Robertshaw 780-715 Ignition Module

The Robertshaw 780-715 Ignition Module is a veteran field-service solution for intermittent pilot ignition systems. This nonlockout ignition module utilizes sophisticated flame rectification technology with solid-state logic to provide stable automatic sequencing for gas-fired appliances. As a direct 62-21747-02 replacement and a standard cross for 100108736 and SP715A, this control manages the 24V AC circuit, simultaneously initiating spark and opening the pilot valve. Upon sensing the pilot flame, it terminates sparking and energizes the main valve. In the event of flame failure, the 780-715 immediately closes the main gas valve and restarts the ignition sequence to ensure continuous operation without manual intervention. Its compact footprint and molded-in terminal barriers make it a preferred HVAC replacement part for minimizing truck stock while maintaining compatibility with 7000 BDER, 7100 DER, and 7200IPER gas valves in both local and remote sense configurations.

• Direct Replacement: Seamlessly drops into systems requiring Robertshaw 780-715, 62-21747-02, and 100108736, reducing installation time.
• Non-Lockout Logic: Automatically recycles the ignition sequence upon flame loss, ideal for critical heating applications where manual resets are impractical.
• Universal Compatibility: Supports both single-rod (local) and two-rod (remote) flame sensing setups.
• Durable Construction: Rated for ambient temperatures from -40°F to 175°F with a moisture-resistant design for high-humidity environments.
• Solid-State Monitoring: Continuously monitors the pilot burner flame at a synchronous frequency to prevent main valve operation without a proven flame.

Is the 780-715 compatible with LP (Propane) gas?
No, as a nonlockout module, the 780-715 is generally designated for use with Natural Gas per manufacturer safety standards. Always verify the specific appliance rating plate before installation.

What is the spark rate for this module?
This unit delivers a consistent spark rate of 3 to 4 sparks per second to ensure rapid pilot ignition.

Can I use this to replace a lockout-style module?
No. Do not replace a lockout module with a non-lockout version like the 780-715, as this may violate local safety codes and change the intended sequence of operation for the equipment.
