The Vitoconnect enables communication via the inter-
net between the following components and the
Viessmann server:
■Vitotronic control unit (Optolink interface)
■Heat generator with OpenTherm interface
■ViCare components for individual room control (with-
out connection to the heat generator, e.g. for rental
apartments)
The full range of functions is only available if the fol-
lowing conditions are met:
■The Vitotronic control units, the heat generator with
OpenTherm interface and the Vitoconnect must be
connected and configured correctly.
■The Vitoconnect is connected to the internet via its
WiFi router.
■Internet access must be available at all times.
■User registration has been carried out.
■To ensure that messages can still be sent if there is a
power failure, we recommend connecting the
Vitoconnect and WiFi router to the power supply via
an uninterruptible power supply.
Note
■The heating system and the functionality of the mes-
sage paths must be tested at regular intervals.
■To further improve the operational reliability of the
heating system, we recommend allowing for supple-
mentary measures, e.g. frost protection or monitoring
for water damage.
Liability
No liability is accepted for lost profit, missed savings,
or other direct or indirect consequential damage that
arises from the use of Vitoconnect, the Viessmann
server or the software, as well as for damage from
incorrect use.
In the event of any slightly negligent violation of sub-
stantial contractual obligations which are deemed
essential for the purpose of complying with the subject
matter of the contract, liability is limited to damage typi-
cal for the contract.
The limitation of liability is not applicable if the dam-
ages were caused deliberately or with gross negli-
gence or if there is mandatory liability according to the
law on product liability.
Viessmann's General Terms and Conditions of Sale of
apply; the latest version of these terms and conditions
is included in the current Viessmann price list.
The relevant data protection regulations and terms of
use apply to the use of ViCare or ViGuide.
Push notifications and e-mail services are services
provided by network operators for which Viessmann
does not accept any liability. In this respect the terms
and conditions issued by the relevant network operator
apply.

Vitoconnect products are designed for operation in
buildings used for residential and business purposes
only. Misuse of the appliances is prohibited and will
result in exclusion of liability (e.g. commercial or indus-
trial use for a purpose other than for control and regu-
lation).
Compliance is required with the installation, service
and operating instructions supplied with the product
and provided online.
Vitoconnect products are to be used exclusively for
monitoring, operation and optimisation of the systems,
using the user and communications interfaces defined
in the printed material of the product. For the commu-
nications interfaces, it must be ensured on-site that for
all the transmission media used, the system require-
ments defined in the product documents are met at all
times (e.g. the required Wi-Fi connection to a Wi-Fi
router).
For voltage supply, only the components specified for
this purpose may be used (e.g. wall power supplies).
Note
The appliances are designed exclusively for domestic
or domestic-like use, i.e. even uninstructed persons
can safely operate them.
Product information
Vitoconnect is a wall-mounted Internet interface that
communicates with the boiler control unit of the heat
generators.
The Vitoconnect enables remote control of heating
systems via the internet. Settings and checks are
made via the ViCare app.
Alternatively, the heating system can be controlled
remotely by the contractor using ViGuide.
Vitoconnect, type OPTO2
The Vitoconnect, type OPTO2, can be used for single
boiler systems with an Optolink interface.
Vitoconnect, type OT2
The Vitoconnect, type OT2, can be used for single
boiler systems with an OpenTherm interface.
After commissioning Vitoconnect, type OT2, the heat
generator is operated exclusively via the ViCare app.
Room temperature settings can also be made via the
Vitotrol 100, type OT1.
Maintenance parts and spare parts
You can identify and order maintenance parts and spare parts directly online.

units: Visit www.viessmann.com/vitoconnect
IP network
System requirements
■WiFi router with activated WiFi. The WiFi router must
be protected by a sufficiently secure WPA2 pass-
word. Do not use an unencrypted connection for the
Vitoconnect and WiFi router.
■Internet connection with "flat rate" (tariff independ-
ent of time and data volume) and high availability,
i.e. the Vitoconnect is permanently linked to the
Viessmann server.
■Have the dynamic IP address (DHCP, factory setting)
on the network (WiFi) checked on site and, if neces-
sary, set up by an IT expert before commissioning.
■Determine the routing and security parameters in the
IP network (LAN) as follows: Enable port 80,
port 123, port 443 and port 8883 for direct outward
connections. Have this checked on site and, if nec-
essary, set up by an IT expert before commission-
ing.
Note
During operation, the Vitoconnect establishes a secure
internet connection to the Viessmann server. Connect-
ing the Vitoconnect to other servers is not possible.
Viessmann account
A valid Viessmann account on the Viessmann server is
required for the operation of a Vitoconnect, regardless
of which control device is used. Registration for this
takes place automatically during commissioning via the
ViCare app.
Control device for the ViCare app
The ViCare app supports mobile devices with the fol-
lowing operating systems:
■Apple iOS
■Google Android
Note
■For compatible versions: Go to the Apple App Store
or Google Play Store.
■Further information: Visit www.vicare.info
Message destinations
Mobile devices for using apps from Google Android or
Apple iOS, e.g. smartphone or tablet. Receiving push
messages must be allowed on the individual device.
Terms of use
All users will be informed by email about changes to
the terms of use and any additional information.
Installation site
Vitoconnect
Type of installation: Wall mounting
■Installation indoors only
■The installation location must be dry and frost-free.
■Ensure ambient temperatures between +5 and
+40 °C.
■Distance from the heat generator min. 0.3 m and
max. 2.5 m
■Distance to the WiFi router: Min. 0.3 m
■230 V/50 Hz Schuko socket
or
US/CA: 120 V/60 Hz outlet
max. 1.5 m from the installation site
■Internet access with an adequate Wi-Fi signal
Note
The Wi-Fi signal can be strengthened with a com-
mercially available Wi-Fi repeater.
Note
■Observe the lengths of the supplied connecting
cables when selecting the installation site.
■Keep the distance between the Vitoconnect and the
Wi-Fi router as small as possible to ensure a good
Wi-Fi connection.

Vitotrol 100, type OT1
Type of installation: Wall mounting
■On an inner wall in the main living room, approx.
1.5 m from the floor
■The installation location must be dry and frost-free.
■Ensure ambient temperatures between 0 and
+40 °C.
■Not in the immediate vicinity of doors and windows
■Not above radiators
■Not in shelving, niches etc.
■Not close to sources of heat (direct sunlight, fire-
place, television etc.)
Ranges
The range of Wi-Fi connections can be reduced by
walls, ceilings and furniture. The strength of the Wi-Fi
signal gets reduced and reception can be disturbed.
Reduction of the range:
■Wi-Fi signals get attenuated on the way from the
transmitter to the receiver, for example, through the
air and when penetrating walls.
■Wi-Fi signals are reflected by metallic parts,
for example, reinforcement in walls, metal foils of
heat insulation and metallised thermo-glass for heat
insulation.
■Wi-Fi signals are cut off by supply blocks and lift
shafts.
■Wi-Fi signals are disturbed by devices that also
work with high-frequency signals. Keep a distance of
at least 2 m to the following devices:
–Computers
–Audio and video systems
–Radio signals
–Electronic transformers
–Ballasts
Note
We recommend keeping the distance between the
Vitoconnect and the Wi-Fi router as small as possible
to ensure a good Wi-Fi connection.
