Operating on 24-volt and millivolt systems, it uses a built-in bimetal element to sense and regulate temperature without electronic components. The thermostat features enclosed contacts that improve reliability and temperature accuracy over time. A licensed HVAC technician typically handles installation, though experienced DIYers working within local code requirements may also install this unit. The 1F56N-444 is a straightforward, no-frills control suitable for single-stage heating and cooling systems.\u003c\/p\u003e\n\u003cp\u003eThis thermostat is rated for use on single-stage furnaces, central air conditioners, and heat pumps. It supports both heating and cooling modes with an auto fan setting. The included 3-wire zone mounting plate simplifies installation on standard wall locations. Its mechanical design suits applications where a simple, dependable temperature control is preferred over programmable or digital alternatives. Typical installations are found in residential homes, apartments, and small commercial spaces served by conventional split systems or heat pump configurations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMercury-free construction meets current environmental and disposal standards\u003c\/li\u003e\n  \u003cli\u003eCompatible with 24-volt and millivolt low-voltage systems\u003c\/li\u003e\n  \u003cli\u003eBuilt-in bimetal thermometer for passive, reliable temperature sensing\u003c\/li\u003e\n  \u003cli\u003eEnclosed contacts for improved reliability and temperature accuracy\u003c\/li\u003e\n  \u003cli\u003eIncludes 3-wire zone mounting plate for straightforward installation\u003c\/li\u003e\n  \u003cli\u003eSupports heating, cooling, and auto fan modes on single-stage systems\u003c\/li\u003e\n  \u003cli\u003e3-year manufacturer warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on single-stage furnaces, air conditioners, and heat pumps operating on 24-volt or millivolt low-voltage systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified HVAC technician in accordance with local codes and the equipment manufacturer guidelines. Always shut off power to the HVAC system at the breaker before removing the existing thermostat or making any wiring connections. Mount the thermostat on an interior wall away from drafts, direct sunlight, and heat sources to ensure accurate temperature sensing. Verify system voltage compatibility before wiring to avoid damaging the thermostat or connected equipment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem Compatibility\u003c\/strong\u003e: Single-stage furnaces, air conditioners, heat pumps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage\u003c\/strong\u003e: 24 volts and millivolt systems\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDimensions\u003c\/strong\u003e: 3.50 inches x 5.24 inches x 2.52 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.28 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWarranty\u003c\/strong\u003e: 3 years\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: WHITE-RODGERS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1F56N-444\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WHITE-RODGERS","offers":[{"title":"Default Title","offer_id":67616569196850,"sku":"1F56N-444","price":56.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/208407637.jpg?v=1790437508","url":"https:\/\/voomisupply.com\/products\/white-rodgers-1f56n-444-mechanical-thermostat-low-voltage","provider":"Voomi Supply","version":"1.0","type":"link"}
