Heat sequencer relays are used to stage electric heating elements in sequence, preventing simultaneous full-load draws that can trip breakers or stress electrical components. This relay is an OEM replacement part built to factory specifications. It is typically installed by licensed HVAC technicians during routine service or component replacement on packaged heating and cooling units. At 0.1 pounds and a compact 2 x 2 x 2 inch footprint, it fits within tight equipment compartments without modification.\u003c\/p\u003e\n\u003cp\u003eThis relay is suited for residential and light commercial packaged units where staged electric heat is used. It operates on a 24-volt control circuit, making it compatible with standard low-voltage thermostat wiring configurations common in packaged rooftop and ground-level HVAC equipment. Confirmed compatible units include the DDUC-T036N050A, D3CG120N16525, and D2CG120N20025B. Additional compatible models may apply  -  consult the manufacturer fit guide for a complete list.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e24-volt control circuit for compatibility with standard low-voltage thermostat wiring\u003c\/li\u003e\n  \u003cli\u003eSequences electric heating elements to prevent simultaneous full-load draw\u003c\/li\u003e\n  \u003cli\u003eOEM replacement part built to factory specifications\u003c\/li\u003e\n  \u003cli\u003eCompact 2 x 2 x 2 inch form factor fits space-constrained equipment compartments\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.1 pounds for easy handling during installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eConfirmed compatible with YORK packaged units including the DDUC-T036N050A, D3CG120N16525, and D2CG120N20025B.

Disconnect and lock out all power to the unit before removing the existing relay or handling any wiring. Follow NEC guidelines for low-voltage control wiring when reconnecting the 24-volt circuit. Verify that the replacement relay matches the control voltage and circuit configuration of the original before energizing the system.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eControl Voltage\u003c\/strong\u003e: 24 volts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: YORK\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 2420000000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"YORK","offers":[{"title":"Default Title","offer_id":68079550497074,"sku":"2419082028","price":57.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7990d50f49a8013f7eddf9a964dc680a.gif?v=1793123500","url":"https:\/\/voomisupply.com\/products\/york-2420000000-heat-sequencer-relay-24-volt","provider":"Voomi Supply","version":"1.0","type":"link"}
