The RM7823A provides flame switch functions while
providing ongoing internal logic tests. Safety shutdown will
occur if the RM7823A fails any internal system test.
The RM7832A is a Flame Switch that has components
monitored by a computer. It is necessary for a RESET button
to put the computer in sync with real-time but is not intended
for safety lockout on loss of flame.
