My heating is in place, but most of the pipe work is accessible. The current heating system replaced the original hot air system. Since then, I have replaced the boiler with a combi system. As the central heating system was installed after the property was built, I may run into problems zoning off 1st and 2nd floors. Basically the radiator pipes run upstairs, service upstairs, then run back downstairs. All this pipe work is in 15mm pipe.
I can script a windows system or even write an HTA using VBScript. I understand the majority of VB.NET, C# or even Java. I get a little lost in the OOP side of things. Something I have wanted to do for a long time is write a programme to control a system. I was thinking with starting off with a basic VB program to interface with a motor. lol. I bought a text book and all the bits on the subject a while back but its still in the book shelf :-(. I had a look through their protocol. At the moment it is all double-dutch, so it'll be a steep learning curve.
I am certainly happy to get my hands dirty; just not sure where to start.
Regarding Heatmiser, I think I have worked out what bits I need with some help from Heatmiser. I don't seem to be able to get a definitive answer from them whether I can connect the JARA or the network interfaces to the UH1 wiring centre. Maybe someone can look over the UH1 wiring diagram and confirm? http://www.heatmiser.co.uk/support/admin/attachments/merged_uh1_diagrams.pdf
I've put together a graphical schematic, (link below) detailing the components and their location. I have run Cat5e cable all over the house, so using their 12 volt system should be possible.https://picasaweb.google.com/lh/photo/93XcUr2I99c-6pPImLHYuQ?feat=directlink
Nice find on the Google code page. From what I've read, it seems the PC control systems daisy chains the thermostats together, rather than connecting into the UH1, which is what I want. The developer uses the word 'chain', reinforcing this. I did a 'hello world' Perl script several years back, but that's about as far as I went. So how to get it to work with LMCE, I have know idea.
I might purchase the Heatmiser thermostats and the UH1 which is the important first step then move on when I find out more.
