6 Initial commissioning

The quality of the wireless data communication for out-

door sensors and controllers is represented by a

number of between 0 and 10.

no reception

poor quality

10:

excellent quality

Note!

You will have to change the location of the con-

troller, wireless sensor or wireless receiver if

the value is less than 3. A description of the in-

stallation of the radio receiver unit on the wall

is provided in Section 4.4.1.

Note!

The range of radio transmission within build-

ings is largely dependent on the local conditions

(e.g. the nature of the building). This means

that a range of 25 m within the building cannot

always be guaranteed. A range of more than

100 m can be achieved outside enclosed spaces

(free field).

The quality displayed is updated automatically as soon

as changes are made. With wireless outdoor sensors this

procedure may take up to 15 minutes.

Note!

The "Learn" screen is only used for "training"

replacement components to work with in the

wireless network.

Specific operating data can be displayed and adjusted/

changed at the expert technician level. This means that

an optimum match can be found between the controller

and the heating system. This is useful, especially if the

heating installation has additional components apart

from heating circuit 1 (HC 1) (e.g. heating circuit 2, hot

water storage, solar system).

The expert technician level includes screens C1 to C26

and screens A1 to A6 as previously described.

The screens C1 to C26 appear in the VRC 430f in the

same sequence, as shown in Table 6.1 below.

This table shows you which parameters you can adjust
