Electrical connections
Danger
The absence of system component earthing can
lead to serious injury from electric current if an
electrical fault occurs.
The appliance and pipework must be connected
to the equipotential bonding of the building.
Routing connecting cables/leads
!
Please note
If closures or diaphragm grommets are dam-
aged, splashproofing is no longer ensured.
Never open or damage closures or unused dia-
phragm grommets on the underside of the appli-
ance. Seal cable entries with fitted diaphragm
grommets.

WiFi operational reliability and system requirements
WiFi router system requirement
WiFi router with activated WiFi:
■
The WiFi router must be protected by a sufficiently
secure WPA2 password.
The WiFi router must always have the latest firm-
ware update.
Do not use unencrypted connections between the
heat generator and the WiFi router.
Internet connection with high availability:
■
Flat rate (flat rate tariff without restriction on time or
data volume)
28
(cont.)
Bundle cables using the supplied cable clips.
Route extra low voltage (ELV) leads < 42 V separately
from cables
42 V/230 V~.
>
Secure the cable clips on the underside using the sup-
plied screws.
Do not route cables/leads over sharp edges and lying
against the casing (sound transmission).
!
Please note
If connecting cables/leads come into contact
with hot components, they will be damaged.
When routing and securing cables/leads on site,
ensure that the maximum permissible tempera-
tures for these cables/leads are not exceeded.
Dynamic IP addressing (DHCP, delivered condition)
■
in the network (WiFi):
Have this checked on site, and if required set up, by
an IT expert prior to commissioning.
■
Set routing and security parameters in the IP net-
work (LAN):
Enable port 80, port 123, port 443 and port 8883 for
direct outward connections.
Have this checked and, if necessary, set up on site
by an IT expert before commissioning.
