APPLICATION
The Honeywell EC/RM7830A and EC/RM7850A are
microprocessor-based integrated burner controls for
automatically fired gas, oil, or combination fuel single burner
full modulation (EC/RM7850A) or on/off (EC/RM7830A)
applications. The EC/RM7830A; EC/RM7850A system
consists of a relay module, subbase, amplifier, and purge
card. Options include keyboard display module (KDM),
Personal Computer Interface, Data ControlBus Module™,
remote display mounting and Combustion System Manager®
Software.
Functions provided by the EC/RM7830A and EC/RM7850A
include automatic burner sequencing, flame supervision,
system status indication, system or self-diagnostics and
troubleshooting. Text readout on the Keyboard Display Module
is available in English, Spanish, Portuguese, Katakana
(Japanese), French, Chinese, German, and Italian languages.

appliances with or without fans.”
Please note the following to comply with EN60730 for remote
mounting of the KDM and/or remote reset module. It is
necessary to provide electrical separation using insulation at
least equivalent to double or reinforced insulation. This can be
accomplished by either:
1. Optically isolating the communication and/or remote
reset lines from the control cabinet or
2. Providing physical separation from the communication
and/or remote reset lines using electrical conduit and a
204718a Remote Display Cover Assembly or other
suitable enclosure that meets ip40 class of protection.
