Smart Thermostats / Copeland
Sensi Touch 2 (ST76)
Deep multi-stage and heat-pump wiring for under $200, with no Matter and no Apple Home.
Overall score 6/10
Pros
- + 4H/2C heat pump staging plus humidifier and dehumidifier terminals — genuinely serious HVAC coverage for under $200
- + 3-year warranty and a published privacy stance that no other brand here makes explicit
- + Street price has settled around $189 against a $209.99 list, and it periodically drops much further
- + Real multi-stage and dual-fuel handling that the similarly priced Nest Thermostat and ecobee Essential do not offer
Cons
- − No Matter and no Apple HomeKit — the Touch 2 dropped the HomeKit support the original Sensi Touch had
- − C wire required and the C-Wire Kit is a ~$28 extra, where ecobee includes an equivalent kit free
- − Sensi Room Sensors are $40 each, sold separately, and detect temperature and humidity only — no occupancy
- − No decorative trim plate in the box, so old paint outlines and screw holes show
- − Copeland does not publish how many room sensors can pair, which makes planning a multi-room setup guesswork
Sensi Touch 2 (ST76) review: what the specs say
Deep multi-stage and heat-pump wiring for under $200, with no Matter and no Apple Home. At $189, Copeland's 2022 model sits in the middle of the range — the smart Thermostats we compare run from $79 to $259.99. It scores 6.0/10 overall, calculated from published specifications across 8 categories rather than from a subjective impression.
Its strongest showing is HVAC Coverage at 9.0/10 — stages of heating and cooling, heat pump and auxiliary heat handling, and humidifier / dehumidifier / ventilator terminals. The weakest is C-Wire Freedom at 2.0/10, which is the trade-off to weigh before buying: if that is the specification you care about most, one of the alternatives below will serve you better.
Worth knowing before you buy: no Matter and no Apple HomeKit — the Touch 2 dropped the HomeKit support the original Sensi Touch had; and c wire required and the C-Wire Kit is a ~$28 extra, where ecobee includes an equivalent kit free. Every specification on this page comes from Copeland's own documentation or a verified retail listing — where a figure is not published, the table says so rather than estimating it.

Full Specifications
| System Voltage | Low voltage 24VAC — gas, oil, electric, heat pump, boilers. Not for 120/240V line-voltage heat |
| C-Wire Required | Yes. Copeland's spec sheet requires 20-30VAC between RH/RC and C, and every retail listing is labelled 'C-Wire Required' |
| Adapter / Power Kit Included | No — the Sensi C-Wire Kit is a separate purchase at roughly $28 |
| Heating & Cooling Stages | 1H/1C, 2H/2C multi-stage, and up to 4H/2C on heat pumps |
| Heat Pump & Aux Heat | Yes — up to 4 heat and 2 cool including auxiliary stages, the widest heat-pump staging here alongside the ecobee Premium |
| Humidifier / Ventilator Terminals | ACC+/ACC- terminals drive a humidifier or dehumidifier, with a humidify range of 5-50% RH and dehumidify 40-95% RH |
| Remote Sensors | Sensi Room Sensors at about $40 each, sold separately. Copeland states only the Touch 2 (ST76 / 1F96U series) supports them and does not publish a maximum count |
