Robertshaw Hot Surface Ignition Control Module - Part# 780-783

Robershaw Hot Surface Ignition Control Module The 780 Series Hot Surface Ignition Modules are designed for use on gas fired heating systems. The system acts on a demand for heat by a switch or thermostat to supply power to the ignition control. On non pre-purge models, the ignitor will be energized immediately and remain on for either of two optional selected ignitor heat-up times approximately 17 or 34 seconds. For models with the prepurge option, there is a time delay equal to the heat-up time selected before the ignitor is energized. At the end of the ignitor heat-up time the gas valve is opened supplying gas to the main burner. After several seconds, the ignitor is turned off and the sensor is energized. As long as flame is sensed, the system continues to operate. When the thermostat is satisfied, the gas control will be closed to shut off the main burner. The 780 Series provides lockout and complete gas shut off if ignition is not proven after the trial for ignition sequences has been completed. To reset the system the thermostat or system switch must be opened for at least 10 seconds.
