DESCRIPTION
The 35-60 is a 24 VAC direct spark ignition (DSI) control
designed for use in all types of gas-fired appliances. The control
uses a microprocessor circuit to provide precise, repeatable
timing and operating sequences. A diagnostic LED and optional
UART communications make troubleshooting easy and ensures
safe and efficient operation.
The optional UART communications offers advanced diagnostic
data and connectivity with the Fenwal ConnectedControl series
05-50 Wi-Fi device.
