Indoor configuration coverage

3 of 15 EPA records for this model do not list individual indoor units. EPA’s reporting template permits this for multi-split systems. Manufacturer-documented kits are identified on their individual source pages. These rows identify an outdoor-model rating and do not establish a complete matched system or compatibility with an arbitrary indoor unit.

Heating performance & equipment details

Ranges include the 15 published source records for this model. Values in different rows may describe different configurations. Open an individual record to compare values from the same test configuration.

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.

Source ratings & listed systems

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