So I put down my money and bought a RC-2000 in black. When I pulled it out of the box I knew I made the right choice. Beautiful looking unit.
Then I tried to hook it up to my traditional single stage gas furnace. The unit would power up for 1 second, power back down, and repeat. The 24VAC power supply of my furnace could not supply enough current. I confirmed this theory with a volt meter.
So I contacted HAI technical support email. They responded with good info in a couple hours. It seems this stat draws anywhere from 15mA to 60mA depending on illumination intensity and color. I will need to get a new 24VAC supply.
I also asked about protocol information on the RC-2000. They provided the enclosed pdf document. The thermostat can not initiate communication, that was a disappointment. But it appears almost all of the graph data and other energy information can be pulled out of the ~250 accessible registers. Baud rate up to 9600 should work fine.
Enjoy!
