As a homeowner you ought to know the importance of having a thermostat in your home, yet many homeowners don’t see the point in spending money on buying one for their house.
As a result, the importance and value of a thermostat tends to be completely diminished and overlooked by many.
Talking to skeptic owners…
There are great benefits that having a thermostat can bring to your home, such as
However, all thermostats are not made equal as there are different types that will bring you different benefits.
Here is to an honest and deep review about the programmable thermostats from Lux, so you can make the best decision without getting your hands dirty, and seek through tons of catalogues and customer reviews.
Top Features of Programmable Lux Thermostats
GEO/Lux thermostats are part of the programmable thermostats variety from Lux that falls into the category of Smart thermostats, meaning that you can easily program and control them via smartphone through an app.
They also have wi-fi connection, and the installation is easy as the manual comes with instructions that are not difficult or highly technical to follow.
The design of the GEO/Lux is both fancy and practical and comes in black and white finishing colors.
Let’s jump right into the features:
It measures and displays the main important factors such as
- You can sync it with Amazon Alexa as well as the Google Assistant, and the smartphone app is available for both iOS and Android systems. It is easy to schedule and lets you control multiple thermostats in one or more locations.
- It can be powered easily through universal options that comes from 2-AA lithium batteries, to a c-wire, a micro USB or LUX Power Bridge.
- It has room for two-stage heating/one-stage cooling systems that support the most common variety of heaters. It also offers support for blower fan, air conditioning and damper devices.
- Heating and cooling schedules can be programmed throughout the week as well as personalized schedules for each day.
- It has a geofencing system that allows you to set the distance perimeter by yourself. It also allows you to know the current outdoor temperature of the perimeter.
- Its patented Clean Cycle® fan circulation allows to always keep your home fresh and free of pathogens and pollutants that can damage your health.
- You can connect up to 10 terminals that have both conventional and heat pump HVAC (Heating, Ventilating and Air Conditioning) systems. That means that a small-medium house comes in handy for this thermostat.
The TX9100U is not as modern as the Geo but is a fully 7-day programmable energy saving thermostat that is reported to be extremely accurate and have been reliable over the years.
The main features are:
If you’ve always used mechanical thermostats and are not familiar with programmable thermostats , the Lux TX9600TS is the best option to go programmable as it is easy to install and once running, you can mostly forget about it.
The main features include:
Closing in on the set of options, there is the Lux Kono KN-S-MG1, the younger brother of the Geo/Lux thermostat. It mostly delivers the same features as the Geo but with a more elegant and minimalist design that can be personalized according to your taste.
That’s why the Kono KN-S-MG1 comes with various faceplate colors that can be swapped to fit the room’s style, or you can even go further and have your own personal touch painted in a self-customizable faceplate.
Let’s have a look at the features:
Essentially, there is not that much of a dramatic improvement in comparison to the Geo/Lux, as the Konos comes with the exact same features and concept. In addition to that it does seem to come with a wiring bridge for the homes that lack a C wire on their HVAC systems.
How to Install Lux Thermostat
Generally speaking, when it comes to installation, the lux thermostat wiring is quite simple and easy to do, as the user manuals are very detailed and well explained with instructions that are user friendly.
However, in this section we tackle them one by one in an orderly way, the steps to follow and the more general things to look for when installing each one of these Lux models so you have no problem in installing them on your own.
Before installing you want to make sure that your wiring set-up is compatible with the thermostat.
Here are the installation steps...
You’re ready to go.
Lux Thermostat Wiring Diagram
If you have just read the installation section of this article and came here way more confused and anxious than before because you didn’t understand anything, don’t worry. There are times in life when we are faced with new things that scare us.
If you happen to be a person who doesn’t know anything about installing thermostats, let alone properly reading a wiring diagram for installation, keep reading.
In this section we’ll show you the basics of thermostat wiring and installation, so you can have a good understanding of your house heating/cooling system and don’t roll your eyes so far back that you can almost see your brain when having to interpret the thermostat wiring diagram.
So, bear with me…
For starters, when it comes to your heating/cooling system, most vintage systems are basic, meaning that they only have two wires for control.
Those wires work in the same way as an on-off switch, with the slight difference of having a control mechanical or electronic mechanism that regulates the temperature and acts as the main operator of the switch.
The single-stage terminals on the thermostat are defined as,
- W1- W2: Heating
- Y1- Y2: Cooling
The power source comes from a control transformer that can be located outside, or inside the furnace body. This way, the line voltage that feeds the furnace gets decreased to a safe voltage of 24V.
Moreover, after making a series of loops through at least one safety device like an over- temperature shutdown, the power goes up to the thermostat.
Finally, when the temperature descends below the limit, the contacts close and complete the circuit to the gas valve which causes it to open again, start the burner ignition and so have the heating cycle begin.
Then the fan on-auto switch function was introduced to help circulate the air, by using the furnace fan and keeping the circulating air temperature intact. This terminal was labeled ‘G’ and it interacts with ‘R’ terminals for directly turning on the relay’s blower motor.
Lux digital thermostats sometimes need another wire for a terminal labeled ‘C’ to allow a common connection from the control transformer, that will constantly provide 24V power between terminal ‘R’ and ‘C’ to keep the thermostat running.
However, if you can’t or just won't buy that extra cable you can go for battery powered thermostats, but keep in mind that each time the batteries run out of energy, the thermostat just won't do its thing.
Finally, here are the additional terminal interpretations for more complex systems that are second- staged.
Lux Thermostat Swing Setting
Lux programmable thermostats come with a function called swing control. This function plays a key factor on the thermostat, because it allows the adjustment of the range of temperatures in which the thermostat won’t switch on.
All Lux thermostats can be adjusted in 0.25 Fahrenheit degree increments, while some others have larger increments of 1°F.
Generally speaking, the smaller the increments, the more temperature control you have and the more energy you save.
Nevertheless, it seems that the Lux swing control function tends to be overlooked these days by the tendency of going for more high-tech features that allows remote control of the thermostat from a smartphone, rather than look for something that will actually help your HVAC system.
That’s why in this section we help you by clarifying everything you need to know about the Lux swing setting functions, and how you can use these to your advantage to help you save money as well as not wearing out your heating/cooling system way too quickly.
It goes like this, each time the heater raises the room temperature to your programmed set point temperature, the heating cycles per hour function notices when the set point is about to be reached.
So, for example if you have set the temperature at 69°, an anticipator circuit cuts off the heat at a predetermined point, say 68° to stop the heating surpass the mark, so the residual heat will raise the room temperature to the desired 69°.
The swing setting function on the Lux thermostat needs to be performed in time, because the thermostat is configured to automatically exit the screen after 10 seconds of not pressing any button.
The swing setting in the LUX/GEO smart thermostat can be configured by the wheel control that helps you navigate through the options and values
- By pressing ▲, you select a feature.
- By pressing ╳, you go back.
The Lux TX91000U model can be swing set as follows:

In order for you to change the Swing in the TX9600TS model, you’ll need to:
You’re good to go.
The Swing value on the Kono KN-S-MG1 smart model is set by the wheel which will mark a certain number on the screen as you turn it. The Swing Temperature setting is at number 9.
The values you can select are:
