RE: Re: Controlling Heating

Stuart,

One general question:

If I want to control central heating in each room individually, each radiator has to have some kind of valve which is operated remotely.

I asume that they will need power, so each radiator will need two cables, one for power and one for control signal.

Is there any way to reduce that cabling, so we don't need to rewire house?

Also, putting power socket into bathroom is against regulations, I think.

Nik

Hi Marc,

I just got my connection back after a month, and I was scanning the
stuff I missed, and I noticed no-one replied to your mail, that's
the problem on a list where the signal to noise ratio is so low.

Anyway ... I beleive what you want to do is use a Universal Module
(http://www.laser.com/?laserlink=SGUM506) unit to drive a larger
relay to do the switching.

I know there are a couple of people use this or a similar method,
and Keith D should be able to give you more precise advice.

Also, have a look at "How do I automate...." in the FAQ, there's a
link on there to Keiths site and info on how he did something
similar.

a Dallas temp. sensor and would like to control the connection which

rated at xVDC. Am I thinking the wrong way 'round, am I stupid or do
I have to do something totally different???
