Post Weil-Mclain CG Boiler

Hi, I am having a problem with this boiler and perhaps somebody can help me to solve this situation. I turned my unit on from my home thermostat and when it was time to turn it off, it did not turn off. The boiler continued running at a very high temperature. I disconnected the thermostat and even put the wires together trying to turn it off, but nothing worked. I bought another thermostat, but did not work either. What should I do?. Thanks. The model OG-5-SPDN. Serie #12
