This \u003cstrong\u003eadjustable 1-to-10 minute timer relay\u003c\/strong\u003e serves as a direct replacement for legacy models 950-1060 (24 VAC) and 950-1065 (115 VAC), offering flexible field integration for \u003cstrong\u003eHST-series side wall power venters\u003c\/strong\u003e, including HST-J, HST-1, and HST-2 units. Built for versatility, the \u003cstrong\u003e24\/115 VAC timer relay\u003c\/strong\u003e handles dual-voltage control inputs, allowing contractors to standardize on a single part for both gas and oil-fired applications. Its non-polarity sensitive inputs simplify wiring, though continuous 115V power to terminals L1 and L2 is required for post-purge operation. Designed for high-duty cycles, this heavy-duty \u003cstrong\u003eHVAC draft inducer timer\u003c\/strong\u003e features a rugged cube relay housing and precision adjustment pot for exact timing calibration, ensuring code-compliant venting performance and preventing nozzle drip odor in oil systems.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eKey Benefits:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBroad Compatibility:\u003c\/strong\u003e Functions as a universal replacement for \u003cstrong\u003eTjernlund power venter\u003c\/strong\u003e controls, specifically engineered for HST, SS2, and GPAK-1T models.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFlexible Voltage Support:\u003c\/strong\u003e Accepts \u003cstrong\u003e24VAC or 115VAC control signals\u003c\/strong\u003e, making it suitable for both modern electronic ignition systems and older mechanical controls.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePrecision Safety:\u003c\/strong\u003e Maintains post-purge venting for 1 to 10 minutes to protect sensitive components from flue gas condensation and heat soak.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTechnical Reliability:\u003c\/strong\u003e Features an \u003cstrong\u003eOEM-spec cube relay\u003c\/strong\u003e design rated for 1\/4 H.P. at 120 VAC, ensuring robust motor switching in demanding venting environments.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eCommon Questions:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCan this relay be used on non-Tjernlund venting systems?\u003c\/strong\u003e While designed for Tjernlund HST series, this \u003cstrong\u003eadjustable post-purge timer\u003c\/strong\u003e is compatible with most inducer motor circuits requiring a timed-off delay, provided the load does not exceed 1\/4 H.P.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eHow do you adjust the post-purge duration?\u003c\/strong\u003e The timing is calibrated via a top-mounted adjustment screw.
