The Honeywell RM7800L1079 is a microprocessor-based burner control designed for managing automatically fired gas, oil, or combination fuel single burner applications. It provides automatic burner sequencing, flame supervision, system status indication, system or self-diagnostics, and troubleshooting. The control system comprises a relay module, a keyboard display module, a wiring subbase, a flame amplifier, and an optional purge card. The RM7800L1079 is suitable for on-off, modulating, and high-low-off control of burners.
Key Features:
-
Automatic Sequencing: Manages burner startup, operation, and shutdown sequences to ensure safe and efficient performance.
-
Flame Supervision: Monitors the presence of flame using compatible flame detectors, initiating safety shutdowns if flame loss is detected.
-
System Diagnostics: Performs continuous self-checks and provides diagnostic information to aid in troubleshooting and maintenance.
-
Modular Components: Features a modular design with plug-in components, facilitating easy installation, maintenance, and upgrades.
-
Communication Capabilities: Supports remote monitoring and data acquisition through optional communication modules, enabling integration with building management systems.
