Question about Intermatic Outdoor Timer/Photo Control HB51RC

1 Answer

Lights continue to go off

Purchased an Intermatic Outdoor timer, model # HB51RCL. Programed it to come on at dusk and to stay on for 6 hours. However, the lights continue to go off and when that happens it then resets the timer. How do we fix the problem?

Maybe the lights are causing photoelectric eye to sense that it's no longer dark.
This is called feedback.
To check this, set timer for 2 hours.
Put black tape over photoeye.
Check if timer turns on-and-off.

If timer continues to blink, then timer is suspect. Return it for another one.
If feedback is causing the problem, then turn timer away from lights or place obstruction between timer and lights.

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 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.

I have an intermatic HB51R. when i go to program it to stay on for a certain amount of time it turns the lights off as soon as i switch it away from the on position. Am i doing something wrong?


I don't think it is supposed to be in the "on" position when setting it up.
Turn dial to "off".
Then plug timer into grounded outlet.
Turn dial to 2, 4, 6 or 8 hours to run after dusk.
Plug in your outdoor lights.
Wait until dusk.
Let us know if this works.

We need clear instructions for setting the timer


Woods makes several outdoor timers:
http://waterheatertimer.org/Woods-timers-and-manuals.html

Image that shows with this post is Woods model #49647.
Below are instructions for #49647 timer.

If your timer is different, add a comment with model number and I'll post instructions for that timer.

Woods model #49647 is outdoor timer with photoelectric control that turns timer ON at dusk.
There are 4 possible settings that show on dial.
Rotate dial to make timer selection.
OFF = timer is OFF full-time until you change dial.
ON = timer is ON full-time until you change dial.
Dusk-Dawn = timer turns ON at dusk and OFF at dawn
2, 4, 6, 8 hours = timer turns ON at dusk, and turns OFF 2, 4, 6, or 8 hours later.

HB51R is "on" all the time, regardless of control setting kenlarson42@hotmail.com


http://www.intermatic.com/products/timers/consumer%20outdoor%20timers/electromechanical%20timers/hb51rc.aspx

HB51 appears to be an automatic timer
Capacity is 1000Watts
Your lights are on so the circuit has power
I don't see any troubleshooting steps
It gives you a choice how many hours your lights stay on after dusk

You might try changing the selector to a different stay-on hour.
Turn timer off and unplug and then re-plug timer to see if it re-sets.

Otherwise, it looks like the photocell or 'timer brain' stopped functioning.
