GoControl GC-TBZ48 Thermostat

GoControl GC-TBZ48 Thermostat

I never really warmed up to the idea of a smart thermostat. I thought if I had a manual thermostat, why should I invest extra money and buy a new device that does exactly the same thing?

However, it became apparent pretty soon why a smart thermostat is way better than the manual one I already have. Firstly, the former lets me customize all the settings remotely. 

I don’t have to go to the device and set all the settings every time.

All I have to do is log in to the app and turn the device on. And when I open the door, I’ll be greeted with a cozy and warm living room where I can just relax (or cold on if its summers).

Moreover, I talked to a few friends and realized that smart thermostats are more eco-friendly and cost-efficient than manual ones. These units let you schedule the HVAC (Heating, Ventilation, and Air-conditioning) system and also track the energy it uses.

Thus, after evaluating all of the pros and cons, I set off to find my perfect smart thermostat. I came across GoControl GC-TBZ48 and decided to buy it!

Things to consider before buying a Smart Thermostat

The following are some of the things that I considered before buying GoControl GC-TBZ48. These helped me chose the ideal unit for my place so I hope they will help you too!

1. Ease of Installation

Even before looking at all the different features the unit had, I researched how easy it was to install it. I did this because I wanted a unit that I could easily set-up instead of seeking the assistance of an electrician.

The best way to find whether a unit is easy to install or not, look at the customer reviews since they are the most authentic source to find out the truth.

2. Type of Thermostat

There are two advanced types of thermostats that you will find in the market. The first ones are the programmable ones. 

These units do not require a Wi-Fi connection and allow you to set various temperatures throughout the day. However, there isn’t any voice control or remote control options.

The major difference between the above-mentioned device and Smart thermostat is that it uses Wi-Fi connectivity for operation, allows remote controlling, and is energy efficient. However, you need to be careful while selecting a smart thermostat since different models work with different HVAC systems.

3. Your HVAC system

As mentioned in the above point, your HVAC system might require a special kind of smart thermostat that is compatible with it. These systems come with numerous options; some only have a heat pump, while others might have a gas furnace, different speed system, air conditioner, dual fuel system, etc.

Your ideal thermostat must have the capability to control all of these different systems of your HVAC optimally. For instance, if your system comprises only of a heat pump, then you need a thermostat that can support the auxiliary heat function.

So, if you do not know the type of systems you have at home or the kind of thermostat that you need to buy, ask your local technician.
