Description
The Fenwal 35-705700-005 Ignition Control Module is a 120 VAC microprocessor-based Direct Spark Ignition (DSI) control built for reliable and safe burner ignition in gas-fired HVAC systems, industrial heaters, boilers, water heaters, and other combustion applications. This module delivers precise timing, dependable flame sensing, and easy diagnostics to help ensure efficient ignition performance and reduced service issues.
Key Features
- Direct Spark Ignition (DSI): Uses electronic spark ignition to light burners without a standing pilot, improving efficiency and ignition reliability.
- 120 VAC Input: Designed for standard line-voltage operation in commercial and industrial gas appliances.
- Microprocessor-Based Logic: Provides accurate and repeatable ignition timing sequences and control logic for safe starts.
- 10-Second Trial for Ignition (TFI): Allows a defined window (about 10 seconds) for flame establishment before lockout.
- Single Ignition Attempt: Configured for one ignition trial before lockout, helping to prevent unsafe gas accumulation.
- Flame Sensing & Diagnostics: Verifies flame presence and includes on-board LED diagnostics (where equipped) to support rapid troubleshooting and maintenance.
- Durable Construction: Built to withstand typical HVAC and industrial environments with rugged design and moisture resistance.
