Information About R7795A1001
The R7795A1001 burner control is part of Honeywell’s robust flame safeguard product line and is designed for use in oil-burning systems that require interrupted ignition or intermittent pilot sequences. Operating at 120 VAC and supporting 50/60 Hz frequency, this control includes alarm contacts and a plug-in prepurge timer (configurable from 1.5 to 90 seconds). It uses a color-coded UV amplifier (purple) to detect flame presence and supports automatic lockout if flame is sensed at an incorrect time—preventing unsafe startups. The unit is mounted on a Q795A subbase and features a line-voltage airflow switch to verify airflow during the prepurge and run cycles.
Key Features:
- Ultraviolet Flame Detection: Supports UV flame sensing through a purple-coded amplifier for reliable flame signal recognition.
- Prepurge Timer Compatibility: Accepts plug-in timers with durations from 1.5 to 90 seconds for prepurge sequencing.
- Intermittent Pilot and Interrupted Ignition: Provides flexible burner startup sequences to fit various system designs.
- Alarm and Lockout Functions: Offers flame failure lockout and alarm output to alert operators to unsafe conditions.
- Wide Temperature Range: Operates reliably from -40°F to 135°F in challenging industrial environments.
- Mounting Simplicity: Installs on a Q795A subbase using two captive screws for fast service and replacement.
- Airflow Verification: Includes line-voltage airflow switch support to ensure proper combustion air during operation.
The R7795A1001 safeguards combustion processes by coordinating safe ignition, flame sensing, and emergency shutdown operations.
