The circulator relay on my Honeywell L8124C Aquastat is intermittently chattering while furnace is running. Do I need a new Aquastat or is some troubleshooting required?

    I'd try

    to disconnect the wires fro "T T" and jump it out. If it still chatters, than replace it, if not, go down the line to see what's tied into it. Zone valves, 1 thermostat, switching relays?
