| 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 |
