6.10 Forced charging of the DHW storage tank (Anl 2, 3, 5, 7, 8 and 9)
This function is always configured when the system has at least one storage tank sensor.
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 circuits
starts.
6.11 Thermal disinfection of the DHW storage tank
In all systems with DHW heating, the DHW storage tank is thermally disinfected on a selected
day of the week or every day. The storage tank is heated up to 70 °C. Thermal disinfection starts
at 0.00h and finishes at 4.00h at the latest.
Thermal disinfection for preventing legionella infection causes
4
high return flow temperatures during the disinfection cycle (return flow temperature limita-
tion suspended),
4
high storage temperatures after thermal disinfection has been concluded,
4
lime scale (possibly), which can have a negative effect on heat exchanger performance.
Note!
This function is not available when a storage tank thermostat is used.
