It had an adjustable temperature knob and was used in these Franklin automatic waterers: EEPC1, EEPC2, PC10, F52, E20 and H1.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eINSTRUCTIONS\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe brass thermostat monitored the temperature of the water and triggered the heaters as needed. To adjust it, the black knob was turned counter clockwise to turn the heat up and clockwise to turn the heat down. Several adjustments were usually needed to settle on a temperature. The range was 10 to 80 degrees Fahrenheit.\u003c\/p\u003e","brand":"Franklin","offers":[{"title":"Default Title","offer_id":44267707433155,"sku":"41604","price":69.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0682\/1894\/5731\/files\/1577661750.jpg?v=1740708771","url":"https:\/\/www.petecosupply.com\/products\/franklin-fru-thermostat-41604","provider":"PeteCo Supply, LLC.
