need instructions for model 457864

ET8215C is Astronomic time piece that can also be programmed for specific on-off time.
http://waterheatertimer.org/pdf/Intermatic-et8015c-.pdf
1) You can disable the astronomic function by inserting a jumper shown in manual, and then program individual on-off times.
2) You can extend either DST start-time or end-time by fudging on the current time setting. For example if you want timer to turn off 1 hour after normal sunrise, then set current time 1 hour ahead. Of course this means timer turns on 1 hour later in the evening.
3) You can extend astronomic on-off times slightly by changing astro zone
4) You can set exact astro times, but the default maximum is shown as 120 minutes.

noOp is fatal failure of timer. According to what others say, battery replacement will not fix problem.
I've read people taking apart timer and adding oil to the gear ?/?, but have not done this myself and cannot say it works for sure.
Intermatic timers come with industry-standard 1 year limited warranty.
Suggest replacing with timer that operates on electric current rather than battery.

Advantage of Intermatic ST01C and EJ500 is 7-day programming -or- astro dawn-dusk function -plus- easy wiring -and- single-pole or 3-way switching. Whereas timers that work on electric current need neutral wire or ground wire to operate timer clock.

For 7-day function only, GE 15071 from Home Depot. Single pole only. Not for 3-way.

For 7-day or astro dawn-dusk, Utilitec 0192773 from Lowes. Single pole only. Not for 3-way.

For 7-day-astro-only plus 3-way switching, Aube T1034

You posted under ST01C Intermatic battery operated timer.
If you have different timer, then add a comment.

Let's review ST01C timer for a moment.
Programming will stay inside timer memory indefinitely until timer no longer works.
Even if battery is removed, programs remain. Current time setting does not remain in memory.
If battery goes dead, then current time will disappear, but programs remain forever.

If previous programming was correct, you might only need to set current time,.
In that case, you do not want to 'reset' timer and clear memory.

If you want to clear old programming entirely, then you can 'reset' timer using following instructions.
Press and hold on-off button, and then use paper clip to push in reset button for 3 seconds.
Release reset button but keep holding on-off button until INIT displays momentarily.
Release on-off button.
If display does not show, then timer battery is bad, or timer is bad.

In addition to current time, the link has ST01C manual and also has EZ to follow instructions and photos for setting on-off times (but not astro times)
http://waterheatertimer.org/ST01C-program.html

Instructions are different for astro dawn to dusk.

Keep in mind that ST01C timer has 1 year limited warranty, and your timer might be broken.

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
