opposite times.
Make a schedule of program times before starting to avoid conflicts.
Try steps above and test fire that timer, and then add a comment.
