It can be interlocked with virtually any burner control circuit.  Features include: adjustable pre \u0026amp; post purge, LED status \/ diagnostic indicators, 10 second prover switch delay to avoid burner start up and wind induced short cycling.  Interlocks with any 24-120 VAC burner control circuit and also includes dry contact actuation option. Selectable voltage eliminates false activation by burner control circuits.  After each burner cycle the UC1 will continue to operate in post-purge mode to allow the venter to purge the heater and vent of residual flue gases.  A factory post-purge time is set at 2 minutes and is adjustable up to 16 minutes\u003c\/span\u003e\u003cspan style=\"font-size: 12pt;\"\u003e.\u003c\/span\u003e\u003c\/span\u003e\u003cspan style=\"font-size: 12pt; font-weight: bold; text-decoration: underline;\"\u003e\u003cbr\u003e \u003c\/span\u003e\u003c\/span\u003e\u003cbr\u003e \u003cbr\u003e \u003cspan style=\"font-size: 12pt;\"\u003e\u003cspan style=\"color: #000000; font-size: 12pt; font-weight: bold; text-decoration: underline;\"\u003e\u003cspan style=\"font-size: 12pt;\"\u003eThe UC1 Universal control is standard in the following models:\u003c\/span\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/span\u003e \u003cspan style=\"font-size: 12pt;\"\u003e\u003cbr style=\"color: #000000;\"\u003e \u003cspan style=\"font-size: 12pt;\"\u003e\u003c\/span\u003e\u003c\/span\u003e \u003cspan style=\"font-size: 12pt;\"\u003e\u003cspan style=\"font-size: 12pt;\"\u003e\u003cspan style=\"font-size: 12pt; color: #000000;\"\u003eHSJ, HS1, HS2, HS3, HS4, HS5\u003c\/span\u003e\u003c\/span\u003e\u003cspan style=\"font-size: 12pt;\"\u003e\u003cspan style=\"font-size: 12pt; color: #000000;\"\u003e, SS1, SS1C, SS1R, SS2\u003c\/span\u003e\u003c\/span\u003e\u003cbr\u003e \u003cbr\u003e \u003cbr style=\"font-weight: bold;\"\u003e \u003cspan style=\"font-weight: bold;\"\u003eRESOURCES\u003c\/span\u003e\u003c\/span\u003e \u003cspan style=\"font-size: 12pt;\"\u003e\u003cbr\u003e \u003c\/span\u003e\u003cul style=\"\"\u003e\n\u003cli\u003e\u003cspan style=\"font-size: 12pt;\"\u003e\u003ca href=\"http:\/\/www.tjernlund.com\/Tjernlund_8500004.pdf\"\u003eTjernlund UC1 Universal Control Brochure\u003c\/a\u003e\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"font-size: 12pt;\"\u003e\u003ca href=\"http:\/\/www.tjernlund.com\/Tjernlund_8505017Addendum_b.pdf\"\u003eTjernlund UC1 Universal Control Instructions\u003c\/a\u003e\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\u003cspan style=\"font-size: 12pt;\"\u003e\u003cbr\u003e \u003c\/span\u003e\u003cdiv style=\"margin-left: 40px; \"\u003e\u003cspan style=\"font-size: 12pt;\"\u003e\u003cbr\u003e \u003cbr\u003e \u003c\/span\u003e\u003c\/div\u003e","brand":"Tjernlund","offers":[{"title":"Default Title","offer_id":47344106668205,"sku":"18124","price":137.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0785\/5895\/3645\/files\/Tjernlund_20-_20UC1.png?v=1787902764","url":"https:\/\/www.bostonheatingsupply.com\/products\/tjernlund-uc1-universal-control","provider":"Boston Heating Supply","version":"1.0","type":"link"}
