It may be your location for the photo cell. There is a cover on the cell in most cases that slides up and down to let in light. Or you may try turning it in a little different direction to get more light.

Where can I get additional push pins?? Also disappointed that the Intermatic timer 1101 stopped working 13 months after it was purchased. Just 1 month over warranty. Should last longer than the 4 months...


Yeah, I have seen tons of these units fail early. Usually someone stripped the gears.
Another approach, in terms of lighting control, is use dusk to dawn or timed motion sensors. They are always "on time" where the clock needs to be changed many times over the course of season changes, etc. They do not need to be reset after power failure or daylight savings, they just always work/
In a commercial building, interior lights should be on 24/7 OR motion sensors, and external lights Dusk to dawn.
In residential, motion with duration timer systems seem to work the best. Replace the Intermatic. Even the digital Intermatic requires user intervention all the time.

Can I use outdoor timer indoors.Its a dusk to dawn timer but no lights will be on


If outdoor timer is programmable, and does not turn ON automatically at dusk, then timer can be used indoors.
If outdoor timer is activated by photo eye, and turns ON automatically at dusk, then it cannot be used indoors, because the timer turns ON when it senses darkness.

Outdoor lights timer: Intermatic HB851 photo timer with dial. How do I set it for dusk ON then off in 8 hrs.


Intermatic make HB51 timer.

If this is not your timer, then add a comment.
To set for ON at dusk, and off 8 hours later, rotate dial to the number 8.
Timer turns on automatically at dusk.
Timer set to 8 hours will start countdown when timer turns ON > and 8 hours later timer will turn off.

Make sure timer is turned away from lights so photo-eye doesn't receive feedback.
Feedback is when the photo eye gets too much light, and then timer thinks it's dawn, so lights turn off, and a moment later photo eye thinks it's dusk again and lights turn on again.
Feedback from lights will cause timer to reset the 8 hour countdown.
A car pulling in the driveway can cause feedback.
If the timer resets because of feedback, it begins the 8 hour countdown again, so the lights will not turn off until dawn.

You can test timer by putting black tape over photo eye, and then timer will turn on.
Set timer for 2 hours for example and then check if timer turned off 2 hours later.

If timer is not functioning correctly, then timer is defective.

How do I get it to start at dusk and run for 4 hours


You posted under Intermatic make HB51 timer.

If this is not your timer, then add a comment.

To set for ON at dusk, and off 4 hours later, rotate dial to the number 4.
Timer turns on automatically at dusk because timer has photo eye.
Timer set to 4 hours will start countdown when timer turns ON > and 4 hours later timer will turn off.

Make sure timer is turned away from lights so photo-eye doesn't receive feedback.
Feedback is when the photo eye gets too much light, and then timer thinks it's dawn, so lights turn off, and a moment later photo eye thinks it's dusk again and lights turn on.
Feedback from lights will cause timer to reset the 4 hour countdown.
A car pulling in driveway can cause feedback.
If timer resets because of feedback, it begins 4 hour countdown again, so lights will not turn off until much later than planned, or not turn off until dusk.

You can test timer by putting black tape over photo eye, and then timer will turn on.
Set timer for 2 hours for example and then check if timer turned off 2 hours later.

If timer is not functioning correctly, then timer is defective.

How do I set it and can I use it indoors?


I see nothing in the manual that says 'outdoor use only' EXCEPT timer runs on photoelectric eye.
Timer turns ON automatically at dusk, so if timer is inside, and indoor lights are ON, then timer stays OFF.

To use timer outdoors.
Plug timer into wall.

Rotate dial to set how long timer will stay ON.
Set timer to turn OFF 2 4 6 8 Hours after dusk
Set timer to turn off at dawn
