Does the Honeywell T9 Thermostat Control Humidity?


Using the Honeywell T9 thermostat, you can transform your home into a smart system and control your home’s temperature from anywhere. You can even put it on a set schedule to manage the temperature throughout the day. But can the Honeywell T9 thermostat also regulate humidity?

The Honeywell T9 thermostat cannot regulate your home’s humidity. It will, however, measure the humidity in the air and give you a home humidity reading so you can better gauge the heat index.

If you are unsure how to read the humidity measurements on your Honeywell T9 thermostat, we’ve got you covered. In this quick guide, we’ll go over everything you need to know about the Honeywell T9 thermostat and its humidity sensors.

Will the Honeywell T9 Thermostat Regulate Humidity?

Although it cannot directly regulate your home’s humidity, the Honeywell T9 thermostatOpens in a new tab. will give you a percentage reading based on how much moisture is in the air. It comes with a humidity sensor that allows you to measure your home’s humidity and adjust it using a dehumidifier if you so wish. 

How to Read the Honeywell T9 Humidity Sensor?

You can gauge your home’s humidity levels by reading your thermostats sensor in the following way:

  1. Locate your home’s primary Honeywell T9 thermostat
  2. Illuminate the thermostat background by lightly tapping the screen
  3. Find the symbol that looks like a small waterdrop above the temperature reading
  4. Read the smaller percentage number next to the water drop. This is the humidity percentage.

Additionally, you can check the humidity in a specific room if you have more than one sensor located throughout your home. Use the Honeywell Home AppOpens in a new tab. for the following method:

  1. Open the Honeywell Home App on your mobile device
  2. Find and tap the small gear in the top right corner to open settings
  3. Tap “Devices ; Sensors”
  4. Select the specific sensor using the name you gave it during set-up
  5. The sensor reading will give you both the temperature and humidity in that room

When you purchase a Honeywell T9 thermostat, you will receive a single sensor but you can add up to twenty other sensors throughout your home, all connected to the same device. 

How Can You Use Your Honeywell T9 Humidity Reading?

Although your thermostat cannot directly change your home’s humidity, you can utilize the humidity sensor to help manage moisture using a separate dehumidifier. Place individual sensors throughout your home to figure out where you have the most moisture and then place a small portable dehumidifierOpens in a new tab. to reduce your risk of mold and mildew. 

You can also use the following tricks to help reduce humidity:

  • Turn your Honeywell T9 thermostat to auto mode to naturally take moisture out of the air
  • During the summer, keep your home between 72-78 degrees.
  • During the winter, lower your home temperature to around 68 degrees
  • Schedule your thermostat to turn on throughout the day 
  • Measure humidity in every room
  • Manage humidity levels to be between 40% to 65% from winter to summer

While you likely won’t need a dehumidifier in every room, placing a small portable device in rooms that receive the most moisture from outdoors will help keep your home cool and dry throughout the year.

Inversely, if you suffer from the bitter cold and dry winters, you could consider purchasing a humidifier. Rather than sucking moisture out of the air, it will spritz an atomized spray of water back into the air to keep you comfortable and hydrated. 

Either way, your Honeywell T9 thermostat will help you measure and manage humidity throughout the year. If you are still struggling with high or low humidity, you could also contact an HVAC specialist who can offer industrial-strength options. 

Do Any Honeywell Thermostats Control Humidity?

While the Honeywell T9 thermostat cannot directly change your home’s humidity, Honeywell does make a more advanced smart thermostat system that can control your humidifier and home moisture levels. If you want full control, we recommend the Honeywell Prestige IAQ ThermostatOpens in a new tab..

The Prestige IAQ Thermostat can manage all of the following:

  • Home humidity
  • Dehumidification
  • Heating and Cooling
  • Ventilation 

Just like your Honeywell T9, the Prestige IAQ also connects to your home Wi-Fi and you can control it using a mobile app. It’s a slightly pricier option than the T9, but if you are worried about mold and mildew, or you live in an area prone to high humidity, investing a little more in the Prestige IAQ will guarantee you greater comfort and ease of mind. 

Conclusion

The Honeywell T9 only allows you to control temperature. Although it gives a humidity reading, you cannot use the T9 to directly control moisture in your home.

Instead, you can use the humidity reading to better manage where humidity comes in.
