11.3.4 Quick charge
Uses a higher loading temperature to load the upper region of the stor-
age tank more quickly in order to provide early prevention of back-up
heating by the conventional heating system. To do this, the loading
strategy of the storage tank is changed from differential loading to
absolute temperature loading as soon as the temperature in the upper
tank region drops below T
on
*)
. At the same time, an attempt is made to
achieve a higher temperature in the storage tank by using the speed
control.
*)
To retain the proven quick charging functionality , when T
on
is changed the value
of T
off
is changed in parallel.
Note
To use the quick charge function, the speed control must be switched
on; more information on this is provided in Section 12, p. 39 (P08).
