The collector pump is activated whenever the temperature acquired by the collector
sensor rises.
To ensure that the flow pipe from the collector to the storage tank also receives hotter
water, deactivation of the collector pump after reaching the frost protection threshold at
the collector sensor is delayed by the minimum running time.
