Question about Fans
Here is the situation:
There's a switch on the wall that turns on the bathroom light, and also turns on the extractor fan (at least it did before the fan broke).
The wiring that comes through the ceiling to connect to the fan consists of two grey wires, each containing one red and one black wire. In one of the grey wires the black wire is cut back, in the other, the red is cut back...
There is also a third wire, a black cable, all on its own.
On the circuit board of the fan there are three places for the wires to connect, labled, 'LS' 'N' and 'L'
My first question is to ask whether someone can tell me which of the wires I have described match which of these letters.
My second question relates to two wiring options which the instructions suggest.
The fan is fitted with a humidistat for automatic control, with the option of manual overide from the fitted pull cord or remote switch.
Option 1 is for wiring the product for manual overide using the internal pull cord.
Option 2 is for wiring with a remote switch.
Does my situation count as having a 'remote switch' - the one that also turns on the light?
My preference is that the fan does not automatically turn on (manual overide) when the lightswitch is turned on...
What do you advise that I do?
I would be most grateful for any help that you can offer.
is the fan working correctly, if it is not it could be a bad armature or field

yes, if the three switches are all made together, then there is only one feed. sounds like a bad switch, or possibly bad exhaust fan. check voltage at fan with switch on, if not qualified, be careful, or call an electrician

SOURCE: Every winter water drips from
condensation is created by 2 exteme temperature change.
looks like the loft space is colder than the rest of the house.
first make sure there is not blockage in the vent. then warp the vent with fiberglass as much as you can. it doesn't matter what R value the fiberglass is. just enough to cut the temperture change.
you still going to need a exhust fan in the bathroom.

If you don't want the to use the remote you don't have to, but you don't have enough wires to switch the upper light, the lower light, and the fan. You can, however, switch the upper and lower lights together if that's okay. In order to do that you'd connect the white from the ceiling box to the white (neutral) on the fan, then the green from the ceiling box to any green(ground) wires on the fan, then the black from the ceiling box to the black(motor) from the fan, then the red from the ceiling box to the blue and orange (lights) from the fan. I'm assuming that the black and red in the ceiling box are also in the switch box where the fan/light control switch is going. Those are the ones you'll connect to the controller.

that is strange
normally a 3 wire switch could only be able to control 2 things + off. black would be common, red would be one fan speed or set of lights and blue would be the other fan speed or set of lights.
if it is a replacement, couldn't you just hook it up like the switch you are removing?
most likely the black wires are grounds for everything and white would be power. hook it up however you like. white power would hook up to the black wire on the switch and then the blue to one light and red to the other set of lights white wires.
