Upm etw350

Copy following link to identify timer and download manual:
ETW can be used to replace 3-way switch.
3-way switching has 2 switches. Timer can replace one switch or the other switch, but not both.
The remaining 3-way switch must be rewired as shown in manual. What the remaining 3-way switch does is reverse timer programming, so programmed ON times become OFF times, and OFF times become ON times.

Want to know how to set the times "on" "off". Timer is a bit older. Front of the timer has "set' "cd" rnd."

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.

How do we set the time to stop on a UPM ETW350? I know how to set the time to start but i do not know how to set the time to stop. Thank you

In wall timers and manuals are shown on following link.

ETW350 manual:

Select from 3 different functions:
1) 24-hour Programmable
2) Countdown timer function so lights turn off after period of time
3) Random function so lights turn on randomly and house looks lived-in

I am not going to write out the steps because they show in the manual.
But a specific part of the manual might be confusing.
So add a comment and I will help until we will get the timer working.
