Honeywell S4962BF1004U Boiler Control

Description

 

This printed circuit board is a genuine Honeywell spare part. Present in all domestic and commercial boilers, the printed circuit board (PCB)
handles all functionality and is pre-programmed with routines to operate the particular boiler it was designed for. Every action that occurs within a boiler is initiated, controlled, and carefully monitored by this PCB. Sensors connected by wires transmit the data that makes it possible for the PCB to access live readings and react accordingly. Vitally, the PCB can restrict operation instantly if a safety concern is detected. Some large or complex systems can require two or more PCBs for normal operation
