Smart Thermostats Face-Off: Honeywell RTH9585WF vs. Honeywell T9

When it comes to upgrading your home's heating and cooling controls, the Honeywell RTH9585WF and Honeywell T9 stand out as compelling contenders. Both devices serve residential users with robust features, including multi-stage heating capabilities and compatibility with boilers, as well as support for battery operation powered by AA batteries, boasting about a 12-month battery life.

Both can be mounted on the wall with included wall plates and display 3.5-inch screens with adjustable brightness. However, their approaches to smart home integration and automation diverge sharply. The RTH9585WF is classified as a programmable thermostat focusing on core scheduling and control. At the same time, the T9 elevates the experience as a smart thermostat equipped with advanced sensor support, expanded automation modes, and richer connectivity options, including IFTTT integration.

Honeywell RTH9585WF: Reliability with Simplified Scheduling

The Honeywell RTH9585WF is an excellent choice for those who value straightforward programmable thermostat functionality combined with dependable performance. Its gray exterior is designed for residential use, offering compatibility with a broad range of HVAC systems, including both gas furnaces and boilers, and cooling systems such as central AC and heat pumps. The device supports adaptive scheduling, which helps optimize energy use by learning your preferred heating and cooling patterns over time.

While it does not include remote or motion sensors, the RTH9585WF comes with standard historical data tracking, enabling insight into temperature changes and system activity. The display features adjustable brightness and includes a control lock and child lock to prevent unauthorized changes. Although it lacks proximity activation for the screen, meaning you need to interact to wake the display physically, it still offers basic cloud connectivity for remote control through a mobile app.

Regarding safety, the RTH9585WF includes overheat protection and sends maintenance alerts to keep the HVAC system in check. The unit meets FCC regulatory standards and is built in the USA with an expected lifespan of approximately 10 years.

Honeywell T9: A Leap Ahead in Smart Home Integration

Stepping into the realm of intelligent home climate control, the Honeywell T9 impresses as a feature-rich smart thermostat tailored for tech-savvy users seeking comfort and efficiency. Unlike the RTH9585WF, the T9 emphasizes sensor-based automation with built-in motion detection and support for remote sensors, allowing for precise room-by-room temperature management based on occupancy. This is particularly valuable in larger homes where the temperature varies between zones.

The T9 incorporates advanced scheduling features, including eco mode and sleep mode, optimizing comfort while cutting down energy usage. Furthermore, it supports integration with IFTTT, enabling users to create customized smart home scenes that harmonize with other devices; an edge that the RTH9585WF lacks.

User interaction is enhanced by a proximity-activated display, meaning the screen lights up as you approach, improving usability in low-light conditions. Despite a slightly deeper profile than its competitor, the T9 remains wall-mounted with straightforward installation.

Safety features mirror the RTH9585WF, but the T9 holds additional CE certification alongside FCC compliance, suggesting higher adherence to international standards. It maintains a similar voltage range and standby power requirements but offers a more modern interface underpinned by cloud connectivity.

Quick Take

The Honeywell RTH9585WF excels in delivering reliable, easy-to-use programmable thermostat capabilities with adaptive scheduling and a solid safety profile. On the other hand, the Honeywell T9 shines through its smart features, including motion and remote sensors, eco-friendly modes, and seamless smart home system integration via IFTTT. Both thermostats maintain comparable battery life and HVAC compatibility.

Bottom Line

For anyone aiming to embrace smart home technology with granular control and automation, the Honeywell T9 represents a more future-ready pick, offering comprehensive sensors and advanced smart features without significantly higher cost. Those who prioritize a straightforward, dependable programmable thermostat might find the Honeywell RTH9585WF a practical and cost-effective solution.

Verdict

  • Winner: Honeywell T9 - Its extensive sensor support, smart automation modes, and broad regulatory compliance make it a superior smart thermostat for modern homes.
  • Runner-up: Honeywell RTH9585WF - A solid programmable thermostat that covers all essential bases with simplicity and reliability, ideal for users new to smart thermostats.
