Subject: RE: [ukha_d] LD10
with
bathroom light and automatic fan
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.
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
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
:-(

bathroom light and automatic fan
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.
