Honeywell RTH9585WF1004 Wi-Fi Enabled Programmable Color Touchscreen ThermostatThe Honeywell Smart Thermostat is a great option for a thermostat that is easy to use and read. Backed by the Honeywell name, which has been involved in HVAC systems for a long time, you know that this full color option will do everything you want it to do and more.

Product Overview

One of the key features of the Honeywell RTH9585 is its ability to adjust to your schedule and use your energy company’s peak pricing to save you money. Using the Smart Response Technology, the thermostat will change settings to ensure that your home delivers maximum comfort when you’re home and save you money when you’re away.

Installation of this thermostat is doable for the experienced DIYer, with clear instructions included in the package. One of the best features of the Honeywell RTH9585 is the wall plate that is installed with the unit. This wall plate allows you to quickly upgrade to future models of Honeywell thermostats in the future.

To get the most out of this thermostat, you require a Total Connect Comfort account, which is easy to sign up for. When you sign up, you can register your thermostat online and then control it from your smart device or any laptop or desktop computer. The app is available on Google Play for Android and the iTunes store for the iPhone, iPad, or iPod touch.

This thermostat is able to be used for both residences and businesses. Out of the box, it comes preset with energy saving modes that preset a schedule. It sets your home temperatures during the day for the following settings:

Period Start Time Heat (Weekday) Cool (Weekday) Heat (Weekend) Cool (Weekend)

Wake 6:00 am 70 degrees F 78 degrees F 70 degrees F 78 degrees F

Leave 8:00 am 62 degrees F 85 degrees F 62 degrees F 85 degrees F

Return 6:00 pm 70 degrees F 78 degrees F 70 degrees F 78 degrees F

Sleep 10:00 pm 62 degrees F 82 degrees F 62 degrees F 82 degrees F

As you can see, the settings are designed to save you money and keep you comfortable.

What are Other Unique Honeywell Features?

Honeywell has a few things that set it apart from its competitors and one of the most significant is the Smart Response Technology feature. What this does Is allow your thermostat to learn how long it takes your home to come to the set comfort temperature.

For example, let’s say that you have a wake up setting where you want your home to be set to 70 degrees. The Honeywell will start your heating system early to make sure that your house is at that temperature at that time.

However, as time goes by, it will learn how your home heats. So instead of starting your heat at 5:00 am and having it at 70 degrees fifteen minutes early, it will start heating at 5:15 am so that it reaches the comfort temp on time.

This is going to save you money in the long run as your HVAC system isn’t going to be running longer when you don’t need it to. This will work not just for heating, but also for cooling. It’s also not just for events, it works during normal maintenance periods as well.

Honeywell has recently decided to create an independent subdivision of itself called residio, which is where all Honeywell thermostats and ADI security systems will be handled from now on. This will enable the separate companies to provide dedicated service to the Home sector of their business, while the Honeywell name will focus on transportation, aviation, and aerospace projects.

This doesn’t mean that current Total Connect Comfort accounts are going away. Residio has announced that they will continue to use the same app design and that rebranding will be about the only significant change to occur. If you are a current Honeywell thermostat user, you should see no change.
