The instructions say that it takes 30 seconds for the sensor to activate. Is this true? If it is true, my unit is defective. Thank you.

I have never timed how long it takes, but like any photo cell it's going to take up to a few minutes sometimes. This all depends on the location, etc. I love mine! It's been the best one I have ever bought.

If you are referring to the LDR sensing whether it is dark or light and in turn activating the switch; there is a delay of a few seconds before you would see the lights turn on or off. If the light sensor has already been chosen as your method of activation then you wouldn't know when it sensed the change in light - therefore you wouldn't notice the delay. Hope this helps

I had my mechanic diagnose which sensor was defective. Replaced it with the one from Amazon. Still not working. Mechanic checked the new sensor and it is defective. I'm stuck with a paperweight.

Remember this is dusk to dawn light.. the light will not trigger ON during the day but Its on nite time if the sensor is triggered.. Hook it up to ON and OFF switch, turn on the switch and leave it ON..

The customer service rep said you have to remove the battery, turn unit off and let it sit for a while. ( about 5-10 min) it should turn on after that.With that said, I followed the directions perfectly only to come to the conclusion I had a faulty unit.

I believe that the way this one works is by sensing the presence of the minute electrical current or the lack thereof. The sensor must be set so that the pump runs at least 10 seconds. I am assuming that is enough time for the pump to discharge enough water and lower the level of the water in the pump sufficiently to allow the sensor to /not/ sense a current and therefore stop activating.

I have had a similar experience with one I bought for my son. It seems the sensor gives out too quickly.

My dogs trigger the sensor when they walk by the bathroom in the hallway. I have the unit set to run for at least 30 seconds when it senses motion. It turns on when anyone walks past the bathroom.

Hard to say without seeing it. Double check your wiring and your settings. It could be a loose wire, for example, or maybe the sensitivity is turned up too high. I set up the sensitivity on mine to come on right as you walk through the door. Also, if you have the time turned all the way down (test position), it will stay on for like 30 seconds and then shut off. That's the shortest setting. If it's coming on and off in shorter intervals than that, there is likely an issue with how it was connected.

It is important to adjust the sensitivity on the unit. I would turn the adjustment until it alarms and then back off about half turn. That way it is pretty sensitive.

As others have mentioned, check to see that the unit is not set to manually on, if it is not then you probably are experiencing the beginning of many problems to come with this unit. I returned the one I bought because of similar problems. Mine experienced problems early and multiplied with age. Read some of the reviews on Amazon. I would advise taking it back if possible. This would be a great unit if it worked properly for a reasonable amont of time.

I agree with Jose. We also bought 3 and 1 was bad. Honeywell replaced it with one that works. Looks like the magic number is a 66% rate of good sensors. Hopefully Honeywell will improve their quality control. The units that function properly work very well.

None what so ever.I stopped using it after 6 months as one sensor failed and too much hassle to get a replacement.

The sensor light does not stay on after movement or motion stops. I never timed it, but it goes off after a couple of seconds. Your batteries will last. I haven't replaced mine yet and i still give it 5 stars.

I had a sensor problem with mine at 3 months. They sent me a replacement board and was easy to install. Board was warranty and if I remember correctly they paid shipping both ways for new board and return of defective board. I was mad at first but think they handled it pretty well. No problems since at 8 months.

There should be an evident change in temperature no longer than 30 minutes after activation. Please try a higher temperature setting during the next use. If there is no change in temperature, please contact us!

place your hand under the sensor, maybe half inch away, and at the same time, hold down the "+" button for however it takes, you should hear the pump working, it might take a minute or so? (within reason) You can also go to there web site for more info. (www.simplehuman.com)

Im' not sure it was sometime ago, check to see if wiring is polarity sensitive +-, I do remember that when first connected it it took about 20 sec. to turn on the furnace, and it has to be set about 10 higher than you want the temp. Benefits of modern technology? hopes this helps
