/* Pompie software to control the pump of a pond
* (c) Marco Dumont
* This is completly "do what you like with it" sourcecode
* The pupose is a device that switches the pump to the filter, a natural swamp filter off ->
* when it is to hot >30 or to cold <0>
* The time the pump is on is limited - the plants need time to filter the nutrians, so fuzzy controls should be used.
* Another advantage is that this saves energy.
