System Architecture and Components
The Honeywell RM7895A1014 primary control requires several components for full operation. It must work with a Q7800 series wiring subbase, a compatible flame amplifier (R7847, R7848, R7849, R7851, R7852, R7861, or R7886), and a ST7800A plug-in purge timer card . Options include a keyboard display module for local configuration and a Combustion System Manager software for advanced system management .
Integration and Application
The Honeywell RM7895A1014 primary control handles sequencing, flame monitoring, and safety lockout functions . It retains history files in non-volatile memory even after a power loss . The module includes five LEDs that indicate sequence status and fault conditions. You can deploy this primary control in commercial and industrial burner systems requiring reliable flame supervision and safety interlocking.
