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

["Mike Griffiths" <mike@xxxxxxxxxxxx>]

That works!

What I have done is put a relay from the Timer output to the boiler

Then I run the timer to always be on

The relay the says when it is off via in my case HomeVision



The advantage of this is I then have a test mode where the relay is
always on



So if  any one comes to fix the boiler

Put it into test mode and as far as they are concerned it is a normal
control system they are used to



I have a 12v 2 mains relay in the boiler

That way nothing control wise leaves the enclosure

Far better that running mains from the boiler to the C-bus relay and
back again

If that isn't clear give me a bell or mail

Mike
