Single-Zone & 115V Compatibility
The 115V model is ideal for residential retrofits or spaces where only 115-volt supply is available (e.g. older homes, additions).
Inverter / Variable Speed Technology
The OTERRA 115V modulates its compressor speed based on load demand, enhancing efficiency, reducing cycling, and improving comfort.
R-32 Refrigerant
Uses modern R-32 refrigerant, which provides better performance and lower global warming potential compared to older refrigerants.

It is designed to operate quietly, with sound mitigation features and indoor quiet / sleep modes.

No—since it’s ductless, only refrigerant lines, wiring, and drain are needed.

Typically a 12-year parts limited warranty (with registration and proper installation).

At least annually to maintain efficiency, system health, and warranty eligibility.
