47°F = 8.3°C; 17°F = −8.3°C; 5°F = −15°C. COP is dimensionless. These are reported rating points, not a prediction of a particular home’s heat demand or operating limit.

Matched systems

Each row is one source record. The component column distinguishes listed combinations from outdoor-model ratings without an indoor configuration.
