Blue Fan w/ Panasonic Whisper Bathroom Fan

That’s actually what I was wondering myself.

It wouldn’t surprise me, similar to how dimmers and switches leak enough current that some LED lights stay on even with the switch off.

The difference there is those don’t usually have a neutral. The leakage is too power the dimmer. Here in theory it has a neutral. Although it can operate without it, so it must have circuitry like that.

@EricM_Inovelli or @Eric_Inovelli Now that we’ve got specific steps to reproduce, can you share this with the manufacturer? I’d also be happy to join your Teams or whatever other chat to provide additional troubleshooting.

It can happen with a neutral, the internal hardware doesn’t change when you connect a neutral. I’d suspect there is protection across the switching devices that includes a capacitor and that leaks current.

Any prospect on getting this fixed? I think I might just have to replace mine with an old LZW30 I’ve got lying around.

+1.

I have three fans running Red 2-in-1 (as switch only, not as dimmers) and they worked fine for hours (I typically have them on 7200s timeout so I only ever turn them on).

I’m currently running them on 2-in-1 blues.

Just finding this thread as I have a couple of Panasonic Whispergreen fans installed as part of a bathroom remodel. Was this just forgotten/ignored?

Not forgotten, just unsolvable. The zephyr switches don’t work with whispergreens. Despite the original warnings I am using Reds - not for adjusting speed, but just for automatic on/off and to blend with the rest of the switches in the cluster.
