Boiler water level monitoring and control system

In a system comprising a level sensor assembly, a computer having a memory and a boiler water level control system controller having historical boiler water level control system information, the controller in communication with the level sensor assembly and the computer, the computer programmed with a program to be stored in the memory for execution by the computer, and a float that is in operational association with the level sensor assembly, a method comprising:

• providing, upon execution of the program, computerized access to the historical boiler water level control system information from the boiler water level control system controller;
• and
• utilizing the historical boiler water level control system information in at least one of testing, over a specified amount of time, and
• diagnosing at least one boiler water level control system functionality;
• wherein the at least one boiler water level control system functionality includes a float check that includes monitoring the float to ensure that any movement of the float is sufficient for and within the specified period of time;
• and wherein monitoring the float to ensure any movement of the float is sufficient for and within the specified period of time includes deenergizing a low water cut off (LWCO) relay if a level bounce of the float in a period of at least a plurality of minutes is less than an inch.
