Intended use

Install and operate the ViCare thermostatic radiator valve as intended, exclusively in conjunction with the electronic control units and controllers of the supported Viessmann heat and power generators. Also take account of the relevant installation, service and operating instructions.
In particular, observe the current and voltage specifications for connections and hook-ups. The ViCare thermostatic radiator valve is intended for operation only:

• As a standalone device
  Or
• With a Viessmann heat generator with Viessmann One Base or Vitoconnect, e.g. type OPTO2
  The values measured are sent wirelessly to the heat generator with Viessmann One Base or Vitoconnect, e.g. type OPTO2.

Incorrect usage of the device is prohibited and results in an exclusion of liability. Installation, service and operating instructions included with the product and available online must be observed.
Note
The device is intended exclusively for domestic or semi-domestic use, i.e. even users who have not had any instruction are able to operate the device safely.

Product information

The ViCare thermostatic radiator valve is a radiator actuator for individual room control. The ViCare thermostatic radiator valve records the current room temperature via an integral temperature sensor.
The ViCare thermostatic radiator valve has an internal frost protection function that prevents the pipes from freezing. If the room temperature falls below approx. 8°C, the ViCare thermostatic radiator valve opens until the temperature reaches at least 8°C again.
With the "open window detection" function, the thermostatic valve is automatically closed to save energy costs.
Note
To prevent the valve from sticking, the motor of the ViCare thermostatic radiator valve is opened and closed again every 7 days.

Preparing for installation

Installation location

• Installation only in enclosed buildings
• The installation location must be dry and free of frost.
• Ensure ambient temperatures between 0 and +40°C.
• Installation on connection adaptor on thermostatic valve
• Do not cover the ViCare thermostatic radiator valve with furniture or curtains.

Note

• Check the reception quality of the thermostatic valve at the planned installation site. To do this, before installation, pair the ViCare thermostatic radiator valve near the heat generator with Viessmann One Base or Vitoconnect, e.g. type OPTO2.
• If the reception quality is not sufficient, the wireless signal can be amplified by a wireless repeater:
  • ViCare wireless repeater for surface mounting, accessories
  • Wireless repeater for flush mounting, accessories

Range of the wireless signal

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 following circumstances.

• On their way between transmitter and receiver, wireless signals are damped, e.g. by air or when penetrating walls.
• Wireless signals are reflected by metallic objects, e.g. reinforcements embedded in walls, metal foil of thermal insulation and thermal glazing with metallised 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 distance 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 wireless 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.

Flat (unfavourable) angle of penetration

1. ViCare thermostatic radiator valve
2. Heat generator with Viessmann One Base or Vitoconnect, e.g. type OPTO2
3. Wall

Ideal angle of penetration
