Great product!!
I used this thermostat to replace the older mechanical thermostat in our apartment. The installation itself took about 10 min and didn't need too much skill at all. I'd say anyone with just an average understanding of assembling and wiring can do the install. Have been using this product for about a week now and can say that it works great. Way better and more comfortable than the older mechanical unit and a lot more accurate. For the price i paid for this product, I'd say it's a steal. Not to mention the box even comes with the batteries needed for the unit. Overall a thumbs up for the product and 5 stars for ease of installation, ease of operation and how neat it looks installed.

Easy Install - Tight Temperature Control
I installed two of these on two different hydronic baseboard heating zones. You can tell the controller it's a hydronic radiant heating system. The controller kept the temperature on the desired setting without variation. Easy to understand instructions, well laid out.

Looks great. Easy to use and install.
Perfect for a heat only system. Used 2 of these in our home for our 2 zone heat only boiler system. Very easy install. Easy to use. Increase or decrease temp buttons only. Auto hold at chosen temp. Nonprogrammable which is ideal for heat only systems. Quick delivery in sturdy packaging. Good value for product. No defects or issues noted. Very happy with this purchase.

Installation was a breeze, but wishing for larger size wire openings.
I purchased this thermostat to replace my old analog thermostat in my RV. I wanted to be able to see exactly what temperature I was at rather than crudely guess. I installed this Honeywell thermostat in about 10 minutes without instruction. It was very easy to wire and set. I will say the only reason I didn’t give it 5 stars is because the openings for the wires were a bit small. I had to trim my large cables down to fit into the unit, not a big deal!

Easy to install and use
This replaced a mercury thermostat from the 70s for our 2 wire low voltage system with baseboard heaters. Once we figured out that we had to choose our heat source from the menu to get it to regulate the temp properly, it worked great. Looks sleek, easy to read, easy to install.

This was the second unit I received (first one was returned)- the device does NOT keep a consistent temperature. Heat runs up well past set temp. Spoke to support but they were unable to offer a remedy. Time and money wasted. Now looking for another thermostat.
