The buffer tanks with direct loading and unloading can take varying forms depending on the system
schematic selected.
On the separate pages, the inlets and outlets of the different piping pairs for loading and unloading the
tank as well as the respective specific losses of the piping inlets and the installation height of the
temperature sensors are displayed but cannot be modified.
On the Lower Collector Loading (buffer tank with auxiliary heating) or Upper Collector Loading (buffer
tank without auxiliary heating) pages, only the maximum tank temperature may be entered.
No changes can be made on the Dual Coil Auxiliary Heating page.
On the Cont. Auxiliary Heating page, the desired tank temperature for the auxiliary heating is defined
and entered in relation to the desired tank temperature for the switch-on / switch-off temperatures of
the boiler.
If you activate the Fixed field, you can predetermine the target temperature in the buffer tank. On
activating the Accept field, the buffer tank target temperature, depending on operating state and
requirements, is either the temperature required to load the water heater or for supplying the heating
loop.
In the limited operating times field, the auxiliary heating of the tank can be cut off for specific times of
the day.
The Flow page specifies the connections for unloading the tank.
