For all intents and purposes these terms mean the same thing. The precise difference is that Floating refers to the controller (i.e, thermostat) and Tri-state refers to the controlled device (i.e, damper actuator or valve). A floating controller is used in conjunction with a tri-state actuator. The first floating controllers used the wiper attached to a bi-metal strip of a SPDT contact. The wiper moved (floated) between the two outer terminals so that at set point, the wiper did not connect with either of the outer terminals thus offering a tri-state operation (on\/off\/on). This is now most often done with electronic or digital controllers.<\/p>\n<p>Tri-state devices have three distinct modes described below.<\/p>\n<ul>\n<li>Motion in one direction (CW or stem up)<\/li>\n<li>No motion (@ set point)<\/li>\n<li>Motion in the opposite direction (CCW or stem down)<\/li>\n<\/ul>\n<p>So, if you have floating control then you must have a tri-state device to affect the change in the control loop. Kele has interface devices that can change an existing control scheme from proportional to tri-state (floating) signal by using a UCS-221 or a tri-state (floating) to a proportional signal by using a PWA-1T.<\/p>\n<p>[\/et_pb_text][\/et_pb_column][\/et_pb_row][\/et_pb_section]<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Q.What is the difference between Floating control and&#8230;<\/p>\n","protected":false},"author":1,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"full-width.php","meta":{"_et_pb_use_builder":"on","_et_pb_old_content":"","_et_gb_content_width":"","footnotes":""},"folder":[251],"class_list":["post-26765","page","type-page","status-publish","hentry"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.2 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\r\n<title>Floating Control vs Tri-State Control - kele.com<\/title>\r\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\r\n<link rel=\"canonical\" href=\"https:\/\/www.kele.com\/content\/technical-reference\/transducers\/floating-control-vs-tri-state-control\" \/>\r\n<meta property=\"og:locale\" content=\"en_US\" \/>\r\n<meta property=\"og:type\" content=\"article\" \/>\r\n<meta property=\"og:title\" content=\"Floating Control vs Tri-State Control - kele.com\" \/>\r\n<meta property=\"og:description\" content=\"Q.What is the difference between Floating control and...\" \/>\r\n<meta property=\"og:url\" content=\"https:\/\/www.kele.com\/content\/technical-reference\/transducers\/floating-control-vs-tri-state-control\" \/>\r\n<meta property=\"og:site_name\" content=\"kele.com\" \/>\r\n<meta property=\"article:modified_time\" content=\"2024-06-17T21:57:50+00:00\" \/>\r\n<meta name=\"twitter:card\" content=\"summary_large_image\" \/>\r\n<meta name=\"twitter:label1\" content=\"Est. reading time\" \/>\n\t<meta name=\"twitter:data1\" content=\"1 minute\" \/>\r\n<script type=\"application\/ld+json\" class=\"yoast-schema-graph\">{\"@context\":\"https:\/\/schema.org\",\"@graph\":[{\"@type\":\"WebPage\",\"@id\":\"https:\/\/www.kele.com\/content\/technical-reference\/transducers\/floating-control-vs-tri-state-control\",\"url\":\"https:\/\/www.kele.com\/content\/technical-reference\/transducers\/floating-control-vs-tri-state-control\",\"name\":\"Floating Control vs Tri-State Control - kele.com\",\"isPartOf\":{\"@id\":\"https:\/\/www.kele.com\/content\/#website\"},\"datePublished\":\"2023-08-25T22:24:48+00:00\",\"dateModified\":\"2024-06-17T21:57:50+00:00\",\"breadcrumb\":{\"@id\":\"https:\/\/www.kele.com\/content\/technical-reference\/transducers\/floating-control-vs-tri-state-control#breadcrumb\"},\"inLanguage\":\"en-US\",\"potentialAction\":[{\"@type\":\"ReadAction\",\"target\":[\"https:\/\/www.kele.com\/content\/technical-reference\/transducers\/floating-control-vs-tri-state-control\"]}]},{\"@type\":\"BreadcrumbList\",\"@id\":\"https:\/\/www.kele.com\/content\/technical-reference\/transducers\/floating-control-vs-tri-state-control#breadcrumb\",\"itemListElement\":[{\"@type\":\"ListItem\",\"position\":1,\"name\":\"Home\",\"item\":\"https:\/\/www.kele.com\/content\/\"},{\"@type\":\"ListItem\",\"position\":2,\"name\":\"Floating Control vs Tri-State Control\"}]},{\"@type\":\"WebSite\",\"@id\":\"https:\/\/www.kele.com\/content\/#website\",\"url\":\"https:\/\/www.kele.com\/content\/\",\"name\":\"kele.com\",\"description\":\"Kele is a single source supplier with a huge inventory for all your building automation requirements.
