Description
The Sterling HVAC 11J28R02721 Ignition Module is an electronic burner control unit used in gas heating systems to manage ignition sequencing and proper burner operation during heating cycles. It operates by receiving thermostat signals and coordinating spark generation or hot surface ignition while monitoring flame sensor output to confirm combustion before maintaining gas flow in HVAC systems. It controls ignition timing and responds to protection interlocks such as pressure switches and limit controls in forced-air systems. It operates as the central logic component for combustion control, providing proper ignition sequence execution, preventing improper fuel release, and maintaining consistent heating performance.
