| Cooling capacity · BTU/h | 45,000–48,000 | 190 / 190 |
| Heating capacity at 47°F / 8.3°C · BTU/h | 42,500–52,000 | 190 / 190 |
| Heating capacity at 17°F / −8.3°C · BTU/h | 34,200–44,500 | 190 / 190 |
| Heating capacity at 5°F / −15°C · BTU/h | 29,000–39,500 | 190 / 190 |
| COP at 5°F / −15°C | 1.88–2.2 | 190 / 190 |
| Equipment / loop type | HP - Split System | 190 / 190 |
| Refrigerant / source-reported GWP | R-454B (GWP:470 | Lower GWP) | 190 / 190 |
| Compressor staging | Continuously variable | 190 / 190 |
| Connected capability | No | 190 / 190 |
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.
