Guide to buying a digital thermostat

There are some features that, if you evaluate them before buying the thermostat, could save you inconvenience or compatibility problems. If you want to know what aspects you should consider to make the most of your money, we invite you to review this guide.

Shopping guide

Thermostat Design

When reviewing any guide to buying the best digital thermostat, design is one of the first features to consider. When you go looking for a thermostat for your heating, air conditioning or water heater system, take into account aspects such as its size and weight, since this device is usually installed in plain sight. Therefore, it is advisable to choose a thermostat that is compact, easy to handle and, if possible, discreet so that it does not affect the decoration in your home.

Likewise, also take into consideration the distribution of your control panel. What direct action buttons does it have, the manufacturing materials of the casing, the screen, backlight systems or visual and sound indicators, among others. By knowing all these details, it will be easier for you to choose which one to buy.

System Compatibility

Another aspect mentioned as relevant in a comparison of digital thermostats is the compatibility of the equipment with the system. Before purchasing any model, you must make sure that it is the right one to meet your needs. Keep in mind that some thermostats have components specially designed to work with a specific system, whether it’s cooling or heating.

Therefore, if you want to avoid performance problems or not being able to enjoy all the benefits of the thermostat, first verify that it is fully compatible with your current system.

Installation requirements

For some users, the issue of installation is of great relevance. Digital thermostats usually have a fairly similar procedure to be installed, based on the steps of placing the base, connecting the poles and reinstalling the mask.

However, to be able to choose a practical thermostat, check its structural design to know how many holes you will have to drill in your wall to install it. Not all users like the idea of ​​modifying a framework and if you want to avoid this, installation requirements are a key part to consider.

Thermostat functions

Although thermostats, whether analog or digital, are basically designed to help you adjust the temperature of your heating or air conditioning systems in your home, there are alternatives on the market that can offer much more than that and, although this influences how much it costs, in the same way you can find an economical and multifunctional model if you look carefully.

Among the functions that a good quality thermostat could offer you is personalized programming, with which you can adjust the room temperature so that the thermostat, using its thermometer, keeps the temperature regulated for your comfort.

Others can connect to the wireless network and offer you remote control of their functions, which is quite useful if you want to get home and find yourself in a more pleasant and pleasant environment.

Power source

Another relevant point that you can consider is the energy source with which the thermostat works. The model you buy may have a port to connect it directly to the current, which are cheaper to use since you do not have to be replacing the batteries, but the ones that are most available on the market are, precisely, the models that work with batteries.

These models have the disadvantage that you will need to replace worn units from time to time, but if your thermostat allows it, you could use rechargeable batteries to save money or also disable the backlight system, as it can consume a considerable amount of energy.

Thermostat Maintenance

Finally, try not to overlook the maintenance of the thermostat and its useful life. As you know, any electronic equipment has a certain useful life, but if you want to extend the life of your digital thermostat, you can take some actions that will help you with that purpose.

One of them is to disable the screen backlight. This will increase the autonomy of the battery and, therefore, you will not have to be removing the mask as often to replace it.

You can also avoid handling it directly if possible. If your thermostat is wireless and you can change settings through the app, do so. This will help keep the buttons looking new and keep the thermostat housing from getting stained from constant handling.
