It mounts directly to the pipe surface, eliminating the need to cut into the line, and operates across a wide temperature range of 100 to 240 degrees F with a 10-degree F differential. Licensed HVAC technicians and plumbers install this control as part of zone valve or circulator pump circuits to maintain accurate zone temperature management in hot water heating systems.\u003c\/p\u003e\u003cp\u003eThis control is suited for residential and light commercial hydronic heating applications where zone-by-zone temperature control is required. The strap-on mounting design accommodates any fractional tube size, making it a versatile fit for copper, PEX, and other common hydronic piping without specialized adapters. It is typically installed on supply or return lines to monitor water temperature and trigger zone control actions based on system demand.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eStrap-on mounting fits any fractional tube size without pipe modification\u003c\/li\u003e\n\u003cli\u003eWide operating range of 100 to 240 degrees F suits most hydronic heating applications\u003c\/li\u003e\n\u003cli\u003e10-degree F (5.5-degree C) differential for stable, accurate temperature control\u003c\/li\u003e\n\u003cli\u003eSingle-unit package quantity suitable for individual zone installations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation control for residential and light commercial hydronic zone heating systems using standard fractional pipe sizes.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed HVAC technician or plumber familiar with hydronic heating systems. Shut down the boiler and relieve system pressure before mounting the control to the pipe. Secure the strap-on sensor firmly against the pipe surface for accurate temperature sensing, and ensure all low-voltage wiring connections comply with NEC requirements for the control circuit.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Type\u003c\/strong\u003e: Strap-on\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Tube Size\u003c\/strong\u003e: Any fractional tube size\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature Range\u003c\/strong\u003e: 100 to 240 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDifferential\u003c\/strong\u003e: 10 degrees F (5.5 degrees C)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.8 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 11 27 002S1\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WHITE-RODGERS","offers":[{"title":"Default Title","offer_id":51541936374066,"sku":"11 27 002S1","price":196.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6245b63c309eb307936a41bd83569769.jpg?v=1785888003","url":"https:\/\/voomisupply.com\/products\/white-rodgers-11-27-002s1-hydronic-zone-control","provider":"Voomi Supply","version":"1.0","type":"link"}
