2nd all that. I would add that since you want all this to run array direct, you need to be VERY aware of the MAX voltage of both the relay and contacts that the switch can handle. If it's a summer only gig, you can probably go with Voc. On Jun 23, 2014, at 6:14 AM, Allan Sindelar wrote: Agree w

Agree with Jerry on using the float switch circuit. The one note I would add is that the Grundfos CU200 "controller" uses a conventional close-on-rise signal algorithm. So a timer would have to be set in reverse - that is, an "on" closed-contact signal from the ti

Is there a water level switch? I would use that to turn it off. On Sun, Jun 22, 2014 at 6:37 PM, All Solar, Inc. wrote: > I am in need of a timer for an SQF Grundfos pump, PV direct. > Would it be considered a non-inductive load? > I was thinking to install the timer on the PV input side. > >

I am in need of a timer for an SQF Grundfos pump, PV direct. Would it be considered a non-inductive load? I was thinking to install the timer on the PV input side. Jeremy Rodriguez, President All Solar, Inc. 1463 M Penrose Colorado 81240 719-372-3808 office 719-372-3804 fax www.asolarelectric
