Can I restarting my heater with EGC 1 control board?

I think you can or is this a trick question? If your asking how to reset the control board turn the breaker off going to the system for a few seconds and then back on.

Lol,, trick question,, would be nice if we were given more details as to what you are talking about and the name and model of your equipment,, then someone can maybe help you
