Appliance description
3. Appliance description
The electronically controlled mini 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 temperature
required for washing hands. Once this temperature has been
reached, the PCB automatically reduces the output. The output is
matched to the required temperature, this prevents the temper-
ature 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 heat-
ing output and the flow 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 efficient DHW provision
at the hand washbasin.
Your qualified contractor can adjust the maximum temperature
and flow rate (see chapter "Installation / Commissioning / Set-
tings").
4. Settings
The appliance heating system switches on automatically as soon
as you open the DHW valve at the tap or activate the sensor of a
sensor tap. The water is heated. The water temperature can be
adjusted at the tap.
For initial flow rate and flow rate limiting, see chapter "Installa-
tion / Specification".
Following an interruption to the water supply
See chapter "Installation / Commissioning / Restarting".
5. Cleaning, care and maintenance
