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
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 a
WiFi router.
■Internet access must be available at all times.
■The user has been registered: See page 19.
■To ensure that messages can still be sent if there is a
power failure, we recommend connecting the Vito-
connect 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 implementing sup-
plementary measures, e.g. frost protection or moni-
toring for water damage.
Liability
No liability is accepted for loss of profit, unattained
savings, or other direct or indirect consequential losses
resulting from use of the Vitoconnect, the Viessmann
server or the software, or for damage resulting from
inappropriate use.
Liability is limited to typically resulting loss, if negli-
gence leads to a breach of a significant contractual
obligation, the fulfilment of which is required for proper
performance 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.
The relevant data protection regulations and terms of
use apply to the use of ViCare or Vitoguide.
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.

Installation, service and operating instructions that are
included with the products and are available online
must be observed.
Use Vitoconnect products exclusively for monitoring,
operating and optimising systems with the user interfa-
ces and communication interfaces specified for this
purpose in the relevant printed documentation. With
regard to the communication interfaces, ensure on site
that the system requirements specified in the product
documentation are met at all times for every transfer
medium employed (e.g. required WiFi connection to a
WiFi router).
Only use the specified components for the power sup-
ply (e.g. plug-in power supply units).
Note
The devices are intended exclusively for domestic or
semi-domestic use, i.e. even users who have not had
any instruction are able to operate the devices safely.
Product information
Vitoconnect is a wall mounted internet interface for
communication with the boiler control unit of the heat
generator.
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 Vitoguide.
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.
Spare parts lists
Information about spare parts can be found on the
Viessmann spare parts app.

ViCare app
You can control your heating system remotely via the
internet using an app.
For further information: Visit www.vicare.info or go to
the App Store or Google Play Store.
Vitoguide
For contractors only
Your heating system can be remotely monitored by
your contractor. For this, your contractor requires serv-
ice clearance.

Supported control units
For an up to date overview of the supported control
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 dynamic IP addressing (DHCP, factory setting)
on the network (WiFi) checked on site, and if
required set up, by an IT expert prior to commis-
sioning.
■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 and, if necessary,
set up on site by an IT expert before commissioning.
Note
During operation, the Vitoconnect establishes a secure
internet connection to the Viessmann server. Connect-
ing the Vitoconnect to any other type of server is not
possible.
User account
A valid user account on the Viessmann server is
required for the operation of the Vitoconnect, regard-
less of which control device is used. Registration is
automatic during commissioning via the ViCare app:
See page 19.
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 App Store or Google
Play Store.
■Further information: Visit www.vicare.info
Message destinations
Terminal device for receiving email, e.g. a computer,
smartphone or tablet.
Installation location
Vitoconnect
Installation type: Wall mounting
■Installation only in enclosed buildings
■The installation location must be dry and free of frost.
■Ensure ambient temperatures between +5 and
+40 °C.
■Distance to heat generator min. 0.3 m and max.
2.5 m
■Standard socket 230 V/50 Hz
or
US/CA: Socket 120 V/60 Hz
max. 1.5 m to installation location
■Internet access with adequate WiFi signal
Note
The WiFi signal strength can be increased with com-
mercially available WiFi repeaters.
Note
■Observe the lengths of the connecting cables provi-
ded when choosing the installation location.
■Install the Vitoconnect as close as possible to the
WiFi router to ensure a good WiFi connection.

Vitotrol 100, type OT1
Installation type: Wall mounting
■On an internal wall in the main living room, approx.
1.5 m above the floor
■The installation location must be dry and free of frost.
■Ensure ambient temperatures between 0 and
+40 °C.
■Not next to windows or doors
■Not above radiators
■Not between shelves, in recesses, etc.
■Not near heat sources (direct insolation, fireplace,
TV set, etc.)
Ranges
The range of WiFi connections may be reduced by
walls, ceilings and interior fixtures. These weaken the
WiFi signal and can cause poor reception.
Range reduction:
■On their way between transmitter and receiver, WiFi
signals are damped, e.g. by air or when penetrating
walls.
■WiFi signals are reflected by metallic objects, e.g.
reinforcements in walls, metal foil of thermal insula-
tion and thermal glazing with metallised thermal
vapour deposit.
■WiFi signals are isolated by service ducts and lift
shafts.
■WiFi 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
–Radio signals
–Electronic transformers
–Pre-ballasts
Note
To ensure a good WiFi connection, we recommend
keeping the distance between the Vitoconnect and the
WiFi router as short as possible.
