The Fenwal 35-704600-001 is a microprocessor-based 120V Direct Spark Ignition (DSI) control engineered for high-performance gas-fired equipment

When your M556 pneumatic actuator fails to hold pressure or shows sluggish response

it provides the 5 VDC ratiometric signal necessary for the P266 controller to modulate motor speed on permanent split-capacitor (PSC) motors

This configuration is essential for liquid level control tasks such as high/low alarms and pump-up/pump-down sequencing

always diagnose the root cause of high-temperature trips before resetting the device to ensure continued furnace performance and reliable combustion cycles
