Heat Pump Heating Performance

The TWA090K4AAA**BS01 provides heat pump operation for year-round heating and cooling. When matched with compatible indoor equipment, the heat pump condenser can provide primary heating operation, with supplemental electric heat available where supported by the selected indoor equipment. Actual heating capacity and system efficiency depend on the certified outdoor and indoor equipment combination.

87,000 BTU/h Cooling Capacity

The TWA090K4AAA**BS01 is a 7.5-ton nominal heat pump condenser with 87,000 BTU/h nominal cooling capacity. Trane's Odyssey product documentation identifies the TWA090K4A as a single-circuit heat pump configuration. The published Odyssey application information identifies a minimum step of 5 tons for the single-circuit TWA090 configuration.

R-454B Refrigerant & Efficient System Operation

The TWA090K4AAA**BS01 uses R-454B refrigerant for its heat pump circuit. R-454B is an A2L refrigerant, so installation, service, refrigerant handling, and piping procedures must follow the applicable Trane documentation and current codes. Trane provides model-specific requirements for refrigerant piping, charging, and installation of Odyssey R-454B equipment.

460V Three-Phase Split-System Installation Design

The split-system configuration separates the outdoor TWA090 heat pump condenser from the compatible indoor air handler or coil assembly. Trane's published Odyssey application information identifies the single-circuit TWA090 configuration with a 1-1/8-inch gas-line diameter for horizontal and downflow applications. Refrigerant piping must be sized and installed according to the applicable Trane Odyssey application and installation documentation.

Controls & Comfort

The TWA090K4AAA**BS01 supports Trane Symbio™ 700 controls for compatible Odyssey system configurations. Depending on the matched indoor equipment and selected controls, the system can support conventional thermostat, zone-sensor, and communicating control arrangements. Trane documentation also provides configurations for pairing a TWA heat pump condenser with compatible constant-volume or two-speed/SZVAV air handlers. Actual control functionality and supplemental heat operation depend on the selected indoor equipment and control configuration.

Commercial Applications

The Trane Odyssey TWA090K4AAA**BS01 is designed for commercial split-system applications requiring approximately 7.5 tons of heat pump capacity. Its 460V three-phase electrical configuration, single refrigeration circuit, and compatibility with Odyssey indoor equipment make it suitable for commercial buildings where a separate outdoor heat pump condenser and indoor air-handling system are preferred.

Service & Maintenance

The Odyssey split-system platform is designed with standardized cabinets and components to support installation and service. The TWA090 platform also supports application-specific accessories for isolation, service, low-ambient operation, communications, and other installation requirements. Accessory selection should be based on the specific unit configuration and applicable Trane documentation.

Warranty

Warranty coverage for the TWA090K4AAA**BS01 should be confirmed using the current Trane Odyssey Limited Warranty documentation applicable to the equipment, installation, registration status, and application. Trane's product documentation directs users to the applicable Product Data/Ratings, Installer Guides, and Limited Warranty Handbooks for complete warranty information.
