You probably didn’t wake up excited to shop for a thermostat, but here you are, staring at a wall plate that looks like it survived a remodel and a system that just won’t hold a temperature. The good news: replacing a thermostat doesn’t have to be a project, and the right wall plate can hide a lot of drywall sins behind it. This roundup covers the practical workhorses that work with the kind of system you actually have, plus one wall plate that solves a problem most people forget about.

Inside Each Recommended Option
The THP2400A1027W Thermostat Wall Plate is the kind of accessory people don’t realize they need until they pull off an old thermostat and find a chalk outline of paint, missing drywall, and three generations of caulk. This white back plate sits behind your thermostat to cover that scar, giving the wall a clean, finished look without repainting. It’s a cosmetic upgrade more than a functional one, but for anyone living with a mismatched thermostat footprint, the visual difference is real.
The plate is designed to work with several Honeywell and RTH-series models, which makes it a versatile fit if you’re swapping thermostats over the years. For homeowners upgrading from an older rectangular unit to a square smart model, this is a tidy fix.
Practical Pluses
- Covers old paint lines, holes, and drywall gaps in one move
- Glossy white finish blends with most trim and wall paint
- Compatible with RTH9585, RTH9600, TH9320, and several related models
- Saves the cost and mess of patching and repainting a wall
Things To Consider
- Cosmetic only, it does not control temperature on its own
- You may need to confirm exact dimensions before ordering
Made For
Homeowners swapping an old thermostat for a newer model and wanting a clean wall finish at the same time.
Look Elsewhere When
You’re looking for actual temperature control; pair this with a working unit like the PRO1 T701 instead.
The PRO1 T725 sits on the T700 platform and is built for households running a heat pump with a backup stage, plus the option to fall back to a conventional setup. It supports 7-day or 5/1/1 programming, which matters if your week doesn’t follow a simple weekday/weekend rhythm. A 4-square-inch blue backlit display keeps the numbers readable from across a room, even with the lights low.
For most heat pump owners, the trade-off between programmability and complexity is the real decision, and this one stays approachable. If you’ve been eyeing the T701 but want scheduling, the T725 is the natural step up.
Points In Its Favor
- Supports 2 heat/1 cool heat pump or 1 heat/1 cool conventional systems
- 7-day and 5/1/1 scheduling give flexible weekday plans
- Blue backlit display remains readable in dim hallways
Honest Caveats
- Not for multi-stage gas systems; stick with the T715 there
- Programming takes patience the first time you set a schedule
Key Product Details
Right Fit For
Heat pump households that want a programmable schedule without giving up a simple wall interface.
Consider Something Else When
You have a two-stage gas furnace; the PRO1 T715 handles that configuration more cleanly.
The PRO1 T771 is purpose-built for the corners of a property most thermostats ignore. Its setpoint range stretches down to 25°F, which is exactly what you need in a garage, shed, or workshop where winter temperatures would freeze a standard home thermostat’s brain. Single-stage, non-programmable, simple; the kind of unit you mount, set once, and forget.
Compare that to the Suuwer pick below, which targets the same single-stage crowd, and the difference is mostly the extended setpoint range here. For most home interiors, that’s overkill. For a detached space, it’s the reason to buy this specific model.
Well-Handled Touches
- Setpoint range from 25°F to 90°F handles cold outbuildings
- Blue backlit display readable in dim garages
- No programming menus to navigate, ideal for casual users
Some Limits To Know
- Single-stage only, won’t work with multi-stage systems
- Non-programmable, so no automatic setback schedules
Whose Shelf It Belongs On
Anyone heating or cooling a garage, shed, or workshop where temperatures can swing well below what a home thermostat expects.
A Better Fit Elsewhere
For everyday indoor comfort with a conventional furnace and AC, the PRO1 T701 is the more comfortable pick.
The PRO1 T701 is a textbook example of a “set it and walk away” thermostat. It runs the T700 platform, supports single-stage conventional systems (1 heat/1 cool), and skips the programming menus entirely. The 4-square-inch blue backlit screen is larger than what older dials offered, and a glow-in-the-dark light button makes late-night adjustments less of a fumbling session.
In a home where someone just wants heat in the morning and cool in the afternoon without setting up a schedule, the T701 quietly does the job. It is the T725’s simpler sibling, trading programmability for a cleaner mental model.
Why It Works Well
- Glow-in-the-dark light button for easy night-time operation
- Large 4 sq. in. blue backlit display with clear digits
- Gas or electric conventional compatibility covers most homes
Practical Considerations
- No scheduling, you adjust temperature manually as the day changes
- Single-stage only; multi-stage systems need a different model
Feature Snapshot
Who It Suits Best
Homeowners with single-stage conventional heating and cooling who prefer manual control over schedules.
Not Your Match When
You want a 7-day programmable schedule, in which case the PRO1 T805 is a more capable alternative.
The PRO1 T715 is the multi-stage answer in the T700 family, supporting 2 heat/2 cool gas systems with a schedule you can set as 7-day, 5/1/1, or skip entirely. The same large blue backlit display and glow-in-the-dark light button carry over from the T701, so the user experience feels familiar even with the extra capability underneath.
For two-stage gas furnaces, the T715 helps the system run in low fire more often, which many owners find keeps the temperature steadier. It’s a meaningful step up from the single-stage T701, but only if your equipment actually uses the second stage.
What Makes Sense
- Supports 2 heat/2 cool systems for more even temperature control
- Three schedule modes, including full non-programmable fallback
- Large blue backlit display with glow-in-the-dark button
Points To Keep In Mind
- Wiring is more involved than single-stage installs
- Multi-stage capability only pays off if your HVAC uses both stages
Best Suited To
Homeowners with a 2 heat/2 cool gas system who want scheduling without moving to a learning thermostat.
Where Another Pick Suits Better
Single-stage homes will be just as well served by the simpler PRO1 T701.
The Suuwer non-programmable thermostat targets the most common residential setup in the country: 1 heat/1 cool conventional single-stage. It runs a blue backlight so the screen is readable at night, and the interface is intentionally simple, with just a handful of buttons and a clear setpoint readout. For a basic replacement, that restraint is a feature, not a limitation.
Owners commonly note that the wiring is straightforward for anyone comfortable with low-voltage work, but the wire count matters: it expects 2 to 5 wires, so a quick check of your existing harness avoids a return.
What Works In Its Favor
- Blue backlight keeps the display readable in dim rooms
- Simple button layout avoids the learning curve of programmable units
- Compatible with most single-stage conventional systems
Where It May Fall Short
- Wiring assumes 2-5 wire setups, so older systems need verification
- Non-programmable, so no automatic daily temperature changes
Who Should Grab It
Homeowners with a basic single-stage furnace and AC who want a low-fuss thermostat at a low price point.
Skip It When
You need scheduling, in which case the PRO1 T805 covers that ground with a similar single-stage base.
The Honeywell Home non-programmable thermostat leans on the brand’s long history in climate control. It shows both the current and set temperature on a backlit display, switches automatically between heat and cool, and gives you single-degree adjustments without a programming menu in the way. The white faceplate fits unobtrusively in most hallways.
Compared to the Suuwer, the Honeywell offers auto changeover, which removes the small daily annoyance of flipping between heat and cool modes yourself. Memory storage also helps during power outages, keeping your settings intact.
What Pays Off
- Auto changeover between heat and cool removes manual mode switching
- Backlit display shows current and set temperature at a glance
- Memory storage preserves settings through power loss
Potential Compromises
- Not programmable, so daily schedule adjustments are manual
- Limited compatibility with high-voltage or proprietary systems
Feature Rundown
Perfect Match For
Anyone wanting a straightforward, brand-name thermostat with auto changeover and minimal programming.
Swap It Out When
You run a heat pump only, in which case the Honeywell RTH3100C1002/E1 is a more targeted pick.
The PRO1 T721 is a quietly useful middle ground. It supports both 2 heat/1 cool heat pump systems and 1 heat/1 cool conventional setups, so a homeowner can install it now and not worry if the equipment ever changes. The T700-platform UI means a 4-square-inch blue backlit screen and a glow-in-the-dark light button, both of which carry over from the T701 and T715.
For someone whose HVAC configuration is a little ambiguous, or who plans to swap a heat pump out for a conventional system in the next few years, that flexibility has real value. It’s the kind of unit you don’t outgrow quickly.
Real-World Strengths
- Works with heat pump or conventional systems
- 4 sq. in. blue backlit display with glow-in-the-dark button
- Runs on AA batteries or hardwired C-wire power
Details To Watch
- No scheduling; you adjust temperature by hand
- Configuration must be set correctly for heat pump or conventional use
Quick Facts
Who Will Love This
Homeowners with mixed or evolving HVAC systems who want one thermostat that handles either configuration.
Another Choice May Suit
If you specifically run a heat pump with auxiliary heat, the Honeywell RTH3100C1002/E1 is built with that exact setup in mind.
The Honeywell RTH3100C1002/E1 is a long-standing heat pump thermostat with a soft-touch button interface and a backlit display that stays easy to read. It’s non-programmable, mercury-free, and specifically designed for heat pumps with auxiliary heat, which makes it a focused tool rather than a do-it-all unit. The button presses have a satisfying tactile feel, a small detail that tends to matter after years of daily use.
There are real limits to know. This unit is for heat pumps only, so it won’t work with electric baseboard heat (120-240V), heat pumps paired with gas backup, or multi-stage heating and cooling. For a pure heat pump system, though, it handles the job without fuss.
Noteworthy Benefits
- Soft-touch button interface with backlit display
- Mercury-free construction
- Designed for heat pumps with auxiliary heat
Honest Caveats
- Heat pump only; will not work with gas backup or baseboard heat
- Non-programmable, so daily adjustments are manual
Built With In Mind
Heat pump homeowners without gas backup who want a focused, no-schedule thermostat from a familiar brand.
Reach For A Different Pick When
You have a conventional furnace and AC; the Honeywell Home non-programmable thermostat is a better system match.
The PRO1 T805 is the T800 platform’s take on a single-stage programmable thermostat, and the headline feature is the extra-large 7-square-inch blue backlit display. For anyone who squints at smaller screens, that extra real estate is the whole reason to look at this model over its T700 siblings. It supports 7-day, 5/1/1, or non-programmable modes, so you can run it on a schedule, set it partway, or skip programming entirely.
It is, in effect, the PRO1 T701 grown up: same single-stage 1 heat/1 cool conventional compatibility, but with a bigger display and a real schedule engine underneath. Owners who like to plan their week around a thermostat will appreciate the flexibility.
Practical Advantages
- Extra-large 7 sq. in. blue backlit display for easy reading
- Three operating modes, including 7-day and 5/1/1 schedules
- Glow-in-the-dark light button for nighttime use
Factors To Consider
- Single-stage only, so multi-stage systems need a different model
- Programming setup takes a few minutes the first time around

Single-stage homeowners who want a programmable schedule plus a large, easy-to-read display.
Consider Something Else When
You prefer a dial-and-go interface; the PRO1 T701 is simpler and lighter on the wall.
Choosing The Right Thermostat For Your HVAC System
The single biggest decision is matching the thermostat to your equipment type. A 1 heat/1 cool conventional system is the most common residential setup, and several of these picks, including the PRO1 T701, T805, Suuwer, and Honeywell Home non-programmable, all serve it. Heat pump homes need a different model entirely, with the PRO1 T721 and Honeywell RTH3100C1002/E1 covering that ground.
Wire Count And Compatibility
Before any of the brand decisions matter, the wire count on your existing harness decides which thermostats will physically install. Most modern replacements expect 4 to 5 wires, with older homes sometimes only running 2. Checking the wires behind your current thermostat before ordering saves the headache of a return.
Programmable Versus Manual
Schedules are a real comfort and savings gain for households with predictable routines, but only if someone is willing to set them up. A non-programmable unit like the PRO1 T701 is the more honest choice for users who would rather nudge the temperature by hand than learn a programming menu.
Display Size And Readability
Larger displays like the 7-square-inch screen on the PRO1 T805 make a real difference for anyone with aging eyes or for thermostats mounted across a large room. Smaller 4-square-inch screens are easier to fit in tight wall spaces, and remain readable thanks to blue backlighting.
Key Considerations Across These Picks
Common Shopping Slip Ups
The most frequent mistake is choosing a thermostat by brand familiarity rather than system compatibility. A heat pump home and a conventional home need different thermostats, and “smart” features do not change that. Another common slip is forgetting to count the wires at the wall before ordering; a 2-wire system simply will not accept a 5-wire thermostat.
Where The Extra Money Goes
Higher-tier picks like the PRO1 T805 and T715 cost more because of scheduling engines, larger displays, and multi-stage support. For a single-stage system with a fixed routine, that money often goes unused. Spending up makes the most sense when the equipment actually uses the extra capability, and when the user wants the scheduling, not just the marketing language around it.
Frequently Asked Questions
Do these thermostats work with any HVAC system?
No, each model supports a specific system type, such as 1 heat/1 cool conventional, heat pump, or multi-stage gas. Match the thermostat to your equipment, not the other way around.
What does “non-programmable” mean for daily use?
You set the temperature by hand whenever it needs to change. There is no automatic schedule that lowers the heat overnight or raises it in the morning.
Can I install one of these myself?
Most low-voltage thermostat swaps are a manageable project with a screwdriver and a clear photo of the existing wiring, though comfort with electrical work varies by person.
Will a new thermostat save money on energy bills?
A programmable thermostat can help by avoiding unnecessary heating or cooling, but the actual savings depend on your schedule, climate, and how often you adjust a manual thermostat today.
What is a wall plate for, and do I need one?
A wall plate covers old paint lines, holes, and drywall gaps left behind by a previous thermostat. It is purely cosmetic, but it saves the cost and mess of patching the wall.
Closing Remarks
The right thermostat mostly comes down to matching the unit to your system type, your schedule, and how much wall you want to cover up. Start with the equipment, decide whether scheduling matters, and only then worry about brand and display. The picks above are built to cover the most common residential situations, from a tidy garage thermostat to a feature-rich living room unit.
