I just installed one of the TC thermostats. Imagine my shock to discover that it has no "auto" mode. Do they actually expect people to manually switch between heat and cool in climates where one day can require heat and the next cool? Or both in the same day??
Nick, have you heard from the Honeywell guys if they're going to fix this glaring oversight in a firmware update? If not, I'm probably going to return it. Around here, I'd have to be manually changing it between heat and cool several times a week during the late fall/winter/early spring. Or write some convoluted script to manually change it based on outside temps.
Frustrating for a really expensive thermostat...
[EDIT] read my last post on this thread on how to enable it...
