Excerpt: Honeywell’s Classic Round Thermostat

We’ve tested countless thermostats over the years, but the Honeywell CT87K1004 Round Heat-Only Manual Thermostat remains a steadfast favorite. This iconic white dial brings simplicity back to temperature control without sacrificing precision. In our testing, we found its mercury-free design provides remarkably accurate readings within 1°F, while the classic round shape fits seamlessly into any décor.

What impressed us most was its reliability-no batteries, no programming, no Wi-Fi connectivity issues. Just consistent, dependable heat control. The large, easy-to-read numbers and smooth dial rotation make temperature adjustments intuitive, even in low light conditions.

For homes with heating-only systems, we believe this thermostat delivers everything you need and nothing you don’t. Sometimes the classic choice truly is the best choice, especially when it comes with Honeywell’s reputation for quality.
