Description
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 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.
