Grumman sunstream questions

Posted by Tom Beland on January 13th, 2003 01:58 PM

I have a Grumman sunstream solar system installed on my house and the control panel does not work.
When i leave it on "auto" it never shuts off. I tried to contact Grumman but they sold that product line off many years ago so they could not help me. I was looking for a wiring diagram or info on picking up a replacement controller. I have bought a a Goldline GL30G but I would like to see a wiring diagram before I retrofit this unit into my system. The original controller also wired the two circ. pumps separately, should I worry about wiring them both together with the new controller or not?
