Fig. 7: Schematics of a storage tank charging system

The controller begins charging the storage tank when the water temperature measured at
storage tank sensor 1 falls below the 'DHW temperature set point' by 0.1 °C. If the flow tem-
perature in the system exceeds the desired charging temperature, the controller tries to re-
duce the flow temperature in the heating circuit for up to three minutes before the exchanger
charging pump is activated together with the storage tank charging pump. When there is no
heating operation or when the flow temperature in the system is lower, the exchanger
charging pump is switched on immediately. If the temperature currently measured at storage
tank sensor 1 is reached at the flow sensor VF or after three minutes at the latest, the storage
tank charging pump is switched on. If a storage tank thermostat is used, the storage tank
charging pump is switched on when the temperature T = Charging temperature – 5 °C is
reached at the flow sensor VF.

The 'DHW temperature set point' is to be regarded in relation to the charging temperature if
a storage tank thermostat is used.

When the flow sensor VF4 is activated, the set point in the heat exchanger circuit is influ-
enced by the system deviation in the storage tank charging circuit upon activation of the stor-
age tank charging pump: if the temperature measured at flow sensor VF4 is lower than the
desired 'Charging temperature', the set point in the heat exchanger circuit is increased in
