Hi
Bazza,
I
was pondering this a few minutes ago whilst laying in the
bath.
The
fan has a permanent live feed which is used for the overrun. I believe the
timer input is only used as a trigger. I know that with my fan, it takes a
few
seconds to start as if a capacitor is being charged.
If
the light is turned on for only a few seconds it can be switched off and
the
fan will never start.
If
the light is turned off immeadiately the fan starts it will only run for a
few
seconds, and longer than this and it does its normal
setting.
Based on the above I believe the following may
happen.
1.
No enough to trigger the fan below a certain dim level.
2.
It may take longer for the fan to start and overrun may not be quite as
long.
3.
It works perfectly
I
doubt that any damage would be caused to the fan but the only way to prove
it
is to try.....at your own risk of course.
Unfortunately I cant test my theory..... I lay in the bath working
out
how I could attempt to modify the switch to provide momentary
operation.....
worked out that by removing the ceiling speaker I could place the LD10 next
to
the transformer in the ceiling void (forward planning in case of
transformer
failure).... then realised the flaw in my plan :-(
I
cant get to the junction box in the ceiling where the switch wire is fed
from.
BUGGER !!!!
The
reason for the ceiling speakers (apart from Audio in the bathroom) is that
the
bathroom is a flat roofed extension and when I fitted the low voltage
lighting
I realised thet the transformer could fail one day so it needed to be
accessable. The ceiling speakers are easily removable to gain access for
replacement. Unfortunately the junction box is screwed to a joint about 30
inches further across the ceiling :-(
Also
just disassembled the fan and greased the bearing because it was squealing.
I
would buy a new one but mine is about 15 years old and about 6" x 8". All
the
new ones are 6" square. Guess who decided it would be good to tile the wall
all the way to the ceiling :-(

Hi,
Can
anyone give me any information on which module to
use (i.e. LD10 or AD10
DIN) on a bathroom light that
is connected to an automatic fan.
I'm
not too sure if will be safe to use an LD10 with
DIM on an appliance
such
as a bathroom fan unit.
I believe the configuration is such that when
the
bathroom light is switched off, the fan runs for a
further few
minutes depending on its charge from the
during of the light being
on.
I believe this is quite common in a lot of new
houses
nowadays.
Many
thanks,
Bazza.
