Operating on a 24-volt control circuit, it uses timed switching to bring heating stages on and off in a controlled sequence, protecting components from simultaneous inrush loads. The on-delay range is 1 to 20 seconds and the off-delay range is 40 to 110 seconds. A built-in five-second delay between subsequent stages prevents simultaneous activation unless those stages are configured to operate together. Licensed HVAC technicians typically handle installation and commissioning of this component.\u003c\/p\u003e\n\u003cp\u003eThe tp-q103 is suited for residential and light commercial electric forced-air heating applications where staged element control is required. It fits into systems that use multiple heating elements or a combination of heating elements and blower motor circuits, providing orderly sequencing to reduce electrical demand spikes at startup. It is commonly installed in electric furnaces and air handler units that use resistance heat strips across a range of capacities.\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\u003eOn-delay range of 1 to 20 seconds and off-delay range of 40 to 110 seconds\u003c\/li\u003e\n  \u003cli\u003eFive-second inter-stage delay prevents simultaneous element energization\u003c\/li\u003e\n  \u003cli\u003eControls heating elements and blower motors in electric, gas, or oil heat systems\u003c\/li\u003e\n  \u003cli\u003eUL and CSA approved for use in North American installations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement sequencer for residential and light commercial electric, gas, or oil heat systems that require staged heating element and blower motor control on a 24-volt control circuit.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician. Disconnect all power to the air handler or electric furnace at the breaker before removing or installing the sequencer. Verify that the replacement unit matches the on and off timing specifications of the original before energizing the system. Follow applicable local electrical codes and NEC guidelines when making low-voltage and line-voltage connections.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eControl Circuit Voltage\u003c\/strong\u003e: 24 volts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOn-Delay Range\u003c\/strong\u003e: 1 to 20 seconds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOff-Delay Range\u003c\/strong\u003e: 40 to 110 seconds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInter-Stage Delay\u003c\/strong\u003e: 5 seconds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCertifications\u003c\/strong\u003e: UL, CSA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\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: TRADEPRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: tp-q103\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRADEPRO","offers":[{"title":"Default Title","offer_id":51383976493362,"sku":"TP-Q103","price":28.84,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312674785.webp?v=1782613826","url":"https:\/\/voomisupply.com\/products\/tradepro-tp-q103-sequencer-1-20-on-40-110-off","provider":"Voomi Supply","version":"1.0","type":"link"}
