Honeywell Lyric T6 Pro

This is the current star of the Honeywell thermostat collection, so it gets more room than the others. The Lyric competes with thermostats like the Nest 3rd Generation and Ecobee4 in the “learning thermostat” niche. It’s available in two models:

  • TH6320WF2003 supports up to 3 heating stages and 2 cooling stages. It’s designed for heat pumps.
  • TH6220WF2006 supports conventional systems with furnace heat and a central air conditioner. It handles two stages of each.

Here’s what you’ll like and perhaps dislike about the Honeywell Lyric T6 Pro thermostat.

Honeywell Lyric pros:

  • WiFi: Connect using the app on an Apple or Android device
  • Programmable or learning: You can program it one of three ways: 7-day (each day is different), 5-2 (weekdays are different than weekends) and 5-1-1 (each weekend day is different). Or, you can let it learn. Change the temperature as you desire, and the thermostat will quickly learn your habits such as when you turn it down at night or when leaving home and when you turn it up again. The thermostat will soon begin automatically adjusting at those times, though you can always override it by manually adjusting it.
  • Geofencing: You use the map on the app to set a neighborhood boundary. The thermostat turns down your HVAC system when you leave the boundary and turns it back up when you return, so you save on energy use and cost without thinking about it.
  • Connected Home: Works with Apple HomeKit and Amazon Echo/Alexa devices, though Alexa is not built into the device, as is the case with the ecobee4.
  • Warranty: The 5-year warranty is excellent.
  • Cost: At less than $125 from most sellers, it costs a lot less than nest 3rd Gen models and somewhat less than ecobee4 and ecobee3 Lite models.

Honeywell Lyric T6 cons:

  • Programming vs. learning: About a quarter of users find the interface challenging and “unintuitive.” The struggle seems to be balancing programming a set schedule with allowing the Lyric to learn and adjust. If your schedule is somewhat random, you might find the Lyric turning your HVAC system up and down at times you don’t want it to. If you don’t have a clearly defined schedule, the geofence mode is designed with you in mind!
  • Connectivity: Issues with WiFi, geofencing and Google Home are infrequent but can be persistent when they occur.
  • Poor Honeywell support: This issue plagues all Honeywell thermostat customers.

Honeywell WiFi Thermostat RTH9580WF

Honeywell WiFi Thermostat RTH9580WF

This is Honeywell’s top-selling touchscreen programmable thermostat. It competes with HVAC brand touchscreen models like the Lennox iComfort, Heil Observer and Carrier Infinity. The $159-$179 price from various sellers is neutral. You can find WiFi thermostats priced higher and lower.

Pros:

  • WiFi: With Apple or Android device and app.
  • Touchscreen: The color display including the background color is customizable. Includes locking screen with password option.
  • Smart Response: This feature begins heating or cooling your home ahead of time, so it’s at the temperature you want at the time you want it rather than starting the cycle at that time.
  • Current weather: The display shows outdoor and indoor temperature and humidity.
  • Connected Home: Works with Apple HomeKit, Google Home, Amazon Alexa, Wink and more.

Cons:

  • C-wire: If your current HVAC system doesn’t include a C wire, you’ll have to install one or try a work-around as described in our C-Wire Guide.
  • Early malfunction: A small percentage of these thermostats seem to fail within a year. Issues getting Honeywell to replace them might occur.

Smart Thermostat with Voice Control RTH9590WF

RTH9590WF

This latest offering from Honeywell is a feature-rich WiFi thermostat, the next step up from the Honeywell RTH9580WF reviewed first. The big step forward is voice control using voice recognition technology directly to the unit or through the Total Connect Comfort app. The app with voice control works with other models too. Apart from voice control, most features and the pros/cons are the same as those of the RTH9580WF. The differences are listed in the pros and cons below. This is a $200+ thermostat from a range of sellers.

Pros:

  • Voice: Hands-free control of the thermostat using basic commands like, “make it three degrees cooler” or “I’m feeling warm,” signal changes.
  • Internet time sync: On time-change weekends, after power outages or any other time the display time is wrong, the thermostat will automatically adjust to the correct time.

Cons:

  • Honeywell support: As we’ve noted already, Honeywell customer service and support are poor.
  • Reboots: The thermostat needs rebooting more frequently that most WiFi thermostats.

Honeywell WiFi Thermostat RTH8580WF

RTH8580WF

This thermostat has many of the same features as the RTH9580WF including a touchscreen control, but the display isn’t color. It does not show outdoor weather conditions or indoor humidity on the main screen. The Honeywell RTH8580WF thermostat is competitively priced starting at about $90 from various sellers.

For Honeywell RTH8580WF pros and cons, see those for the Honeywell RTH9580WF above, but with the model differences we just noted. This unit doesn’t require a C wire. Some users have trouble connecting the unit to WiFi. Others report poor experiences with Honeywell support – or lack of support!

Honeywell WiFi Thermostat RTH6580WF

honeywell-thermostat-RTH6580WF

This WiFi Honeywell thermostat is an older version of the RTH8580WF, though it is still sold widely and delivers reliable performance for less than $90 from most sellers. This points out one of the issues some have with Honeywell: It makes many quite-similar thermostats without clear distinctions between them.

Pros:

  • Versatility: This is a universal thermostat that supports up to two stages each of heating and cooling including heat pump and hydronic 24V systems.
  • Display: While not color, the display is crisp, clear and easy to read with large black characters on a light-green screen.
  • Installation: DIY installation is easy.

Cons:

  • Looks: The style is traditional, so it doesn’t have the sleek look of the nest or ecobee thermostats.
  • C Wire: This unit requires a C wire.
  • Connectivity: Some users have a difficult time getting the thermostat to connect to WiFi at initial setup. To help connectivity, set up the thermostat using a smart device and the app.
  • Failure: A small percentage of Honeywell thermostats don’t work right out of the box or fail within the first six months. Some report difficulty getting Honeywell to honor its warranty.

Which Honeywell Thermostat is Right for You?

You’ve got a range of options based on features and price. All models support most 24-volt HVAC systems. If you’re willing to spend more for voice control (RTH9580WF), color touchscreen (RTH9580WF and RTH9590WF) or a thermostat with a touch of decorative style (Lyric T6 Pro), then you’ve got options. If you’re content with the convenience of a WiFi thermostat that controls your HVAC system reliably but without upscale features, the affordable RTH8580WF and RTH6580WF will certainly get the job done.
