9 Buffer tank

1 DHW tank temperature
Temperature is only visible when the buffer tank has been
selected as the energy source with existing hot water tank.
2 Buffer cylinder temperature top
3 Buffer cylinder temperature bottom
4 Temperature of heat source
5 Info line: Heating request (yes/no) to the
energy source
6 Info line: Request (yes/no) to the buffer tank
7 Buffer tank settings
The button is only visible when Time switching is selected
as the buffer tank operating mode. It may only be adjusted
by qualified personnel.
8 Buffer tank status line
9 Status, buffer charging pump
On the first buffer tank whose energy source is the boiler,
the status of the return booster pump is displayed here.

9.1 Setting the buffer tank temperatures

MinimumBuffer cylinder temperature top
When Buffer cylinder temperature top falls below this
value, the energy source for the buffer cylinder starts
(e.g. boiler) and the buffer cylinder is re-charged
(upon time release). Recommendation: 30°C
Operation manual ecotop-zero, ecotop-light
Maximum buffer cylinder temperature bottom
The buffer tank is charged until the Buffer cylinder
temperature bottom has reached this value. Recom-
mendation: 60°C
i
In order to ensure optimum and efficient use of
the buffer tank, the difference between these
two temperatures should be >15°C.
The minimum buffer cylinder temperature top
must always be smaller than the maximum buf-
fer cylinder temperature bottom.
