When I was converting my old HVAC system from full line voltage to low-voltage digital controls, I bought this thermostat to control the relays I used for the conversion. One of the features I like most is the adjustable "span" that controls the temperature differential between shut-off and turn-on. During moderate weather, you can adjust the span to 1 and the set temperature can be maintained very closely without putting an undue burden on the system. During more extreme weather, you can set the span as high as 3 degrees for wider temperature swings, to avoid the short-cycling that can reduce the life of your HVAC system. Many thermostats don't have this feature.

Another feature I like is the blue backlight, which also stops working when the batteries are low to conserve power. And speaking of batteries, I like that it uses AA instead of shorter-life AAA, and I don't have to disassemble anything to replace them because they're right behind a door that swings open from the front.

The one design feature I find somewhat odd is the fact that they located the filter replacement reminder reset button so prominently (the small button) on the front, instead of behind the door, but the good news is that resetting the reminder requires pressing and holding the button for 3 seconds to prevent resetting it accidentally.

Finally, I'll mention the main reason I was looking for a thermostat in the first place. I already had a Honeywell thermostat that I had bought for my low-voltage conversion, but in testing it I discovered that it was just too sensitive to transitory temperature variations, such as even minor handling of the thermostat case itself.

Unbelievably fast delivery. Used to replace the unit I had for 4 years. Unit snapped on and off and worked great.

Simple and easy to use, easy to install, can't go wrong. I know, I know, everyone else is using smart thermostats. Well I work from home and an always home, so I don't need a smart one, this one works and works well.
