3. Appliance description
The appliance constantly keeps the water content avail-
able at the preselected temperature.
The DHW outlet temperature can be variably adjusted
at the temperature selector. The output is switched on
automatically as soon as the appliance temperature falls
below the selected value.
– Pressurised connection:
The appliance is under mains water pressure. The
volume of water expands as the water heats up. Dur -
ing this process, expansion water drips through the
safety valve. This is a necessary and normal pro -
cess.
– Unpressurised connection:
The volume of water expands as the water heats up.
Expansion water drips through the tap outlet. This
is a necessary and normal process.
