Description
The Fenwal 35‑705700‑001 Ignition Control Module and its equivalent listings are industrial-grade 120 VAC Direct Spark Ignition (DSI) control modules used to manage safe and reliable spark ignition in gas-fired heating systems, furnaces, boilers, water heaters, and other combustion equipment.
Key Features
- Direct Spark Ignition (DSI): Provides electronic spark ignition without a standing pilot, improving energy efficiency and startup reliability.
- 120 VAC Power: Compatible with standard line-voltage gas heating systems for robust operation.
- Microprocessor Control Logic: Ensures repeatable and precise ignition timing with controlled sequences for dependable burner starts.
- 4-Second Trial for Ignition (TFI): The module allows about 4 seconds for flame establishment during each ignition attempt.
- Single Ignition Trial: Designed with one ignition attempt before lockout to safely detect ignition failures.
- No Pre-Purge/Inter-Purge: Configured without pre-purge or inter-purge timing for straightforward ignition sequencing.
- Flame Sensing: Built-in flame sense circuit detects combustion presence to prevent unsafe operation if flame is not established.
- Solid Construction: Designed to withstand typical HVAC environments with conformal coatings and rugged components.
