Affix a label in the operating instructions.
Calling up the commissioning assistant at a later
point
If you need to continue commissioning later, the com-
missioning assistant can be reactivated at any time.
Filling the heating system
Fill water
According to EN 1717 with DIN 1988-100, as a heat
transfer medium for DHW heating, the heating water
must meet fluid category ≤ 3. This requirement is met if
water of potable quality is used as heating water. For
example, if additives are used, the additive manufac-
turer must specify which category the treated heating
water comes under.

Please note
Unsuitable fill water increases the level of
deposits and corrosion and may lead to appli-
ance damage.
Flush the heating system thoroughly before
■
filling.
Only use fill water of potable water quality.
■
■
Special antifreeze suitable for heating systems
can be added to the fill water. The antifreeze
manufacturer must verify its suitability.
■
Fill and top-up water with a water hardness in
excess of the following values must be soft-
ened, e.g. with a small softening system for
heating water.
