I did that before I posted but I didn't find one that met the NH rules.

I think Heath's hardware sells the signs as do probably most of the hardware stores around the lake. Temperature is not a bad way to run it although will probably run too much at the beginning of winter and not enough near the end when 32 will bring pretty rapid freezing especially at night. I find that pretty much below 15 to 20 degrees daytime temps that I need to run it all day. Obviously you don't need to run until ice in.

Stupid question:
Does the water have to be circulating to "prevent" the ice from forming or does the process of moving warmer water under the ice melt it?

Less Stupid question:
How do you deal with GFI breaker tripping on such a mission critical process?

I believe it is actually the combination of both, the fact that the water is a bit warmer and that it's moving (agitation) that does the job the most efficiently.

Personally, I would not use a GFI protected circut or outlet for that very reason and I don't care what the safety police think. The breaker you might be ok with but the outlets are just to sensitive and are prone to failure.
