APPLICATION
The RM7895A,B,C,D/EC7895A,C; RM7896A,B,C,D are micro-
processor-based integrated burner controls for automatically
fired gas, oil, or combination fuel single burner applications.
They are intended to replace the R4795 and R7795 Primary
Controls. The RM7895A,B,C,D/EC7895A,C; RM7896A,B,C,D
systems consist of a relay module, subbase, amplifier, and
purge card. Options include: 2-line VFD (see document 65-
0090-6) or 4-line LCD (see document 32-00110-01) Key-
board Display Module, Personal Computer Interface, Data
ControlBus™ Module, remote display mounting, expanded
annunciator and Combustion System Manager® Software.
Functions provided by the RM7895A,B,C,D/EC7895A,C;
RM7896A,B,C,D include automatic burner sequencing, flame
supervision, system status indication, system or self-diagnos-
tics and troubleshooting. The RM7896 provides a postpurge
function.
