Panasonic Whisper fans (2)


As part of a dual bath remodel, the contractor added a new Panasonic Whisper Green fan in each, replacing earlier fans. His electrician did the wiring, per the Installation sketch, I blew it up, make it easier for them, and me. there are 3 switches, Light, General (the Red leads) and Fan, L-R in the sketch... Real world, his guys were kids, did the Hall bath, left, so I finished up the Master bath wiring, identical to the Hall's.

General contractor was not an electrician, but his guys were, AFAIK, I checked the wiring at the time, it was right, but now with everything finished, access to the fan end is not really possible without tearing up the ceilings.

I'm not seeing the action I expected. I have a variety of Modules, discovered there were only 3 ports available, But have yet to contact Panasonic, assuming lots of phone time.. Rather sort it out myself if possible, I've read, studied the documentation, but not seeing what the problem is.

Hall bath: Speed & Night light modules.. Not our regular usage for showers, so no Humidity. Light works, Fan goes on with the Fan switch, never shuts down until it's turned off. Not what I expected, I thought it would time out. Night Light only comes on if the Fan is On. That third switch(Red wires) does nothing to affect it.

Master Bath: Speed and Humidity modules.ight works, Fan goes on with the Fan switch, never shuts down until it's turned off. Not what I expected, I thought it would time out, or the Humidity dropped. If the Fan is On, it stays On. That third switch(Red wires) does nothing to affect it.

It's been a couple years, since late 2017 that we had this work done. A few other things, I had to do myself as the contractor, as I said, wasn't an electrician, I did a ton of wiring in my 40 years at Western Electric, it was easier for me to do a lot of it, rather than wait on his guys. I'd do a lot of extras, cleanups after hours, an advantage of being retired, I suppose, plus knowing it was done right. The remodel took out a closet to double the shower width to 5', a linear drain, added new wall mounted vanities, medicine cabinets, LED lighting besides the Panasonic Fan, all Moen, Koehler, top end fixtures, as well as all new tiled floors, tub & shower the tile goes to the ceiling, nicely done, master bath had to have a pocket door, contractor used a cheap set of track & rollers, I replaced it with Johnston, soft open/close hardware. then had painters in to texture, paint as needed.

So the Panasonic fans are my one remaining unresolved problem. We use it as it is, manually handling the fans, I think I have Motion module for both, but am not wanting to confuse the issue.

So any magical ideas, documents?

I have none...

Re: Panasonic Whisper fans (2)


What model do you have. There are a few confusing details there.

Re: Panasonic Whisper fans (2)


The Note in this Service Manual Wiring Sketch is confusing to me, calls the Red wire switch a "Hi/Low Switch: When plug-in Multi-Speed Module;On/Off switch:When plug-in other Plug'N Play Modules.(non-powered control wires)".

Not the same info the various modules or Installation docs..

Maybe I'm just not seeing the big picture?

Re: Panasonic Whisper fans (2)


That is one complex system for a bathroom fan. I’ve read through the controls part of the manual a few times and am starting to get the idea how to configure the options. How is it that you’d like the two fans to work, with respect to the night light, humidity control and motion sensor modules?

If I’m interpreting the manual correctly, the reason to buy the variable speed module would be if the homeowner wanted to run the fan at low speed continually for house ventilation purposes and at higher speed for limited duration ventilation of the bathroom. If a homeowner wants to just do the latter of those two options, they don’t need the variable speed module (I think...).

Re: Panasonic Whisper fans (2)


The way I read it is the fan stays on 24/7 on the main switch and the fan goes to high speed on the red wire switch and stays high speed until you turn it down.

Yes, maybe too complex, I'll try to change the speed settings this week, and drop the timer settings, it's been a while since I stuck my head in there to see where it's at, I think I set it at the max, 150 cam, but maybe, if it's going to be on 24/7, it should be lower. If I can ever see it, the Hi/Low (Red) with make a difference, I'll know I'm on the right track. Today was the first time for me to see that second wiring diagram, but I do need to do some checking tomorrow.

On my desk I have a Multi=speed and a NiteLight module, but I have to check, see what I have up in the fan units... Pretty sure the Condensation Sensor is in the Master, along with the fan speed module Not sure of the Hall bath at the moment, other than the Night light... Motion sensor should be in the Master but... Might have unplugged it..

Really like to have it all working, but so far, as I've said, I can't see anything but just manual on/off action..

(Thanks for looking, it all helps clarify this...)

Well, if so, it should be running low, and boost on either Motion or Condensation, assuming those modules are plugged in, have never seen that, so far...

I'm still a tad confused that I can't seem to affect anything with that Red wire switch... As noted above I need to pop the cover see where what is...

At one time I was disappointed that I was limited to just to modules other that the speed/timer, but at this point I'd be happy to see either motion or condensation make a change... I can't reach it without a ladder, I did fiddle quite a bit last year, got nowhere..

(Thanks for looking!)

If you have a motion sensor, it would be in the center of the grill that has a blue light when activated.

Re: Panasonic Whisper fans (2)


Even if you’ve got other available modules, it would be simpler to diagnose operation with fewer installed. Let’s run a test on the hall bath (speed and night light modules) to see if the red wire control switch is doing anything.

1. Toggle the wall mounted control switch (red wires) and wall mounted power switches for fan and night light to “Off”.
2. Set the “Multi-Speed Air Volume” dial on the fan to something other than zero.
3. Set the “Time” dial adjacent to it to something other than zero.
4. Toggle the wall mounted power switch for the night light to “On”.
5. Toggle the wall mounted power switch for the fan to “On”. The fan should come on at low speed (if the setting in step #2 above was zero, then “low speed” would be “off”)
6. Toggle the wall mounted control switch “On”. The fan should come on at high speed for the length of time set in #3 above. The night light should operate, depending on ambient light conditions.

If it doesn’t work that way either I’ve misunderstood the instructions (which is entirely possible), the fan isn’t operating as described, or the house wiring isn’t connected as shown in the manual.

Re: Panasonic Whisper fans (2)


Tangled up with other projects, but printed it out, and will give it a shot when I finish off... I see from below I have the presence module in, but maybe unplugged, don't remember.. Need a ladder..

Re: Panasonic Whisper fans (2)


OK, had a moment to grab a ladder:

Hall Bath has: Speed/Time, Nite Lite, and Motion modules.
Master Bath has: Speed/Time, Condensation and Motion modules.

There is no separate switch for the night light, it appears to only be operated when the fan switch is On.

Motion has never functioned..

Speed/time are both off zero...

Maybe I don't have the patience, but I'm not seeing any affect of the red wire switch in either bathroom. Never have seen the Motion detection function.

Still as confusing as ever... If I can get through to Panasonic, I'll ask for a local tech guru to come out, take a look. It should be a lot simpler. I think I took photos of the wiring, back on the original installation.. But it sure looked right at the time, as I had printed, shared that Installation wiring sketch at the time. Not too complicated, really..

For now, I'm going to they gym, later ee if I get a chance to install new LED headlights in my '06 F150... The other project.

Thanks for trying...

Re: Panasonic Whisper fans (2)


Before I purge this knowledge…

If you have the fan low speed set using the rotary dial near the top end (up to 120 CFM), you’ll not be able to discern the difference between that and the fan high speed set using the three position “Pick-A-Flow” switch (110/130/150 CFM).

For the fan to turn off after a set time of running at high speed, the fan low speed rotary dial needs to be set to zero CFM.

Re: Panasonic Whisper fans (2)


Thanks Chris, naturally, I just took the ladder back out to the shop... I'll try to get in there tomorrow, drop the rotary to zero... Currently at 50 cfm, with the Air Volume 3 position switch at 150.

It's a but tough to see, but I took photos on my iPhone, so I could look without getting a kink in my neck! If I'm up close it was too close, down a step, too far away..

There seems to be a need for a setup manual, along with a troubleshooting flowchart. As I said before my contractor, and his "electricians" were not to be found when the finish items came along, I had a hit sheet, but assumed these were OK, just wanted the mess done, gone, so I didn't look too close at these fans. Until now...

At least, whoever is going on, the bathrooms are useable, h=Hall bath gets little use, occasional house guests, grandkids, but the Master is a daily shower, etc, so it was a bit dusty..

One of the demo pictures or videos shows a little green light on the Motion detector, I've never seen that, on either unit. Might be a different vintage, or could it matter which port it's plugged into? The Speed/Timer only fits in one spot, so then the choice is either of the other 2 available.. They seem to refer to the ports as being on a common bus, so I didn't think it mattered what went where..

OK, enough tonight...

Re: Panasonic Whisper fans (2)


BTW, because the model I have has the LED lamp, the motion sensor is off to the edge of the light, not centered. But unlit. Hmmm...
