I've started a similar project and have it documented on my blog. Not anywhere near complete yet, and I welcome collaborators to bounce ideas off each other. But I do have my raspi successfully controlling my hvac system.

For a start on software, see this post:
http://makeatronics.blogspot.com/2013/04/thermostat-software.html
and a web enabled extension of this code by a fellow hacker:
https://github.com/wywin/Rubustat

For connecting your microcontroller (be it arduino or raspi) to the thermostat wiring, see this:

and this

I wish you the best of luck in your project! Hopefully you can get some good work done and share it with the rest of us :)

I have made something similar for my house, although the needs are slightly different the concept is the same. I wanted to  :-
1. measure temperature of env and rooms
2. measure Humidity
3. Control Combination of swamp coolers and Window ACs (not central ) using humidex (derived from temperature and humidity)

Did this using a combination of arduinos, nRF24L01+ transreceivers, Mango M2M software (used this for datalogging, graphical display and control). I deployed Mango on a old laptop, however, think you can very easily do that on a raspberry pi as well.

Very nice - thanks for posting. I have not heard of the mango product before but it looks the goods - going to setup the new version of it in a virtual machine now and play with it

cool, let me know vif you need any help. I will also post on control points and how calculations on raw analog (ADC) values from the arduno can be done within mango vs arduino.
it may also help to read/implement the mesh protocol for the nRf24L01+ modules. I made some modification to it to differentiate between data and command packets.

have started to put together something to get you started at http://fotohobbist.com/blog/remote-data-logging-with-arduino-bringing-it-all-together/ Note : This is still WIP, but should give you some pointers

excellent will read through once i have things running thanks.

I use all DS18B20 or DHT11 sensors so will rely on their inbuilt digital temperature numbers. I have a number of the nordic modules and have also susbscribed to the kickstarter for the new Digix product that has them onboard so i will probably use on of them as my central node. I was planning on using maniac bugs nordic libraries as they seem the most comprehensive - did you start there ?
