2.8.1 Metering via tank (export version)
The scale inhibitor is metered in accordance with
the setting at the Service switch. The setting is
described under 2.6 Service switch. Metering
takes place in Program switch position „Eco"
and „Hot Water" only, at a water temperature set
to 50 °C.
The empty signal is sent via the level sensor (4)
and is displayed by means of the indicator light
or display.
Burner operation is possible even without scale
inhibitor. However, if the water is hard (contains
calcium carbonate), faults due to scale deposits
are to be expected.
Note
The metering may not be switched off if
using RM 111 (see Chapter 2.6).
