Kingspan STG wind and rain detection center WRZ 40M/4G without “manual/automatic” switch

Ventilation center for controlling max. 40 x 230 V AC ventilation drives (e.g. type M3) with a total current consumption of 8 A, distributed over 4 motor groups. There are connection options for ventilation buttons as well as wind and rain detectors.

Special features:

• Connection for up to two wind/rain detectors WRM/2 24V or features for up to two rain detectors RM/2 24V
• Connection for 230 V and 24 V ventilation buttons
• Automatic closing of windows, flaps and skylights in conjunction with 230 V AC drives after a wind/rain report
• Time-dependent forwarding of the wind/rain signal, configurable via DIP switches
• Cascading of several WRZs (maximum 4 pieces)
• Status messages via visual display
• Display of the activation of the respective detectors, separated according to wind and rain

Areas of application/features:

• 230 V AC ventilation drives and 24 V DC wind/rain detectors
