NEW FEATURES IN THE BECKETT R7184 SERIES 5
PRIMARY CONTROLS
Advances in electronics technology are making an exciting impact in our oilheat industry.These developments
have enabled control manufacturers to put high-performance features into residential primary controls.
Since its introduction in 1999, the Beckett R7184 primary control has made advancements and added
features to meet the need of a changing industry. This technical bulletin will discuss some of the new
benefits and wiring improvements to the Beckett R7184 revision 5 primary control.
The operational sequence, interrupted
ignition, limited recycle and reset,
diagnostic LED and communication
port remain consistent on the R7184A,
B, P revision 5 as with the previous
revision.
BENEFITS
•Matching wire colors between components and control will
reduce mistakes during wiring.
•Quick Connects on the lead wires from the burner components
and wire harnesses allow quick component change-out and
reduce the number of leads in the wiring box.
•Data port connection enables reading control characteristics
with Honeywell Diagnostick™
, QS7100T tester or OnWatch
QuickRead™711.
•EnviraCOM™communication terminals have been added for
future networking customization for HVAC systems.

WIRING SYSTEM CHANGES
Beckett burners have taken advantage of the changes in the R7184 controls to improve the wiring
system. Component and power cord wires, now color-coded to match the terminal colors on the
control, are terminated with 0.25-inch flag terminals (QCs) to fit the spade connectors (QCs) on the
control. During the time required to convert all components and controls to the new wiring system,
some adaptations may be required when replacing individual components on the burner.
CHANGING COMPONENTS —When changing components, the type of connection that you need
to make depends on the way the components (motor, valve, igniter), power cord and control are
terminated. Where all the leads / connections are the same, no modifications are required. Where
the two ends of a connection are dissimilar, see the options in the following table:
Reduced number of leads in wiring box.
Fig. 1– Cutting lead from component to be
replaced to use as jumper
Fig. 2– Using jumper to connect to new
component with stripped leads
