The electronically controlled small instantaneous water
heater maintains a constant outlet temperature up to its
output limit, irrespective of the inlet temperature.
This appliance has been factory-set to the outlet temper-
ature required for washing hands. Once this temperature
has been reached, the PCB automatically reduces the
output. The output is matched to the required tempera-
ture, this prevents the temperature being exceeded.
The appliance heats the water directly at the draw-off
point as soon as the tap is opened. The short pipe runs
ensure that energy and water losses are minimal.
The DHW output depends on the cold water temperature,
the heating output and the ow rate.
The bare wire heating system is suitable for hard and soft
water areas. This heating system has a low susceptibility
to scale build-up. The heating system ensures quick and
efcient DHW provision at the hand washbasin.
Your qualied contractor can adjust the maximum tem-
perature and ow rate (see chapter "Commissioning /
Settings").
Fitting the special aerator supplied provides an optimum
water jet.
