Danger!
Danger of scalding!
The units are equipped with an automatic Legi-
onella protection switching system: If the tem-
perature in the hot water tank falls below
50 °C, the tank is heated up to 70 °C once
every 24 hours. In this case there is a danger
of scalding when drawing the water off.
The Legionella protection system can be de-activated in
the diagnosis level. For further information see installati-
on and maintenance manual, Section 6.1.4, Storage tank
charging and Section 8.1.2, Diagnostic codes.
