Setting the maximum hot water temperature
• Set the maximum hot water temperature limit by changing parameter [4].
Setting the energy-saving hot water temperature
In order to minimise standby losses relating to the hot water storage tank, yet still maintain a comfortable minimum hot water
temperature, it is possible to set a temperature which the hot water storage tank must not fall below during economy mode
phases.
• Set the energy-saving hot water temperature by changing parameter [7].
6.6.8 Setting the maximum flow temperature
The flow temperature is the temperature the water is heated to before it is introduced into the heating circuit. Each heating circuit
has its own maximum flow temperature.
• Set the maximum flow temperature by changing the relevant parameter (see Table 6-9).

Hot water circuit
Tab. 6-10 Dependencies between flow temperatures and the hot water circuit
CAUTION:
If the Legionella protection function is activated, the hot water temperature may temporarily exceed 65 °C.
• If hot water is required during the disinfection phase, it must be mixed with cold water.
If the ST/OT contact is open, this temperature is maintained (only applies to automatic programmes 1 – 3 and
"reduced heating mode").
