OPERATION

The R7184 is a microprocessor-based control. The
indicator light provides diagnostic information for lockout,
recycling and patented cad cell status. There is a manual
reset button to exit the lockout mode and enter the idle
mode. (See Fig. 2.) Operation is shown in Table 4.
TROUBLESHOOTING AND
MAINTENANCE
IMPORTANT
M19978A
Due to the potential hazard of line voltage, only
a trained, experienced service technician
should preform the troubleshooting procedures.
This control contains no field-serviceable parts.
Do not attempt to take it apart. Replace entire
control if operation is not as described.
To completely troubleshoot an oil burner installation,
check the burner and oil primary control for proper
operation and condition.
The indicator light on the oil primary control provides
lockout, recycle and cad cell indications as follows:
