        Thermostat for wall mounting<\/h4>\n

        The AC1-2W is a thermostat for wall mounting with a jet-proof housing.
        \nIn the menu, you can select the operating mode (heating\/cooling) for each channel, as well as whether you wish to control the channel with hysteresis or with PID control!
        \nFor easy configuration, it is equipped with a guided parameter programming system, so that only the parameters required for the specifically selected application are displayed.
        \nThis makes programming the controller faster and more efficient. The two setpoints can be adjusted to requirements in an instant using the L1 and L2 buttons. Naturally, the AC1-2W also features a standby (I\/O) button and an info menu. <\/p>\n","protected":false},"featured_media":11038,"comment_status":"closed","ping_status":"closed","template":"","meta":[],"product_brand":[],"product_cat":[70],"product_tag":[68],"class_list":["post-11070","product","type-product","status-publish","has-post-thumbnail","product_cat-thermostats","product_tag-discontinued-model","first","instock","shipping-taxable","product-type-simple"],"_links":{"self":[{"href":"https:\/\/berndt-contec.de\/en\/wp-json\/wp\/v2\/product\/11070","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=11070"}],"version-history":[{"count":1,"href":"https:\/\/berndt-contec.de\/en\/wp-json\/wp\/v2\/product\/11070\/revisions"}],"predecessor-version":[{"id":11071,"href":"https:\/\/berndt-contec.de\/en\/wp-json\/wp\/v2\/product\/11070\/revisions\/11071"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/berndt-contec.de\/en\/wp-json\/wp\/v2\/media\/11038"}],"wp:attachment":[{"href":"https:\/\/berndt-contec.de\/en\/wp-json\/wp\/v2\/media?parent=11070"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/berndt-contec.de\/en\/wp-json\/wp\/v2\/product_brand?post=11070"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/berndt-contec.de\/en\/wp-json\/wp\/v2\/product_cat?post=11070"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/berndt-contec.de\/en\/wp-json\/wp\/v2\/product_tag?post=11070"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
