Connection and installation
Note
Transmitter and receiver communicate via radio control. The transmission range
depends on the structural conditions. Walls and ceilings, especially steel
reinforcements or metal claddings, reduce the transmission range. The distance
of components to other transmitters that also emit high-frequency signals (e.g.
computers, audio and video systems) should be at least 1 m.
Radio range
To minimize the consumption of power, battery-operated free@home wireless devices are not
operated as repeaters. Different to free@home wireless devices with mains power, a received
command is therefore not transferred.
That is why during the installation it should ensured that there is at least one free@home
wireless device with mains power supply within the range of the battery-operated device.
Planning instructions
Planning and application instructions for the system are available in the ABB-free@home
system manual. This can be downloaded at www.abb.com/freeathome.

Installation
Mounting and installation are identical for both device versions. In the following, only the
Comfort version is shown as an example.
If the device is not in factory settings, the batteries must first be inserted, (See "Inserting the
batteries" on page 16). The adjusting pin moves back and forth until the error condition "Er1" is
triggered. The thermostat can then be fitted.
Only install on common radiator valves located in dry, indoor rooms. Observe the currently valid
regulations.
Note
For the Basic version the error messages can only be viewed via the web-based
interface of the System Access Point.
