4. Operation
The heating system of the appliance starts automatically and heats
the water as soon as you open the DHW valve at the tap.
Setting the DHW temperature
Should the outlet temperature fail to reach the required level with
the draw-off valve fully open, then more water flows through the
appliance than can be heated by the heating system.
f Reduce the flow rate with the draw-off valve.
Outlet capacities
Subject to season, different maximum mixed water or outlet ca-
pacities can result from varying cold water temperatures (see
chapter “Specification”).
Following an interruption of the water supply
See chapter “Restarting”
5. Cleaning, care and maintenance
f Never use abrasive or corrosive cleaning agents. A damp
cloth is sufficient for cleaning the appliance.
f Check the taps/valves regularly. You can remove limescale
deposits at the tap outlets using commercially available des-
caling agents.
6. Troubleshooting
Fault Cause Remedy
The appliance will not
start in spite of a fully
open DHW valve. There is no power.
Check the fuse/MCB in
your fuse box/distribu-
tion panel.
Starting volume is not
achieved. The jet control-
ler in the tap or shower
head is scaled up or con-
taminated. Clean and/or descale the
jet controller or shower
head.
The water supply has
been interrupted.
Vent the appliance and
the cold water inlet line
(see chapter “Commis-
sioning/ Restarting”).
Cold water flows briefly
while hot water is being
drawn. The air sensor detects air
in the water and briefly
switches the heater off. The appliance restarts
automatically after
1 minute.
If you cannot remedy the fault, notify your heating contractor. To
facilitate and speed up your enquiry, please provide the serial
