So far, the
RTH6580WF looks like a nice thermostat. It has all the standard 7 day programmable features plus wifi control. They also offer email alerts if your temperature gets too high/low. The only thing it doesn't have is what Honeywell calls 'advanced fan control' which is basically what you would want to run an HRV. As mentioned, this thermostat is going for $120 on amazon.

To control the thermostat remotely, you can login to a website (
mytotalconnectcomfort.com). There is no fee for this service. Alternatively you can download an app for your phone/tablet. The app is also free.
The next step up is the
RTH8580WF thermostat. It really doesn't seem to add any features besides a touchscreen display. It also only costs an additional $20 over the RTH6580WF, currently $143.50 on amazon.

To get the adfanced fan control, you have to go with
RTH9580 thermostat which costs a bit steep $240. I am not willing to pay for that, especially since I don't even have an HRV (yet).
