It regulates water temperature by opening the burner circuit when the set limit is reached while controlling the circulator to maintain efficient heat distribution. The device comes equipped with a built-in transformer for powering the 24V thermostat circuit and includes dedicated terminals for optional remote low-limit controllers or zone valve systems. Designed for horizontal mounting, the L8148A1017 provides dependable control with an adjustable range from 140°F to 240°F and a fixed 8°F differential, ensuring stable operation and consistent system performance.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eHigh Limit Temperature Control: Opens the burner circuit when water reaches the selected limit between 140°F and 240°F.\u003c\/li\u003e\n\u003cli\u003eFixed 8°F Differential: Ensures consistent temperature regulation for efficient boiler performance.\u003c\/li\u003e\n\u003cli\u003eIntegrated Transformer: Supplies 24VAC power for thermostat and control circuits.\u003c\/li\u003e\n\u003cli\u003eDual Function Switching: SPST design controls both the circulator and burner high-limit functions.\u003c\/li\u003e\n\u003cli\u003eRemote Control Compatibility: Includes terminals for connecting a low-limit controller or zone valve wiring.\u003c\/li\u003e\n\u003cli\u003eDurable Construction: Rugged metal housing ensures longevity and reliability in demanding HVAC applications.\u003c\/li\u003e\n\u003cli\u003eFlexible Installation: Designed for horizontal mounting with standard well depth and capillary configuration.\u003c\/li\u003e\n\u003cli\u003eThermostat Compatibility: Works with any 24VAC thermostat with a 0.2A anticipator setting.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe L8148A1017 delivers the reliability and precision required for hydronic heating systems, providing accurate temperature control, safety, and energy efficiency.\u003c\/p\u003e","brand":"Honeywell","offers":[{"title":"Default Title","offer_id":50671543845162,"sku":"L8148A1017","price":355.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/0392\/4266\/files\/s-l960_c680fe30-7a2d-447d-9f0c-c1544d4371b5.webp?v=1770321320","url":"https:\/\/iqelectro.com\/products\/honeywell-l8148a1017-aquastat-relay-available-now","provider":"IQElectro","version":"1.0","type":"link"}
