Robertshaw 780-785 Hot Surface Ignition Control, I.C.U.

The Robertshaw 780 Series hot surface controls are designed for use on gas fired 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 igniter will be energized immediately and remain on for either of two optional selected igniter heat-up times: approximately 17 or 34 seconds. For models with the prep urge option, there is a time delay equal to the heat-up time selected before the igniter is energized. At the end of the igniter heat-up time, the gas Valve is opened supplying gas to the main burner. After several seconds, the igniter is turned off and the sensor is energized. As long as flame is sensed, the system continues to operate. made in United States. Manufactured by Robertshaw controls company.
