I would like a bit more flexibility in programming. The limits on changes per day and weekday and weekends being all the same are limiting. I like the remote access via wifi.
Wireless thermostat came with new A/C installed by contractor. Really like it. It is at a weekly beach rental property and I can follow the use of the a/c from the tenants.
I am an HVAC contractor and installed a T6 in my own home. Tstat is pretty good however the geo zoning is a bit unreliable. Also the ambient sensing bulb seems to be poorly calibrated and is so sensitive.
