Ah yes, I didn't know they were available. The only installation I've looked closely at in USA had pairs of circuit breakers with a small metal bar between them so that in theory they would trip together. Except one pair which didn't have the pole. But that's okay because it only fed a heat...
If you have a battery powered car which is charged at home then a heater could be run off of the incoming mains supply to pre-heat the car at a higher power level than during battery operation. It could even be set to never let the car get below freezing.
If the house has a split-phase supply then 240v is available. This is commonly used for driers, ranges, dish washers and large pumps.
It would be possible to connect the light to 240v, but this would require two circuit breakers (one on each part of the split-phase supply), red and black wires...
Between 31759 and 00000 is 32767, or binary 0111 1111 1111 1111. This happens to be the maximum value for a 16-bit signed integer. Adding 1 to that would cause it to loop back to 0. Just a thought, may be coincidence.
