Functions of the DHW circuit
Note!
Instead of the DHW temperature parameter, the Charging temperature can be set as the ab-
solute value at the rotary switch if a storage tank thermostat is used.
Stop storage tank charging
The controller stops charging the storage tank when the water temperature measured at sen-
sor SS1 has reached the temperature T = DHW temperature + hysteresis .
When there is no heating operation or when the flow temperature demand in the system is
lower, the corresponding valve is closed.
The storage tank charging pump is switched off when the limit temperature for Stop charging
has been reached, at the latest, however, after approx. 3 minutes.
The default setting of this function causes the storage tank to be charged by 5 °C to 60 °C
when the storage tank temperature falls below 55 °C. The charging temperature is calculated
from the DHW temperature (55 °C) plus the charging temperature boost (10 °C), which
equals 65 °C. When the storage tank has been charged, the heating valve is closed and the
charging pump continues operation until the charging temperature falls below 53 °C. Out-
side the times-of-use, the storage tank is only charged when the temperature falls below
40 °C ( Sustained DHW temperature ). In this case, the tank is charged with a charging tem-
perature of 50 °C until 45 °C are reached in the tank.
