3. Appliance description
This appliance with full electronic control and output matching
keeps the outlet temperature constant. The water is heated by the
electronic control unit with motorised valve to precisely the select-
ed temperature. This occurs regardless of the inlet temperature.
DHW temperature
The DHW outlet temperature can be variably adjusted. The
selected temperature is displayed.
Heating system
The bare wire heating system has a pressure-tested copper casing.
The heating system is suitable for hard and soft water areas; it
has low susceptibility to scale build-up. This system ensures rapid
and efficient DHW availability.
Note
The appliance is equipped with an air detector that large-
ly prevents damage to the heating system. If, during op-
eration, air is drawn into the appliance, the heater shuts
down automatically for one minute, thereby protecting
the heating system.
Display backlighting
The display features two-tone backlighting (green/ amber).
Efficiency display
Green ECO backlighting indicates that the appliance is operating
in a particularly economical way
- when the output is less than 80%
- when the maximum output is less than 80% while the inlet
temperature is higher than 35°C
- when the maximum output is less than 80% while the ECO
function is switched on
Under all other operating conditions, the backlighting is amber.
Economy monitor
The appliance has an economy monitor. This is activated by press-
ing the appropriate key. Advertisements:
