They feature leak economizers (AMCA 511 certified w/FDD) with dry bulb, single enthalpy, or dual enthalpy sensing, CO2 sensor for demand control ventilation, manual or motorized damper, barometric relief, constant volume power exhaust, and modulating power exhaust.

Thermostat compatibility: Compatible with most thermostats.

Replacement parts compatibility: Shares replacement parts with other models.

Additional features: Choice RTUs can be optioned from the factory to use electric heat instead of gas combustion, which can help to reduce harmful CO2 gas emissions. Other helpful features include independent circuits to help avoid full unit shutdowns and a lead-lag compensator for exceptional reliability. An optional mobile access portal with Wi-Fi hotspot gives contactors easier access to commissioning, configuration, and maintenance tools simply by using a smart device.

Warranty information: Standard five-year compressor limited warranty and one-year parts limited warranty with product registration. Extended warranties are available.

Special installation requirements: Choice RTUs have a variety of install-friendly features that create flexibility for a range of applications. The unit's footprint fits approximately 70% of competitive installed bases without the need for costly transition curbs. Its direct replacement footprint and lightweight design offer ease of installation for both new product and retrofit applications. Choice heat pump platforms are up to 20% lighter than existing TempMaster models.

With X-Vane fan technology

Noise-reduction features: Fully insulated cabinet, isolated scroll compressors, and balanced indoor/outdoor fan systems. Indoor fan uses X-Vane/Vane Axial fan design with built-in, ramp-up speed technology to soften sound during startup. Lightweight, high-impact, composite fan blade on the outdoor fan system minimizes sound. X-Vane units have an acoustic dBA of 79 (the dial tone on a phone has a dBA of 80).

Thermostat compatibility: Compatible with most thermostats.

Replacement parts compatibility: Shares replacement parts with other models.

With X-Vane fan technology

Serviceability features: New unit control board puts all connections and troubleshooting points in one convenient location. Most low voltage connections can be made to the same easy-access board. RHV rooftops have high- and low-pressure switches, a new mixed air pressure switch, a filter drier, and 2-inch filters standard.

Thermostat compatibility: Compatible with most thermostats.

Replacement parts compatibility: Shares replacement parts with other models.

Warranty information: Five-year limited warranty on compressor and one-year limited warranty on all other parts. Up to five-year extended parts warranty available. See warranty certificate for complete details and restrictions.

Serviceability features: Built on the Ascend chiller platform, ACX leverages Trane controls knowledge and expertise to provide consistent quality and reliability supported by Trane's major distribution and local office support. The common platform facilitates maintenance, servicing, and component sourcing.

Noise-reduction features: Available compressor factory installed acoustical treatment as well as an optional noise reduction request to allow for a lower sound signature during nighttime operation. Maintenance-free, long-life EC fan motors reduce sound at part loads.

IAQ equipment supported: Manufacturer did not specify.

Thermostat compatibility: Manufacturer did not specify.

Replacement parts compatibility: Shares replacement parts with other models.

Additional features: Ascend model ACX offers high efficiency for heating and cooling performance as a result of its boiler free heating. Intermediate discharge valves and variable volume ratio technology enhance system efficiency while maintenance-free, long-life EC fan motors improve efficiency and reduce sound at part loads. Dual electronic expansion valves (one for cooling and one for heating) are built-in metering devices for refrigerant, which ensure proper amount of refrigerant to provide reliable operation in different modes.

Warranty information: Standard warranty is full parts for 12 months from startup or 18 months from shipment, whichever comes first.

Special installation requirements: The unit's Symbio 800 controller features open standard protocol, enabling seamless and secure integration with building automation systems, leveraging secure remote IP connectivity (BACnet, Modbus) and optional Trane Air-Fi wireless technology and LonTalk communication protocols for simplified equipment monitoring and management. Post-installation, Symbio 800 can connect with Trane energy analysis and 24/7 system monitoring services to ensure Trane chillers are continuously optimized for efficiency and uptime.

Serviceability features: These new units (12.5 to 25 tons) have been designed to reduce complexity and improve serviceability. The new Symbio 700 unit controller includes an intuitive onboard interface and Bluetooth-enabled service and installation app that clearly displays system alarms and diagnostics, making troubleshooting quick and easy. Plus, there are no fan belts to adjust, filters are easy to replace, and every unit has toolless coil guards and hinged access to the control panels.

Noise-reduction features: Manufacturer did not specify.

IAQ equipment supported: New units provide solution to address all four pillars of indoor air quality: dilution is accomplished via ventilation (economizers); exhaust is accomplished via building pressure relief (barometric relief/power exhaust); contain is accomplished via humidity control (modulating hot gas reheat); and clean is accomplished via filtration (MERV8 or MERV13 filters).

Thermostat compatibility: Compatible with most thermostats.

Replacement parts compatibility: Some shared parts and some unique parts. Shares replacement parts with other models.

Additional features: Precedent delivers a complete offering of standard efficiency, 3- to 25-ton, light commercial, packaged, rooftop heat pumps units with the addition of the new 17.5- and 25-ton units. The redesigned heat pumps include the new Symbio 700 unit controller that optimizes performance, improves serviceability, and provides unit connectivity. The new heat pumps also have longer warranty coverage, standard coil guards, and additional options including single and multi-zone VAV and modulating hot gas reheat.

Warranty information: Standard limited warranties include three-year parts and controls and five-year compressor. Dual fuel/hybrid systems also include 10-year aluminized heat exchanger and 15-year stainless steel heat exchanger.

Special installation requirements: New models arrive ready to install — no adapter curb is needed for nearly all replacements. Units are convertible — shipped in the downflow configuration and can easily be converted to horizontal. The controller setup and configuration can be completed using the onboard user interface or the Symbio service and installation app that connects directly via Bluetooth and provides guided startup tasks.
