Abstract: A LWCO remote monitoring and diagnosing system or device features a signal processor configured to: receive signaling containing information for running a remote low water cut off (LWCO) mobile application, and also containing information about historical data related to a LWCO circuit that monitors and controls a burner of a boiler that opens and closes to provide water to the boiler depending on the water level in the boiler; and determine corresponding signaling containing information about the historical data requested based upon the signaling received.

Abstract: A switch assembly includes an automatic type 11 switch having 1 and 2 contacts and 3 and 4 contacts with the 2 and 3 contacts being shorted together, configured to respond to a water level of a boiler, short the 1 and 2 contacts when the water level is high, short the 3 and 4 contacts when the water level is low; and an electronic circuit board having a processor configured to sense signaling containing information about the 1, 2/3 and 4 contacts, and provide control signaling containing information about the water level of the boiler. The electronic circuit board also includes a relay configured to respond to the control signaling, and turn the relay on/off.
