Let me start by saying this thermostat is NOT for DIYers. After my 24-year-old Honeywell unit gave up, three HVAC companies basically shrugged—until the third recommended this beast. The catch? You’ll need a pro to install it (and maybe an extra part, like we did).

The touchscreen is crisp, and programming is oddly satisfying—like using a high-end tablet. I love that it handles our humidifier (rare for 'smart' thermostats) and shows outdoor temp/humidity via a separate sensor. The RedLINK tech feels futuristic, but setup was smooth for our HVAC guys.

Word of warning: Amazon’s listing is misleading. This isn’t plug-and-play—it requires a separate EIM module (sold separately) to control HVAC functions. Also, warranty activation is a dance between Honeywell and your installer. Skip this if you’re not working with a contractor.

When it works (like ours has for 8 months), it’s brilliant. But seeing reviews about units failing after weeks? Terrifying. Pro tip: Buy through your HVAC company, not Amazon—you’ll get better support when (not if) you need it.
