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)

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 fol-
lowing circumstances.
■ On their way between transmitter and receiver, wire-
less signals are damped, e.g. by air or when pene-
trating walls.
Wireless signals are reflected by metallic objects
■
e.g. reinforcements embedded in walls, metal foil of
thermal insulation and thermal glazing with metal-
lised 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 dis-
tance of at least 2 m from these devices:
– Computers
– Audio and video systems
– Devices with active WiFi connection
– Electronic transformers
Pre-ballasts
–

Angle of penetration

The reception quality remains best if radio 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.

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.
Install the heat generator as close as possible to the
WiFi router to ensure a good WiFi connection. The sig-
nal strength can be displayed on the heat generator
(see the operating instructions).
Note
The WiFi signal strength can be increased with com-
mercially available WiFi repeaters.
