Product and Applications Description

The central device of the weather station forms the

interface between the sensors and the bus.

The 4- and 8-sensor weather control units are central

switching and control systems which enable for

example the automatic adjustment of various

blinds/shutters.

Examples of these include the textile sun blind, external

shutters as well as interior motor-driven sun protection

systems such as venetian blinds or vertical blinds.

4 or 8 sensors can be connected to the central devices.

Apart from a special digital input for the wind sensor,

either 3 or 7 further analogue inputs are available for

the connection of light, rain, temperature and dusk

sensors.

The following accessories for the weather control units

must be ordered separately:

Dusk sensor 5WG1 258-3AB11

Temperature sensor 5WG1 258-3AB21

Light sensor 5WG1 258-3AB31

Rain sensor, heated 5WG1 258-3AB41

Wind sensor heated 5WG1 258-7AB02

Wind sensor heated n.w. 5WG1 258-7AB03

Wind sensor unheated n.w. 5WG1 258-7AB13

Heating transformer 5WG1 258-8AB01

Mast mounting for sensors 5WG1 258-8AB21

Application Programs

Weather control unit for 4 / 8 sensors

20 CO weather control unit 905202

• sun guard (shutters, venetian blinds)

• protection of building parts (windows, shutters,

a.s.o.) against rain, frost and storms

• winter garden control (sun heat can be used if

wanted)

• previous control of the heating system for reduction

of energy expenses

V WARNING

• A separate 230 V AC circuit should be used to

connect the weather control unit.

• The operating voltage 230V should only be connected

at the designated terminals.

• Only the sensors indicated may be used.

• The sensor cables may not be laid parallel to the

power cables.

• The connections to the sensors should remain non-

earthed and may not exceed 20 m in length.

• The device may not be installed in the immediate

vicinity of heating systems and air conditioning

devices.

• Both the central devices and the sensors should not

be installed in the vicinity of radio transmitters.

• The device may be opened to connect the mains

cable and the sensors. The internal cover plate may

not be removed.

• The fuse may only be replaced by a fuse of the same

type and nominal data (5x20mm 1.6AT HB).

• The device may only be installed and commissioned

by an authorised electrician.

NOTE:

The controller must only ever be reset once the fault

has been repaired (replacement of a sensor).

To reset, switch off the 230V voltage supply to the

weather central controller and the heating transformer

for at least 10 minutes.

Installation and wiring

General description

The 4- and 8-sensor weather control units are surface-

mounted using screws. The housing should be

mounted on an inside wall in an accessible position.

The devices are suitable for installation in dry and damp

interior rooms. It should be ensured that there is

sufficient space available for the supply cables.
