H725 5/1/1 Day Programmable Heat Pump Thermostat, 2 Heat/1 Cool DIY Instal, with 4.5 sq. Inch Display

Omg this thermometer has different settings that you can preset for different days and it remembers them and holds the temperature for what you set it for for that day. This is a great game changer.

I replaced a Bryant thermostat that was very easy to leave on EHEAT mode because of the small interface screen. After one too many months of unnecessarily high utility bills I decided to change thermostats. The wiring was pretty much the same, but I had a question about where two wires went. Through careful rereading of the instructions, and reading the installation instructions for the original Bryant unit, I made an educated guess that worked the first time. On these types of projects, learning a bit about the nomenclature makes a difference.

So, I had an Ecobee, and although, I reached out to their support several times, and they told me their thermostat is compatible with a 2H/1C system it just never worked right. I decided to get a system specific for 2H/1C and it worked. I was a bit confused about the instructions, if I am being honest and there is a section where it read you'd need a jumper if you have a specific system, but in the end I was able to get heat and cool to work. The unit lights up when you press a button, and it's easy to read as shown in the picture. I will update my review after having it for a while but for the price it's pretty hard to beat, IMO.

After returning home to a cold house from a long trip, I found that our very expensive touchscreen wi-fi thermostat wasn't working. I needed to get something quickly in order to get the heat turned on, so I ordered this unit with next day delivery.Installation was simple using the included printed instructions. We have a Carrier heat pump with emergency heat, and this thermostat worked perfectly. When installing this for a heat pump, you'll need to know whether your reversing valve is energized during heating or cooling. Most are energized during cooling, but you can easily find this information by googling this for your particular heat pump brand. Once you have this information, you connect the reversing valve wire to either the O (for cooling) or B (for heating) terminal on the thermostat. This sounds more complicated than it really is.I didn't use any of the programmable features, as this was just a temporary fix until I can get a replacement OEM thermostat, so I can't speak to the ease of programming, but for setting simple heat/cool temperatures, it was very easy to use. This programmable unit was only a couple of dollars more than the non-programmable version, so I got this one in case I need to use it again longer-term.

If you don't want or need a "smart" thermostat but want programmable settings to fit your lifestyle and cut heating bills, this is the ticket. It has a large, easy to read display, and compared to other programmable thermostats I've used over the decades, this is quite easy to program and change. Be warned, installation could present challenges, such as, slightly different spacing of mounting screws from your old thermostat. Oddly, the simplest legacy connection, a two wire red-and-white heat-only setup (wires labeled R or RH and W) turned out to be a major headache. The setup is not covered in the Installation Manual, but the logical guess is to connect to the RH and W/E terminals. Didn't work. After debugging that everything else was working, I posted a question on Amazon. Within hours, the seller responded: "you need to connect RH- W2 to realize the traditional thermal mode." Too bad they couldn't have just included this in the manual, considering how common this arrangement is in older homes. But kudos to the seller for the quick and correct answer. Good thermostat, good value, good customer support. Recommended.

Used re replace old thermostat, 24V simple 2-wire red-white wiring. Works beautifully, easy to program

This thing is junk. I’m a pretty hand guy and installing a thermostat isn’t a struggle for me. Until I bought this one. It is wired wrong from the factory. Turn on the heater and the ac turns on. Turn on the ac and nothing works. Sat on the phone with an hvac technician for over an hour trying to get this to work. It’s going back asap.

I like that it lights up because my old one didn't. The down side is that the up and down buttons get stuck sometimes and the temperature after you set it and walk away can keep going up on its own. I just have to make such the buttons pop back out after I press them. Other than that seems to work fine.
