WRZ 8000
Anwendung
- Lüftungssteuerung für 230VAC Lüftungsantriebe
- LED-Anzeigen für Wind und Regen, Windschwell-
wert-Überschreitung undAutomatikbetrieb I/0
- WRZ 8000 zusätzlich mit Leuchtbandanzeige für
Windstärke (Beaufort) und LED für Windsignal-
Speicherfunktion (Signal wird gespeichert, damit
dieAntriebe bei Windböen nicht ständig Laufen.)
- bei WRZ: einstellbarer Schaltpunkt der Wind-
stärke (4 oder 6 Bft.) am Wind-/Regengeber WRG
82, Signalspeicher: 10 Min.
- bei WRZ 8000: stufenloses Einstellen des Schalt-
punkts der Windstärke (2 bis 8 Bft.) und der
Signalspeicherzeit (1 bis 15 Min.) an der Zentrale
- Anschluss von bis zu 20 Gruppen über
Trennrelais TRL8 am 24 VDCAusgang möglich
- Wetterüberwachungsfunktion (zentral ZU) in Ver-
bindung mit mehreren TRL8
Application
- ventilation control for 230VAC ventilation drives
- LED-displays for wind and rain, exceeding of wind
threshold value and automatic operated ON/OFF
- WRZ 8000 in addition with luminous band for wind
force (Beaufort) and LED for wind signal memory
function (Signal is stored to avoid continously
running of the drives with gusts of wind.)
- in case of WRZ: adjustable switching point of wind
force (4 or 6 Bft.) at wind/ rain transmitter WRG 82,
signal retention time: 10 minutes
- in case of WRZ 8000: infinitely adjusting of
switching point of wind force (2 to 8 Bft.) and signa
retention time (1 to 15 minutes ) at control panel
- possibility of connecting up to 20 groups via cutoff
relays TRL8 at 24 VDC output
- weather monitoring (central CLOSE) in
conjunction with several TRL8

Summary

Application

Ventilation Control

Controls 230VAC ventilation drives based on environmental conditions.

LED Indicators and Signal Memory

Features LED displays for wind/rain and a signal memory function to prevent rapid cycling.

Adjustable Wind Settings

Allows adjustable wind force thresholds and signal retention times for WRZ and WRZ 8000 units.

Connectivity and Integration

Supports connecting up to 20 groups via TRL 8 relays and weather monitoring integration.

Mounting Notes

Wiring and Installation

Separate weak current and supply mains wiring; observe clamp sequence and VDE 0100 regulations.

Drive and Relay Connections

Connect max. 20 drives (30 VA each) or max. 20 cut-off relays TRL 8 to the 24 VDC output.

Vent Button Requirements

Use only buttons for deadman's principle operations with vent buttons.

Operation

Automatic Mode

Automatic mode functions when the green LED is lit (switch set to 'I').

Wind Operation

System closes automatically when wind speeds exceed the set threshold; red 'Wind' LED indicates.

Rain Operation

System closes automatically upon onset of rain; red 'Rain' LED indicates for at least one minute.

Temperature Control Priority

Room temperature control operates if automatic is on and no wind/rain signal is present; these signals have priority.

Technical Data

Electrical Specifications

Details mains supply (230 VAC), power consumption (30 VA), and output ratings (230V/5A, 24VDC/0.5A).

Physical Specifications

Includes housing material (PC/light grey), protective system (IP 50), temperature range (-5°C to +40°C), and dimensions.

Connection Diagram

Wiring Overview

Illustrates the connection of WRZ/WRZ 8000 with 230V drive, RTR 230, WRG 82, and TRL 8.

Troubleshooting

Provides guidance for no function with rain/wind and faulty rain/wind indication.

Example for Application

System Configuration

Shows a typical setup with ventilation drive, room temperature control, wind/rain transmitter, and cutoff relay modules.
