Vitoconnect OPTO2 Installation and Operating
Safety

Operational Safety

Vitoconnect facilitates communication over the Internet between the following components and the Viessmann server:

Vitotronic control unit (Optolink interface)
The functionality is only available if the following conditions are met:
The Vitoconnect is connected to the Internet via a Wi-Fi router.
Internet access must be available at all times.
The user has registered: see page 13.
For messages to be sent even in case of a power failure, we recommend an uninterruptible power supply for the Vitoconnect and the Wi-Fi router.
Note:
The heating system and the operability of the message channels must be checked at regular intervals.
To further increase the reliability of the heating system, we recommend planning supplementary 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 substantial contractual obligations which are deemed essential for the purpose of complying with the subject matter of the contract, liability is limited to damage typical for the contract.
The limitation of liability is not applicable if the damages were caused deliberately or with gross negligence 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.
For usage of ViCare or Vitoguide the respective data protection regulations and terms of use apply. 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 operatorapply.

Intended Use
In keeping with the intended use, Vitoconnect products should be installed and operated exclusively in conjunction with the electronic control units and controllers of the
Viessmann boilers supported for this purpose. 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 industrial use for a purpose other than for control and regulation).
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 optimization of the systems, using the user and communications interfaces defined in the printed material of the product. For the communications interfaces, it must be ensured on-site that for all the transmission media used, the system requirements 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.

Preparing for Installation

Product Information

Vitoconnect is a wall-mounted Internet interface that communicates with the control unit of the boiler.

Using an Optolink interface, the Vitoconnect type OPTO2 can be used for single-boiler systems. The Vitoconnect enables remote operation of heating systems over the Internet. For settings and queries the ViCare app is used. A qualified contractor can alternatively control the heating system via Vitoguide.

System Requirements

Supported control units
Current overview of the control units supported: go to www.viessmann.com/vitoconnect.
IP network system requirements

Wi-Fi router with activated Wi-Fi. The Wi-Fi router must be protected by a sufficiently secure WPA2 password. Unencrypted connections of the Vitoconnect to the Wi-Fi router are discouraged.
Internet connection with “flatrate” (fixed charge with unlimited time and data) with high availability, i.e. the Vitoconnect is permanently connected to the Viessmann server.
Network (Wi-Fi) with dynamic IP addressing (DHCP, delivered condition); have an IT professional check this before commissioning; set up if required.
Define the routing and security parameters for the IP network (LAN): open port 80, port 123, port 443 and port 8883 for directly outgoing connections. Have an
IT professional check this on-site before commissioning; set up if required.

Note: During operation, Vitoconnect sets up a secure Internet connection to the Viessmann server. Connections of the Vitoconnect with other servers are not possible.
User account
Regardless of the operating unit, the Vitoconnect requires a valid user account for the Viessmann server. This account is registered automatically at the time of commissioning via the ViCare app: see page 18.
Operating unit for ViCare app
The ViCare app supports end devices running one of the following operating systems:

Apple iOS
Google Android
Note:
Compatible versions: see the App Store or Google Play.
For more information go to www.vitodata.info.

Message destinations
End device for receiving email, for example computer, smartphone or tablet PC.

Vitoconnect Installation

Wall mounted indoors installation only

The installation location must be dry and frost-free.
Ensure ambient temperatures between 41°F and 104°F (+5°C and +40°C).
Distance from the boiler min. 1 ft. (0.3 m) and max. 8 ft. (2.5 m)
120 V/60 Hz outlet max. 5 ft. (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 commercially 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.

Connecting cables	Length
Wall power supply with connecting cable	5 ft. (1.5 m)

Optolink connecting cable to connect the Vitoconnect to the boiler control unit| 10 ft. (3 m)

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 metallized 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 6.5 ft. (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.
