System safety:
■
When connecting the remote control to the power
supply, only use the plug-in power supply unit provi-
ded or the power supply unit for flush mounting.
■
The heating system and the functionality of the mes-
sage paths must be tested at regular intervals.
■
To improve the operational reliability of the heating
system, we recommend implementing supplemen-
tary measures, e.g. frost protection or monitoring for
water damage.
System requirements for a reliable WiFi internet
connection:
■
WiFi router with activated WiFi:
The WiFi router must be protected by a sufficiently
secure WPA2 password.
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)
■
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.
Reliable remote control operation:
■
The heat generator control unit
and
the
Vitotrol 300-E remote control must be connected via
low power radio.
■
At least 1 heating circuit must be assigned to the
remote control (settings to be input by the contractor
at the control unit of the heat generator).
■
Commissioning has been carried out.
■
The remote control's full range of functions is only
available if the software is up to date:
To enable software updates, the heat generator has
to be connected to the internet via a WiFi router. The
download always takes place via the Viessmann
server.
Automatic software updates only occur if a perma-
nent internet connection is provided via the heat gen-
erator (recommendation).
Settings for WiFi and low power radio at the
heat generator:

Liability
No liability is accepted for loss of profit, unattained
savings, or other direct or indirect consequential losses
resulting from use of the Vitotrol 300-E, the Viessmann
server or the software, or for damage resulting from
inappropriate use.
Liability is limited to typical damage arising if a funda-
mental contractual obligation is violated through slight
negligence, the fulfilment of which is essential for
proper execution of the contract.
The limitation of liability shall not apply if the damage
was caused deliberately or through gross negligence,
or if mandatory liability applies due to product liability
legislation.
The Viessmann General Terms and Conditions apply,
which are included in each current Viessmann pricelist.
Viessmann accepts no liability for push notifications
and email services, which are provided by network
operators. The terms and conditions of the relevant
network operators apply in this context.
