need instructions for model 457864

The Utilitec 0192773 timer has astro dusk-to-dawn functions.

The manual is very unclear at the exact point you need it to say how to set dusk-to-dawn.

The following page has the manual, with explanation how to find the astro dawn-to-dusk setting
http://waterheatertimer.org/Program-wire-Utilitec-0192773.html

When you are programming the timer, press TIME button and hours start flashing.
Press the +/- button ... the trick is to keep pushing the +/- button until it finally gets to astro, and the sun-moon symbol shows on display.
When the sun-moon symbol shows, the display also shows AM.
Press the +/- again and PM show.

So if you want Program1 to turn lights ON at dusk (PM), then your display needs to show: 1 ON PM sun-moon.
To continue setting astro, do not set hours, just press PROG button.
Then repeat the steps above until: 1 OFF AM sun-moon show on display.

This manual is a bit confusing because it jumps across steps without telling you.

Look at manual instructions above Fig 11 where it says "Programming ON/OFF event times without astro." This is where your instructions are.

But let's start back at Fig 6. Setting DST
I think the instructions jump from DST at Fig 6 to programming at Fig 11

DST says:
If you want timer to compensate for DST, the display automatically defaults to AUTO.
If you do not want DST, press SET+ or ENTER/NEXT and display reads MANUAL
Then it says: Press MODE+ to go set up ASTRO feature

But you don't want ASTRO

I think this is where you by-pass ASTRO completely by pressing MODE+ until the screen looks like Fig 11 below:


Now you are at programming steps to right of Fig 11:
EVENT1 shows in screen
-Press Day to set days > you keep pressing Day to show M-F, Sat-Sun, or individual days
Then use SET+ and SET- to set ON time for EVENT1

Press ENTER/NEXT to go to EVENT2
EVENT2 is OFF time for EVENT1

Tip: Other intermatic timers ignore all Events that conflict ... so you might make on-off chart before programming

After EVENTs are programmed, press MODE+ to go to AUTO
