Cool to see other guys thinking about tackling this item too. I'm interested to see what you come up with.

I'm working on a similar project to control the GSHP I assembled this summer. I just posted some (admittedly sloppy) Arduino code that I'm using for datalogging the DS18B20's. It's a little bloated for the 328P chip, but runs fine on chips with more memory.

The direct control of the GSHP is working now using two OMRON ZEN PLC units with some thermister / voltage divider circuits. I plan to indirectly control everything with a Raspberry Pi / Raspian / Apache web server.

Have you considered using a tablet or cheap smart phone with Android or Linux and a custom UI as a thermostat interface? I am considering something in that direction.
