The T-6 is really easy to work with. This is the thermostat that came with the new system that was installed. It has been in for a month and I have encountered no problems.
Overall good features, similar to Nest I previously had. One problem i am having and need to call cust service is 1 of the 2 thermstats is changing temp on its own and not following schedule.
The thermostat works great. The ability to check on or adjust the temperature remotely is the clincher for me. It is a recent install on a new heating system so I can’t comment on the long term viability but don’t see any reason that it might be problematic. I have not used the geofence feature. Happy with it to this point.
