It is designed for low-voltage thermostat wiring in residential and light commercial HVAC systems. The cable provides the multiple signal conductors needed to connect a thermostat to a furnace, air handler, or heat pump control board. HVAC technicians and installers pull this cable during new construction and retrofit work where thermostat runs require a reliable, code-acceptable wiring solution.\u003c\/p\u003e\u003cp\u003eThis thermostat cable is suited for typical low-voltage control wiring applications in forced-air heating and cooling systems. The 250-foot spool length supports multiple thermostat runs from a single spool, reducing material waste on larger jobs. It is commonly used in residential single-family homes, light commercial tenant spaces, and multi-family buildings where standard 18-gauge low-voltage wiring is specified.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e18 AWG, 4-conductor configuration supports standard thermostat control wiring\u003c\/li\u003e\n\u003cli\u003e250-foot spool provides ample length for multiple runs or long single pulls\u003c\/li\u003e\n\u003cli\u003eUL listed for low-voltage thermostat wiring applications\u003c\/li\u003e\n\u003cli\u003eSuitable for residential and light commercial HVAC installations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard-supply thermostat cable for residential and light commercial low-voltage HVAC control wiring applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed HVAC technician in accordance with NEC low-voltage wiring guidelines. Power down the HVAC system at the disconnect or breaker before making any control wiring connections. Avoid running low-voltage thermostat cable in the same conduit as line-voltage wiring. Secure the cable at appropriate intervals per local code requirements.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Gauge\u003c\/strong\u003e: 18 AWG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Conductors\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpool Length\u003c\/strong\u003e: 250 feet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eListing\u003c\/strong\u003e: UL Listed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Low-voltage thermostat wiring\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HEATCONTROLLERMARS84203\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: MARS-84203\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HEAT CONTROLLER","offers":[{"title":"Default Title","offer_id":51525483823410,"sku":"MARS-84203","price":104.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c3a10cdfe6b6015ec1eed2dc81a48bc3.jpg?v=1785475210","url":"https:\/\/voomisupply.com\/products\/heatcontrollermars84203-mars-84203-thermostat-cable","provider":"Voomi Supply","version":"1.0","type":"link"}
