Taco 007e installation with flanges 

Solid orange light is normal operation. When there is a quick flash to white then back to orange, it means it went into SureStart mode and noticed that there was air in the volute of the circulator

Hi Dave thank you for the video. What does it mean when the light went off after working fine?

@@cesarmji the motor I show in the video is a standard off the shelf production except for the switch. The lights go out when the power is removed or the the call for heat is satisfied
