My oil boiler has been giving me headaches lately. I have 3 zones plus hot water. All 4 are working properly in terms of the thermostat and zone valves. Once the boiler reaches 190 degrees, it shuts off. It allows itself to drop in temperature and will not restart to get to the 190 degrees again. I have to manually reset it by hitting the reset button. And then the process repeats. If I lower the thermostats to where the house is not calling for heat, then the boiler just allows itself to drop and become cold. then, I need to hit the reset button again. who's got some ideas what to do next? again, thermostats and zone valves are functioning just fine.
