Buyer profiles are helpful here: a rental property owner may prefer straightforward programming and reminders, a homeowner upgrading from a non-programmable unit will value a clear display, and a budget-conscious buyer will lean toward the simplest programmable option that still saves energy. The products below are organized to help you compare features, suitability, and potential limitations at a glance.
Honeywell Home RTH20B — Simple 5-2 Schedule
The RTH20B offers 5-2 day scheduling, making it suitable for homes with distinct weekday and weekend routines. Best for buyers replacing an older Honeywell model or upgrading from a basic non-programmable thermostat, it provides a large display and straightforward controls. The device can remind users to change the air filter and allows display customization for easier daily use. A potential drawback is that it may feel limited for households seeking advanced programming beyond 5-2 options.
Honeywell TH1100DV1000 — Backlit Digital Comfort
The TH1100DV1000 is a low-cost, heat-only option with a clearly readable backlit display and a standard 40-to-90 F temperature range. It’s best for budget-conscious buyers who want a simple, reliable programmable thermostat for single-stage heating. It is a practical upgrade from a non-programmable unit, especially in spaces where visibility at night matters. A limitation is that its feature set remains basic, with fewer scheduling options than higher-end models.
Honeywell Home RTH7600D — Touchscreen Convenience
The RTH7600D presents a large touchscreen with 7-day, menu-driven programming. It’s best for households that want an intuitive, modern interface and flexible scheduling. The device supports home/away temperature settings to help reduce energy use when no one is home. It also offers temporary and permanent hold options for extended absences. A potential caveat is that touchscreen models can require occasional calibration or more careful cleaning to maintain legibility over time.
Honeywell Home Non-Programmable X1N — Simple Baseline
Although non-programmable, the X1N model is included for buyers who may be transitioning away from older non-programmable units and need a straightforward interface with a clear display. It emphasizes ease of installation and simple operation, making it best for those who prefer minimal scheduling. If you want a programmable option, consider the other five models in this guide.
Honeywell Home RTH22B — Flexible 7-Day Options
The RTH22B supports 7-day programming with flexible scheduling, including multiple day formats (7-day, 5-1-1, 5-2, or non-programmable). Best for households needing robust scheduling that can accommodate various routines across the week. It’s a good choice for those upgrading from a basic model who still want an adaptable program for both heating and cooling in some configurations, though it remains primarily designed for 1- to 2-heat systems. A caution is that complex setups may require careful matching with existing furnace wiring.
Lux Pro PSP511LC — Quick Setup With Backlight
The Lux Pro PSP511LC is designed for easy weekday/weekend programming with a backlit display for nighttime visibility. It allows up to four daily periods, enabling a balanced heating schedule without overcomplicating setup. Best for buyers who value quick programming and a straightforward interface. A limitation is that its feature set is modest compared with touchscreen models or more advanced programmable units.
Buying Guide: Key Purchase Considerations
What should guide your choice among heat-only programmable thermostats?
- Programming flexibility: Do you need 5-2 or 7-day scheduling, and how many periods per day?
- Display readability: Is a backlit or large touchscreen display important for ease of use?
- Installation ease: Does your current wiring match the thermostat’s requirements (single-stage, heat-only systems are common)?
- Energy-saving features: Do you want home/away programming and hold options to optimize comfort and bill savings?
- Brand ecosystem: Are you invested in a specific brand for future upgrades or compatibility with other devices?
Simple vs. Advanced: Which Should You Choose?
- Choose simple if you mainly want reliable temperature control with basic scheduling and minimal setup.
- Choose advanced if you value a touchscreen, multiple scheduling options, and more customization for daily routines.
Installation and Compatibility
Most heat-only programmable thermostats cover standard 1H/1C or similar single-stage configurations. Before purchase, verify your system’s wiring (number of wires, heat-only designation) and confirm the thermostat is compatible with your furnace. If you’re replacing an older Honeywell model, replacement compatibility can simplify installation.
