DHW heating
The burner and the circulation pump for
cylinder heating are started if the cylinder
temperature lies 2.5 K below the set cyl-
inder temperature.
In the delivered condition, the set boiler
water temperature is 20 K higher than
the set DHW temperature (adjustable via
coding address "60"). The burner will be
switched OFF and the circulation pump
run-on time will begin, if the actual cylin-
der temperature exceeds the set cylinder
temperature by 2.5 K.
