QUESTION FROM Dave

I have a Bryant, three zone, Gas Boiler Furnace.
It turned on when the weather was warm and the thermastats where turned off. The only why I can stop it is to turn off the electrical beaker switch. What is causing the furnace to not read the thermastat? Is this something that I can troubleshoot and replace myself?

If your thermostat for your furnace is not working properly, yes, there are a number of things that you can check to diagnose the cause. Here is a webpage that describes some general troubleshooting techniques for a problem thermostat:
