Information About SV9541Q2561
The SV9541Q2561 is part of Honeywell’s SmartValve® System Controls, designed for advanced combustion management in modern gas-fired appliances. It combines a 24 Vac electronic intermittent pilot ignition module with a dual-stage gas valve and is compatible with the Q3450 or Q3480 pilot assemblies. The control provides prepurge, timed ignition trials, continuous retry operation, and LED diagnostics for easy troubleshooting. It can communicate directly with Honeywell’s ST9160 (single-stage) or ST9162 (two-stage) electronic fan timers and is certified for use with fan-assisted combustion appliances requiring precise ignition and flow control.
Key Features:
- Integrated Design: Combines electronic ignition control and dual-stage gas valve in one assembly.
- Two-Stage Operation: Provides low and high pressure regulator settings for efficient combustion.
- Intermittent Hot Surface Pilot Ignition: Ensures safe, reliable pilot and main flame ignition.
- Continuous Retry Sequence: Automatically retries ignition on flame failure for system reliability.
- Prepurge and Postpurge Cycles: Provides 15 s prepurge and 30 s postpurge to clear combustion gases.
- Diagnostic LED Display: Indicates system status and fault codes for quick troubleshooting.
- Flame Failure Response: 1.6 s shutoff reaction time at 3 µA for enhanced safety.
- Multi-Position Mounting: Operates reliably when installed 0°–90° from vertical orientation.
- CSA Certified: Approved for natural gas operation and meets safety standards for combustion control.
- Includes LP Conversion Kit: Enables conversion for propane applications when required.
The SV9541Q2561 delivers the reliability and precision required for dual-stage gas appliances requiring integrated safety and ignition control.
