7800 SERIES Relay Modules

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.
