Worst people ever!
I bought 2 units to upgrade my old thermostat. They were defective units, they would not connect to wifi which is why the whole reason for me purchasing them in the first place. I contacted customer support and we tried troubleshooting every way possible and still would not work. I return them and I lose $140 restocking fee. Punch of crooks. DEFINITELY DON'T RECOMMEND!!! ... show more

Expensive but required for my new system.
It works well most of the time. However I do have to reset it every few weeks. It is quite expensive but required for my new system.

Sorry, Amazon- 0 for 2
Delivered in a plastic pillow pack (this is on Amazon) and the unit carton it was packed in was damaged and filthy (this is on Seller). I suspect it was used. It works, but had to be reset by the tech who installed it. Sorry, Amazon 0 for 2 on this purchase. For a $270 T'stat, disappointing.

Smart thermostat, definitely not a Nest
First thing: This thermostat will only work with a Rheem Econet water heater or HVAC unit. The good: Nice looking unit, and so far (2 days in) it works like it should. It was easy to hook up to my wifi, but you need to have the app loaded on your phone before you start. It was easy to program with a schedule, you enter one day and then copy it to however many other days you like. I'm retired, so my schedule is easy. After you hook it to wifi, you can get weather reports from the thermostat, that's pretty cool. It can be set to pretty any way you want the attached device to work. I got a heat pump with strip heat, and as it came out of the box it was set to call for strip heat if there was a 2 degree difference in the outside temp and the set point. I set the strips to lockout above 20 degrees F, and will experiment to find the best setting for that. Another cool feature is that you can get a lot of system info from this. It tells you how the actual units are running and if there are any alerts on them. The bad: The app is pretty well useless if you're used to a Nest. It allows you to set the temp and Home/Away status, that's pretty much it. None of the diagnostic/status info is available through the app. You also have to drill down through the app to see if the unit is actually running. I think this is because Rheem water heaters can use this also, and all equipment is listed on the main page, so you have to pick one to get info on it. The Home/Away status is not automatic like it is on the Nest, you have to manually tell it you are home or gone. I have left the house a couple of times already without thinking about it and had to set it from the app (if I remembered to). It also does not tell you how much your unit runs each day. This is pretty handy to have if your electric utility lets you monitor your KWH usage like mine does. All in all, it is a very nice looking unit that is definitely not in the same league as the Nest. The newer Rheem units can be wired for the Nest, but I didn't find that out until mine was installed, so I'm going to see how this does for a while and see if Rheem updates the software for it to add features. Update 5/1/19 I raised my review to 4 stars after using the EcoNet thermostat for a while. The thermostat itself works very well. The app on the other hand is even more useless than I thought. It appears that the server running the backend of the app is either very busy or down a lot. I can click on the app and wait for several minutes for the app to update. I am sure that my internet connection is good because all my other apps work at the same time that this one is sitting there looking at me. Rheem needs to get their act together on this if they use it as a selling point. ... show more

I (stupidly) ended up with this thermostat as part of my new Ruud furnace and A/C system. In my opinion, this thermostat needs a software overhaul before any more units are sold. I tried to have it removed and my 7-day programmable Honeywell put back in, but that is impossible because this thing is integral to the Ruud system I purchased. In the summer, I wanted to have the fan run continuously even when the compressor was off to keep the air circulating in my house, as recommended by the installer. The techs from the company that sold and installed the unit made multiple trips to my house and multiple calls to somebody at Rudd/ EcoNet trying to switch it to continuous fan, but despite everyone's efforts, after a few hours the fan would shut off. The techs didn't know how to do it, and the instructions from Rudd/EcoNet did not work. No matter what they did, the fan would not stay on. After a lot of angst and phone calls and visits, someone ended up changing the schedule - the 28 time periods in the week - to continuous fan. They didn't explain that to me, but it was fixed and it was good for the summer. Then autumn came, I switched over to heat and didn't want the continuous fan. So again, I started down the road of trying to do it myself and failing and then calling the installer. I spoke with the tech supervisor. He gave me the wrong information about how to change the fan setting, and the fan reverted to continuous on. I eventually figured it out on my own: the system will only override its schedule for a max of 8 hours. Any change you make will not hold beyond that time. So in order to stop the continuous fan, I had to change the fan within the schedule. But there is nothing in the 34 page on-line instruction manual that explains that. And now twice a year, I will need to adjust 28 settings (7 days a week, 4 schedules a day) to turn on or off the continuous fan. My sister is coming to visit and I will need to raise the heat significantly while she is here for a few days. There is no way to do this beyond the 8 hours. On my Honeywell, all I had to do was press a HOLD button and it was done and would stay at that temp until I wanted it to return to the schedule. I am also noticing that one corner of the touchscreen doesn't work well - the lower right quadrant will not always respond to the finger touch. Sometimes I have to touch it multiple times to effect a change. And a couple of times I have had to stop and come back later because it was not responding. What most irks me most is that I am stuck with this thermostat. I can't switch to something better or cheaper and easier. And I, the consumer, have no way to contact Rudd directly. Rudd/EcoNet doesn't have any contact point for consumers. They instruct you to contact the installer. But the truth is, the HVAC companies and their techs are not thermostat programmers. ... show more

The dumbest "smart" thermostat ever
We just recently replaced an almost 30 year old furnace with a new energy-efficient model. The contractor told us we had to also upgrade the thermostat and installed this thermostat. My biggest beef is that you cannot change the temp and "hold" at that temp until the next schedule change which my previous dumb/smart thermostat was perfectly capable of doing. So, if your program is to keep the house at a low temp during the day during the work week, but you are actually in the house at that scheduled "low temp" time, you have to keep telling the dumb thing to not go back to the schedule. Someone else claimed that it would "hold" for 8 hours -- mine "holds" for around 2 hours. The "manual" is a joke -- it gives you labels for the icons, but that is about it. The WiFi connection seems dumb too -- I tried warming up the house from the road as we were on our way back from vacation, but it didn't change what was happening in the house. It will tell you the outside temp, but if you have a smartphone or can step outside, why do you need that? I wish I had my old 30 y/o thermostat back. :( ... show more
