Wind and rain detection panel WRZ 40M/4G

Ventilation control panel for operating max. 40 x 230 V AC ventilation drives (e.g. M3) with a total current consumption of 8 A, split among 4 motor groups. Optional connection of vent switches and wind/rain sensors.

Benefits/Features

• Connection for up to two WRM/2 24V wind/rain sensors or up to two RM/2 24V rain sensors (type WRZ 40 M/4G)
• Connection for 230 V and 24 V vent switches
• Automatically closes windows, flaps and skylight domes operated by 230 V AC drives following wind/rain signal
• 4 potential-free relay contacts for quadrupling and forwarding a wind/rain signal (type WRZ 10 M/1G)
• Timer-controlled forwarding of the wind/rain signal, configurable via DIP switch
• Timer-controlled supply to the CLOSE drive output (ventilation function is released in spite of wind/rain signal), configurable via DIP switch (type WRZ 10 M/1G)
• Optional cascading of multiple WRZ 10M–1G to duplicate the signal; max. 4 can be cascaded with a WRZ40M-4G
• Visual status display
• Indication of the triggering of the respective detectors, separated by wind and rain
