This is one of the ones that the AutoHot determines when you ‘demand’ hot water. This is one type of activator for the on-demand recirculation system. Other options include wireless motion sensors and wireless push buttons.
Please note, the hardwired pushbutton will slide snugly into a 5/8″ hole. Oftentimes this will be drilled into the front of your cabinet, right by the sink.
For multiple buttons, view the following video, fast forward to the middle at about 2:36 to see the section on connecting multiple buttons. Please note, the crimp wire connectors are not included in the piece.[tvideo type=”youtube” clip_id=”8byJTuwBmHw” autoplay=”false” loop=”true”]
