Forced charging of the DHW storage tank

To provide the full room heating performance when the time-of-use of the heating circuits be-
gins, existing storage tanks are charged one hour before the time-of-use of the heating cir-
cuits starts. For the individual controller, this means that storage tank charging is activated
when the water temperature in the storage tank falls below the adjusted deactivation value of
T = DHW temperature + hysteresis . The forced charging of the storage tank does not occur
when the DHW circuit is not used at the beginning of the time-of-use set for the heating cir-
cuit.
Note! This function is not available when a storage tank thermostat is used.

Thermal disinfection of the DHW storage tank

In all systems with DHW storage tank, the DHW storage tank is thermally disinfected on a
selected Day of the week or every day.
The tank is heated up to the adjusted Disinfection temperature , taking into account the
Charging temperature boost . Disinfection begins at the adjusted Start time and, at the latest,
ends at the specified Stop time set in CO2 -> F20 - 0. In case of the Time-controlled thermal
disinfection (CO2 -> F20 - 1), the disinfection remains active even after the Disinfection tem-
perature is reached and ends at the adjusted Stop time .
In addition to this function or instead of it, the thermal disinfection can be activated by a bi-
nary input. The binary input, which initates the thermal disinfection process, functions either
as a momentary-action switch or a latching-action switch:
4
Functioning as a momentary-action swtich, the floating switch at input RS leads to the
next programmed thermal disinfection running right through from the Start time to the
Stop time .
4
Functioning as a latching-action switch, a closed contact of the floating switch at input RS
leads to the thermal disinfection being active until the contact is opened again.
