Since i had one that worked (and 3 that didn't - amazon made a special case and let me return one 'one more time') I was actually able to isolate the exact problem - it's the USNAP module
I tried various combinations of my two thermostats, the modules, and location (Upstairs/Downstairs), and through the scientific method was able to determine the exact problem:
if your USNAP module says model "RTMV-01" -- 5 Stars, you are good to go, able to program schedules via your iPhone, and all the other internet goodness this was designed for.
If your USNAP module says "RTWG-01" -- 0 Stars -- quickly return this to Amazon, as it will not work. This will save you hours of resets, soft resets, secret modes, switching module sides, testing power with a voltmeter, crying softly, etc etc
To Sum up --- RTMV-01 ***** -- RTWG-01 negative infinity stars
Here are some counter points on other reviewers' feedback:
- yes, the top and bottom tabs are plastic. top is to cover the wires and bottom to cover the batteries. like all things, if you read the instructions carefully, and handle the tabs like they are supposed to be handled, they should not break easily and they did not for me.
- yes, this thermostat is screwed in to the wall, unlike some other thermostat where you have a screwed in wall plate, and then you 'pop' in the thermostat. i have one of those pop-in type at home, and the only reason they are pop-in type is because the batteries are at the back, hence you need to pop the unit out to replace batteries. for this thermostat, since the batteries are in the front covered by an easily removable tab, you don't need to take the unit off the wall to replace batteries. So having the thermostat screwed into the wall is not an issue for its design.
- i have 3 of their apps installed (iPhone/iPod touch, iPad, and Android), and they all work perfectly for me. The Android app is probably the least stable of them all, but functionally it still works. The website also works perfectly for me as well. BTW, you can provide your email on your website such that you can be alerted if your thermostat have not reported status to radiothermostat.com in 24 hours due to network issue.Read more ›
I would say if you can ensure you have the "C" wire in place or installed for you (should be cheap) and have a modern wireless router using modern encryption (WPA or WPA2), the unit should work great. As with *any* WiFi device, you can have signal problems related to distance, interference, etc... but I have had absolutely none. The thermostat runs on the 2.4GHz wireless band, so if you have a dual-band wireless router, ensure you are either using the 2.4GHz band or 2.4GHz+5.2Ghz (if your router supports simultaneous dual-band). If you're using 5GHz exclusively, the thermostat can't connect, as I learned quickly. I'm using this router: Cisco-Linksys E4200 Maximum Performance Simultaneous Dual-Band Wireless-N Router with both 2.4GHz and 5.2GHz bands enabled.
Software: I'm running the 'Thermostat for Windows' program as well as the Android app. The $10 for the 'premium' version of the Windows software was worth it for me to get the "server" features, and of course the Android app is free. I've used the website interface a couple times as well; it's decent. They release application updates frequently and keep a good change log, so I'm pleased with the level of support for the software.Read more ›
The wifi however, that's another story. It works, yes. But it was so fussy to set up. The app on the iphone kept hanging up, it seemed not to be working, restart the process. Eventually it got on the network and was able to connect. Since then it's been 99%. From anywhere I have internet access, I can see the temp in the house, and control the HVAC, it's nice. The app is free, and works, but all you get is live info, no historical, no programming, but it suits most. The computer app that you can also install also works, but you can't change anything, only monitor. From the RTOA website you can do a bit more like set up the 7 day program, easier than on the thermostat it self, too bad the local computer can't do it quite so directly. All of this depends on the internet being available, the connection the computer, thermostat and iphone all make is to RTOA's servers, not direct to each other. So if you're internet is out, even on the same network I don't believe it works (but then the remote control issue is fixed by walking to the thermostat).
Over all, for the money, it does the job. It's a relatively small premium over other 7 day programmable thermostats to get the wifi/internet control of the thermostat. What would be a nice bonus would be email alerts if the temp drops below or goes above certain values, and programming from the iphone would be a nice bonus too.
Update: The thermostat has been 100% trouble free, the app has gotten better with in app programming, widgets and other niceties. I upped my rating to 5 star, for the $99 price tag, free app and web interface, it's hard to give it anything except 5 stars. While set up was a bit tedious, it did work.

Works well, though I have not yet hooked up the wireless part. Note: I use it for a hydronic (infloor) heating system. It matches my other CT-30 units in the house.Published 9 months ago by jtflag
