Russ here. Welcome. I am here to help. Please do not rate until you are satisfied with answer. Always available for follow up questions. Sal if you are using the 950 you must using an interface board for system. 126 is loss of communication between thermostat and board. If you have float switch in the drain it could possibly be tripped and you will have loss of communication. Russ
