Most homes wrestle with the same winter headache: a thermostat that drifts, ignores the schedule, or simply looks stuck in 2003. The category has quietly matured, and the current crop handles everything from basic single-stage furnaces to multi-stage heat pumps with surprising finesse. Picking the right one comes down to matching your system, your comfort expectations, and how much you actually want to fiddle with the controls.
A quick honest note before we dig in: “Honeywell total connect thermostats” is a broad search bucket, and not every pick below is a connected smart thermostat in the Total Connect Comfort sense. The Honeywell and PRO1 IAQ models in this lineup lean toward dependable, wall-mounted, manually programmed or non-programmable climate control. That distinction matters for the kind of ownership experience you should expect. Here’s the full lineup.
A Quick View Of The Lineup
PRO1 T725 Heat Pump/Conventional Programmable Thermostat
PRO1 T771 Single Stage Non-Programmable Wall Thermostat
Honeywell TH1100DV1000 PRO 1000 Vertical Thermostat
Honeywell TH2110DV1008 PRO 2000 Programmable Thermostat
PRO1 T701 Single Stage Non-Programmable Wall Thermostat
PRO1 T715 Multi-Stage Programmable Gas Thermostat
Honeywell TL7235A1003 Line Volt Pro Digital Thermostat
PRO1 T721 Non-Programmable Wall Thermostat
Honeywell RTH3100C1002/E1 Digital Heat/Cool Pump Thermostat
PRO1 T805 Single Stage Programmable Wall Thermostat
The Strengths Of Each Pick
The PRO1 T725 earns the top spot because it covers more system types than most thermostats in its weight class. It handles 2 heat/1 cool heat pump setups and 1 heat/1 cool conventional systems, which makes it a sensible pick for households that aren’t entirely sure what’s in the wall or whose equipment has changed over the years.
The 4 sq. in. blue backlit display keeps the readouts readable from across the room, and the T700 platform is straightforward to wire during installation. For households moving up from a basic slider thermostat, the learning curve is short. You spend the first evening setting the schedule, and after that, the wake, leave, return, and sleep blocks quietly do their work.
Noteworthy Benefits
- Dual compatibility with heat pump and conventional systems
- 7-day or 5/1/1 programming flexibility
- Backlit display holds up in low-light hallways
- Large schedule labels for the most-used time blocks
Honest Caveats
- No app or Wi-Fi connectivity for remote adjustments
- Programming setup can feel dated if you’ve used a smart thermostat before
Who It Suits Best
Owners of older homes who want one programmable thermostat that flexes between heat pump and conventional wiring without re-buying.
Consider Something Else When
Households wanting app-based remote control should look at the PRO1 T805 for its larger display and 7-day scheduling rather than heat pump compatibility.
Most home thermostats stop working around 45°F and refuse to call for heat below that. The PRO1 T771 takes the opposite approach and stretches its setpoint range all the way down to 25°F, which is exactly what you need in a detached garage, workshop, or storage shed that has to stay above freezing through a hard winter.
The single-stage conventional design is intentionally simple, with no scheduling to fuss over. You set the temperature, and the thermostat holds it. Swing adjustment and calibration controls help fine-tune the readout to match a secondary thermometer if the room is drafty or oddly placed.
Useful Touches
- 25°F to 90°F setpoint range covers sub-freezing protection
- 4 sq. in. blue backlit display for quick adjustments
- Calibration and swing adjustment for tricky spaces
- Low learning curve, ideal for non-primary buildings
Worth Bearing In Mind
- Not designed for multi-stage or heat pump systems
- No scheduling, so it won’t save energy on its own
- Wiring may require a common wire in some legacy setups
Made For
Garages, sheds, basements, and workshops where freeze protection matters more than programmable scheduling.
Swap It Out When
Main living spaces benefit more from the PRO1 T701, which has a glow-in-the-dark light button and conventional comfort tuning.
Some households just need heat, full stop. The Honeywell TH1100DV1000 PRO 1000 is a vertical, non-programmable thermostat built for exactly that scenario. It measures about 4 11/16 in. high by 2 7/8 in. wide, which fits standard single-gang wall boxes and looks tidy in older homes where the wall plate has been painted around a dozen times.
The premier white finish blends with most trim, and the controls are stripped down to the essentials. There is no app, no scheduling, and no learning curve to navigate. You dial in the temperature, and the system responds. The Honeywell name brings a long track record in HVAC controls, and that brand familiarity is part of the draw.
Where It Delivers
- Compact vertical footprint fits tight wall spaces
- Heat-only focus keeps the interface simple
- Premier white finish blends with classic trim
- Honeywell track record in residential HVAC
Trade Offs
- Cooling stage is not supported
- No programming means manual changes year-round
- Display readability can suffer in bright sunlight
Best Suited To
Older homes and rental units with a single-stage heating system and no need for cooling control.
Skip It When
Heating and cooling households should pick the Honeywell TH2110DV1008 PRO 2000, which adds scheduling and supports both stages.
The Honeywell TH2110DV1008 PRO 2000 is the kind of thermostat that disappears into the background after a week of ownership. It supports 5-2 weekday/weekend programming, which means you set a five-day plan and a separate two-day plan for the weekend. The early-start feature quietly pre-heats or pre-cools the home so the target temperature is reached right when the schedule says it should be.
It works with heat/cool or heat pump systems without auxiliary heat. Temporary and permanent overrides let you nudge the temperature without rewriting the schedule, and the backlit display makes late-night adjustments possible without flipping a hallway light. Compared with the PRO 1000, the addition of a program is the meaningful upgrade.
Useful Highlights
- 5-2 programming covers the workweek and weekend cleanly
- Early-start feature lands on temperature at the right time
- Backlit display eases low-light adjustments
- Works with heat/cool or heat pump without aux
Small Caveats
- Single programming block for Saturday and Sunday combined
- Not compatible with multi-stage heating or cooling
Whose Shelf It Belongs On
Working households with a predictable weekday and weekend rhythm who want the thermostat to handle the routine on its own.
Look Elsewhere When
Households wanting a full 7-day schedule should look at the PRO1 T805, which gives every day its own programming block.
The PRO1 T701 sits on the larger T700 platform, which gives it a slightly roomier display than older T-series models. It supports 1 heat/1 cool conventional systems, so it covers the standard residential setup most homes have. The non-programmable nature means there is no schedule to maintain, which is the right call for rentals or guest rooms where comfort matters more than efficiency.
One detail that earns the “Easygoing Choice” badge: a glow-in-the-dark light button. In a dark hallway at 2 a.m., you can find the controls without a flashlight, and the backlit display kicks in once you press it. For a budget-priced thermostat, that level of consideration is uncommon.
What Earns Its Place
- Glow-in-the-dark light button for nighttime access
- Spacious 4 sq. in. blue backlit display
- Gas or electric configurable for flexible installs
Points To Note
- No scheduling, so efficiency gains are limited
- Single-stage only, not for multi-stage furnaces
Perfect Match For
Rental properties, guest bedrooms, and second homes where tenants or guests want a no-fuss comfort dial.
Reach For A Different Pick When
Heat pump owners benefit more from the PRO1 T721, which adds heat pump support to the same non-programmable approach.
Two-stage gas furnaces run differently from single-stage units, and a thermostat that can call for both stages in sequence keeps the home more comfortable during mild weather. The PRO1 T715 handles 2 heat/2 cool systems and offers 7-day, 5/1/1, or non-programmable modes, so you can scale the scheduling up or down as routines change.
Battery or hardwired power options give installers flexibility on older homes where a common wire may not be present at the wall. The same 4 sq. in. blue backlit display found across the T700 platform keeps the readouts legible, and the glow-in-the-dark light button comes through again here for nighttime use.
Good Reasons To Consider
- Supports 2 heat/2 cool for multi-stage gas furnaces
- Three programming modes: 7-day, 5/1/1, or none
- Battery or hardwired power for older wiring
Things To Consider
- Wiring complexity is higher than single-stage replacements
- Programming menu rewards a careful first read of the manual
Who Will Love This
Households with a two-stage gas furnace who want programmable comfort without paying for a connected smart thermostat.
Another Choice May Suit
Heat pump households with a simpler system should look at the PRO1 T725, which trades multi-stage for heat pump flexibility.
Most thermostats in this roundup run on the low-voltage side of an HVAC system, typically 24 volts. The Honeywell TL7235A1003 sits on the opposite end of the spectrum. It is a 240-volt line-voltage unit, which is exactly what you need to control electric baseboard heaters and similar direct-wired heating equipment.
The on-demand backlight reads clearly in any lighting, and the soundproof operation reduces the clicking that older line-voltage thermostats tend to make as they cycle. A small heating indicator gives at-a-glance confirmation that the system is calling for heat, which is useful in rooms where you want to know whether the system is actually responding.
A Favorable Mix
- 240V line-voltage compatibility for baseboard heaters
- On-demand backlight supports any room lighting
- Soundproof operation cuts down on relay clicking
- Heating indicator confirms system status at a glance
Points To Keep In Mind
- Not a low-voltage thermostat, so it cannot replace standard HVAC controls
- Wiring should be confirmed by a qualified installer
Feature Snapshot
Built With In Mind
Households with electric baseboard or fan-forced heaters that need a 240V-compatible digital control.
Where A Sibling Pick Shines
Conventional central HVAC households should choose the Honeywell TH2110DV1008 PRO 2000, which is built for low-voltage systems.
The PRO1 T721 is the non-programmable cousin of the T725, and that family resemblance shows. It supports 2 heat/1 cool heat pump systems and 1 heat/1 cool conventional systems, so the same thermostat can handle either wiring setup depending on what the home already has in the wall. AA battery or hardwired power is configurable at install.
For homeowners who do not want to manage a schedule but want a thermostat that reads cleanly at a glance, this fills the gap. The glow-in-the-dark light button and blue backlit display are familiar T700-platform touches, and the overall footprint fits a standard wall box without modification.
What Helps Most
- Heat pump and conventional compatibility in one unit
- AA battery or hardwired power options
- Glow-in-the-dark button and backlit display
Practical Considerations
- No scheduling means manual temperature changes
- Single cooling stage, not for multi-stage AC
Right Fit For
Households with a heat pump who prefer a manual dial over weekly programming but still want a clear, modern display.
A Better Fit Elsewhere
Program-loving households should pick the PRO1 T725, which adds 7-day and 5/1/1 scheduling to the same system compatibility.
Heat pumps with auxiliary heat need a thermostat that understands the difference between the two, and the Honeywell RTH3100C1002/E1 is built for that specific job. It works with heat pumps only, which keeps the wiring and controls focused rather than trying to cover every HVAC configuration under the sun.
The soft-touch button interface is a step up from older click-style keypads, and the backlit display reads well in any lighting. The mercury-free design matters for homeowners who want to keep older thermostats out of the waste stream, and the non-programmable operation keeps the controls simple to hand to a family member or renter.
Where It Helps
- Tuned for heat pumps with auxiliary heat
- Soft-touch button interface feels modern
- Backlit display for any lighting condition
- Mercury-free construction for easier disposal
Worth Noting
- Not compatible with electric baseboard or multi-stage systems
- No scheduling, so efficiency gains come from habit
Who Should Grab It
Heat pump households that need a focused, non-programmable replacement and appreciate a soft-touch interface.
Look Elsewhere When
Conventional furnace households should look at the Honeywell TH1100DV1008 PRO 1000 for a heat-only, no-fuss replacement.
The PRO1 T805 is the largest-screen option in the T800 platform, and that extra real estate pays off the moment you start programming. The 7 sq. in. blue backlit display is roomy enough to read a full 7-day schedule at a glance, and the same glow-in-the-dark light button from earlier PRO1 models shows up here too.
Programming modes include 7-day, 5/1/1, or non-programmable, which is unusual at this end of the market. Most programmable thermostats lock you into one scheduling approach, but the T805 lets the same hardware serve a set-and-forget household today and a fully scheduled home next year. Single-stage conventional systems are the only system type supported, so confirm the equipment before installing.
Features That Help
- Extra-large 7 sq. in. blue backlit display
- Three programming modes in one unit
- Glow-in-the-dark light button for low light
- T800 platform brings a roomier physical layout
Honest Caveats
- Single-stage conventional only, not for multi-stage or heat pumps
- Wider footprint may not match older wall plates without a trim ring
Key Product Details
The Right Fit
Families with shifting weekly schedules who want the largest display and the most programming flexibility in a single-stage conventional thermostat.
Not Your Match When
Multi-stage gas furnace owners should look at the PRO1 T715, which supports 2 heat/2 cool systems with similar programming depth.
What To Weigh Before Choosing A Wall Thermostat
The most important step is matching the thermostat to the equipment on the wall. A 240V baseboard heater needs a line-voltage unit like the Honeywell TL7235A1003, while a heat pump with auxiliary heat needs a heat-pump-rated control like the Honeywell RTH3100C1002/E1. Installing the wrong category either trips the system or simply does not call for heat the way you expect.
System stages matter just as much. A single-stage furnace only needs a thermostat that supports one heat call, and overpaying for a 2 heat/2 cool unit gains nothing. Multi-stage systems, on the other hand, run more efficiently when the thermostat can call for low stage during mild weather and high stage only when needed. The PRO1 T715 covers that scenario cleanly.
Programming depth and display size are the everyday comfort factors. A 4 sq. in. display is fine for basic setpoint adjustments, but reading a 7-day schedule line by line gets old fast, which is where the 7 sq. in. screen on the PRO1 T805 earns its keep. Think about who actually adjusts the thermostat day to day, and pick a display size they will use comfortably.
Finally, decide how much schedule management you want to take on. Non-programmable thermostats like the PRO1 T701 and PRO1 T721 are honest, low-maintenance tools that hold a temperature until you change it. Programmable units like the Honeywell TH2110DV1008 PRO 2000 quietly handle the weekday-to-weekday transitions once they are set up. For most households, that small upfront setup pays back through better comfort consistency.
Where Shoppers Slip Up
Common Buying Mistakes
The most common mistake is buying a thermostat before confirming the system type. Open the existing thermostat, look at the wire labels, and note whether the system is heat-only, heat/cool, multi-stage, or a heat pump. Cross-check that against the product’s supported stages before clicking through. A mismatch can mean no cooling in summer or a system that calls for auxiliary heat when it should not.
Another pitfall is overvaluing features that the home does not need. A 7-day programmable unit is wasted on a guest room that sees weekend use only, while a non-programmable model in a busy family kitchen leads to endless manual nudges. Match the feature set to the daily routine, not the spec sheet.
Where The Extra Money Goes
Higher-tier thermostats earn their price through display size, programming flexibility, and system-stage support. The jump from a 4 sq. in. screen to the 7 sq. in. PRO1 T805 is mostly a quality-of-life improvement, but it changes how often you actually engage with the schedule. Multi-stage support on the PRO1 T715 is a real efficiency play in homes with two-stage gas furnaces, where the thermostat can hold low stage longer and avoid the louder, energy-hungry high stage on most days.
The upgrade makes sense when the home’s equipment can take advantage of it. In a single-stage conventional system, the extra money goes unused. In a multi-stage or heat-pump system, the upgrade typically pays back through quieter operation and more consistent indoor temperatures across the seasons.
Frequently Asked Questions
What does “non-programmable” actually mean?
It means the thermostat holds one temperature until you manually change it. There is no weekly schedule to set, and no automatic setback at night. It is the simplest category of wall thermostat, and the right fit for spaces like guest rooms, garages, or rentals where routines change often.
Can I install one of these thermostats myself?
Many homeowners handle a like-for-like replacement, especially when the existing wire labels match the new thermostat’s terminals. Heat-pump wiring, multi-stage wiring, and any 240V line-voltage installation are worth leaving to a qualified HVAC technician, since a wiring mistake can damage equipment.
Do these thermostats connect to Wi-Fi or an app?
The models in this roundup are wall-mounted, manually programmed or non-programmable units. They do not pair with a phone app or smart-home platform, so any schedule changes happen at the wall. For remote control and app-based scheduling, the category moves into a different set of products.
What is the difference between single-stage and multi-stage?
Single-stage systems call for heat or cool at one capacity, either fully on or fully off. Multi-stage systems have two or more capacity levels, so the thermostat can call for low stage during mild weather and reserve high stage for the coldest days. The result is quieter operation and more even indoor temperatures, especially in homes with zoned equipment.
Will any of these work with a heat pump with auxiliary heat?
Yes, the Honeywell RTH3100C1002/E1 and the PRO1 T725 are both designed for heat pump systems, and the T725 specifically supports heat pump configurations with 2 heat/1 cool stages. Confirm the wire count and labeling before installing, and verify that auxiliary heat control matches the existing setup.
Closing Remarks
The right thermostat is the one that quietly handles your home’s specific routine without becoming a daily project. Match the equipment first, pick the programming depth that fits your week, and lean toward the larger displays if anyone in the household besides you will be pressing the buttons. Once those decisions are clear, the rest of the shortlist mostly takes care of itself.
