Always off : The DHW tank charge pump is switched
off permanently.
Exception for frost protection mode: The DHW tank
charging pump is activated if
- the outside temperature is <2°C, and
- the DHW tank temperature falls to <10°C.
Always on : The DHW tank charge pump is switched
on permanently. The pump is controlled taking the
parameters
Required temperature 1, Minimal tem-
perature and Hysteresis into account.
Time switches ( Monday-Sunday, daily , etc.): different
time ranges can be set, in which the DHW tank
charge pump is switched to
ON .

The operating mode Monday - Sunday is not
available if you are using the
mySOLARFOCUS app > 28 .
7.2 Fresh water module - FWM (optional)
A fresh water module heats domestic hot water in cir-
culation operation. The circulation pump of the fresh
water module starts if a DHW extraction point (also
called a
tapping point e.g. shower or bath) is opened.
The energy for heating up domestic hot water is taken
from the upper area (called the
DHW area ) of the buf-
fer tank.

Pump control
Always off : The fresh water module pump is per-
manently switched off; no domestic hot water is hea-
ted up.
Always on : (= manual mode); the fresh water module
pump is always switched on.
Automatic (= default setting), the fresh water module
pump starts when a flow is detected in the pipework
by an electronic sensor (e.g. the tap is opened at a
connected device).
Required DHW temperature
This parameter is only active for the release type
Automatic . The fresh water module regulates the tem-
perature at which the connected hot water devices
receive water to this temperature.
