No, you're wrong again. A complete lack of fact there. Well done,
you've just highlighted your own ignorance and lack of metacognition.

Here we go again: somebody apparently making back-to-back posts in a thread
on his own. Those of us with killfiles are only aware of Jamie when people
start quoting him. It was noticed something like two years ago by several
people that he was showing the symptoms of a personality disorder, so
there's no point trying to converse with him, because you'll not get
anything sensible. And from what I see of the few quotes, now, he's become
foul-mouthed like a burst sewer, so I'm happy to note that most of his
process of deterioration has been hidden from me. Killfiles are good.

I presume Graham is referring to the little tiny heater element they
sometimes put inside thermostats, which of course requires a neutral line
to operate. It heats up in tandem with the radiators (or whatever heating
technology is fitted).
Afaik the idea behind this device is that if your thermostat is in a
particularly cold part of the house, its ability to regulate the
temperature might be compromised if relying upon nothing more than ambient
temperature.

That would just turn the thermostat into a simmerstat, as used to control
the boiling rings on an electric cooker. Not really a thermostat then, as
its response would be (more or less) independent of the ambient temperature.

Right, fair enough, I shall stop replying to him. I was not aware that
killfiles stop ONLY the one person at a time (I don't use 'em, y'see)
I was under the delusion they blocked those particular people & direct
replies.

So, denizens of u.t.d-d Did Jamie Powell really rape a dog last week?
The rumour is out there, and Jamie has not denied it yet! Surely Jamie
Powell didn't rape a dog last week and then churlishly throw a 10
pound note at it in a self-comforting act of contempt, walking away
shouting "It was your fault anyway, Rex". Did Jamie Powell rape a dog?
Well, this surely can't be good news.

A dog can't talk, so it can't give consent. So that proves he raped
it.

Bill, I'd like to distance myself from my previously abominable
persona. I have, in the last few hours found Jesusgod and am currently
repenting for my sins. When I have fulfilled that particular
requirement, I shall move on to the evangelical phase of my
conversion, so I'll see you then. Amen.

I'm going to fit two lights in the same room. The problem is they don't
have line and neutral marked. If I get one the wrong way round will they
be in antiphase, and will this make the room get darker when I turn the
light on?

Too late for this year's Nobel's but if you can get your anti-light demo
working quickly you''ll be in with a shout for next year.

I'm pretty sure that my central heating room thermostat has a resistor,
effectively wired across the contacts. When the contacts are open,
current flows through it (into "whatever it turns on and off"), so it
acts as a local heater in side the thermostat case. In effect, it's a
combination of a thermostat and a simmerstat, and this has the effect of
reducing the 'backlash' or 'dead-zone' between the temperatures when the
contacts open, and when they and close.

I recall that, 35 years ago, the thermostat in my previous house was the
same. I believe I did do some experiments with the resistor in circuit,
and disconnected - and yes, it did influence things. Obviously, it's a
compromise between reducing the backlash to the optimum minimum, and not
having the temperature where the thermostat operates drifting up and
down.

No over-centre springs in glow-type starters........

Are you sure about that? I thought they may be dimpled to give them a
snap action (in fact I'm almost certain, otherwise they'd draw out a
long arc). The "ding" sound they make is perhaps another sign of an
over-centre snap action.

This is UK-DIY isn't it? I posted this message earlier but it didn't
appear.

Are you trying to wire up a dimmer switch?

More expensive ones have NO and NC terminals that allow you to have a dimmer
and a switch control the same light. The dimmer part is always in series
with the load, otherwise you will pop the fuse.

Well, the extreme unlikeliness of it is what made me remark on it.


Mmm. You do have a good point. Well, there's no choice: we'll have to
launch an investigation.

Is this some form of amateur Blackface routine or what?
You two are acting even dumber than usual.
