The thermostat that runs the heating will close the circulator relay which should turn on the system circulator and the boiler (which turns on the boiler circulator) - both at the same time. Don't mess with turning the system circulator on and off until somebody figures out that it should run to send water to the radiators whenver the thermostat calls for it to run.
