10.3.5 Quick charge
Uses a higher loading temperature to load the upper region of the storage
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
first-priority 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 charge 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 11, p. 45 (P18, P19).
