Input:
Question: What is the size?  The size listed in the description doesn't seem plausible.  It shows 11" long by 8" high.  That's bigger than any tablet computer.
Document: looks good and works if you dont mind temp swings of up to 8 degrees up and down.changed the swing settings and reset ,still varies room temp the 8 degrees from temp set
Not the highest-tech thermostat by a long shot, but it does the job and includes well-written instructions. Last time I had one installed by a retailer I ended up paying over $300!
I have not seen the display of 79 actually change. Whether this recycling sooner than my experience with prior devices which would cool down two degrees below that set and turn on when the temp reached one degree above that set may cause excessive wear and tear on a system and whether this would use more electricity in the long run verse a thermostat which caused a system to stay on longer is a real concern of mine.
My furnace would run, and run, and run and never stay off for more than 5-10 seconds for, well... I don't want to even say how long,  when it finally occurred to me that perhaps there was something wrong with the thermostat controlling it. So,  I read several reviews on different digital thermostats and settled on this one. SO glad I did! Simple to install,  took me maybe 10 minutes (and I'm just a girl who's dad taught her basic wiring skills).
My five star rating assumes the thermostat will have a long functional life (10+ years). If it fails prematurely, I would drop my rating to the minimum "1". (I think all mechanical/electrical devices sold should be designed for a minimum 10 year life).My previous thermostat was a fancier programmable type; it lasted 13+ years before it started acting up. Turns out I never used the programmable features, one reason being the internal clock didn't keep good time.
It also has the backlight (when a button is pushed) that is great when the room is dark. I would have preferred to have it display both ambient and set temps., simultaneously, but that's not essential. Note: the instructions say the "heat" or "cool" mode will be shown on the display; MINE DOESN'T.Replaceable Face. The electrical works are in the face part, with pin connections to the wall mounted back-plate wiring terminals when the face is "snapped" on.
used 2 on an old electric dual unit and newer gas duel both work fine,battery sounds to be the thing to watch for if indicator is slow to detectand systems dont operate correctly due to the slow WEAK BATTERYindicator on the screen
simple and right to the point and easy to install, an idiot like me can do it.a nice, cheap upgrade
nice stat no c wire need  no hassle of set back  great cust service they return calls very fast and are knowledgible
love the blue light on the screen. installation was a breeze. so much easier to use since the controls are on the face rather than on the bottom. worth every penny
Answer: no
