KNX DRA weather ctrl.unit [514700]
Weather control unit for KNX
Sensors

Merkmale:
Function in the Gira One system
- The components of the weather station consisting of a weather sensor and a
weather control unit cannot be used individually.
- The weather sensor has the following sensors:- Brightness from three
directions (spaced 90° apart, compass directions: east, south, west)-
Temperature- Wind speed- Precipitation sensor, with integrated heating
- The weather sensor transmits the sensor values to the weather control unit,
which evaluates the sensor information and sends it to the bus.
- Automatic visualisation of sensor information in the Gira Smart Home App.
- The weather sensor can communicate with up to 20 weather control units.
- Encrypted data transfer between the Gira One devices.

Function channels
- 2x wind alarms so that the connected blinds are raised and automatically
locked when the alarm is active. The status of the wind alarm is monitored on
a cyclical basis.
- 1x precipitation alarm so that the skylights or roof domes close immediately
and are automatically locked when the alarm is active. The status of the alarm
is monitored on a cyclical basis.
- 1x frost alarm so that active movements of shutters are stopped and locked
when the alarm is active to protect the shutter motor. The status of the alarm
is monitored on a cyclical basis.
- 4x sun protection for 4 façades with automatic sun protection function
incl. evaluation delay, for reliable sun protection function. Separate
activation/deactivation function in the Gira Smart Home App.
- 1x day/night function for switching between day/night mode incl. separate
activation/deactivation function in the Gira Smart Home App.
- Automatic information in the event of communication faults between the
weather sensor and the weather control unit.

Function in the Gira KNX system
- The weather control unit is used in combination with the weather sensor
<strong>8380 00</strong>, evaluates the sensor information and sends it to the
KNX:<br/>- Wind speed<br/>- Outdoor temperature<br/>- Brightness in lux of all
three brightness sensors incl. maximum brightness.<br/>- Precipitation
(yes/no)
- Up to 20 weather control units can be connected to one weather sensor.
- 10 sensor channels for wind, precipitation, temperature and brightness.
Logical AND/OR links can be created within the sensor channels to evaluate
multiple sensor values together.
- Evaluation delay for all sensors to ensure reliable functionality.
- 8 sun protection channels for 8 facades with automatic sun protection
function incl. evaluation delay to ensure a reliable sun protection function.
- 2 objects for external brightness sensors.
- Pre-defined day/night object for switchover between day/night mode incl.
separate activation/deactivation function via the communication object.
- Communication object that provides information about any communication
problems between the weather control unit and the weather sensor.
