The new (AFT) PC board kit has several new features. A 2-line 16 character LCD display with plain text diagnostics, improved flame sensing capabilities, an internal fuse and a service menu to aid in troubleshooting and maintenance. Once again Raypak leads the market with the first ever flame signal strength indicator that is graphical and easy to use. This new sensing and diagnostic capability will help reduce unnecessary parts change outs. Another industry first is the new board's ability to monitor the 24V power supply and provide useful diagnostic feedback without the use of a volt meter.
