What Are Honeywell T9 and T10’s Differences?

In the heating and cooling sector, one of the most recognizable brands is Honeywell. They have a variety of smart thermostat alternatives, each with the Honeywell Home app offering a unique set of features and functionalities. Check out the energy savings that their smart thermostats can provide.

The T9 and T10 Pro provide simple scheduling, geofencing, and support for demand response programs that, in some areas, may be eligible for utility rebates. Homeowners can control the temperature in each room separately, change which room is prioritized, get temperature alerts, and more with the Honeywell Home companion app for iOS.

If you want to acquire a Honeywell T9 or T10 thermostat for your house, do some research to find out which is preferable.

However, the major difference between the two is that Honeywell T10 has a dual fuel mode. It means that it can manage both your gas furnace as well as the heat pump.

Here in this article, we’ll explain the distinction between Honeywell T9 and T10, which is best for your home, etc. This easy yet comprehensive guide will assist you in finding a suitable thermostat.

What Distinguishes the Honeywell T9 from the T10?

The Honeywell T9 and T10 Thermostats unquestionably have a lot of great features. However, they have some distinctive features as well.

That is, if you try one of these thermostats, it may differ depending on your own bias and thermostat traits. You may check it with the details and features that are described in more depth below.

Let us first go through the characteristics and specs of a T9 thermostat in great detail.

  • When compared to T10 thermostats, T9 thermostats have low voltage due to the lower millivoltage.
  • Nothing has changed; T10 has the same functionality as T9 but with a remote program and programmability.
  • On your Honeywell thermostats, T9 has a touchscreen, whereas T10 has a digital screen.
  • T9 offers the same assistant compatibility as T10, which includes Google Assistant, Amazon Alexa, and Siri.
  • T9 uses wire sensing, C-wire, and DIY, while T10 uses more wires and professional installation.
  • Compared to the Honeywell T9, which controls temperature, T10 thermostats can control temperature, humidity, and ventilation. There is only one controllable choice.
  • When compared to T10 thermostats, T9 costs $150 plus any sensor-related variations, while T10 costs $180 plus sensor-related variations.

Features Between Honeywell T9 and T10

Dual Fuel Mode

The most notable differences are adding the fuel mode, which was previously mentioned, and the additional options on the T10. This suggests that you can simultaneously operate your heat pump and gas furnace in dual-fuel mode on the T10.

The gas furnace will take over right away and adjust the thermostat setting to make up for a heat pump failure or halt. The T9 may be a more cost-effective solution for you if you don’t have a gas furnace and aren’t concerned about the dual fuel mode. This will be helpful in saving money over time.

If you’re unsure whether you need dual fuel, you might think about hiring a specialist to examine your system and pump. Using this strategy can help you save time and money when looking for the best thermostat.

Voice Assistance Control and Support

If you want to control the ventilation and humidity in your home, you cannot use the T9. The T9 can only measure humidity and alert you if your levels are unsafe, in contrast to the T10. It won’t be able to change your humidity level, though.

Design and Practicality

As their names already imply, the T9 and T10 are related brothers in the same series. Because of this, they appear to be rather similar at first glance. They actually have the standard rectangle, flat shapes that are present in all thermometers.

The displays on both thermostats are sizable, full-color, and simple to read even from a distance. Even more intriguingly, using the touch screen is responsive as well. One of the aspects I like the most is this. What else could possibly be better than giving your own home a modern twist to make it even more straightforward and pleasing to the eye?

You can always add a plate if you wish, and the two-look lovely on the walls. In terms of size, the T9 is heavier but smaller. It weighs just 1.46 pounds and has dimensions of 3.7 x 4.9 x 0.9 inches. While the size and weight of its rival are 6.2 x 5.8 x 3.1 inches and 0.6 pounds, respectively.

Because you just place the thermostats on the walls, the dimensions aren’t a big deal. Taking into account everything mentioned above, I choose to declare this contest a tie because it can be difficult to tell the two models apart.

The Honeywell T9 and T10 Thermostats are Comparable

The Honeywell T9 and T10 thermostats monitor your house’s humidity and temperature. The sensors can also average the temperatures of different rooms in your house.

The primary thermostat in your home shows the average temperature. The more sensors you have, the more precise your temperature display will be. However, the thermostat and sensors cannot regulate the temperatures independently. They can only provide you with information about the room’s conditions.

Additional significant parallels include:

  • Stylish rectangular flat design.
  • Take temperature and humidity readings.
  • Includes a single sensor.
  • Both can sync with as many as 20 sensors.
  • Enormous displays.
  • Lightweight construction.
  • Each provides voice control.
  • Both are compatible with Honeywell’s Home App.

Additionally, the reviews are comparable. In comparison to the T10, the T9 has an average rating of 4.1 stars on Amazon. With the T10 often costing $30 more, the price difference is also not all that great. One sensor for the T9 and T10 is included in the initial set of components. The price will increase if you purchase more sensors.

Because both thermostats are from the T-series, there are numerous similarities between them. If you want a straightforward thermostat and don’t want dual fuel mode, spend less money and purchase the T9.

Frequently Asked Questions (FAQs)

What distinguishes a Honeywell T9 from a T10?

Answer: While the T10 Pro requires professional installation because of its humidity and ventilation controls, the T9 can “configure itself with its wire-sensing technology and includes a C-wire adaptor, making do-it-yourself installation fairly straightforward.”

Can the Honeywell T10 regulate humidity?

Answer: The T10 Pro Smart Thermostat integrates with Smart Room Sensors so you can control the temperature and humidity in the places that matter while remaining comfortable from anywhere.

Is humidity controlled by the Honeywell T9?

Answer: As was already noted, neither the sensors from Nest nor Ecobee can measure humidity in addition to temperature. Additionally, it’s able to detect motion and presence, allowing it to adapt the system to spaces where it senses an actual human presence.

Does Honeywell T9 Need a C wire?

The Honeywell T9 already comes with a C-wire adapter so you don’t need to buy one separately.

The C-wire, or the common wire, is a requisite for all Wi-Fi based thermostats to draw power from heating and cooling systems. While some brands of thermostats require that their customers buy C-wires separately, Honeywell comes with an adapter if your home is not configured for C-wire use.

How do I know if my thermostat needs a C wire?

If you will be using a Wi-Fi powered thermostat, then you would need a C-wire.

Traditional thermostats that are battery-powered do not usually require C-wire. It is only those that are already integrated with smart home systems like Honeywell that would require C-wire to be used.
