Description
The wind and rain sensor consists of a wind wheel and a rain sensor
surface. It is used for automatic control of SHEV and venting units.
The wind and rain sensor is equipped with a potential-free change-over
contact with a contact rating of 60 V/2 A.
In the event of wind and/or rain, the change-over contact switches from
normally closed contact to normally open contact.
Test setting, wind trigger threshold, actuation delay, drop-out delay and
actuation in case of power failure are set on a 6-pole DIP switch in the
sensor.

Operation/Function
Wind-triggered actuation
The potential-free contact switches when the wind sensor is actuated.
The red LED in the sensor is lit. The wind speed at which the wind
sensor is actuated is settable.
Note: Depending on your settings, the wind sensor will be reset 10 or
20 minutes after the last sensor actuation.
Rain-triggered actuation
The potential-free contact switches when the rain sensor is actuated.
The red LED in the sensor is lit.
Note:
Depending on your settings, the rain sensor will be reset 10 or
20 minutes after the last sensor actuation.
