Uses a higher loading temperature to load the 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
made to achieve a higher temperature in the storage tank by using the
speed control.

Note
To use the quick charge function, the speed control must be
switched on; more information on this is provided in Section 10,

Calculates the acquired heat volume based on the following information:
• Supply temperature
• Return temperature
• Flow rate volume determined via calculations based on the pump
speed or by pulse water meter measurements (terminal 5).
Note
Calculation based on the pump speed cannot be performed
when No system (system 0.1) has been selected.
