Precise Manifold Regulation: maintains consistent BTUs when switching to higher-density propane fuel

Optimized Adsorption: Specifically formulated for high moisture capacity and acid neutralization to prevent compressor burnout and capillary tube plugging

Enhanced System Efficiency: Regulates fan ramp-up and ramp-down cycles to maximize latent heat removal and improve indoor air quality

Durable Construction: High-strength internal core maintains structural integrity even under high-velocity suction gas conditions

Manual Reset Feature: Ensures the system remains offline after a low-pressure event until a technician verifies gas line safety

Fenwal 35-605904-001 Control Freon Precise Manifold Regulation: maintains consistentThe Fenwal 35 605904 001 Control is a microprocessor based 24 VAC Direct Spark Ignition (DSI) module specifically engineered for high performance gas fired appliances, including special Heat N Glow fireplace systems. This ignition control module utilizes proprietary DETECT A FLAME technology to ensure precise flame sensing and rapid response to flame failure, typically within 0. 8 seconds. Designed to manage the complete operating sequence, the Fenwal
