Commissioning, inspection, maintenance
Commissioning the system
Switching WiFi ON/OFF
The appliance is equipped with an integrated WiFi
communication module with extended type plate.
The internal communication module supports commis-
sioning of the heat generator with the "Vitoguide app",
connectivity with the "ViCare app" and the connection
to the "Vitoguide" digital service centre.
The access details required for establishing a connec-
tion are recorded in the form of an access code with
"WiFi symbol". Three copies of this code are located
on the rear of the programming unit.
Before installing the programming unit, remove the
access code labels from the rear. For commissioning,
affix one label to the space marked out on the type
plate.
Switch on the WiFi connection and establish a connec-
tion to the router; see also page 28.
Note
If "E10" is displayed, the connection to the home net-
work could not be established. Check the router and
the network password.
If "E12" is displayed, the connection to the server
could not be established. Re-establish the connection
at a later time.

Filling the heating system

According to EN 1717, as a heat transfer medium for
DHW heating, the heating water must meet fluid cate-
gory ≤ 3. This requirement is met if water of potable
quality is used as heating water. For example, if addi-
tives are used, the additive manufacturer 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 fill with water of potable quality.
Fill water with a hardness above 300 ppm
■
must be softened.
■ Special antifreeze suitable for heating systems
can be added to the fill water. The antifreeze
manufacturer must verify its suitability.
