Wi-Fi 7-Day Programmable Smart Thermostat with Digital Backlit Display

I have been very happy with this thermostat. I especially appreciate the wifi capability that allows me to activate the heat or AC before we get home when we have been away. However the installation instructions that came with it were very unclear and inadequate for getting the wifi set up.

Hi Fernie, to verify the compatibility between this thermostat and your system we need to know how many total wires you have and which terminals are being used on your current thermostat. At your convenience, please feel free to contact our team to check compatibility at 1 (800) 468-1502 Monday - Friday 9 am to 8 pm, Saturday - Sunday 9 am to 5 pm CST.

it does but I cannot say for how long as we have only had 2 outages and both only lasted a couple of hours.

security is that you set your password for the Honeywell system that allows you to control it. If someone else finds out your password then, yes, they could alter heh temp settings.

Hi Al, This will depend on your system type, please tap link below to access our thermostat wiring compatibility tool. https://www.honeywellhome.com/us/en/thermostat-wiring-compatibility/

Check thjat you have power to the blue (I think it was the blue one) wire that actually supplies power to the thermostat. i had the blue wire but it wasn't connected so had to have an electrician come in to connect it.

Sorry if I was unclear. I marked the initial answer as unclear because my objective is to be able to have the heat come on without ever using the auxiliary/emergency heat (I want to avoid having the extra energy required when this happens). Using the temperatures in my question as an example, will it heat the house from 62 degrees at night to 70 degrees at the 8am wakeup/morning just using regular heat?

YES! I have two houses. I have two of these at each house (2 units at each house). When I'm at the lake house, I can do whatever I want to temps at the main house in another town, and when I'm at the main house, I can turn on and off, adjust the temp, change from a/c to heat or whatever I want at the lake house. As long as both houses have WiFi, or the one where you want to install this has WiFi, it's GREAT! When I get to the lake house, it's nice and cool already, or warm, whichever needed. You can also program them for periods of time like other thermostats, and change the schedule remotely. Easy to install too (I'm a woman LOL, but pretty tech savvy.) Also go to their website to learn more... https://www.honeywellhome.com/us/en/products/air/thermostats/wifi-thermostats/wi-fi-7-day-programmable-thermostat-rth6580wf1001-u1/ They are also making many newer models. This one is inexpensive and works fine. Others just do more stuff. Hope that helps!

Hi Jw, this WiFi thermostat requires a C wire.

Not really sure what your question is ... This thermostat is wired in wherever your existing one is, or in a new installation, the HVAC control wires are brought to a convenient location representative of the average temperature for a given setting, e.g. typically somewhere near the center of the home. It is also authenticated into your wireless network, with internet access, so that you can control it from afar using the mobile phone app... similar to using an ADT or SimpliSafe app to control your home security system...
