update, i think it is definately the systemate is the cause of my issues, tonight the boiler after a few hours of start stop behavior, started up and continued going, so much so my wife complained about the heat, so I turned the thermostat down and ..... the boiler stayed running away, then it turn the timer on the systemate to off and ..... the boiler kept going, total ignoring the inputs, so i have had to turn the boiler its self to off. I will try turning off the mains power to the systemate to off when it cools down i do not want to leave it red hot in case something goes pop.
