Aftercompletingthecylinder heating(thecylinderhasreached
the set temperature), the cylinder primary pump willrun on up
to the maximum set run-on time. The cylinder primary pump
willswitchOFFprematurelyif,duringtherun-ontime,theboiler
watertemperaturehasfallentoadifferentialbetweenboilerand
cylinderwatertemperature of5K,topreventtheboilercooling
downtooseverely.

Cylinderheatingcommencesassoonasthecylindertemperature
sensor demands heat. The heating circuit pump would be
constantlyswitchedOFF,iftheboilerwasundersized,thecylinder
wasscaled-uporifDHWwasconstantlydrawnoffduringDHW
