Copeland · ST76
Ready to buy
The retained reference is $209.99 current U.S. MSRP. ST76W is a cosmetic color variant; room sensors, professional wiring and HVAC accessories are separate. Verify every terminal, transformer, stage, auxiliary transition, local control, account transfer and return or installer-service term before purchase.
Current market
Each line carries its own check date because price, software, specifications, and product cycle do not age at the same speed.
ST76W is a cosmetic color variant; room sensors, professional wiring and HVAC accessories are separate. Confirm current stock, authorized U.S. seller, included hardware, tax, shipping, return rights and installation before paying.
Touch 2 is defended for complex conventional terminal counts and room sensing when a C-wire is available and proprietary communicating control is not required.

What changed
Older observations stay in the ledger when the current view changes. That lets a buyer tell the difference between an old complaint, an active issue, and a problem that was corrected.
Sensi Touch 2 Smart Thermostat was checked against exact identity and support, current U.S. price, topology, stages, power, heat-pump, sensors, app, offline, demand-response, installation, service and outcome boundaries, independent decision evidence and bounded owner or installer reports.
Each amount stays tied to its source and capture date. Conflicting prices remain visible until the seller resolves them.

Owner experience
Owner and installer discussion returns to c-wire setup, high-stage configuration, sensor priorities, app behavior and service rather than a universal comfort, savings or reliability result.
These are self-reported experiences from different HVAC equipment, wiring, transformers, zones, homes, climates, setpoints, tariffs, networks, firmware, apps, utility programs, installers and maintenance histories. They identify checks to run and do not establish comfort, savings, temperature accuracy, air quality, fault diagnosis, safety, freeze protection, reliability or failure rates.Owners and technicians discuss C-wire setup, sensors, app behavior, heat-pump staging and service. Reports cannot establish a population failure or savings rate.
Verify each relay stage at the equipment, then compare thermostat and room-sensor readings before activating occupancy priorities.

Copeland identifies ST76 as a C-wire-powered conventional thermostat with a color display, broad 4H/2C heat-pump support and optional Sensi room sensors.

Conventional 24 VAC control for gas, oil, electric, boiler and heat-pump equipment; not for proprietary communicating or line-voltage systems Supports up to 2 heat/2 cool conventional and up to 4 heat/2 cool heat pump within the exact terminal map Auxiliary, emergency and dual-fuel logic require correct stage, fuel and lockout choices; outside data or a stage count alone does not validate dual fuel A C-wire is required; confirm transformer common and do not use an unsupported external transformer across equipment circuits Optional Sensi room sensors can prioritize or average rooms and detect occupancy under supported modes; they do not control dampers or repair airflow imbalance
Sensi app, account, Wi-Fi, geofencing and integrations process device and household data; Copeland states it does not sell personal information used for targeting, subject to its full policy The touchscreen and stored schedule retain core control without internet, while remote changes, geofence, reports, weather and integrations stop Three-year limited warranty terms apply. Privacy positioning, room sensors and high stage count cannot guarantee comfort, savings, air balance or equipment protection
Certified connected thermostats must retain basic thermostat operation without service-provider connectivity, support schedules and report energy-use information; certification is not a household comfort or savings guarantee.
EPA directs buyers to match HVAC type, voltage, wires, variable speed, stages and zoning before purchase and notes that line-voltage and complex systems often require specialized controls or professional installation.
Heat-pump performance depends on the complete equipment and controls; thermostat stage or app labels do not establish capacity, auxiliary-heat economics, dual-fuel operation or delivered comfort.
FTC consumer guidance covers router security, unique passwords, updates and privacy settings for connected devices; cloud convenience does not remove household security and access duties.
An experienced tool and installation publication evaluates the exact model's display, installation, sensors, app and professional-use fit.
Owners and technicians discuss C-wire setup, sensors, app behavior, heat-pump staging and service. Reports cannot establish a population failure or savings rate.
Smart Thermostat Premium is the premium conventional 24 v room-sensing control defended alternative at $259.99 current U.S. direct price.
Connected Control BCC110 is the high-stage conventional hvac-professional control defended alternative at $189 current U.S. retail price.
Manufacturer identity, exact product or support documentation, current U.S. price, independent decision evidence and bounded owner or installer evidence were checked on August 19, 2026. This desk covers complete current U.S.-supported residential thermostat and HVAC-control systems where conventional low-voltage relays, proprietary communicating control, line-voltage electric heat, radiant-floor control or mini-split infrared retrofit materially changes the decision. It excludes bare sensors, faceplates, cosmetic finishes, multipacks, dealer software licenses, unsupported prior generations, portable-heater controls and smoke or carbon-monoxide life-safety alarms. Voltage, transformer, terminals, stages, heat-pump, auxiliary, emergency-heat, dual-fuel, proprietary-bus, accessory, zoning and sensor limits are exact-model facts. A room sensor can influence one equipment zone without creating duct zoning. Mini-split IR controllers can miss commands or lose state when the native remote is used and cannot override shared-outdoor-unit mode limits. Local wall control and stored schedules differ from app, voice, weather, geofence, history, firmware and demand-response services that require accounts, cloud and connectivity. Demand-response enrollment is voluntary and utility-specific. Turn off equipment power and use a qualified HVAC technician or electrician for uncertain low-voltage, communicating, dual-transformer, line-voltage, wet-area or multi-equipment work. Compressor delays, balance points, stage timing, O/B, fan, fuel and dual-fuel settings must match the equipment manual. Alerts, temperature, humidity, TVOC and CO2-equivalent readings are not equipment diagnosis, source identification, health diagnosis or safety clearance and do not replace smoke and CO alarms. No thermostat or control guarantees comfort, even rooms, energy savings, utility rewards, freeze protection, equipment life, fault prevention or uninterrupted service.
