My new boiler circulator pump cuts off 15 seconds or so after burner cuts off/thermostat temp is reached. This leaves this 170-200 degree hot iron boiler sitting there, making jerk Middle East oil sheiks very happy. The relay cover says there is a optional series 60 low limit control, is this what I need to let pump run until low limit limit is met? It is a Hydrotherm water oil fired boiler with Honeywell aquastat relay L8148A. Thanks for your help!
