Description
The Daikin Oterra RXF12AXVJU outdoor condenser paired with the FTKF12AXVJU indoor wall‑mount unit delivers 12,000 BTU cooling and 13,500 BTU heating capacity. This single‑zone ductless heat pump uses R‑32 refrigerant, achieving 21 SEER2, 12.5 EER2, and 10.2 HSPF2—certified by AHRI. Utilizing inverter-driven, variable‑speed swing compressor technology, it operates efficiently in cooling up to 115 °F DB (extended to –4 °F with optional wind baffle) and provides heating down to 5 °F WB. Sized compactly and mounted on a wall, this system meets the needs of homeowners, contractors, and property managers looking for high-performance, energy-efficient zoned comfort.
Performance
Featuring a hermetic swing compressor and fin‑tube coil design, the Oterra system offers precise capacity modulation and up to 30 % greater energy savings over fixed-speed ducted units. Maximum airflow reaches approximately 1,051 CFM outdoors and up to 436 CFM indoors on high setting, delivering strong circulation with reduced cycling losses . With a rated COP of 3.8 in heating and total system input near 960 W cooling/1,038 W heating, efficiency is sustained across a wide range of conditions. Factory charge is 1.65 lbs of R‑32, accommodating up to 65 ft of piping and 49 ft of vertical lift.
Smart Features
Connectivity is seamless with the Air-to-Wireless DKN Cloud Adapter, enabling remote control, scheduling, and diagnostics via smartphone. Included support for backlit wireless remote and optional wired remotes allows flexible zoning and user level control . Self-diagnostic and auto-changeover functions simplify management, while eco+ and dry modes optimize performance. The Oterra unit is compatible with select third‑party smart thermostats, though built‑in controls provide comprehensive functionality for both residential and contractor use.
Comfort & Noise
Engineered for whisper‑quiet operation, the indoor unit runs as low as 19 dBA in quiet mode, while the outdoor unit operates around 49 dBA on high speed. Indoor airflow ranges from 247 CFM (quiet) to 436 CFM (high), promoting gentle yet effective air distribution . Comfort-enhancing features include Blue Fin hydrophilic coil coating for quicker condensate drainage and automatic defrost and quick-warming functions to maintain performance in cold environments. Overall, these innovations deliver consistent, comfortable climate control in living and workspaces.
Use Case Fit
This 1‑ton system is ideal for residential use in spaces between 400–600 ft², as well as enhancement zones in multi‑family, small commercial, or retrofit applications. Its wide temperature operating range—from –4 °F to 115 °F in cooling and 5 °F to 65 °F in heating—makes it suitable for diverse regional climates, including hot, humid summers and cold winters. The slim wall-mounted profile suits retrofits, sunrooms, garages, and offices with limited floor or ceiling space. Contractors and property managers benefit from its modular nature, allowing phased installations and custom zoning strategies.
Value & Reliability
Manufactured by Daikin, a global HVAC leader, the Oterra series features robust construction with anti-corrosion coating and a multi-hole outdoor drain pan to prevent ice buildup. Compressor and fan motors are service-friendly and maintainable, supported by straightforward diagnostics, direct-access panels, and easily detachable components . The inverter technology prolongs lifecycle and ensures stable operation; OEM support and rebate readiness enhance value for wholesale partners and commercial specifiers.
