Hi everyone
So my old controller died. It was the controller that came w my solar water heater. I switched to a new controller and the backup heating element won't come on. It says in the manual to use an SR802 relay which I don't have so am not using. I am wondering with this new controller how to get the backup heating element to come on without this sr802 relay...thanks
