External sensor control
When using this control strategy, the solar shading is being controlled according to the light intensity on the facade. When the lighting level, measured on the facade where the window is located, exceeds the value of Shade Close (lux), the shading is being closed. The solar shading will remain closed until the lighting level on the facade drops below the value of Shade Open (lux).
Data in the dialog defining the control type SensorCtrl.
| Parameter | Description | Variants / interval, unit | Standard value |
|---|---|---|---|

| Shade Close | Limit for lighting level on the facade, over which the solar shading is being closed. | 3 000–80 000 lux | 20 000 lux |
| Shade Open | Limit for lighting level on the facade, below which the shading is being opened. | 2 000–20 000 lux | 10 000 lux |
