Fascinated and curious about this invention, I started searching every online site to find information about smart thermostats and if they were worth buying. Following is all my research and the unit I ended up buying; the powerful, the phenomenal, and the ever-perfect Venstar ColorTouch T7900! If you want to find out more about it, then keep on reading!

Smart Thermostats

Smart thermostats are small electrical devices that help with home automation and are mostly concerned with controlling a place’s heating, ventilation, and Air-Conditioning (HVAC) Systems.

They are similar in function to a manual thermostat except for the fact that you can easily control them using your smartphones or a virtual assistant. Also, the biggest advantage that smart thermostats have over manual ones is remote accessibility.

Who should buy smart thermostats?

In my opinion, a smart thermostat is always better than a manual type. I mean, who does not love managing and doing all of their tasks while laying in bed and Netflix-ing? So, if you are someone who wants remote accessibility of their thermostat even when they are out of the country and want to be reminded when to change the filters instead of checking the device themselves every few days, then you should buy a smart thermostat.

Factors to consider before buying Smart Thermostats:

Following are some of the factors that I kept in my mind while searching for Venstar’s ColorTouch T7900. It helped to make my searching hunt much short, so I am sure they will help you too.

1. The Set-up

The initial and primary aspect to assess is the type of HVAC system it supports and its c-wire requirements.

HVAC System

The type of HVAC system installed in your house is the main factor that will determine the kind of thermostat you need for your place. While some thermostats work with single-stage ones, others are only compatible with multi-stage systems.


One thing that you should know about smart thermostats is that they require more energy than a pair of batteries can give. On the other hand, they cannot be connected to a power source at home because there is a risk of overloading and overheating.

So how exactly do you power these devices? Via the HVAC systems! Yes, these devices get their power from the system via a common wire (or more commonly known as the c-wire. So before anything, check yourself or call a professional to check your system to see if it possesses a c-wire or not.

Most thermostats come with a small installation kit that possesses a c-wire. However, if there isn’t one in the kit, then just purchase it from your local store and install it yourself or ask a professional to do so.

2. Ease of Use

There are arrays and arrays of thermostats in the market. They come in every shape and size. Some adorn a wide display screen with a touch screen while others feature several buttons for control. No matter which option you choose, always check the responsiveness of the thermostat. Also, note the size of the screen.

Can you read all the information displayed on the screen clearly? Can you see the screen even during the brightest day? How easy it is to access the menu bar and other features?

An ultimate thermostat, in my belief, should be the one that allows you to understand all of the data at a glimpse and should be simple in functionality.

3. Compatibility

Almost all smart thermostats have Wi-Fi compatibility so that they can connect to your home network and let you remotely access the device from anywhere and at any time. So, make sure to check if the Wi-Fi connectivity is strong or it keeps disconnecting.

Furthermore, smart thermostats are controlled using either a mobile application or using a virtual assistant. So always check if your phone can access the application and download it and the same is the case with the virtual assistant.

If you are a couch potato like me, I suggest you pay heed to this point. It will make using a smart thermostat almost fun!

4. Installation Process

While some thermostats come with a small kit, labeled wires, and a comprehensive manual to make the installation process effortless and quick, others don’t. So, make sure that you find out how effortless or complex it is to set-up the device.

Though, if you do not understand or are struggling to install the device, call an electrician right away! You do not want to mess up your HVAC system or the different wires that power your house, now do you?
