Welcome to Just Answer, my name is ***** ***** I will do my best to help you with your issue. If my initial response doesn’t answer your question then let me know and we can

continue our conversation.

Your room thermostat is the primary control for the system/zone pump. This pump will run as long as there is a call for heat from the thermostat. So it's more likely you have a bad room thermostat or possibly a live short in the wiring from the stat to the boiler or zone valve. But I need more info on your system. What's the actual model number of your boiler? how many zones do you have? if more than 1 do you have zone valves or a pump for each zone?
