When Rheem and Ruud updated their air handler control architecture for SEER2 compliance, the updated control board became incompatible with legacy heat strip wiring configurations. This adapter bridges that gap, allowing technicians to retain existing heat strip assemblies rather than replacing the entire heating section. It is installed by licensed HVAC technicians during system upgrades or equipment changeouts where the air handler is being replaced but the existing heat strips are being kept in service.\u003c\/p\u003e\u003cp\u003eThis adapter is intended for residential HVAC applications where a new SEER2-compliant air handler is being paired with legacy RXBH-1724 or WRX series heat strips. It is a practical solution during retrofit installations where replacing the heat strips is not cost-effective or practical. New air handler models RF1PZ, RF2TZ, and RH1PZ are confirmed compatible with this adapter. Technicians should verify the air handler model before ordering to ensure correct fitment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBridges new SEER2 air handler control boards to legacy heat strip wiring configurations\u003c\/li\u003e\n\u003cli\u003eCompatible with RXBH-1724 and WRX series heat strips\u003c\/li\u003e\n\u003cli\u003eSupports new air handler models RF1PZ, RF2TZ, and RH1PZ\u003c\/li\u003e\n\u003cli\u003eNot compatible with RH3V or RHMV models — those systems require a new heat strip assembly\u003c\/li\u003e\n\u003cli\u003eSimplifies retrofit upgrades by eliminating the need to replace functional legacy heat strips\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with new Rheem and Ruud air handler models RF1PZ, RF2TZ, and RH1PZ when used with legacy RXBH-1724 or WRX series heat strips.

Disconnect power to the air handler at the breaker before beginning any work on the control board or heat strip wiring. Confirm the air handler model is on the compatibility list prior to installation, as using this adapter with an incompatible model will not resolve the wiring mismatch. Follow all applicable NEC requirements for low-voltage and line-voltage connections within the air handler cabinet.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction\u003c\/strong\u003e: SEER2 air handler to legacy heat strip adapter board\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Heat Strips\u003c\/strong\u003e: RXBH-1724, WRX series\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Air Handler Models\u003c\/strong\u003e: RF1PZ, RF2TZ, RH1PZ\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncompatible Models\u003c\/strong\u003e: RH3V, RHMV\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: RUUD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 45-106229-04\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RUUD","offers":[{"title":"Default Title","offer_id":51283903021362,"sku":"45-106229-04","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309277769.png?v=1781062844","url":"https:\/\/voomisupply.com\/products\/ruud-45-106229-04-seer2-air-handler-adapter-board","provider":"Voomi Supply","version":"1.0","type":"link"}
