Rheem 4 Ton Variable Speed Air Handler 21" Wide W/ R-454B Sensor

RH2VY4821STACNJ - Endeavor® Line Air Handler

Key Features:

• Constant CFM Motor: When paired with the EcoNet® Smart Thermostat, the motor gradually adjusts from low capacity to 100% to meet comfort requirements, allowing for optimal humidity control, quieter sound levels, and year-round energy savings. With a 24V two-stage thermostat, the air handler operates in two speeds to match airflow with the outdoor unit.

• Quieter Operation: Two-stage operation and variable speed airflow technology, combined with sturdy cabinet construction featuring 1.0 inch of foil-faced insulation, provide quieter sound characteristics.

• PlusOne® Diagnostics: Built-in EcoNet® and Bluetooth® technology, accessible via the Rheem Contractor and EcoNet® Apps, make monitoring, troubleshooting, and repairing the product easier than ever before.

• Dip Switch-Free Installation Commissioning via Bluetooth® Technology: Allows for seamless final installation without DIP switch configuration using the Rheem Contractor App.

• EcoNet® Enabled Air Handler: The latest sensor technology and the EcoNet® monitoring system provide a new level of protection, control, and energy savings. Homeowners can enjoy on-the-go control and receive system alerts via the EcoNet® Smart Thermostat and EcoNet® App.

• Aluminum Indoor Coil Design: Constructed of aluminum fins bonded to internally grooved aluminum tubing, offering enhanced corrosion resistance.

• Versatile 4-Way Convertible Compact Design: Allows for upflow, downflow, horizontal left, and horizontal right applications, even in the smallest of spaces.

• Rugged Steel, Compact Cabinet Construction: Designed for added strength and versatility.

• Less than 2% Cabinet Air Leakage at 1-inch H₂O: Tested in accordance with ASHRAE Standard 193 to ensure minimal air leakage.

• Designing for Sustainability with Low GWP: Utilizes R-454B refrigerant, which has a global warming potential (GWP) limit of 700, resulting in a 78% lower GWP than previous-generation refrigerants, aligning with 2025 Environmental Protection Agency (EPA) requirements.

• PlusOne® Refrigerant Detection System™: An integrated, patented design featuring the A2L sensor and mitigation board, offering easier commissioning with a single component and simplified wiring configuration. It is compatible with any 24V thermostat application and provides system protection by automatically pausing outdoor unit operation if excess refrigerant is detected.
