At long last I got the fan (timer/humidity) running.
From previous post re electrics I got an electrician in who found the
problem was where they had taken the permanent feed from thats what
threw me.

Anyhow assuming the fan is not faulty and the elec wired properly it
doesnt turn off with the hum/timer was running for 40 minutes even after
I adjusted the timings.

I did try reversing the permanent live and switch live but that just
makes it operate on/off with the light switch. The shower room wasnt
used for over 24 hours so assuming it was not too humid.

Any other ideas to try.

Wait for the humidity to drop.

Aye but that maybe be never if the wife has a shower every morning.
Just a thought but if I taped off the part where moisture enters the
sensor (a few small holes)would that eliminate the sensor and at least
prove that is the issue?

Have you tried adjusting the sensitivity of the humidistat
There is usually an adjustment knob or screw somewhere.

Yes I have adjusted to the extremes either side for Timer & humidity.

With what you believe the unswitched and switched live swapped, did you
try altering the sensitivity of both the humidistat and the timer?

If after checking with a meter the wiring is correct, I would start
doubting the fan itself.

The sensor will be a fairly small component mounted on the PCB which is
then mounted in a plastic fan case that is not airtight. Blocking off
the holes is likely to make no difference.

In my experience the adjustments are not instantaneous.

Leave the light switch on
Set the timer for minimum and humidistat to maximum and if the fan is on
just leave it to see if if it goes off after a period of time. Leave it
for the maximum timing period.

If the fan goes off after a period of time switch the light off then on
again to see if the timer side just gives a short period of working.

With the timer still at minimum tackle the humidistat side. Adjust it
downwards in say 5% steps and wait a while after each adjustment. Find
the point at which the fan comes on and then raise the setting by say
10%. wait until the fan goes off. Close you bathroom door and generate
your shower steam.

The humidistat setting may need to be a lot higher than you think. I
have a few cheap temperature/humidity meters (£4 Ebay) around the house
they are currently showing around 68% humidity (perhaps with +/- 10%
inaccuracy).

It sounds like he needs some kind of over ride system if he is really that
worried about a low current fan running for a few minutes extra.

That sorted it I was sdjusing bot to either max or min, by setting hum
high and timer low it works perfectly...Thanks
Just need to make small adjustments now.
