Functions of the DHW circuit

6 Functions of the DHW circuit
a)
Fig. 6 · DHW system in a storage tank charging system (a) and in a storage tank system (b)
The controller starts charging the storage tank as soon as the water temperature measured
at the storage tank sensor (S5 or S2) falls below the DHW set point (P16).
The charging of the storage tank finishes when the water temperature measured at the stor-
age tank sensor has reached the temperature T = DHW set point + On/off differential of
storage tank charging.
Use F8 to select the On/off differential of storage tank charging .

DHW priority

Should the temperature at the DHW sensor S4 or, in cases where DHW sensor S4 does not
exist, at the storage tank sensor S5/S2, fall below the Monitoring value for priority for five
minutes, the heating capacity of the heating circuit is lowered by reducing the set point. The
heating circuit set point is then reduced in small steps every five minutes up to a minimum
