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 firmware
update.
Do not use unencrypted connections between the
boiler and the WiFi router.
Internet connection with high availability:

Flat rate (flat rate tariff without restriction on time or
data volume)
Dynamic IP addressing (DHCP, factory setting) 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 network

(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.
Wireless signal range of WiFi connection
The range of wireless signals may be reduced by walls,
ceilings and interior fixtures. These weaken the wireless
signal, causing poor reception due to the following
circumstances.
On their way between transmitter and receiver,

wireless signals are damped, e.g. by air or when
penetrating walls.
Wireless signals are reflected by metallic objects,

e.g. reinforcements embedded in walls, metal foil of
thermal insulation and thermal glazing with
metallized thermal vapour deposit.
Wireless signals are isolated by service ducts and

lift shafts.
Wireless signals are disrupted by devices that also

operate with high frequency signals. Maintain a
distance of at least 6 ft (2 m) from these devices:
– Computers
– Audio and video systems
– Devices with active WiFi connection
– Electronic transformers
– Pre-ballasts
Install the boiler as close as possible to the WiFi router to
ensure a good WiFi connection. The signal strength can
be displayed on the boiler (see the operating instructions).
Note: The WiFi signal strength can be increased with
commercially available WiFi repeaters.
Angle of penetration
The reception quality remains best if wireless signals
hit the walls vertically.
Depending on the angle of penetration, the effective
wall thickness changes and so does the extent to which
the electromagnetic waves are damped.
