Okay to turn off pump when I have solar hot water?

[Justin]

Thanks everyone, and I will call Drainpipe. I should have mentioned that I have a separate electric pump that theoretically cycles the water between the panels and the tank when the water gets too warm, so my thought (hope) was that this could just cycle the whole time I am gone, irrespective of whether the water pump is on. But I'll check with Drainpipe to make sure.
