It provides programmable temperature control without requiring separate thermostats for different hydronic applications. The TL8100A1008\/U manages heat-only systems by switching 2-way zone valves, 3-way zone valves, or circulator pumps. Licensed HVAC technicians and plumbers install this unit in residential and light commercial hydronic zones where scheduled setback control is needed to reduce energy consumption during unoccupied periods.\u003c\/p\u003e\n\u003cp\u003eThis thermostat is suited for a wide range of hydronic heating applications including baseboard convectors, radiant floor systems, and fan coil units controlled by zone valves or circulators. Its heat-only configuration makes it appropriate for boiler-based systems where no cooling control is required. The 7-day programming allows independent schedules for each day of the week, supporting varied occupancy patterns in both residential and small commercial settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e7-day programmable scheduling with independent daily programs for maximum scheduling flexibility\u003c\/li\u003e\n  \u003cli\u003eCompatible with 2-way zone valves, 3-way zone valves, and circulator pumps\u003c\/li\u003e\n  \u003cli\u003eHeat-only control eliminates unused cooling circuitry in dedicated hydronic systems\u003c\/li\u003e\n  \u003cli\u003eSingle thermostat handles multiple hydronic application types, reducing the need for multiple SKUs on the truck\u003c\/li\u003e\n  \u003cli\u003eProgrammable setback capability supports energy savings during unoccupied or overnight periods\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style programmable control for hydronic heating systems using 2-way zone valves, 3-way zone valves, or circulator pumps in heat-only residential and light commercial applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician or plumber familiar with low-voltage hydronic controls. Power down the boiler and de-energize all zone valve or circulator circuits before removing the existing thermostat or making any wiring connections. Follow all applicable local mechanical and electrical codes, including NEC requirements for low-voltage control wiring. Do not apply line voltage to low-voltage terminals.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProgramming Type\u003c\/strong\u003e: 7-Day Programmable\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem Type\u003c\/strong\u003e: Heat Only\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Outputs\u003c\/strong\u003e: 2-Way Zone Valves, 3-Way Zone Valves, Circulator Pumps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 085267298278\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: RESIDEO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: TL8100A1008\/U\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RESIDEO","offers":[{"title":"Default Title","offer_id":51383970398514,"sku":"TL8100A1008\/U","price":138.29,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312671168.png?v=1782613610","url":"https:\/\/voomisupply.com\/products\/resideo-tl8100a1008-u-7-day-programmable-hydronic-thermostat","provider":"Voomi Supply","version":"1.0","type":"link"}
