Honeywell Home RTH20B Programmable Thermostat: 5-2 day scheduling
This Honeywell Home thermostat is for the homeowner who wants simple, reliable climate control without a monthly subscription. While many focus on smart features, this model excels at providing consistent comfort through a predictable schedule, perfect for managing your family's weekday routine and weekend relaxation.
You can program separate settings for weekdays and weekends. The large backlit screen is easy to read from across the room, even in low light. It replaces older models like the RTH2300 directly, and the included wall plate makes installation straightforward. Use it with forced air systems, but note it is not compatible with electric baseboard heat. Features like a filter reminder help maintain your HVAC system efficiently. It runs on 2 AA batteries, ensuring operation during power outages.
