A Closer Look At Each Pick
The PRO1 T725 sits in that useful middle ground where a household runs a heat pump for most of the year but falls back to a conventional system during deep-cold snaps. It targets 2 heat/1 cool heat pump setups as well as 1 heat/1 cool conventional systems, so the same wall unit can ride out a furnace swap without needing a replacement.
Compared to the simpler PRO1 T771 covered later, the T725 adds 7-day and 5/1/1 scheduling options, a 4 sq. in. blue backlit screen, and battery or hardwired power. For most mixed-system homes, that scheduling flexibility alone is the reason to consider it over a non-programmable model.
What Works In Its Favor
- Handles both 2H/1C heat pump and 1H/1C conventional wiring, useful during system changes
- 7-day and 5/1/1 day programming for tailored weekday and weekend routines
- Large 4 sq. in. blue backlit display remains easy to read from across the room
- Glow-in-the-dark light button helps during late-night adjustments
Worth Noting
- No Wi-Fi or smart-home connectivity, so it can’t be added to a HomeKit scene
- Programming menus take a few extra button presses to learn
Quick Facts
Who It Suits Best
Homeowners with a 2H/1C heat pump or a mixed-system setup who want scheduling without paying for app connectivity.
Where Another Pick Suits Better
The Mysa Smart Thermostat is the better fit for rooms with high-voltage electric baseboards and a HomeKit-first household.
Detached spaces rarely need app control or weekly schedules, which is exactly where the PRO1 T771 earns its keep. It targets 1 heat/1 cool conventional systems and stretches to a 25°F to 90°F setpoint range, the kind of low-end reach that matters when you’re trying to keep pipes from freezing in a garage or workshop.
Side by side with the PRO1 T701 that follows, the T771 leans further toward specialty spaces. The T701 is more of a daily-room pick, while this one handles the corners of the property where you want reliable heat without a learning curve.
The Upside
- Wide 25°F to 90°F setpoint range supports both freeze protection and summer cooling
- Simple non-programmable layout keeps operation obvious for occasional users
- 4 sq. in. blue backlit display stays readable in dim garage lighting
- Calibration and swing adjustment help fine-tune to the room’s actual feel
Trade Offs
- No smart-home or Wi-Fi features, so remote control isn’t an option
- Single-stage only, so it’s not the right match for multi-stage equipment
Feature Snapshot
Made For
Garages, sheds, workshops, and other outbuildings where simple, wide-range control beats smart features.
Consider Something Else When
The PRO1 T701 is a friendlier pick for indoor living spaces that only need basic single-stage comfort.
The PRO1 T701 is the kind of thermostat you set once and forget about, which is genuinely useful in rooms that don’t need a schedule. It runs on 1 heat/1 cool conventional systems, supports gas or electric configurations, and uses AA batteries or a hardwired common wire for power.
Where the T771 leans toward outbuildings, the T701 feels more at home in a hallway or guest room. The glow-in-the-dark light button is a thoughtful touch you notice the first time you reach for it in a dark bedroom.
Useful Touches
- Glow-in-the-dark light button makes late-night adjustments painless
- 4 sq. in. blue backlit display reads clearly from a few feet away
- Gas or electric system support covers most conventional setups
- Battery or hardwired power adds installation flexibility
Small Caveats
- No scheduling, so the temperature stays where you set it
- No app or voice control, which may be a deal-breaker for smart-home households
At A Glance
Best Suited To
Guest rooms, secondary bedrooms, and small offices where a manual set-and-forget approach actually fits the routine.
Not Your Match When
The Mysa Smart Thermostat fits much better in a HomeKit household with electric baseboard heating.
Bigger homes with two-stage gas furnaces and central air need a thermostat that actually knows what to do with the extra stages, and the PRO1 T715 fits that brief. It supports 2 heat/2 cool systems and offers 7-day, 5/1/1, or fully non-programmable modes, so you can pick the level of automation that matches how you live.
Versus the single-stage T701 earlier in this list, the T715 opens up the option of running a more efficient low-fire stage during mild weather. The glow-in-the-dark light button and 4 sq. in. blue backlit screen are familiar PRO1 touches, so the user experience feels consistent if you’re upgrading from an older unit in the same family.
Key Advantages
- 2H/2C support unlocks two-stage gas furnace control for tighter comfort
- Three scheduling modes give you room to scale back automation if routines change
- 4 sq. in. blue backlit display with glow-in-the-dark button for easy nighttime reads
- Battery or hardwired power options simplify retrofits
Honest Caveats
- Programming depth is a small step up from a single-stage unit, so first-time setup takes longer
- No built-in Wi-Fi, so it won’t tie into a HomeKit or Alexa routine out of the box
Whose Shelf It Belongs On
Owners of two-stage gas systems who want programmable comfort without layering on a smart-home app.
A Better Fit Elsewhere
The Google Nest Learning Thermostat (4th gen) is the smarter choice for a household that wants the thermostat to build its own schedule.
The PRO1 T721 is a quiet utility player that covers either a 2H/1C heat pump or a 1H/1C conventional setup, which is the exact transition zone many additions and renovations sit in. It uses the same T700 platform as the T725, so the on-wall feel is familiar if you’re stepping up from an older PRO1 unit.
Compared to the T701, the T721 adds heat pump compatibility, which is the meaningful differentiator. In most mixed-fuel homes, that single feature can save you from buying a different thermostat when the equipment changes.
A Favorable Mix
- Switches between 2H/1C heat pump and 1H/1C conventional without rewiring decisions
- 4 sq. in. blue backlit display and glow-in-the-dark light button for easy visibility
- AA battery or hardwired power keeps installation flexible across older homes
Possible Compromises
- No scheduling, so you adjust manually for seasonal changes
- No app or voice control, which limits its role in a HomeKit setup
Core Details
Perfect Match For
Additions, converted porches, and homes transitioning from a conventional furnace to a heat pump.
Skip It When
The Sensi Touch Smart Thermostat is a stronger fit when you want a color touchscreen and Wi-Fi control.
Most smart thermostats quietly ignore high-voltage electric heat, which is why the Mysa exists. It targets 120V to 240V electric baseboards and fan-forced heaters, with load support up to 1900W at 120V or 3800W at 240V, and it works with HomeKit, Alexa, and Google Home.
That HomeKit support is the headline. Compared to the non-smart PRO1 units earlier, Mysa lets you build scenes like “Bedtime” that lower the bedroom baseboards while keeping the living room warm, all from your iPhone. The catch is the wiring: it needs at least four wires including a neutral or a second live wire, so older two-wire installations will need an electrician’s help.
A Few Highlights
- Direct HomeKit support means Siri can drop the temperature hands-free
- Handles up to 3800W at 240V, enough for most residential baseboard zones
- Free companion app delivers temperature and humidity alerts from anywhere
- Wi-Fi programmable schedules for room-by-room comfort
Things To Consider
- Won’t work with low-voltage systems or two-wire setups, which limits older homes
- Professional installation is commonly needed if the existing wiring falls short
Who Will Love This
HomeKit households with electric baseboards or fan-forced heaters that want app and voice control per room.
Look Elsewhere When
The PRO1 T725 is the more sensible swap for a central heat pump that doesn’t need high-voltage handling.
The Sensi Touch ST75 leans into a color touchscreen, which makes everyday adjustments feel closer to a phone than a wall switch. It’s a Wi-Fi programmable model with a mobile app, geared toward DIYers who want a guided install and data-privacy controls baked in.
Set against the non-smart PRO1 units earlier, Sensi’s value is the app and the touchscreen. Just keep in mind the C-wire requirement, since older homes without a common wire may need an adapter or a small wiring update before this one powers up cleanly.
Where It Excels
- Color touchscreen gives quick, visual feedback for changes
- Companion mobile app supports scheduling and remote adjustments
- DIY-friendly install path with on-screen prompts
- Works with Alexa for voice control in a smart-home setup
Factors To Consider
- C-wire required, which rules out quick swaps in some older homes
- Touchscreen stays lit during use, so screen brightness matters in bedrooms
Who Should Grab It
Homeowners with a C-wire ready who want a familiar touchscreen experience plus Wi-Fi scheduling.
Another Choice May Suit
The Mysa Smart Thermostat fits a baseboard-heating household that specifically wants HomeKit, where the Sensi is the simpler whole-home pick.
The PRO1 T805 steps up to a noticeably larger 7 sq. in. blue backlit display, which matters more than it sounds in hallways and open living areas. It’s a 1H/1C conventional thermostat with 7-day, 5/1/1, or fully non-programmable modes, so you can opt out of scheduling entirely if you prefer.
Versus the T701, the T805 trades a smaller footprint for a much more readable screen. The glow-in-the-dark light button carries over, keeping late-night checks painless for anyone who doesn’t want to grab their phone first.
Bright Spots
- Extra-large 7 sq. in. blue backlit display readable from across the room
- Three scheduling modes give flexibility to skip programming entirely
- Glow-in-the-dark light button aids late-night navigation
- Conventional 1H/1C compatibility suits most standard HVAC equipment
Some Limits To Know
- No Wi-Fi or app control, so remote changes aren’t possible
- Larger face may crowd a small wall plate if you’re replacing a compact prior model
Right Fit For
Living areas, hallways, and main-floor rooms where a big display and simple programming beat smart features.
Reach For A Different Pick When
The Sensi Touch Smart Thermostat is the better swap for a smart-home household that wants a color touchscreen.
The 4th generation Nest Learning Thermostat is the model you set on the wall and let it watch your patterns for a couple of weeks. It builds its own schedule based on the temperatures you choose and when you choose them, and pairs here with a 2nd gen Nest Temperature Sensor so a specific room can lead the system.
Compared to the PRO1 T715 earlier, Nest trades hands-on scheduling for software that learns on your behalf. The Obsidian finish also makes it a design choice, useful if your thermostat sits in a visible spot like above a fireplace or in a main entry.
Benefits That Matter
- Learns preferences over time and adjusts the schedule automatically
- Bundled temperature sensor balances comfort toward the room you actually use
- Obsidian finish blends into modern and dark-themed interiors
- Monitors HVAC system health for early warnings about runtime issues
Potential Sticking Points
- Learning period can feel unpredictable in the first couple of weeks
- Sensor placement influences results, so it may need a small repositioning pass
Built With In Mind
Busy households that prefer the thermostat to do the schedule-building for them and want a striking on-wall look.
Swap It Out When
The PRO1 T715 fits better for a two-stage gas homeowner who wants fixed programming without cloud features.
The Silver edition of the 4th gen Nest is the same learning thermostat as the Obsidian version above, with a finish that pairs more naturally with lighter walls, brushed hardware, and contemporary kitchens. You still get the bundled 2nd gen Nest Temperature Sensor to steer comfort toward a specific room.
Versus the Mysa earlier, Nest is the better fit for central HVAC rather than high-voltage baseboards. The trade-off is dependency on cloud-driven scheduling, so the system needs a stable Wi-Fi connection to keep its smarts up to date.
What It Does Well
- Adaptive scheduling trims the manual tinkering that other thermostats demand
- Included temperature sensor helps balance uneven multi-room layouts
- Silver finish suits light, neutral, or modern farmhouse interiors
- System monitoring flags potential HVAC issues before they escalate
Where It Is Less Suited
- Smart features depend on a reliable home Wi-Fi connection
- Learning behavior can take a few weeks to settle into a steady rhythm
Who Should Grab It
Homeowners with central HVAC and a light-toned interior who want a learning thermostat with a softer finish.
Not Your Match When
The Mysa Smart Thermostat is the better pick for a HomeKit household running electric baseboard heat.
What To Weigh Before Choosing A HomeKit Thermostat
Start with your HVAC type, because the entire feature list hinges on it. Central air with a conventional furnace plays nicely with most wall thermostats, while electric baseboards and fan-forced heaters live in a high-voltage world that only certain models like the Mysa can safely handle. A heat pump system adds a second layer of stages and reversing-valve logic that simpler thermostats may not address.
C-wire status is the next decision gate. Many smart thermostats need a common wire for steady power, and older homes without one will need an adapter or a small wiring tweak before the install goes smoothly. For households that prefer no extra wiring, battery-powered models like several PRO1 T-series units remain a low-friction option.
Consider scheduling depth too. Fixed 7-day programming rewards consistent routines, while learning thermostats like the 4th gen Nest build the schedule on your behalf. Homes with shifting weekly patterns often get more value from a learning approach, while steady commuters may prefer the predictability of a manual program.
Finally, weigh voice and ecosystem fit. HomeKit households get the most out of thermostats that expose themselves to Siri and the Home app, which is where Mysa and several smart picks earn their keep. Households already running Alexa or Google may prefer thermostats that lean into those routines instead.
Smart Considerations Before You Buy
Common Slip Ups Shoppers Hit
A frequent mistake is grabbing a HomeKit-friendly thermostat without checking the wiring first, especially the C-wire. Many smart models simply won’t power up reliably without it, and the install can stall mid-project.
Another trap is assuming any smart thermostat works with electric baseboards. Most mainstream smart units are designed for low-voltage central systems, so a high-voltage specialty like the Mysa is required for those homes.
What The Higher Tier Buys
Stepping up to a learning or sensor-equipped thermostat usually pays off when your routine shifts often or your home has hot and cold spots that one wall sensor can’t capture. The 4th gen Nest and Mysa both illustrate how extra hardware and software turn a static setpoint into responsive comfort.
For homes with simple, predictable schedules, a mid-tier programmable model often delivers most of the comfort without ongoing subscription-like complexity. The honest read is that the upgrade is worth it when your time and uneven rooms are both in short supply.
