Question: I have the fan switched on with a 30 sec timer. But the fan never stop. Whats wrong with that?
Document: We do wish there was a timer setting for 15 minutes between 10 and 20. It seems that 10 minutes isn't long enough and 20 is somewhat too long.Overall, I probably wouldn't buy this unit again. Instead I'd go with an ordinary (sensor-less) fan and install a dedicated timer switch such as the Lutron Maestro countdown electronic timer switch. We did that in a couple of our other bathrooms and we're happier with the result.
If it was a constant light that just turned on when motion is detected and turns off when the motion triggered run timer expires then it would be fine and would be great as a motion detected night light for using the bathroom at night. Instead the light does not stay on but flickers on and off as you move about and its annoying.Other than this minor annoyance, I like it enough that I am buying one for another bathroom.
If you shower before you go to work, you turn the fan off when you leave. The countdown timer runs for the allotted time and shuts itself off.
It serves no useful purpose outside of the manufacturing facility as the fan is clearly audible, so you'll know when it's on. It does however make the experience of using the bathroom at night rather like being trapped in a drive-in movie, with constant flickering of a green glow. Cover the light with duct tape and your fan is impossible to turn "on".You are far better off getting a quality fan and (separately) a manual timer to be installed at the wall switch.
)After a hot shower 3 min. would not be adequate to dry the air. That is when the humidistat takes over. It will run until the humidity drops to the range set. Mine is set to 40%. We have it in a 10' by 7' bath and the mirror never fogs. I don't see the condensation on walls either.
I've installed a half dozen different types of bathroom vent fans and most of them come off the wall of some big box store with a label that tells you how many sones represent the volume level of that particular fan. Every single one of those box store fans sounds like a freight train running through the bathroom whereas the Panasonic Whisper fans are so quiet, you have to stop and listen carefully to see if they're actually running.
I love this quiet bathroom fan with the motion and humidity sensor. Works as advertised. It was easy to install, which I did myself.
This is a great fan. I can't even hear it with the shower going. Installation was very easy. Had to enlarge the old opening about 3 inches.
I being installed many exhaust fan, but this is the best fan I installed. Easy, fast no messy and the best is the technology it has. Good for Panasonic
I purchased one several months ago to replace a 20 year old unit. It works so well I decided to replace the fan in the second bathroom.
Answer: yes
