It is listed for the H-Series and H-Series ED1 models 150 through 400, and for the ED2 style H-Series electronic gas heaters.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat the limiter does\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe temperature limiter is a safety cutout. It watches water temperature at the heat exchanger and shuts the heater down before things get hot enough to do damage. Because it is a safety device, a heater that will not fire because of the limiter should be diagnosed, not bypassed.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eBefore you replace it\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA limiter that trips over and over is often doing its job correctly. Low flow through the heater, a dirty filter, a closed valve or a heat exchanger fouled with scale all raise exchanger temperature and set the limiter off. Confirm flow and exchanger condition first, then change the limiter if it is the part that has failed.\u003c\/p\u003e","brand":"Hayward","offers":[{"title":"Default Title","offer_id":48628841578708,"sku":"HAY-151-1215","price":121.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_12e7a68e-7497-42ea-80ce-8bce32054eab.jpg?v=1788755136","url":"https:\/\/www.activepoolsupply.com\/products\/temperature-limiter-kit","provider":"Active Pool Supply","version":"1.0","type":"link"}
