My boiler is set to the aquastat all the way down to 140 and the burner will fire until 200 is reached then shut off after the relief valve shoots out steam and water. I am not sure if it does this because there is a limit, but seems like the connection from my thermostat to the boiler isn't working. Thermostat is wired properly, but when I set the thermostat to 15C, it goes up to 20C at times, can anyone help? I have a technician coming in during the week but is cold and would like to see if i can fix this. I have heat just have to manual shut down the power to the boiler because it reaches 200 which throws the relief valve open. With the high and low points on the relay set to the lowest, why is it going to 200? wiring problem? I can manually turn on the power and run the burner until 160 and shut it down but the curc pump will not run as well. The boil was to heat a small apartment building maybe 8 units, would i have to replace the nozzle to a lower btu nozzle?
