Super simple unit, works well, easy hookup
Replacement for another old Honeywell. Simple hookup, screw holes even lined up so no new drilling. Working well so far.

Perfect Replacement
Need to replace thermostat and had to get the one that already had a jumper in place. This worked perfectly and compatible for my current setup. Great value.

Basic, but good.
Does exactly what it looks like. Nothing g more, nothing less. Temp up or down with one tap to display, second to adjust. One star off for not being back-lit. Hard to see.

Stay cool with Honeywell.
Very simple to install and use, I have been using this for a year and recently purchased another because I have 2 units and I preferred that they match.

Perfection
This is how every thermostat should be. No nonsense just up and down, the way God intended. One of my favorite buys of the year.

Good product
I was very skeptical about hooking this up to our gas fireplace using only a 2 wire system but I used the white to match and black to red and it worked thanks to youtube. Easy install and does the job. Only wish it had a Celsius option.

Works with 12V DC , 24VAC not required. 2 aaa cells = 1 year
Just installed.Simple, works. (not long term comments) Controls D5 Espar Diesel hydronic , only connected Espar Red and Yellow ( of R + Y +Brown cable on NA version Espar). R to R(+Rc) , Y to W. Is Extremely basic, only has one temperature setting that you can change just by pressing the up down arrows to new setting. ( Can be set to F or C). Unit is surface mount , wires enter through back (drill small hole in wall). Only negative is it only goes down to 40F (4.5C) . May ? want to set just above freezing, or maybe 4.5 is OK.

Easy to operate.
Easy to install and simple to operate. If we want it cooler if we leave for a few days we just push the down button until the desired temp shows up and walk away . We can turn it back up when we get home. No worries about programming it wrong like the programable thermostat we did have before.
