        Refrigeration controller for chilled and frozen applications<\/h4>\n

        The AT2-5 is a universal refrigeration controller for chilled and frozen storage.
        \nThe AT2-5 ICE features a modified front panel.
        \nThis was specifically designed for ICEBANK requirements.
        \nWith this electronic system, the ICEBANK function can be activated manually via the ICE button according to customer requirements.<\/p>\n","protected":false},"featured_media":11062,"comment_status":"closed","ping_status":"closed","template":"","meta":[],"product_brand":[],"product_cat":[66],"product_tag":[],"class_list":["post-11061","product","type-product","status-publish","has-post-thumbnail","product_cat-refrigeration-controller","first","instock","shipping-taxable","product-type-simple"],"_links":{"self":[{"href":"https:\/\/berndt-contec.de\/en\/wp-json\/wp\/v2\/product\/11061","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/berndt-contec.de\/en\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/berndt-contec.de\/en\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/berndt-contec.de\/en\/wp-json\/wp\/v2\/comments?post=11061"}],"version-history":[{"count":1,"href":"https:\/\/berndt-contec.de\/en\/wp-json\/wp\/v2\/product\/11061\/revisions"}],"predecessor-version":[{"id":11063,"href":"https:\/\/berndt-contec.de\/en\/wp-json\/wp\/v2\/product\/11061\/revisions\/11063"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/berndt-contec.de\/en\/wp-json\/wp\/v2\/media\/11062"}],"wp:attachment":[{"href":"https:\/\/berndt-contec.de\/en\/wp-json\/wp\/v2\/media?parent=11061"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/berndt-contec.de\/en\/wp-json\/wp\/v2\/product_brand?post=11061"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/berndt-contec.de\/en\/wp-json\/wp\/v2\/product_cat?post=11061"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/berndt-contec.de\/en\/wp-json\/wp\/v2\/product_tag?post=11061"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
