Wind wheel:
The wind sensor of the WRF 401/C consists of a wind wheel which, depending on the wind speed, generates a specific switching frequency which triggers a switching operation in the switching device.

Rain sensor:
On the top of the WRF 401/C's rain sensor there is a corrosion-resistant sensor plate which is connected to an AC voltage of approx. 18 - 24 V/50 Hz. The sensor plate is electrically heated so that the electrodes dry quickly, e.g. after a rainfall. If rainwater gets onto the sensor plate, a signal is sent to the wind/rain sensor and a switching operation is triggered.

The WRF 401/C wind/rain sensor must be mounted on the main weather side in an unprotected location (connect lightning protection earth electrode). Various mounting options can be realized with the special accessories. In case of rain or snowfall as well as wind, a switching signal is transmitted to the WRM 401/C switchgear ( wind/rain detector WRM 401/C).
Function check wind wheel:
Check the wind wheel for smooth running.
Functional check of rain sensor:
If the sensor plate of the rain sensor is touched with a slightly moistened hand, a rain message is sent to the switching device.

Operating voltage: 18 - 24 V/50 Hz
Housing color: wind wheel: anodized black; rain sensor: RAL 7035 (light gray)
Power consumption: approx. 1.2 W
Temperature range: -20 °C to +80 °C
Wind wheel: check annually for dirt and ease of movement
Rain sensor: annual cleaning of the sensor plate, in case of heavy environmental pollution correspondingly more frequent
Wind wheel: aluminum, polyethylene
Rain sensor: ABS, epoxy resin, galvanic gold-plated

Not compatible with WRM 401/B
