System Mode
The MODE seng (Image 3.4.4) allows the user to choose between AUTOMATIC and MANUAL mode. In AUTOMATIC
mode the system automacally aempts to relight the pilot if ame is lost. In MANUAL mode the system will not
automacally aempt to relight the pilot.
BMS Module Timing Sengs
The following graphic (Image 3.4.3) depicts how each ignion ming sengs aects the enre ignion sequence.
Pilot On Demand
The ONDEMAND seng (Image 3.4.5) enables or disables the pilot on demand feature. When ONDEMAND is
disabled the system operates as a standing pilot system where the pilot is lit and kept lit while the system is acve.
When ONDEMAND is enabled the pilot is lit when one of the processes is acve. If no processes are acve, then the
pilot is shut-o unl a process becomes acve. Pilot on demand funconality works with all processes except for the
INDEPENDENT process.
