If the user lowers the set temperature during the operation of the anti-legionella

Error indication
In case of an error or warning on the heater, red and green light start blinking to
indicate an error according to the table below.
When the water heater is not in use for a longer period of time and is switched off or
disconnected from the power supply, it must be emptied in case of danger of
freezing. Water from the heater is drained through the inlet pipe of the heater. For this
purpose, a special fitting (T-fitting) must be mounted between the relief valve and the
heater inlet pipe, or a discharge tap. The heater can be discharged directly through
the relief valve, by rotating the handle or the rotating valve cap to the same position
as for checking the operation. Before discharge, make sure the heater is
disconnected from the power supply, and open the hot water on the connected mixer
tap. After discharging through the inlet pipe, there is still some water left in the water
heater. The remaining water will be discharged after removing the heating flange,
through the heating flange opening.
The external parts of the water heater can be cleaned with a mild detergent solution.
Do not use solvents and abrasives.
Regular preventive maintenance inspections ensure faultless performance and long
life of your heater. The first of these inspections should be carried out by the
authorised maintenance service provider about two years from installation in order to
inspect the wear of the protective anticorrosion anode and remove the lime coating
