It manages the burner sequencing cycle  -  including pre-purge, ignition, pilot flame proving, and post-purge  -  while the built-in VPS verifies gas valve integrity before and after each burner firing. This level of safety logic makes it a standard choice for licensed burner technicians and combustion engineers working on forced-draft and induced-draft burner systems.\u003c\/p\u003e\u003cp\u003eThe RM7898A2000 is suited for commercial and industrial burner installations where safety shutoff verification is required by code or by the equipment manufacturer. The VPS function satisfies regulatory requirements in jurisdictions that mandate valve proving on gas-fired equipment, making this control appropriate for boiler rooms, process heaters, and similar applications where continuous or cycling burner operation demands rigorous flame-safety oversight.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eOn-off burner sequencing with integrated Valve Proving System (VPS)\u003c\/li\u003e\n\u003cli\u003eAutomatic pre-purge and post-purge cycle management\u003c\/li\u003e\n\u003cli\u003eFlame-safety lockout with manual reset for fail-safe operation\u003c\/li\u003e\n\u003cli\u003eDesigned for forced-draft and induced-draft commercial burner systems\u003c\/li\u003e\n\u003cli\u003eSatisfies valve-proving code requirements in applicable jurisdictions\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement primary burner control for commercial and industrial gas-fired burner systems requiring on-off control with valve proving functionality.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed burner technician or combustion engineer familiar with flame-safety controls and applicable codes including NFPA 85 and NFPA 86. Shut off all gas supply and disconnect electrical power to the burner system before removing the existing control. Follow the burner manufacturer's wiring diagram precisely when connecting the RM7898A2000; do not rely on the existing wiring arrangement without verification. After installation, perform a full burner startup sequence and confirm VPS operation and safety lockout function before returning the system to service.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eControl Type\u003c\/strong\u003e: On-Off Primary Burner Control\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eValve Proving System\u003c\/strong\u003e: Integrated VPS\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: Honeywell\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: RM7898A2000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HONEYWELL","offers":[{"title":"Default Title","offer_id":67595099504946,"sku":"RM7898A2000","price":1318.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/43ab1e04c091bbdea43fdea16984d17e.jpg?v=1790423332","url":"https:\/\/voomisupply.com\/products\/honeywell-rm7898a2000-on-off-primary-control-vps","provider":"Voomi Supply","version":"1.0","type":"link"}
