This thermostat was very easy to install with good instructions. It is much more responsive than the old one that was "free" from the installer. It avoids the large temperature swings I got with the old unit. It has a large easy to read display and I like the touch screen controls.
It was difficult to program. Reviewed the included manual numerous times and consulted with a handy man who did the installation until got it set right. Working well thus far and does what it is supposed to. Easy to read with large numbers but the back light display went out after a week.
