The Nest thermostat is a revolutionary device that makes life easier for many people, and it’s one of the best thermostat brands on the market. They are well-known for their innovative designs, ease of use, and customer service. But does this thermostat work with a humidifier?

Nest thermostats are compatible with numerous humidifier and dehumidifier systems that work independently from your air conditioner. However, it’s advisable to seek professional help for the installation process.

So, if you’re curious about how to use a Nest thermostat with your humidifier, this blog post is for you. We answer the question in more detail and provide a step-by-step guide on using a Nest thermostat with a humidifier. So, let’s jump right in. Shall we?

Nest Thermostat Humidifier Compatibility 

The Nest thermostat is, without a doubt,  one of the best smart thermostats on the market. It is aesthetically pleasing, easy to use, and can be remotely controlled via an app available for both Android and iOS devices.

However, like most people, you may be wondering whether or not the Nest thermostat works with a humidifier. The last thing you need is a thermostat that doesn’t play nicely with the other devices in your home. In such a case, it means that you would need multiple apps to monitor and control your HVAC system, which can be a nightmare for those who are not tech-savvy.

So, does a nest thermostat work with a humidifier? The answer is yes! However, the Nest thermostat is compatible with humidifier and dehumidifier systems that work independently of the air conditioner. Not to mention, the systems have to connect to your thermostat with one or two low-voltage wires.

How to Tell if Your Humidifier is Compatible with Nest Thermostat

Fortunately, you don’t have to be an expert to know if your humidifier is compatible with the Nest thermostat. Furthermore, you don’t need to buy the Nest Thermostat only to find out that your humidifier is not compatible with it.

To find out if your humidifier is compatible with the Nest thermostat, all you have to do is use the compatibility checker. The app lets you check your system’s compatibility during setup, and you can also enter your thermostat wiring into the app to find out if it’s compatible. What’s more, the app will provide directions on how to connect the wires to your thermostat wiring.

Compatible systems typically have the following labels:

  • Dehumidification labels: D, DH, DHUM, DEHUM, D2, DH2, DHUM2, DEHUM2
  • Humidification labels: H, HUM, HUM1, H2, HUM2

Once you’ve confirmed compatibility, it’s advisable to have a professional install your Nest thermostat because there’s a high risk of damage if you attempt to install it yourself, especially if you’re not sure of the correct humidifier and dehumidifier options to go with.

This said, installing your Nest thermostat yourself is possible if you’re comfortable with DIY projects, but do not underestimate the difficulty of this task because several things can go wrong when installing a smart thermostat like Nest in an existing system. 

How Do I Connect My Nest Thermostat to My Humidifier?

So, you’ve figured out that your Nest thermostat is compatible with a humidifier, and you’re ready to connect these two devices. But there’s one problem, you don’t know how to do it.

You have two options. As we’ve mentioned, the compatibility checker provides details on connecting the wires to your thermostat. Therefore, you can follow the guidelines provided to connect your Nest Thermostat to your humidifier.

However, if you’re not sure which dehumidifier and humidifier options you’re supposed to use, hiring a professional for the installation process is advisable. 

If you need someone to install your Nest products and connect to the humidifier, the best thing to do is to contact OnTech Smart Services. These are experts recommended by Google who are familiar with Nest products and how to install them correctly.

However, if you have other issues with heating and cooling in your home, it’s best to contact an HVAC professional. This way,  you can get a complete assessment of your home’s heating and cooling system. They will be able to find any issues with the HVAC unit and provide you with options for how to fix it yourself or hire someone else to do so.

Besides, when you hire an expert, you can get a complete assessment of your home’s heating and cooling system.
