I have a 3 way vacancy sensor installed (MS-VPS5MH-WH). It’s works perfectly in test mode, but once it exits test mode it doesn’t react to motion. The button and companion switch work to switch the lights on or off but not motion detection. It auto switches off after programmed time.
I assume it’s in manual-on and auto-off mode, but I can’t seem to change the sensing mode. I am holding down the smal button on the left side but nothing happens. I am able to change the delay by holding down the main button with no issues. It’s almost like the little button doesn’t work, but this is the second one I’ve had (on same circuit as I returned the other one) that has the same issue.
Any ideas? Am I not entering sensor settings mode correctly? Do you not do that by holding down the small button?
