Hi all

I have a Honeywell T6360B room stat controlling the fan on a Myson kick
space heater.
http://www.directheatingsupplies.co....FWfLtAodNAQArw

After only a year of operation it has started buzzing for a good few
seconds on each switching operation.

The fan rating is only 3A so should be well within the capacity of the stat.

Is this just a duffer, or am I missing something?

I thought this would be the simplest most reliable solution for the
application. It seems to provide the control required, just makes a
noise doing it!

Thanks

Phil

That's exactly the same one I have for my CH, and it's never made a sound.
Take the front cover off and have a look inside, maybe there's a wire arcing
or something else untoward going on.
Turn the stat down first, then when it's exposed, create demand and see
what's happening.

There isn't anything in those that can buzz apart from the contacts
arcing, and I imagine that is what's happening.

The contacts might have a tiny magnet incorporated to make the action
more positive.

You may be able to clean and re-tension the contacts.

If its bimetal, check thermostat contacts & cable screws.

And the heating element wound around the bi-metal strip.

Never really understood why they have a heating element ? ..... do you
know why.
Sort of expected Bimetallic strip would simply respond to the air temp,
so why does it need heating ?

It essentially radically reduces the dead zone.

See above.
