What doesn’t work? The Sensi Touch can’t control high-voltage systems like electric baseboard heaters. It’s not designed for proprietary systems that require specific manufacturer thermostats. Multi-zone systems that use a single thermostat won’t function properly either.

The C-wire question creates the most confusion during compatibility checks. Many modern HVAC systems include this common wire that provides continuous power. The Sensi Touch can operate without a C-wire in many installations. However, some configurations absolutely require one for stable operation.

Emerson provides an online compatibility checker tool. You input information about your current thermostat and system. The tool indicates whether the Sensi Touch will work for you. This free resource prevents incompatible purchases.
