OPERATION

GENERAL

3. General
The tankless water heater differs from conventional storage type
water heaters in several ways. It does not store hot water. Instead,
water is heated instantaneously as it fl ows through the appliance.
Due to the absence of stand-by losses, the appliance offers greater
energy effi ciency than storage type water heaters.
The input of heat into the water is electronically controlled. The
appliance will deliver any water temperature between 86 °F (30
°C) and 140 °F (60 °C). Please set the desired temperature using
the knob on the front cover.
Note
For reasons of appliance effi ciency and durability (sca-
ling), the optimum temperature setting lies between 86°F
(30°C) and 120°F (50°C).
In case the "Power" light is fl ashing while the appliance operates,
the water fl ow rate exceeds the heating capacity of the appli-
ance. Reduce the hot water fl ow rate in order to let the appliance
achieve the set point temperature. The maximum temperature is
electronically limited to 140 °F (60 °C). In case you have questions
regarding the way you plan to use the appliance, please call our
technical service line, see last side.
