RM7800L1053 Honeywell Burner Control

RM7800L1053 Datasheet The Honeywell RM7800L1053 Burner Control 120V, 50/60 HZ. WITH INTERMITTENT Pilot. Honeywell RM7800L1053 Integrated Burner Control – 120 VAC Flame Safeguard for Single Burner Systems Overview The Honeywell RM7800L1053 is a microprocessor-based integrated burner control designed for single burner systems using gas, oil, coal, or combination fuels. Engineered for automatic flame supervision, diagnostics, and safety, it delivers reliable performance for commercial and industrial installations. With user-selectable airflow check, post-purge, pilot flame options and built-in display (S7800), this burner control ensures compliance, ease of maintenance, and safe shutdown in fault conditions. Key Features & Benefits Multi-Fuel Flexibility – Supports gas, oil, coal, or combination fuels; ideal for diverse burner operations. Pilot Control Options – Offers interrupted pilot, intermittent second-stage pilot valve; pilot flame establishing periods of 4 or 10 seconds. Main Flame Establishing – Standard 10 seconds (or intermittent mode), with early spark termination (5 seconds). Airflow Check & Post-Purge – User selectable airflow check ensures safe ambient conditions; includes a 15-second post-purge to clear residual fuel/combustion gases. Display & Diagnostics – Incorporates S7800 Keyboard/Display Module; non-volatile memory retains history and lockout status after power loss. LEDs run/test switch provide status & troubleshooting cues. Rugged Performance – Operates in wide ambient temperature range (-40°F to 140°F / -40°C to 60°C); certified by UL, CSA; FCC emissions compliance.

OEM Honeywell Product – authentic parts, full technical specs, quality assured In-Stock & Ready to Ship – real-time stock availability reduces project delays Proven Reliability – non-volatile history, diagnostics, display module help minimize downtime and simplify troubleshooting FAQs Q: What happens if there is a loss of airflow?A: With the airflow check enabled, the unit will prevent ignition if airflow is insufficient; this feature protects against unsafe combustion. Q: Can this control work with older flame detectors or amplifiers?A: Yes — it is compatible with existing Honeywell flame detectors and interchangeable flame signal amplifiers like R7847, R7848, R7849, R7851, R7852, R7861, or R7886. Q: What type of fuel flexibility is supported?A: Supports gas, oil, coal, or any combination of these; pilot and secondary pilot options allow flexibility in flame supervision. Q: What display and diagnostics does this control provide?A: Includes the S7800 display module, LED indicators, run/test switch, and non-volatile memory to retain lockout history even after power loss.
