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.

Abstract: A switch assembly features an automatic switch and an electronic circuit board. The automatic switch has a common contact and a normally open switch contact to short when a boiler has sufficient water, and has the common contact and a normally closed switch contact to short when the boiler has a low water level. The electronic circuit board has a signal processor, a reset switch, and a low water status LED for providing a status indication of a low water condition that remains ON even if the water level has risen unless the reset switch is reset. The signal processor couples to the common contact, the normally closed switch contact and the normally open switch contact, senses signaling containing the status of the common contact, the normally closed switch contact and the normally open switch contact, provides corresponding signaling to turn ON the low water status LED when the water level is low, and responds to a reset switch signal and turn OFF the low water status LED.

Abstract: A low water cutoff switch controller features a dual inline package (DIP) in combination with low water cutoff switch processor. The dual inline package (DIP) has DIP switches, each DIP switch configured to set in a respective application type or mode corresponding to a particular water heater model for the low water cutoff switch controller to control, and also configured to provide DIP switch signaling containing information about a respective DIP switch set. The low water cutoff switch processor is configured to respond to the DIP switch signaling, and also configured to respond to corresponding signaling containing information about a sensed water level contained in the particular water heater model being controlled by the low water cutoff switch controller, and provide control signaling containing information to control the operation of the particular water heater model. The low water cutoff switch controller is a single controller that can be used for controlling any one of a plurality of different water heater models and have different voltage applications by setting a respective one of the DIP switches.

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.
