Description
The Carrier HM66SERIES308 Direct Spark Ignition Control that regulates the combustion sequence in gas-fired heating equipment within the HVAC systems. It generates a high-voltage spark to light the burner and monitors flame presence to confirm better operation. In HVAC systems, it coordinates ignition timing and gas valve response while initiating shutdown if a flame is not established. Usually located within furnace control assemblies, it supports proper burner startup and maintains consistent heating performance across residential and commercial units, contributing, to stable and accurate system operation.
