7.9 Forced charging of DHW storage tank
To provide the full network performance for room heating when the time-of-use of the heat-
ing circuits begins, any storage tanks are charged one hour before the time-of-use of the
heating circuits 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 deactiva-
tion value of T = 'DHW temperature' + 'Hysteresis'.
The forced charging of the storage tank does not take place when the DHW circuit is not
used at the beginning of the time-of-use set for the heating circuit(s).
This function is not available when a storage tank thermostat is used.
7.10 Thermal disinfection of DHW storage tank
In all systems with DHW heating, a thermal disinfection is performed on a selected day of
the week or daily.
− In systems with DHW storage tank, it is heated up, taking into account the Charging tem-
perature boost parameter (or Set point boost, depending on the system) to the adjusted
Disinfection temperature. Disinfection takes place within the adjusted time period ('Time').
− In systems with DHW heating in instantaneous heating system, the function remains ac-
tive taking into account the Boost parameter until the circulation pipe, measured at stor-
age tank sensor 1, has reached the adjusted Disinfection temperature, provided disinfec-
tion has not been terminated prematurely at the end of the adjusted time period (Time).
The 'Duration' determines how long the disinfection temperature must be maintained within
the adjusted time period to rate the process successful. If the Duration is set to a value other
than 0, no intermediate heating operation takes place during thermal disinfection.
When the 'Disinfection temperature' has not been reached before the end of the thermal dis-
infection cycle, it is indicated correspondingly on the display. This error message can also be
