Robertshaw 785-002 Pilot Control

The Robertshaw 785-002 is a specialized 9VDC pilot relight control engineered specifically for mobile platforms like recreational vehicles (RVs) and remote commercial heating equipment where AC power is unavailable. This solid-state automatic pilot ignition system provides a reliable 15kV high-voltage spark to ensure constant pilot flame presence in water heaters, furnaces, and rooftop units. Operable across a wide temperature range of -40°F to 185°F, this control maintains a precise 1/8" spark gap to eliminate downtime caused by nuisance pilot outages due to drafts or high-wind conditions. The 785-002 kit includes the essential ignitor and reset button assembly, designed for seamless integration with existing safety-certified pilot gas valves. By monitoring the flame via a dedicated 10-395 electrode assembly, the module initiates sparking the moment a flame failure is detected, maintaining system continuity without requiring manual intervention or external 110V/24V wiring.

• DC Power Versatility: Runs on a standard 9-volt DC supply, making it ideal for battery-dependent RV systems and off-grid appliances.
• High-Temperature Reliability: Engineered to withstand harsh environments with a thermal rating up to 185°F (85°C).
• Instantaneous Relighting: Features a high-intensity 15kV output to quickly stabilize RV pilot flames during environmental fluctuations.
• Universal Compatibility: Serves as a direct replacement for various Uni-Line, Camstat, and White-Rodgers series relight modules.

Does this unit include the battery for operation?
No, the Robertshaw 785-002 requires a 9V DC battery which must be purchased separately. Veteran technicians typically recommend high-quality lithium batteries for better performance in cold weather.

Can this be used on residential 120V boilers?
This specific model is the 9VDC version. If you are working on a standard residential 24V or 120V system, the 785-001 model is the appropriate alternative for AC-powered applications.

What should I do if the sparking doesn't stop after the pilot light is on?
Check the ground wire connection and ensure the 10-395 electrode is properly positioned within the flame. Ensure there is no carbon buildup and the spark gap is set to the technical specification of 1/8".
