Re: Automate my central heating - How?



 

--
Whilst timers are often built in they are a purchase option and therefore not totally integrated. It is possible t then identifiy the wires.

Ahh, but some of the timers are mounted on/in the boiler itself and could be using DCV and not the ACV from mains like my Vokera did although the timer was 240AC in that one, others are not. Just a bit of advice nearly learned the hard way J

You can of course use a relay contact in place of the thermostat/timer and avoid even having t try to figure out the internal wiring of the boiler.

 

On mine personally the heating side of the combi is controlled by a triac which has to be sufficient rating to carry the pump current. A relay would have been simpler.

Justin,

Scary stuff, I wanted to do this in my last house that had a combi,
here's the hurdles:

1. You need to find out what wiring fires the boiler on from both the
boiler stat and the room stat.

2. If it's off the internal timer, or a separate timer, you need to
isolate which wires switch the boiler stat, to bring the boiler on.

3. You need to find the *INTERNAL* switching voltage of the boiler, some
operate on 24V, some on 12V and most on 240AC.

Then you can start to figure out how or what you want to do.

I am clueless when it comes to electrics so I thought I would ask before
I
blow somthing up!

I would like t be able t control my gas combi boiler using X10 but am
not
t sure how to go about it.
The central heating works on a built in timer at the moment (not while
it's
this hot though!) but there is a thermostat in the garage (where the
boiler
is).
Would it be possible t replace this thermostat with an AD10 ? I think
the
thermostat switches 220V live though. Does that sound right?

Cheers,
Justin
