The HI cut off temperature for the burner: on a typical aquastat or combination control, the "Hi Limit" setting specifies the cut-off temperature for the heating boiler's burner on a call for heat. That means that when the burner is running it will heat water inside the heating boiler until that water temperature reaches the HI or cut-off point.. Versatile and compact, they are easily installed to operate with either a probe- or float-type low water cut-off. The feeders are always ready to add water when given the signal from the LWCO - no need to manually add water..
