Check circulator terminals: If voltage is everywhere it should be and a relay is clicking constantly OR a transformer is buzzing, those component(s) are probably bad. Separately at RELAY CONTROL SWITCHES using a water pump pressure control switch as an example we discuss clicking and chattering relay switches.
