Welcome to Just Answer, my name is ***** ***** I will do my best to help you with your issue. If my initial response doesn’t answer your question then let me know and we can continue our conversation.

STA 15 indicates an open limit. Is the boiler hot? if not you may have a bad temp sensor assuming you have a call for heat.
