A:  Yes, The Lux Geo will show you run time of your unit in the form of a graph on the application and the number of run-time hours on the thermostat itself. Lux Technical Support

A:  Absolutely. I love that feature - especially living in a colder climate. FYI, since installing this system, I've saved about 20% in my energy bill. It's a keeper.

A:  Yes. This may be my favorite feature. It tells you how long it runs each hour and totals it up for the day. Just like a FitBit almost.

A:  Yes.

A:  i have two on my house now and it works.

A:  Yez

A:  Yes.

A:  Absolutely. Just set up two locations.

A:  You can have multiple devices and multiple locations set up on your application. You also can share your thermostats with any other email address on the website.

A:  2.4

A:  The WiFi frequency is 2.4ghz.

A:  Have no idea. I recommend you pose this to their tech support folks. It's not in their tech specs. I have three of them and travel a ton. As long as I've had cell service, I can see them all regardless of where I am in the country.

A:  2.4

A:  Only 2.4

A:  I use this thermostat on a radiant heat system with no C wire and no cooling. It works great

A:  yes it will work. Mine works with only 2 wires

A:  I have one in a home with no ac and radiators with a gas furnace.

A:  Yes. Same set-up as I have. Different heat source.

A:  Each system can be different. To properly answer this we at Lux Tech Support request that you contact us and we will gladly assist you.

A:  this one is easier. There are different options. but basically it is far less effort using the smart phone app.

A:  Very easy. Easier on the app than the thermostat.

A:  The programming for this thermostat is very user friendly and is done though the application. There is a process that will ask you what your week is like and take you through the programming right on your phone. You can also either use 4 periods of the day or 2.

A:  I just go to the app on my phone and it asks if you want to set for each day or the same for all days. Then I set the day temp. and when it should start and then the night temp. and when it should start. Very easy

A:  Bill, It's a breeze to change - either from the unit itself - or from the phone-based application. I have mine set to raise the temp from x to y at 6 a.m. and then drop it back down from y to x at 10 pm Monday thru Friday, with different settings for the weekend. I also have an away mode that keeps it at a low temperature in the winter until I'm 50 miles from home - at which time it automatically kicks on so the house is warm when I arrive. I can tell you my heat / electrical bills are down 20% since I installed it. Not sure I read your question right - but hoping you don't make six heat changes per day with your current system. That alone would kill any savings simply from electrical fan cycling. I love this system and have installed four of them [three for relatives and friends]. All are very pleased with the system. Hope this helps.

A:  Yes. I am using it on 2 similar units. Make sure that you have the power wire connected at both ends for it to work.

A:  The Lux Geo is compatible with gas, one stage heat Rheem package units. It will not work with a dual fuel system.

A:  Yes

A:  Yes, you just need to have a lithium battery installed. I bought a Venstar Add-A-Wire from Amazon for $30. This turns your 4-wire system into a 5-wire system--so you will have a C-wire, with no more need for a battery. The thermostat does not update wirelessly without the 5th wire, and not as much information is shown on the display. The Add-A-Wire took me 15 minutes to install.

A:  Yes. My system only had four wires, it had no "C" wire for constant exterior power. So, it uses two size AA batteries to power the unit. It's convenient that LUX includes the two batteries. The instructions made it easy to wire it into the system. I didn't even have to change any "jumper wires" as LUX had them preset for my 4-wire cooling/heat central air system. By the way, my pre-existing wiring was using a blue color wire for the yellow terminal (no yellow wire existed), so be sure to take the photo of the old wiring connections before removing the old thermostat to avoid confusion when installing it.

A:  Yes, the 4 wire system will work with the Lux Geo. You must use batteries to operate the unit. LUX Technical Support

A:  Not at this time

A:  The Lux Geo is compatible with Amazon Alexa if you are using Common wire (system power) or micro USB.

A:  I called a Home Depot representative and she said it works with Alexa. However, I then went to Luxe/Geo's website and it says you need an extra USB chord/adapter not supplied if you don't have a "C" wire. "C" wire usually means a two wire system. From Luxe/Geo's website: 11. What do I need to know if I want to use Alexa with my GEO? Your LUX/GEO needs to be powered from your heating/cooling system via a system common wire (“C” wire), or with the LUX USB Power adapter kit (sold separately). A LUX/GEO using battery only power cannot support Alexa.
