Last night my circulator was running when there was no call for heat from the house. I checked the manual but there isn't anything about this and it should only run if it overheats. The boiler was in idle mode and 181 degrees. I didn't have an error code either. I'm wondering if it's stuck on because it had been running once every 2 min for around 30 seconds. I tried pushing the stop and start button and even turning it off completely but nothing changes. Has anyone had this problem before?
 
Went out about 1/2 hour ago and it's back to normal. I don't know.
 
Could it be the wire to the thermostat is got a loose connection
