Against the RTH6360D, it’s slightly less advanced but noticeably cheaper, making it the better pick for ultra-tight budgets or temporary setups. Compared to the Suuwer S705, it offers broader compatibility and Honeywell’s proven reliability, though it lacks dual power options. It’s ideal for rental units, garages, or secondary spaces where basic automation is enough. For no-frills, dependable control, the RTH2300B proves that sometimes the simplest thermostat is the smartest choice.

The Honeywell RTH2510B is the unsung star of weekly scheduling, offering true 7-day flexibility at a price that barely dents your wallet. For households with irregular routines—shift workers, freelancers, or chaotic family calendars—this thermostat is a game-changer. With independent programming for each day, ±1°F precision, and Early Start logic, it ensures your home hits the right temperature exactly when you need it, even if your schedule doesn’t repeat. It’s the rare budget model that doesn’t force you to compromise on customization.

In daily use, the backlit display and one-touch controls make adjustments simple, while the filter and battery reminders keep your HVAC system running efficiently. The Early Start function is a standout—it calculates how long heating or cooling takes and begins early enough to meet your schedule, a feature usually reserved for pricier models. It’s compatible with heat pumps (with or without backup) and most conventional systems, though it can’t handle multistage setups. Like other non-Wi-Fi models, it offers zero remote access, so last-minute changes require a trip to the wall.
