Customer Questions & Answers

My old thermostat does not have C wire

My thermostat does not have C wire, only Y, RH, W, G; can I use it with out it, my use is to control the Temp from my IPhone; please advice what I can do
Asked by: colcar2068
The "C" wire connection has to be connected to the power common at the A/C unit. If the wire isn't there you will not be able to use the radio until/unless you replace the thermostat wiring. The "C" connection is the return for the 24 volt A/C control power. Without that connection it is not possible to power the radio. If you do have an extra wire at the thermostat, but find it isn't the return (power common), someone knowledgeable will have to connect that extra wire to the common at the A/C unit. Please don't attempt that unless you know what you are doing.

Cant the thermostat be program to turn on based on an outside temperature?

Cant the thermostat be program to turn on based on an outside temperature?
Asked by: fromtheland
Unless you physically mount the thermostat outside (noting it is not designed for direct exposure to the elements), this thermostat has no secondary temperature sensor to read temperature at any location remote from where the thermostat is itself mounted. There is also no interface through the WiFi module over which it could access such local weather information via the internet (AccuWeather, etc).

if i program it form my phone would a person at the house be able to change it with out me being there

Asked by: liz
Yes, it can be locally overridden at the thermostat. However, it appears that at the next time a scheduled change point is reached in your pre-set program, the thermostat will revert back to the scheduled times and associated temperatures. Also note that overriding the fan switch manually on the left side of the thermostat will permanently override the fan setting.

7-Day Wi-Fi Module Programmable Thermostat is rated 3.8 out of 5 by 16.

They make managing three climate zones a breeze (pun intended). The unit we just purchased was to replace a thermostat that failed. However we are pretty certain it failed because the A/C unit heating circuit failed.

Rated 4 out of 5 by from This is the 5th thermostat of this model that I have purchased and installed with all working pro... This is the 5th thermostat of this model that I have purchased and installed with all working properly. In addition to use as a standard thermostat, I connected one of them in a (weather protected) exterior environment - using an added relay and control circuitry - to control the pump on my solar water heater to lock on when the outside temperature drops below freezing (to protect exposed system pipes/solar collectors from rupturing) as well as when it gets hot enough that circulation fluid might boil within the solar collectors (again leading to pipe rupture). Cons (4 star vs. 5 star rating): (1) Doesn't appear to interface to any other home automation products such as Amazon's Echo or Wink. Adding this interface at the local WiFi level would be a great upgrade, putting this product on-par with those costing 2 or 3 times as much. (2) Thermostats occasionally loose connectivity to supporting WiFi, requiring that they be re-linked. (3) Unlike other more expensive home automation thermostats, these only have a single point of presence at the thermostat vs. having one or more remote sensors to allow the thermostat to serve as a zone controller. Pros: (1) While the initial setup can be tricky (at least the first time, recommend downloading and printing the app's setup directions), the Android RadioThermostat app proved easy to use and very flexible, including both the ability to remotely monitor and set all of the thermostats features plus, on a separate screen, do detailed tracking of both temperature and connected HVAC run-time operation on a 24-hour day basis. (2) These thermostats are MUCH cheaper than other home automation alternatives.

Rated 4 out of 5 by from Purchased the CT50 from Home Depot back in Dec 2011 I paid $99 for the CT-50 back in 2011. I had a few hurdles during installation (i.e. hooking up an additional wire to the furnace and getting the registration with my wireless hub correct), but thanks you Youtube videos the entire process wasn't that painful. I purchased software for my PC (Thermostat for Windows) for I forget but not much that has a decent GUI (graphical user interface). Along with the Android and Apple versions it takes away squinting at the thermostat and has been a God send. I haven't gone on a binge to measure my energy savings, but we are managing our energy consumption much better and on average the temperature settings in the house are 5-8 degrees lower in the winter and about the same in the summer. Combine that with the savings realized when we're away. I highly recommend this thermostat.

Rated 4 out of 5 by from Very happy with this purchase This looks like identical hardware to the LockState LS-60i, but it is 30 dollars cheaper and uses a different web portal to interact with it wirelessly. Unlike the LockState, there are no monthly fees for the wireless feature. The LockState app looks like it is used to control a bunch of stuff around your house - not just your thermostat. Do not get the LS-60i unless you have other LockState products like a camera/lock. As for the CT-50, I have a couple widgets on an android homescreen for each of my AC units. It works great. Setup was kind of a pain because I didn't have a C-wire, but there are youtube videos out there that showed me how to work around it. Also, an iOS device is required for initial wireless setup. Sometimes the connection will drop for a bit, but that might be because of my network and not the thermostat. Overall, I'm quite pleased. I would purchase this again if I were in the market.

Rated 5 out of 5 by from Great product..work like its suppose to.. I bought this back in 2012 when it was 3M-50 Radio thermostat for $99.. I did have to connect a " C " wire called a common wire but that was easy, just used existing wire that was not being used and connected it for "C" wire for power for wifi connectivity..I have had 3M-50 for 3yrs now and have had no problems with it even when I had to replace wireless router...Great product and I did not have to install another thermostat downstair since now I can use my IPhone6 ( had IPhone 3GS when I first installed and setup)downstairs and anywhere else.... FYI: I did have to unhide my wifi signal name when I first setup thermostat and then I re hide signal afterwards and you can setup under WEP or WPA or WPA2 personal.. Mark H.. Austin,TX 4.12.15
