        Refrigeration Controller Positive Cooling \/ OEM<\/h4>\n

        The AT1-5 series comprises cost-effective refrigeration controllers with heating or cooling functions and a high-power relay up to max. 16A (heating) and 8A (inductive compressor switching capacity).
        \nIts strengths lie in its simple configuration, self-explanatory membrane keypad, an INFO menu with essential information, and a door contact switch.
        \nThe second output’s function can be freely selected and triggered, for example, via the I\/O button or, for lighting control, via the M button.<\/p>\n","protected":false},"featured_media":11091,"comment_status":"closed","ping_status":"closed","template":"","meta":[],"product_brand":[],"product_cat":[66],"product_tag":[],"class_list":["post-11090","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\/11090","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=11090"}],"version-history":[{"count":1,"href":"https:\/\/berndt-contec.de\/en\/wp-json\/wp\/v2\/product\/11090\/revisions"}],"predecessor-version":[{"id":11092,"href":"https:\/\/berndt-contec.de\/en\/wp-json\/wp\/v2\/product\/11090\/revisions\/11092"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/berndt-contec.de\/en\/wp-json\/wp\/v2\/media\/11091"}],"wp:attachment":[{"href":"https:\/\/berndt-contec.de\/en\/wp-json\/wp\/v2\/media?parent=11090"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/berndt-contec.de\/en\/wp-json\/wp\/v2\/product_brand?post=11090"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/berndt-contec.de\/en\/wp-json\/wp\/v2\/product_cat?post=11090"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/berndt-contec.de\/en\/wp-json\/wp\/v2\/product_tag?post=11090"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
