As a direct upgrade for the legacy 950-8801 board, this \u003cstrong\u003e115VAC circuit board\u003c\/strong\u003e is designed to interface with almost any burner control circuit, providing critical safety interlocks for oil and gas-fired equipment. This \u003cstrong\u003epower venter control board\u003c\/strong\u003e features adjustable pre-purge and post-purge settings via onboard dip switches, allowing technicians to fine-tune venting cycles and prevent draft-induced short cycling. The integrated \u003cstrong\u003ediagnostic LED indicators\u003c\/strong\u003e provide immediate status feedback, simplifying troubleshooting for fan prover status and call-for-heat signals. Built for durability in high-demand mechanical rooms, the 950-8804 includes a 10-second prover switch delay to stabilize the system against wind gusts. Whether you are servicing an \u003cstrong\u003eSS1, SS2, or HS-series\u003c\/strong\u003e unit, this \u003cstrong\u003edraft inducer replacement board\u003c\/strong\u003e ensures the tight electrical tolerances required for reliable venting and appliance safety.\u003c\/p\u003e\n\n\u003cstrong\u003eKey Benefits:\u003c\/strong\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUniversal Compatibility:\u003c\/strong\u003e Serves as the primary \u003cstrong\u003ereplacement UC1 control board\u003c\/strong\u003e for the full line of Tjernlund power venters and draft inducers.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnhanced Troubleshooting:\u003c\/strong\u003e Features five \u003cstrong\u003ediagnostic LEDs\u003c\/strong\u003e (Amber, Green, Red) to pinpoint faults in the safety circuit or call signals instantly.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eField Adjustable:\u003c\/strong\u003e Onboard dip switches allow for precise \u003cstrong\u003epre-purge and post-purge timing\u003c\/strong\u003e to match specific appliance requirements.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eImproved System Stability:\u003c\/strong\u003e Built-in 10-second delay for the fan prover switch helps avoid nuisance shutdowns caused by transient wind pressure.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSimple Installation:\u003c\/strong\u003e Designed for rapid field replacement with compatible \u003cstrong\u003emounting hardware\u003c\/strong\u003e and clear terminal labeling for 115V or 24V calls.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cstrong\u003eCommon Questions:\u003c\/strong\u003e\n\u003cp\u003e\u003cstrong\u003eIs the 950-8804 compatible with older power venters?\u003c\/strong\u003e\u003cbr\u003e\nYes, this \u003cstrong\u003euniversal control board\u003c\/strong\u003e is the standard replacement for all past year models of Tjernlund draft inducers and power venters, including the SS1, SS2, and HS series.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat do the flashing red LEDs on the board indicate?\u003c\/strong\u003e\u003cbr\u003e\nThe red \u003cstrong\u003estatus\/fault indicator\u003c\/strong\u003e flashes specific codes to diagnose issues such as fan prover failures or burner circuit interruptions, allowing for faster field resolution without guesswork.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCan this board handle different thermostat voltages?\u003c\/strong\u003e\u003cbr\u003e\nThe board supports both 24VAC and 115VAC intercepted calls.
