Pump control
Always off: The fresh water module pump is switched
off permanently. The hot water is not heated.
Always on: (= manual mode) The fresh water module
pump is always switched on.
Automatic: (= default setting) The fresh water mod-
ule pump starts when a flow is detected in the pipe-
work by an electronic sensor (e.g. the tap of a
connected device is opened).
Pump output value
A manual entry for the pump speed is made here with
the setting "Always on". This value is visible only in
the service menu.
Required DHW temperature
This parameter is active only 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. It is visible in the
fresh water module screen
temperature.
Controller active on circulation
When the parameter is active, the fresh water module
pump and the recirculation pump start at the same
time. This is helpful where recirculation pumps or
lines have insufficient dimensions so that the required
flow is reached to trigger the flow sensor.
Name
An individual name for the fresh water module can be

tapping points, e.g. basin, shower, bath, etc.), even
with long supply pipes.
Recirculation control is possible with a fresh water
module or for a DHW tank.
