DESCRIPTION

The 35-63 is a 24 VAC intermittent pilot (spark-to-pilot) ignition 
control. The control uses a microprocessor circuit to provide 
precise, repeatable timing and operating sequences. On-board 
diagnostics with LED output makes troubleshooting easy and 
ensures safe and efficient operation.
