High Quality 780-502 / DS845 Series Replacement 24V Direct Spark Ignition Control Module. 780-502 & DS845 Series. The 780-502 direct spark ignition control is designed as a direct replacement for Robertshaw 780 series intermittent pilot and direct ignition systems. It works with both standard and advanced flame sensing setups. When the thermostat calls for heat, the module provides a high-voltage spark to light the pilot or main burner. If a flame is not sensed within the allowed trial period, the module enters safety lockout to prevent unburned gas from accumulating. This specific module is a non-pre-purge unit, meaning it sparks immediately upon a call for heat without a delay blower cycle. It is universally applicable across a broad range of low-voltage (24 VAC) residential and light commercial gas systems, including gas-fired heating systems, commercial cooking equipment, water heating systems, and gas fireplaces. Built with durable housing for long-lasting performance, it is tested for durability with a high anti-interference margin and wide environmental tolerance. Includes: 1x Ignition Control Module, 2x Mounting Screws, and Double-Sided 3M Tape. (You will receive the exact part shown in the photos). ? PRO INSTALLATION TIP: Verify Your Voltage & Purge Settings! Ensure your system uses a 24 VAC power supply. This module is NOT compatible with line-voltage (120V) or millivolt systems. Additionally, do not use it in systems that explicitly require a pre-purge timing window for safety, as this board is designed for immediate spark. Diagnostic LED: An integrated LED indicator helps technicians quickly identify flame sense, spark, and system status. Versatile Flame Sensing: Supports both local (single-rod combination spark/sense) and remote (dual-rod separate spark and sense) configurations. Lockout Recovery: Features automatic lockout recovery to seamlessly manage safety sequences. Direct Plug-In: Plugs straight in with no wiring changes needed, saving time and cost on the job. Direct cross-reference replacement for the following OEM modules. Nationwide (OE Grade Direct Replacement). 24 VAC, 50/60 Hz. 250 AMP + Valve at 24 VAC. 1.5 AMP at.
