Re: Replacing and automating the Central Heating switch (PIC fixed)

["Frank Mc Alinden" <frankmc@xxxxxxxxxxxxxxxx>]

Hi Gareth

Have a look at the link it may help....

http://www.automated1.com/prod_atp1000.htm

I have one of these in bits ,it was given to me to test and was going to be
used with a comfort i believe.....The actual sensor inside is an
LM34...Which from memory  is a Farenheit sensor im sure you can get a
Celcius sensor...there doesnt appear to be anything else on the board
except
a track which appears to form an inductor , so maybe you can make your own
sensor....
This sensor changes 10mV per degree F
HTH
Frank
