DESCRIPTION
The 35-61 is a 24 VAC direct spark ignition (DSI) control
designed for use in all types of gas-fired appliances. The control
uses a microprocessor to continually and safely monitor, analyze
and control the proper operation of a gas burner and inducer
blower. 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.
