Operating at 21 volts DC, this sensor feeds real-time enthalpy data to the economizer controller, allowing the system to determine when outdoor air conditions are suitable for free cooling. It is a field-mounted sensor intended for installation by licensed HVAC technicians as part of a commercial or light-commercial economizer control strategy. The unit measures 5 inches in length, 1.5 inches in width, and 3.75 inches in height, weighing approximately 1 pound.\u003c\/p\u003e\n\u003cp\u003eThe c7400s1000 is used in HVAC applications where outdoor air enthalpy sensing is required to enable or disable economizer operation. It is paired with the W7220 economizer controller and communicates over the S-Bus protocol. Typical installations include rooftop units and air handling units in commercial buildings where energy codes require demand-controlled or enthalpy-based economizer lockout. This sensor supports compliance with ASHRAE 90.1 and similar energy efficiency standards that mandate enthalpy-based economizer control.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMeasures both humidity and temperature to calculate outdoor air enthalpy\u003c\/li\u003e\n  \u003cli\u003eCompatible with S-Bus communication protocol for direct integration with supported controllers\u003c\/li\u003e\n  \u003cli\u003eDesigned for use with the W7220 economizer controller\u003c\/li\u003e\n  \u003cli\u003eOperates at 21 volts DC\u003c\/li\u003e\n  \u003cli\u003eCompact form factor: 5 inches x 1.5 inches x 3.75 inches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with S-Bus devices and the W7220 economizer controller, as specified by the manufacturer.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician familiar with economizer control systems and low-voltage sensor wiring. Disconnect and lock out power to the economizer controller and associated equipment before beginning any wiring work. Follow the W7220 controller wiring diagrams and applicable local codes when connecting the S-Bus communication leads. Mount the sensor in a location that accurately represents outdoor air conditions, away from exhaust outlets, direct sunlight, and other sources of heat or moisture that could skew readings.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage\u003c\/strong\u003e: 21 volts DC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 3.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: Mexico\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: HONEYWELL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: c7400s1000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HONEYWELL","offers":[{"title":"Default Title","offer_id":51672303567154,"sku":"C7400S1000","price":84.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/97d4154ef3992774c2ef856377393624.webp?v=1787965775","url":"https:\/\/voomisupply.com\/products\/honeywell-c7400s1000-digital-enthalpy-sensor","provider":"Voomi Supply","version":"1.0","type":"link"}
