Systeme de Regulation Automatique de Ventilation WRZ8000

WRZ8000 - Weather Control D+H

The WRZ and WRZ 8000 weather control panels are especially designed for the use in 230V ventilation systems. The system can be extended up to 20 ventilation groups by using cutoff relays TRL 8, in which each group is individually controllable via vent buttons and/or room temperature control. Due to the possibility of connecting up to 20 D+H 230V ventilation drives per group, systems can have up to 400 drives. A central weather function ensures the automatic closing of all ventilation groups in case of strong wind or rain.
