Legend:
WARNING: If the temperature of the additional heating source drops and the
circulation of water through the heat transmitter is enabled the heat can
uncontrollably be taken from the water tank. When attaching the appliance to other
heating sources, the additional source temperature must be properly regulated.
WARNING: In case of connecting solar panels as an external source of heat, the
operation of the aggregate of the heating pump must be turned off. A combination of
those two sources can lead to overheating of the domestic water, resulting in
excessively high pressures.
