Climate controllers can be connected to the FarmWatch Pro system via a digital input. <\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Hardware Requirements<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The climate controller must have <strong>a solid-state output or a relay<\/strong> on its alarm output. Without such an output, it is not possible to connect the controller to the FarmWatch Pro&#8217;s digital input. <\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How many controllers can be connected?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">FarmWatch Pro has <strong>up to 8 digital inputs<\/strong>. If there are more than 8 climate controllers, you can group them\u2014for example, by sector (mating, gestation, farrowing)\u2014and connect each group to a single input. <\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How Does a Group Connection (Serial Loop) Work?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">When several controllers from the same sector are connected to a single digital input, this is done as <strong>a serial connection (loop)<\/strong> through all the controllers in the group. If an alarm occurs on any controller in the loop, the line is disconnected, the input status changes, and FarmWatch Pro triggers an alarm for that input. <\/p>\n\n\n\n&#8220;`svg\n<svg viewBox=\"0 0 900 360\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" role=\"img\" aria-labelledby=\"ctitle cdesc\" style=\"width:100%;height:auto;max-width:900px;display:block;margin0 auto;\">\n  <title id=\"ctitle\">Connecting climate controllers to FarmWatch Pro digital inputs<\/title>\n  <desc id=\"cdesc\">Comparison of two connection methods: a single climate controller connected to one digital input labeled with a specific location, and a group of three controllers from one sector connected in a loop to one input labeled with the sector name.<\/desc>\n  <style>\n    .c-box { fill:#ffffff;
